The Process of Greening Cycle as Method of Operative Environmental

The structural change of society from product-based business to service- and further to need-based business has caused the fact that work for environmental issues has spread from conventional factories and environmentally harmful production to concern services and offices as well. Almost every company has an office, so a relatively small environmental burden caused by an individual office grows remarkable already at the state level and globally even more. Motivation to work for environmental issues in an individual office could be challenging even without the fact that wasted environmental impacts bound also wasted costs. Besides cost savings, a concretely greener image of a company has its value in the B2Cas well as in the B2B-field. Consumers and clients are more and more conscious of environmental issues and demand concrete actions instead of speeches, good thoughts and meaningless certifications. Internal work for environmental issues at a strategy level is not sufficient, so operational environmental management is needed for changing old practices. This research is about the effects of operative environmental management on the greening process of an office-based business. The research is outlined to concern the operative work in the office including field sales. Target was to concretely lower the environmental impacts of Lyreco Finland and to find cost savings directly by changing the operative practices in the office and also indirectly by affecting the level of environmental knowledge of the personnel. During the greening process, the aim was also to create concrete arguments for marketing as well. The circle of greening process, which was especially created for this diploma work, was used as a method. The circle divides a year to themes and sections separated by factors of environmental impacts. Separation is based on Brett Wills’ thoughts of seven green wastes (Wills, Brett. The Green Intensions. 2009) and follows it uneasily. The circle aimed at ensuring evolutionary growth of knowledge instead of being revolutionary in the changing process. Committing personnel to the process from its start by asking ideas from them and giving them clear directions was an important part of the research of operative management. Because of working from distance, communication with personnel was operated by frequent training days and weekly greening notes via emails and intranet. Also availability for communication was an important task because of the telecommuting. Research results of this work show that operative environmental management in an officebased business today is mostly management of change. When the strategic environmental friendliness is taken into a concrete level, the most important individual factor is motivating the operating personnel. Research shows that evolutionary change is found being an efficient way to make a change. Also understanding one´s own impact on the environmental burden and on the whole greening process clearly motivates the personnel. Results show that in the operative realization of the greening process, clear directions of new working practices, being as concrete as possible, and committing personnel to follow them make the process more effective. The operative environmental management and the cycle of the greening process decrease the environmental burden and save costs. The concrete results could be used as believable arguments in marketing and therefore exploited in communication with interest groups. Commitment of the management is also one of the key factors of success in the greening process. In this research, changes in the business field by a company trade took the focus of the management away from the greening process and made the process more inefficient by decreasing the amount of training days. The circle of greening process will be used as a tool in the future, as well, and therefore it will help observe environmental impacts of a company and increase sustainable development. Commitment of management to the evolutionary environmental work helps the operating personnel lower environmental impacts, decrease costs and build a concretely greener image.

Cardiorespiratory adaptations induced by aerobic training in middle-aged men: the importance of a decrease in sympathetic stimulation for the contribution of dynamic exercise tachycardia

We investigated the effects of aerobic training on the efferent autonomic control of heart rate (HR) during dynamic exercise in middle-aged men, eight of whom underwent exercise training (T) while the other seven continued their sedentary (S) life style. The training was conducted over 10 months (three 1-h sessions/week on a field track at 70-85% of the peak HR). The contribution of sympathetic and parasympathetic exercise tachycardia was determined in terms of differences in the time constant effects on the HR response obtained using a discontinuous protocol (4-min tests at 25, 50, 100 and 125 watts on a cycle ergometer), and a continuous protocol (25 watts/min until exhaustion) allowed the quantification of the parameters (anaerobic threshold, VO2 AT; peak O2 uptake, VO2 peak; power peak) that reflect oxygen transport. The results obtained for the S and the T groups were: 1) a smaller resting HR in T (66 beats/min) when compared to S (84 beats/min); 2) during exercise, a small increase in the fast tachycardia (D0-10 s) related to vagal withdrawal (P<0.05, only at 25 watts) was observed in T at all powers; at middle and higher powers a significant decrease (P<0.05 at 50, 100 and 125 watts) in the slow tachycardia (D1-4 min) related to a sympathetic-dependent mechanism was observed in T; 3) the VO2 AT (S = 1.06 and T = 1.33 l/min) and VO2 peak (S = 1.97 and T = 2.47 l/min) were higher in T (P<0.05). These results demonstrate that aerobic training can induce significant physiological adaptations in middle-aged men, mainly expressed as a decrease in the sympathetic effects on heart rate associated with an increase in oxygen transport during dynamic exercise.

Training-related changes in the R-R interval at the onset of passive movements in humans

The aim of the present study was to determine whether training-related alterations in muscle mechanoreflex activation affect cardiac vagal withdrawal at the onset of exercise. Eighteen male volunteers divided into 9 controls (26 ± 1.9 years) and 9 racket players (25 ± 1.9 years) performed 10 s of voluntary and passive movement characterized by the wrist flexion of their dominant and non-dominant limbs. The respiratory cycle was divided into four phases and the phase 4 R-R interval was measured before and immediately following the initiation of either voluntary or passive movement. At the onset of voluntary exercise, the decrease in R-R interval was similar between dominant and non-dominant forearms in both controls (166 ± 20 vs 180 ± 34 ms, respectively; P > 0.05) and racket players (202 ± 29 vs 201 ± 31 ms, respectively; P > 0.05). Following passive movement, the non-dominant forearm of racket players elicited greater changes than the dominant forearm (129 ± 30 vs 77 ± 17 ms; P < 0.05), as well as both the dominant (54 ± 20 ms; P < 0.05) and non-dominant (59 ± 14 ms; P < 0.05) forearms of control subjects. In contrast, changes in R-R interval elicited by the racket players' dominant forearm were similar to that observed in the control group, indicating that changes in R-R interval at the onset of passive exercise were not attenuated in the dominant forearm of racket players. In summary, cardiac vagal withdrawal induced by muscle mechanoreflex stimulation is well-maintained, despite long-term exposure to training.

The impact of a training program in phonological awareness on children's early writing

This study examined the effects that a training program in phonological awareness had on the early writing skills of children in a Grade One class in the Lincoln County Separate school system. The intent of the training program was to provide consistent and systematic practice in the manipulation of the phonological structure of language. The games and activities of the training program were related to a framework of developmental phonological skills and practised in a group setting during an unstructured period of the regular classroom schedule. The training program operated three days in a six-day cycle for approximately twenty minutes a day, from November until mid-March. All children were tested at the outset and conclusion of the study to determine level of functioning in letter identification, word recognition, verbal intelligence, phonological awareness and spelling. Results of the pre-tests and post-tests were compared to determine differences between the experimental and control groups over time. In addition, a systematic analysis of the children's writing looked at the development of the spelling of regular and irregular words. The results of this study provided strong support for the hypothesis that the treatment group would progress through the stages of early writing development more quickly than children without such training. On the basis of differences between the groups over time, it was evident that training in phonological awareness had a direct positive effect on the spelling of regular words for children during the early stages of writing. The training program did not have a significant effect on the spelling of irregular words. Test results evaluating phonological awareness indicated a significant difference within each group over time but no significance between the groups during the experimental period. It would appear that the results of these tests reflect maturational changes in the child rather than causal effects of the training program. Nor did the effects of the training program transfer significantly to other aspects of language. Although some of the hypotheses considered were not supported by the study, the results do indicate that children during the early stages of writing development can benefit from a training program in phonological awareness. The theoretical direction for effective programming as a result of this study is discussed. The educational implications of training phonological awareness concurrent to beginning efforts in writing are considered.

The effects of upper extremity functional electrically stimulated (FES) exercise training on upper limb function in individuals with tetraplegia

Functional Electrically Stimulated (FES) ami cycle ergometry is a relatively new technique for exercise in individuals with impairments of the upper limbs. The purpose of this study was to determine the effects of 12 weeks of FES arm cycle ergometry on upper limb function and cardiovascular fitness in individuals with tetraplegia. F!ve subjects (4M/1F; mean age 43.8 ± 15.4 years) with a spinal cord injury of the cervical spine (C3- C7; ASIA B-D) participated in 12 weeks of3 times per week FES arm cycle ergometry training. Exercise performance measures (time to fatigue, distance to fatigue, work rate) were taken at baseline, 6 weeks, and following 12 weeks of training. Cardiovascular measures (MAP, resting HR, average and peak HR during exercise, cardiovascular efficiency) and self reported upper limb function (as determined by the CUE, sf-QIF, SCI-SET questionnaires) were taken at baseline and following 12 weeks of training. Increases were found in time to fatigue (84.4%), distance to fatigue (111.7%), and work rate (51.3%). These changes were non-significant. There was a significant decrease in MAP (91.1 ± 13.9 vs. 87.7 ± 14.7 mmHg) following 12 weeks ofFES arm cycle ergometry. There was no significant change in resting HR or average and peak HR during exercise. Cardiovascular efficiency showed an increase following the 12 weeks ofFES training (142.9%), which was non-significant. There were no significant changes in the measures of upper limb function and spasticity. Overall, FES arm cycle ergometry is an effective method of cardiovascular exercise for individuals with tetraplegia, as evidenced by a significant decrease in MAP, however it is unclear whether 12 weeks of thrice weekly FES arm cycle ergometry may effectively improve upper limb function in all individuals with a cervical SCI.

Sector-Specific Training and Mobility in Germany

This article studies mobility patterns of German workers in light of a model of sector-specific human capital. Furthermore, I employ and describe little-used data on continuous on-the-job training occurring after apprenticeships. Results are presented describing the incidence and duration of continuous training. Continuous training is quite common, despite the high incidence of apprenticeships which precedes this part of a worker's career. Most previous studies have only distinguished between firm-specific and general human capital, usually concluding that training was general. Inconsistent with those conclusions, I show that German men are more likely to find a job within the same sector if they have received continuous training in that sector. These results are similar to those obtained for young U.S. workers, and suggest that sector-specific capital is an important feature of very different labor markets. In addition, they suggest that the observed effect of training on mobility is sensible to the state of the business cycle, indicating a more complex interaction between supply and demand that most theoretical models allow for.

Implication de la voie ERK3/4-MK5 dans la phase G2/M du cycle cellulaire

La division cellulaire est influencée par les différents stimuli provenant de l’extérieur ou de l’intérieur de la cellule. Plusieurs réseaux enzymatiques élaborés au cours de l’évolution relayent l’information générée par ces signaux. Les modules MAP kinases sont extrêmement importants au sein de la cellule. Chez l’humain, 14 MAP kinases sont regroupées en sept voies distinctes intervenant dans le contrôle d’une myriade de processus cellulaires. ERK3/4 sont des homologues de ERK1/2 pour lesquelles on ne connaît que très peu de choses concernant leurs fonctions et régulation. Ces MAP kinases sont dites atypiques puisqu’elles ont des particularités structurales et des modes de régulation qui diffèrent des autres MAP kinases classiques. Ainsi, notre laboratoire a démontré que l’activité de ERK3 est régulée par le système ubiquitine-protéasome et qu’elle pourrait avoir un rôle à jouer dans le contrôle de la différenciation et la prolifération cellulaire. La première étude présentée décrit la régulation de ERK3 au cours du cycle cellulaire. Nous avons observé que ERK3 est hyperphosphorylée et s’accumule spécifiquement au cours de la mitose. Des analyses de spectrométrie de masse ont mené à l’identification de quatre sites de phosphorylation situés à l’extrémité du domaine C-terminal. Nous avons pu démontrer que la kinase mitotique CDK1/cycline B phosphoryle ces sites et que les phosphatases CDC14A et CDC14B les déphosphorylent. Finalement, nous démontrons que la phosphorylation mitotique de ERK3 a pour effet de la stabiliser. Au début de mes études doctorales, la kinase MK5 fut identifiée comme premier partenaire et substrat de ERK3. MK5 a très peu de fonctions connues. Des données dans la littérature suggèrent qu’elle peut moduler le cycle cellulaire dans certaines conditions. Par exemple, MK5 a récemment été identifié comme inducteur de la sénescence induite par l’oncogène Ras. Dans la deuxième étude, nous décrivons une nouvelle fonction de MK5 dans le contrôle du cycle cellulaire. Nous démontrons par des expériences de gain et perte de fonction que MK5 ralentit l’entrée en mitose suite à un arrêt de la réplication. Cette fonction est dépendante de l’activité enzymatique de MK5 qui régule indirectement l’activité de CDK1/cycline B. Finalement, nous avons identifié Cdc25A comme un nouveau substrat in vitro de MK5 dont la surexpression supprime l’effet de MK5 sur l’entrée en mitose. En conclusion, nos résultats décrivent un nouveau mécanisme de régulation de ERK3 au cours de la mitose, ainsi qu’une nouvelle fonction pour MK5 dans le contrôle de l’entrée en mitose en réponse à des stress de la réplication. Ces résultats démontrent pour la première fois l’implication de ces protéines au cours de la transition G2/M. Nos travaux établissent de nouvelles pistes d’études pour mieux comprendre les rôles encore peu définis des kinases ERK3/4-MK5.

L'intégration et la mise en oeuvre de la pratique de différenciation pédagogique chez les enseignants québécois du premier cycle du secondaire

La présente recherche de type qualitatif veut décrire, analyser et comprendre la pratique de différenciation pédagogique chez des enseignants québécois du premier cycle du secondaire. Cette pratique s’insère au cœur des programmes de formation dont la principale visée est la réussite pour tous. Cependant, elle est constituée d’un flou théorique qui la rend parfois difficile à définir et à mettre en application, particulièrement chez les enseignants du secondaire. Ce travail dresse donc le portrait de trois enseignantes du premier cycle du secondaire qui choisissent tout de même de la comprendre et de la mettre en œuvre. À ce titre, l’étude des pratiques sous l’angle du travail tel que décrit par Tardif et Lessard (1999) permet de cerner la nature complexe et composite de leur travail et de tenir compte des facteurs personnels, internes et externes qui régissent leur travail d’adaptation des programmes, appelé travail curriculaire. Ainsi, une grille d’analyse inédite, construite au regard de ces facteurs et à partir des concepts inhérents à la différenciation pédagogique, permet d’étudier trois cas de manière complète et approfondie. De manière générale, l’analyse des facteurs personnels, internes et externes à la pratique de différenciation pédagogique des enseignantes donnent des informations pertinentes sur leurs façons de différencier, sur leur motivation à différencier et sur l’influence de leur milieu de travail dans l’exercice de cette pratique. Ces résultats permettent non seulement de mieux comprendre cette pratique effectuée par des enseignants du secondaire, mais permet aussi l’élaboration des principaux facteurs pouvant faciliter sa mise en œuvre ou au contraire la limiter. Au final, les propos recueillis chez les enseignantes interrogées signalent qu’au-delà de la réussite éducative, d’autres éléments entrent en jeu dans l’exercice de cette pratique. En fait, malgré plusieurs contraintes liées aux ressources matérielles, organisationnelles et humaines, la pratique de différenciation pédagogique génère entre autres une grande source de motivation scolaire pour les élèves et contribue à augmenter la satisfaction professionnelle de ces enseignantes dans leur travail au quotidien.

Les effets d’un cercle pédagogique sur le regard professionnel et les pratiques pédagogiques des enseignants du 3e cycle du primaire en grammaire actuelle

Notre recherche doctorale vise à décrire les effets d’un cercle pédagogique sur les pratiques pédagogiques et didactiques d’enseignants du 3e cycle du primaire en grammaire actuelle. Ce projet s’inscrit dans une recherche plus large intitulée « Étude des effets, sur les pratiques pédagogiques des enseignants et la compétence à écrire des élèves, d’un dispositif de formation à la grammaire nouvelle qui intègre des exemples de pratiques sur vidéo et permet un partage d'expertise ». Elle vise à éclairer les conditions d’efficacité d’une formation continue sur différentes dimensions du développement professionnel au regard de la formation elle-même et de son effet sur le transfert des pratiques en classe. Pour y parvenir, nous avons analysé les échanges provenant des cercles pédagogiques vécus durant une année scolaire. Nous avons également analysé deux activités de grammaire, avant et après la formation en grammaire offerte sous forme de capsules. Ces observations en classe ont été captées sur vidéo, dans la classe de 18 enseignants participant à notre expérimentation. Nous avons enfin analysé les réponses des participants à un questionnaire sur leur perception à l’égard du dispositif de formation auquel ils ont participé pendant neuf mois. Nos analyses montrent qu’un dispositif de formation à la grammaire actuelle qui met au cœur de la formation l’analyse d’exemples de pratiques sur vidéo soutient le développement du regard professionnel des enseignants dans le contexte du cercle. Ceux-ci observent plus d’interactions et les interprètent mieux, de manière plus approfondie. Nos observations ont également montré que les enseignants développent majoritairement des pratiques dans leur classe, qu’ils développent de nouveaux savoirs en lien avec le cadre théorique de la nouvelle grammaire et qu’ils modifient la vision qu’ils ont de la grammaire actuelle au fil des rencontres. Cette recherche peut enrichir les connaissances scientifiques sur le développement professionnel et influencer les formateurs d’enseignants de même que les cadres des milieux scolaires pour ajuster l’offre de formation continue afin de la rendre plus efficace.

Conception d’un guide d’élaboration d’une épreuve de mathématiques dans une visée certificative pour la fin du cycle primaire au Burkina Faso

La présente recherche s’inscrit dans la mouvance actuelle orientée vers l’approche par compétences (APC) en Afrique de l’ouest. Née des exigences économiques et professionnelles à l’échelle mondiale, l’APC a connu son essor dans les années 1990. Par conséquent, le mode de recrutement sur le marché de l’emploi est basé sur les compétences des postulants. Il était donc légitime que l’école intègre cette nouvelle donne afin que les finissants puissent remplir les exigences socioprofessionnelles en temps opportun. De Ketele (2001, dans Hirtt 2009, p.6) est de cet avis quand il soutient que : « c’est en effet le monde socio-économique qui a déterminé la notion de compétence parce que les adultes que l’école a formés n’étaient pas suffisamment aptes à entrer dans la vie professionnelle ». L’APC rompt donc le caractère insulaire de l’école en faisant intervenir de nouveaux enjeux au niveau de l’enseignement, de l’apprentissage, des pratiques évaluatives des enseignants et des encadrements légaux dans les pays qui l’ont adoptée. Pour des contraintes socioéconomiques, le Burkina Faso a résolument opté de mettre en oeuvre une approche éclectique qui emprunte à l’APC certaines bases didactiques et pédagogiques. Cette option vise à doter le système éducatif burkinabé de mécanismes efficaces et efficients pour un enseignement de qualité tout en assurant la réussite et l’intégration socioprofessionnelle du plus grand nombre des sortants de l’école. Notre étude se situe dans cette nouvelle donne et vise l’amélioration du processus d’évaluation des élèves en fin du cycle primaire. Pour ce faire, nous avons conçu et validé un guide d’élaboration d’épreuves de mathématique dans une visée certificative pour ledit niveau afin de soutenir prioritairement les agents chargés de l’élaboration des épreuves officielles. En nous basant sur le paradigme de l’apprentissage, le constructivisme et la démarche méthodologique de Loiselle et Harvey (2009), nous avons examiné, dans un premier temps, les épreuves nationales développées au Québec et au Burkina Faso. Cette analyse a permis d’en relever les caractéristiques et d’identifier les éléments devant être retenus dans le cahier des charges au regard du profil des sortants défini dans le programme burkinabé. Dans un deuxième temps, un cahier des charges (version initiale.) a été développé en quatre sections afin de présenter les principes qui le sous-tendent : (1) l’élaboration des situations d’évaluation, (2) l’élaboration des outils d’administration de l’épreuve, (3) l’élaboration des outils de correction et de consignation et (4) les grilles d’évaluation. Dans un troisième temps, un groupe d’experts canadiens et deux groupes d’experts burkinabé se sont exprimés sur le degré de pertinence et de clarté de chaque section à partir de l’une ou l’autre version du Guide. Leurs observations et commentaires nous ont permis de le bonifier. D’une manière générale, les pourcentages des degrés d’accord pour la pertinence et la clarté des contenus développés au niveau de chaque section sont satisfaisants. Cependant, les recommandations des experts ont suscité des ajustements sur : 1) le contenu du guide soit de conserver une seule épreuve en mathématiques et de retirer les énoncés concernant les volets lecture et écriture en français; 2) le contenu de certains tableaux : à compléter ou à fusionner et; 3) la qualité de la langue : certaines phrases ont été reformulées, les erreurs de numérotation de certaines sous-sections ont été corrigées. La version finale serait celle qui est adaptée au contexte burkinabé. Ce guide est destiné aux structures chargées de l’évaluation des apprentissages et des acquis des élèves au Burkina Faso. Il constitue aussi un référentiel pour la formation initiale et continue des enseignants et des encadreurs. Bien que la recherche ait rempli des conditions méthodologiques et éthiques, la mise en oeuvre de ses résultats se limite au contexte burkinabé. Cependant, ils pourront soutenir ou orienter d’autres recherches qui s’inscrivent dans la même dynamique.

Methods of generating carrier-envelope-phase stabilized, intense, few-cycle laser pulses

Ultrafast laser pulses have become an integral part of the toolbox of countless laboratories doing physics, chemistry, and biological research. The work presented here is motivated by a section in the ever-growing, interdisciplinary research towards understanding the fundamental workings of light-matter interactions. Specifically, attosecond pulses can be useful tools to obtain the desired insight. However access to, and the utility of, such pulses is dependent on the generation of intense, few-cycle, carrier-envelope-phase stabilized laser pulses. The presented work can be thought of as a sort of roadmap towards the latter. From the oscillator which provides the broadband seed to amplification methods, the integral pieces necessary for the generation of attosecond pulses are discussed. A range of topics from the fundamentals to design challenges is presented, outfitting the way towards the practical implementation of an intense few-cycle carrier-envelope-phase stabilized laser source.

The undergraduate level (1st study cycle) as a fundamental platform/ standard for the development of Urban and Regional Planning in higher education programs

The ongoing reforms, which were introduced under the Bologna Process and have already been extended outside of Europe , are a unique opportunity for reinforcing and structuring a common platform of understanding among members, based on the full time undergraduate courses in ( Urbanismo) Urban and Regional Planning. The training programs at this 1st cycle level, will obviously continue with the 2nd and 3rd cycles (Bachelor's Degree, Master's Degree and PhD Degree or 3+2+3 years). The training programs at this full time 1st cycle level, can also becomes the framework of understanding for the development of research in the urban fields at national and international levels.

Indexes of power and aerobic capacity obtained in cycle ergometry and treadmill running: comparisons between sedentary, runners, cyclists and triathletes

The objectives of this study were: a) to determine, in a cross-sectional manner, the effect of aerobic training on the peak oxygen uptake, the intensity at O2peak and the anaerobic threshold (AnT) during running and cycling; and b) to verify if the transference of the training effects are dependent on the analized type of exercise or physiological index. Eleven untrained males (UN), nine endurance cyclists (EC), seven endurance runners (ER), and nine triathletes (TR) were submitted, on separate days, to incremental tests until voluntary exhaustion on a mechanical braked cycle ergometer and on a treadmill. The values of O2peak (ml.kg-1.min-1) obtained in running and cycle ergometer (ER = 68.8 ± 6.3 and 62.0 ± 5.0; EC = 60.5 ± 8.0 and 67.6 ± 7.6; TR = 64.5 ± 4.8 and 61.0 ± 4.1; UN = 43.5 ± 7.0 and 36.7 ± 5.6; respectively) were higher in the group that presented specific training in the modality. The UN group presented the lower values of O2peak, regardless of the type of exercise. This same behavior was observed for the AnT (ml.kg-1.min-1) determined in running and cycle ergometer (ER = 56.8 ± 6.9 and 44.8 ± 5.7; EC = 51.2 ± 5.2 and 57.6 ± 7.1; TR = 56.5 ± 5.1 and 49.0 ± 4.8; UN = 33.2 ± 4.2 and 22.6 ± 3.7; respectively). It can be concluded that the transference of the training effects seems to be only partial, independently of the index (O2peak, IO2peak or AnT) or exercise type (running or cycling). In relation to the indices, the specificity of training seems to be less present in the O2peak than in the IO2peak and the AnT.

Effects of aerobic endurance training status and specificity on oxygen uptake kinetics during maximal exercise

The main purpose of this study was to analyze the effects of exercise mode, training status and specificity on the oxygen uptake ((V)over dot O-2) kinetics during maximal exercise performed in treadmill running and cycle ergometry. Seven runners (R), nine cyclists (C), nine triathletes (T) and eleven untrained subjects (U), performed the following tests on different days on a motorized treadmill and on a cycle ergometer: (1) incremental tests in order to determine the maximal oxygen uptake ((V)over dot O-2max) and the intensity associated with the achievement of (V)over dot O-2max (I(V)over dot O-2max); and (2) constant work-rate running and cycling exercises to exhaustion at I(V)over dot O-2max to determine the effective time constant of the (V)over dot O-2 response (tau(V)over dot O-2). Values for (V)over dotO(2max) obtained on the treadmill and cycle ergometer [R=68.8 (6.3) and 62.0 (5.0); C=60.5 (8.0) and 67.6 (7.6); T=64.5 (4.8) and 61.0 (4.1); U=43.5 (7.0) and 36.7 (5.6); respectively] were higher for the group with specific training in the modality. The U group showed the lowest values for VO2max, regardless of exercise mode. Differences in tau(V)over dot O-2 (seconds) were found only for the U group in relation to the trained groups [R=31.6 (10.5) and 40.9 (13.6); C=28.5 (5.8) and 32.7 (5.7); T=32.5 (5.6) and 40.7 (7.5); U=52.7 (8.5) and 62.2 (15.3); for the treadmill and cycle ergometer, respectively]; no effects of exercise mode were found in any of the groups. It is concluded that tauVO(2) during the exercise performed at I(V)over dot O-2max is dependent on the training status, but not dependent on the exercise mode and specificity of training. Moreover, the transfer of the training effects on tau(V)over dotO(2) between both exercise modes may be higher compared with (V)over dot O-2max.
