The purpose of this paper is to examine the CSR practices and their implementation in the context of French professional sports clubs. In doing so, it analyses the link between the governance of sports clubs and CSR, which is viewed as a component of governance expanded to stakeholders and contributing to the creation of shared value. Drawing on interview data with key stakeholders of four professional sport clubs (football and basketball) and secondary material, the study sheds light on the determinants, the implementation as well as the impact of CSR on the governance of the professional clubs under examination.

BACKGROUND: Habitual walking speed predicts many clinical conditions later in life, but it declines with age. However, which particular exercise intervention can minimize the age-related gait speed loss is unclear. PURPOSE: Our objective was to determine the effects of strength, power, coordination, and multimodal exercise training on healthy old adults' habitual and fast gait speed. METHODS: We performed a computerized systematic literature search in PubMed and Web of Knowledge from January 1984 up to December 2014. Search terms included 'Resistance training', 'power training', 'coordination training', 'multimodal training', and 'gait speed (outcome term). Inclusion criteria were articles available in full text, publication period over past 30 years, human species, journal articles, clinical trials, randomized controlled trials, English as publication language, and subject age ≥65 years. The methodological quality of all eligible intervention studies was assessed using the Physiotherapy Evidence Database (PEDro) scale. We computed weighted average standardized mean differences of the intervention-induced adaptations in gait speed using a random-effects model and tested for overall and individual intervention effects relative to no-exercise controls. RESULTS: A total of 42 studies (mean PEDro score of 5.0 ± 1.2) were included in the analyses (2495 healthy old adults; age 74.2 years [64.4-82.7]; body mass 69.9 ± 4.9 kg, height 1.64 ± 0.05 m, body mass index 26.4 ± 1.9 kg/m(2), and gait speed 1.22 ± 0.18 m/s). The search identified only one power training study, therefore the subsequent analyses focused only on the effects of resistance, coordination, and multimodal training on gait speed. The three types of intervention improved gait speed in the three experimental groups combined (n = 1297) by 0.10 m/s (±0.12) or 8.4 % (±9.7), with a large effect size (ES) of 0.84. Resistance (24 studies; n = 613; 0.11 m/s; 9.3 %; ES: 0.84), coordination (eight studies, n = 198; 0.09 m/s; 7.6 %; ES: 0.76), and multimodal training (19 studies; n = 486; 0.09 m/s; 8.4 %, ES: 0.86) increased gait speed statistically and similarly. CONCLUSIONS: Commonly used exercise interventions can functionally and clinically increase habitual and fast gait speed and help slow the loss of gait speed or delay its onset.

Cette étude pilote cherche à tester la faisabilité de l'entraînement à la cohérence cardiaque avec des personnes atteintes d'un retard intellectuel dans le cadre d'un atelier protégé. Un entraînement à la cohérence cardiaque est proposé aux participants volontaires pour une durée de deux semaines à la prise de travail, matin et après-midi. Une appréciation des effets de ces exercices respiratoires est effectuée avant et après entraînement par la mesure d'indices de variabilité cardiaque et une évaluation de la perception du stress professionnel. La comparaison des valeurs récoltées pré et post-entraînement révèle une amélioration significative dans l'activation de la branche parasympathique. L'évaluation des valeurs du RMSSD sont inversement corrélées à l'évaluation des participants de leurs stress perçu. Ensemble, nos résultats indiquent que la population atteinte de retard intellectuel est réceptive à l'apprentissage de la cohérence cardiaque et que la baisse de leur stress est liée à une hausse de l'activité inhibitrice parasympathique, plutôt qu'à une diminution de l'activité excitatrice sympathique. Les considérations offertes par cette étude exploratoire doivent être étayées, mais permettent d'ores et déjà d'ouvrir de nouvelles perspectives dans la prise en charge de populations pour lesquelles la gestion du stress est mal adaptée.

The detection of testosterone abuse in sports is routinely achieved through the 'steroidal module' of the Athlete Biological Passport by GC-MS(/MS) quantification of selected endogenous anabolic androgenic steroids (EAAS) from athletes' urines. To overcome some limitations of the "urinary steroid profile" such as the presence of confounding factors (ethnicity, enzyme polymorphism, bacterial contamination, and ethanol), ultrahigh performance liquid chromatography (UHPLC) measurements of blood concentrations of testosterone, its major metabolites, and precursors could represent an interesting and complementary strategy. In this work, two UHPLC-MS/MS methods were developed for the quantification of testosterone and related compounds in human serum, including major progestogens, corticoids, and estrogens. The validated methods were then used for the analyses of serum samples collected from 19 healthy male volunteers after oral and transdermal testosterone administration. Results from unsupervised multiway analysis allowed variations of target analytes to be assessed simultaneously over a 96-h time period. Except for alteration of concentration values due to the circadian rhythm, which concerns mainly corticosteroids, DHEA, and progesterone, significant variations linked to the oral and transdermal testosterone administration were observed for testosterone, DHT, and androstenedione. As a second step of analysis, the longitudinal monitoring of these biomarkers using intra-individual thresholds showed, in comparison to urine, significant improvements in the detection of testosterone administration, especially for volunteers with del/del genotype for phase II UGT2B17 enzyme, not sensitive to the main urinary marker, T/E ratio. A substantial extension of the detection window after transdermal testosterone administration was also observed in serum matrix. The longitudinal follow-up proposed in this study represents a first example of 'blood steroid profile' in doping control analysis, which can be proposed in the future as a complement to the 'urinary module' for improving steroid abuse detection capabilities.

Sport activity is a determinant of health and well-being for adolescents' psychological and physic development. Early detection of traumatic lesions or pathological condition among sportive adolescent in the light of their developmental stage is of outmost importance and is best done by an interdisciplinary team. This clinical management also aims at preventing consequences of inappropriate training. The CHUV has set-up a specific sports medicine outpatient consultation clinic for adolescents in the order to provide the best integrative management of young athletes.

PURPOSE/OBJECTIVES: To survey oncology nurses and oncologists about difficulties in taking care of culturally and linguistically diverse patients and about interests in cross-cultural training.
. DESIGN: Descriptive, cross-sectional.
. SETTING: Web-based survey.
. SAMPLE: 108 oncology nurses and 44 oncologists. 
. METHODS: 31-item questionnaire derived from preexisting surveys in the United States and Switzerland.
. MAIN RESEARCH VARIABLES: Self-rated difficulties in taking care of culturally and linguistically diverse patients and self-rated interests in cross-cultural training.
. FINDINGS: All respondents reported communication difficulties in encounters with culturally and linguistically diverse patients. Respondents considered the absence of written materials in other languages, absence of a shared common language with patients, and sensitive subjects (e.g., end of life, sexuality) to be particularly problematic. Respondents also expressed a high level of interest in all aspects of cross-cultural training (task-oriented skills, background knowledge, reflexivity, and attitudes). Nurses perceived several difficulties related to care of migrants as more problematic than physicians did and were more interested in all aspects of cross-cultural training. 
. CONCLUSIONS: The need for cross-cultural training is high among oncology clinicians, particularly among nurses.
. IMPLICATIONS FOR NURSING: The results reported in the current study may help nurses in decision-making positions and educators in introducing elements of cross-cultural education into oncology curricula for nurses. Cross-cultural training should be offered to oncology nurses.

OBJECTIVES: To analyse the similarities and discrepancies between the official rheumatology specialty training programmes across Europe. METHODS: A steering committee defined the main aspects of training to be assessed. In 2013, the rheumatology official training programmes were reviewed for each of the European League Against Rheumatism (EULAR) countries and two local physicians independently extracted data on the structure of training, included competencies and assessments performed. Analyses were descriptive. RESULTS: 41 of the 45 EULAR countries currently provide specialist training in rheumatology; in the remaining four rheumatologists are trained abroad. 36 (88%) had a single national curriculum, one country had two national curricula and four had only local or university-specific curricula. The mean length of training programmes in rheumatology was 45 (SD 19) months, ranging between 3 and 72 months. General internal medicine training was mandatory in 40 (98%) countries, and was performed prior to and/or during the rheumatology training programme (mean length: 33 (19) months). 33 (80%) countries had a formal final examination. CONCLUSIONS: Most European countries provide training in rheumatology, but the length, structure, contents and assessments of these training programmes are quite heterogeneous. In order to promote excellence in standards of care and to support physicians' mobility, a certain degree of harmonisation should be encouraged.

PURPOSE: Optimal high-intensity interval training (HIIT) regimens for running performance are unknown, although most protocols result in some benefit to key performance factors (running economy (RE), anaerobic threshold (AT), or maximal oxygen uptake (V˙O2max)). Lower-body positive pressure (LBPP) treadmills offer the unique possibility to partially unload runners and reach supramaximal speeds. We studied the use of LBPP to test an overspeed HIIT protocol in trained runners. METHODS: Eleven trained runners (35 ± 8 yr, V˙O2max, 55.7 ± 6.4 mL·kg·min) were randomized to an LBPP (n = 6) or a regular treadmill (CON, n = 5), eight sessions over 4 wk of HIIT program. Four to five intervals were run at 100% of velocity at V˙O2max (vV˙O2max) during 60% of time to exhaustion at vV˙O2max (Tlim) with a 1:1 work:recovery ratio. Performance outcomes were 2-mile track time trial, V˙O2max, vV˙O2max, vAT, Tlim, and RE. LBPP sessions were carried out at 90% body weight. RESULTS: Group-time effects were present for vV˙O2max (CON, 17.5 vs. 18.3, P = 0.03; LBPP, 19.7 vs. 22.3 km·h; P < 0.001) and Tlim (CON, 307.0 vs. 404.4 s, P = 0.28; LBPP, 444.5 vs. 855.5, P < 0.001). Simple main effects for time were present for field performance (CON, -18; LBPP, -25 s; P = 0.002), V˙O2max (CON, 57.6 vs. 59.6; LBPP, 54.1 vs. 55.1 mL·kg·min; P = 0.04) and submaximal HR (157.7 vs. 154.3 and 151.4 vs. 148.5 bpm; P = 0.002). RE was unchanged. CONCLUSIONS: A 4-wk HIIT protocol at 100% vV˙O2max improves field performance, vV˙O2max, V˙O2max and submaximal HR in trained runners. Improvements are similar if intervals are run on a regular treadmill or at higher speeds on a LPBB treadmill with 10% body weight reduction. LBPP could provide an alternative for taxing HIIT sessions.

Background.- The main goals of the European Board of Physical and Rehabili-tation Medicine (EBPRM), founded in 1991 as the third speciality board of theUnion of European Medical Specialists (UEMS), are to harmonize pre-graduate,post-graduate and continuous medical education in physical and rehabilitationmedicine (PRM) all over Europe. The harmonization of curricula of the medi-cal specialities and the assessment of medical specialists has become one of thepriorities of the UEMS and its working groups to which the EBPRM contributes.Action.- The EBPRM will continue to promote a specific minimal undergraduatecurriculum on PRM including issues like disability, participation and handicapto be taught all over Europe as a basis for general medical practice. The EBPRMwill also expand the existing EBPRM postgraduate curriculum into a detailedcatalogue of learning objectives. This catalogue will serve as a tool to boostharmonization of the national curricula across Europe as well as to structurethe content of the MCQ examination. It would be a big step forward towardsharmonization of European PRM specialist training if an important number ofcountries would use the certifying MCQ examination of the Board as a part ofthe national assessments for PRM specialists.

International sport governing bodies (ISGBs) are built on the foundations of freedom of association and traditionally enjoy a large degree of autonomy in their decision-making. Their autonomy is increasingly confined, however, and their hierarchical self-governance is giving way to a more networked governance, in which different stakeholders exert power in different ways and in different contexts in a complex web of interrelationships. Taking a rationalist perspective on the autonomy of ISGBs, this article demonstrates that ISGBs are deploying strategies to safeguard their waning governing monopoly over international sport. Opting for an inductive approach, the authors present four possible conceptualizations of autonomy as applied to ISGBs, namely political autonomy, legal autonomy, financial autonomy and pyramidal autonomy. For each dimension, they describe the different strategies ISGBs wield in order to safeguard different dimensions of their autonomy. This article uses governance theories to hypothesize that the autonomy of ISGBs can be understood as 'pragmatic autonomy' since ISGBs only cede certain aspects of their autonomy under particular circumstances and when being subject to specific threats. Acting in a rationalist manner, they are able to keep control over governance developments in sport by using indirect and more subtle forms of governance.

PURPOSE: The goal of this study was to explore the effect of lifelong aerobic exercise (i.e., chronic training) on skeletal muscle substrate stores (intramyocellular triglyceride [IMTG] and glycogen), skeletal muscle phenotypes, and oxidative capacity (ox), in older endurance-trained master athletes (OA) compared with noncompetitive recreational younger (YA) athletes matched by frequency and mode of training. METHODS: Thirteen OA (64.8 ± 4.9 yr) exercising 5 times per week or more were compared with 14 YA (27.8 ± 4.9 yr) males and females. IMTG, glycogen, fiber types, succinate dehydrogenase, and capillarization were measured by immunohistochemistry in vastus lateralis biopsies. Fat-ox and carbohydrate (CHO)-ox were measured by indirect calorimetry before and after an insulin clamp and during a cycle ergometer graded maximal test. RESULTS: V˙O2peak was lower in OA than YA. The OA had greater IMTG in all fiber types and lower glycogen stores than YA. This was reflected in greater proportion of type I and less type II fibers in OA. Type I fibers were similar in size, whereas type II fibers were smaller in OA compared with YA. Both groups had similar succinate dehydrogenase content. Numbers of capillaries per fiber were reduced in OA but with a higher number of capillaries per area. Metabolic flexibility and insulin sensitivity were similar in both groups. Exercise metabolic efficiency was higher in OA. At moderate exercise intensities, carbohydrate-ox was lower in OA but with similar Fat-ox. CONCLUSIONS: Lifelong exercise is associated with higher IMTG content in all muscle fibers and higher metabolic efficiency during exercise that are not explained by differences in muscle fibers types and other muscle characteristics when comparing older with younger athletes matched by exercise mode and frequency.
