Capacidade de força dos membros superiores em competidores de montaria em touros

This study did evaluate the handgrip strength capacity of bull riding practitioners and recreational practitioners in order to obtain parameters of the muscular fitness of subjects undertaken this sports practice. Twenty right-handed subjects were grouped into bull riding athletes (10 individuals at AMT: 174.5 ± 5.2 cm of height, 78.9 ± 12 kg of body weight, 24.7 ± 6.1 years, and 13,8 ± 2.4% for body fat) and non-athletes (10 subjects n-AMR: 178.5 ± 7.3 cm of height, 81.2 ± 8.8kg of body weight, 21.7 ± 2.3 years, and 13.8 ± 1.9% of body fat). They were underwent to protocols of handgrip strength evaluation by a standard and specific dynamometry (simulating a bull riding posture) of right (DPD e DED) e left (DEP e DEE) hands. The dynamic force values from one repetition to maximum test (1RM) were either obtained in conventional load-based system for upper limbs exercises. The values were compared by the test-t for independent data, assuming ρ ≤ 0.05. The relationship between the values of strength from handgrip and dynamic exercises were drawn by Pearson correlation. The results of the AMT to DPD (43.8 ± 6.8kgf), DPE (39.4 ± 7.7kgf), DED (44.9 ± 5.6kgf), and DEE (39.8 ± 8.3kgf). For the n-AMT in DPD (47.0 ± 3.0kgf), DPE (42.2 ± 6.1kgf), DED (49.2 ± 1.5kgf), and DEE (46.2 ± 4.1kgf). Significant difference was observed between DED and DEE. The strength tests of 1RM at bench press (73.2 ± 12.0kg and 82.0 ± 12.0kg), arm-curl (45.2 ± 8.9kg and 43.8 ± 8.9kg), triceps pulley (67.0 ± 6.3kg and 72.0 ± 6.3kg), and pulley (73.5 ± 8.5kg and 73.7 ± 7.5kg) for groups n-AMT and AMT did not showed differences. Correlations were showed between all handgrip tests and elbow flexor force for AMT, and between DPD and elbow extensor, abductor, adductor and extensor of shoulder for n-AMT. influences to the performance of the force dynamometry. It could be concluded that handgrip force and dynamic strength of upper limbs did not were putative responses for bull riding practice.

O tipo de trajetória não afeta o controle visual da freada em ciclistas

Braking visual control was studied in recreational cyclists through the manipulation of bicycle’s velocity at braking initiation (low, medium, and high) and approaching trajectory (straight and curved) with respect to a stationary obstacle. The hypothesis was that the type of trajectory, exclusively or interacting with initial velocity, would affect time to collision visual information (tau margin) and its fi rst derivative in time (tau-dot), respectively, in the onset and during braking. The results revealed that velocity affected signifi cantly tau margin while tau-dot remained unaltered independently of condition. The type of trajectory clearly did not affect the visual control of braking in cyclists.

Origami e kirigami: arte e cultura como recurso lúdico e educativo

We can know a people through their cultural and artistic assets. One of the many aspects of Japanese culture is origami, a fusion of the verb “oru”, which means folding, with the word “kami” meaning paper. In this communication, we describe the course “Origami and Kirigami: art and culture as a recreational and educational resource”. The course aimed to present these two oriental techniques based on paper and its potential as a source of entertainment and education, at the same time seeking to introduce cultural aspects of these arts of folding and/or cutting paper. This practice is more common than we realize, and is present in our day-to-day life when we perform actions such as folding clothes and papers, and making packages, amongst others. However, few are aware of the benefits that this folding brings to the fields of Arts, Mathematics, and Science, besides its recreational characteristics. Kirigami is a mixed technique that in addition to using folds in the paper (as in origami) also uses cuts (“kiru” – meaning, “cut”). It can be performed with heavier paper than origami, and by introducing some cuts, the paper can be folded to form the desired shape. It is a simple technique, with impressive results. We conducted eight weekly meetings, each lasting four hours, totaling 32 hours of coursework. In addition to the classes, a visit was made to the Okinawa Club in Bauru (São Paulo), where it was possible for the students of the course and the elderly group (fujinkai) of origamists of the club to exchange experiences. Finally, an exhibition was organized to display the artifacts produced by the course participants and disseminate the work of the students.

Evaluation of the best-designed graded exercise test to assess peak treadmill speed

This study examined the influence of different speed increments during treadmill exercise tests on peak treadmill speed (Vpeak) and its relationship with a 1-h treadmill running performance. 18 male recreational and amateur runners (10-km running pace: 10–15 km·h−1) performed, in an alternate order, 3 continuous incremental exercise tests with different speed increments (0.5, 1.0 and 2.0 km·h−1) on a motorized treadmill to determine Vpeak. Thereafter they undertook a 1-h time trial on a treadmill. Vpeak was determined as either (a) the highest speed that could be maintained for a complete minute (Vpeak-60 s), (b) the speed of the last complete stage (Vpeak-C), or (c) the speed of the last complete stage added to the product of the speed increment and the completed fraction of the incomplete stage (Vpeak-P). The Vpeak values were highly influenced by the different speed-incremented rates and the Vpeak-P determined during the protocol comprising speed increments of 1 km·h−1 presented the highest correlation with 1-h time trial performance (r=0.89). The results suggest that a protocol with speed increments comprising 1 km·h−1 and with a 3-min stage duration should be used as standard for the determination of Vpeak to assess aerobic fitness and predict endurance performance in recreational runners. Furthermore, the Vpeak-P should be used for the determination of Vpeak.

Reproducibility of heart rate and rating of perceived exertion values obtained from different incremental treadmill tests

Objective The present study aimed to examine the reproducibility of heart rate (HR) and rating of perceived exertion (RPE) values obtained during different incremental treadmill tests. Equipment and methods Twenty male, recreational, endurance-trained runners (10-km running pace: 10–15 km·h−1) performed, in a counterbalanced order, three continuous incremental exercise tests with different speed increments (0.5 km·h−1, 1 km·h−1 and 2 km·h−1). Thereafter, each participant performed the three tests again, maintaining the same order as before. The reproducibility of the HR and RPE values were analyzed for all protocols during submaximal intensities (8, 10, 12, and 14 km·h−1). In addition, it was examined the reproducibility of maximal HR (HRmax) and peak RPE (RPEpeak). Results The variability of both the HR and RPE values showed a tendency to decrease over the stages during the incremental test and was not or slightly influenced by the incremental test design. The HR at 14 km·h−1 and HRmax presented the highest reproducibility (CV < 2%). In contrast, the submaximal RPE values showed higher variability indices (i.e., CV > 5.0%). In conclusion, the HR values were highly reproducible during the stages of the incremental test, in contrast to the RPE values that presented limited reproducibility.

Humanização da saúde: impacto de estratégias lúdicas e anímicas no estado de humor de trabalhadores do SUS

Humanization is a decisive factor for the positive conditions in the work environment related to the health sector, however, few initiatives take into consideration this aspect in different areas of knowledge, including the field of Human Kinetics. Thus, this study, which has a qualitative nature, aimed to identify the mood of employees from Sistema Únicos de Saúde - SUS, using evidences based on experiences of a playful and animistic activities. The study was conducted through bibliographical and exploratory research, using as a tool two-phase data collection the Brunel Questionnaire (BRUMS). Part of this study included an international sample compose of SUS participants from Araras city, having as criteria employees associated with SUS longer than one year. Participants experienced an animistic and recreational activities program and the instrument was applied before and after these experiences. Data was descriptively analyzed through the Thematic Content Analysis Technique. The results showed that the recreational and animistic activities can positively improve the mood of workers in the health sector, indicating the importance of developing new humanization strategies in health ambit. This study suggests new actions in public policy, able to encourage longer or even continuous interventions in the daily journey of health workers

Uso de substâncias ergogênicas suplementares nutricionais em praticantes de musculação

Ergogenic substances are all nutritional or pharmacological additional devices which physiologically influence on the individual's performance. Currently, the practice of physical exercises that modern gyms have is growing and embracing a new recreational space for the population. In particular, for the male audience, weight training; and for the female audience, aerobic gymnastics. This study has the objective of explaining the importance of ergogenic resources in the physiological and psychological planes, emphasizing the point that supplementation is really valid and beneficial. To achieve the objective of the study, a literature review will be carried out, searching for scientific articles published in books, magazines and online newspapers that address some issues that cut across the thematic proposed in this work. From the point of view of Sport Psychology, the issues discussed on body image and emotional changes have concerns professionals of this area, but the literature suggests it is unnecessary the use of ergogenic substances to the concreteness of that purpose. Supplements of any kind will not be enough to transform the psychological and physiological aspects, the way the media assume conclusively. Thus, with our documentary research, we started a provocation that feeds new studies in the area. We conclude that supplementation is a resource that should be used in the final occasion, that is, if the bodybuilders (non-athletes) have time to be nourished from the normal diet, the use of supplements like whey and creatine, are not needed. Used appropriately supplements do not result in physiological damage, however, can contribute beneficially to the individual's nutrition, thus the abusing dosages, in addition to financial loss, can cause damage to the body

Doping e suplementação no MMA: um estudo documental de caso

The first records of the use of substances that enhance athletic performance began in antiquity. The objective of this study is to analyze the use of doping methods and supplements by amateur athletes and MMA professionals and what motivates usage. The work consisted of desk research in which use of work carried out at fifteen amateur and professional athletes, which underwent a data collection; these athletes are all over eighteen years old, male and practicing MMA for at least two years. The questionnaire that they were submitted corresponded to ten multiple-choice questions, which are: Age, what type of fight practiced as a basis for MMA, how long practices martial arts, sees the sport of competitive or recreational way, has already made use dietary supplements, have made use of banned substances (steroids) in the sport, it has already made use of steroids which the substance used and to what end was done using, know the side effects of anabolic steroids, know one or more people who have already made use of steroids in order to increase their performance in the fight, he believes it is possible an athlete achieve success in modern MMA without the use of anabolic steroids. The results showed that, of the fifteen athletes interviewed, only two said they never made use of dietary supplements, and four said they have already made use of anabolic steroids. All fifteen athletes claim to know the side effects of steroid use, and 14 of them say they know one or more sport-mates who have already made use of steroids. Given the results, it can be concluded that the use of steroids is common in MMA

Gonadal Maturation in the Cobia Rachycentron canadum from the Northcentral Gulf of Mexico

Gonadal maturation of cobia, Rachycentron canadum, was evaluated by examining 508 specimens from its recreational fishery. Specimens were collected off southeast Louisiana to northwest Florida by hook-and-line during February through October 1987-1991. Fork lengths (FL) of these fish ranged from 580-1,530 mm, with corresponding weights of 2.0-43.5 kg. The female:male ratio was 1:0.37. Using a combination of oocyte size frequency and histological assessment of many of the fish, we determined that females were ripe from May through September, with atretic oocytes occurring in some fish from July through October. Degenerating hydrated oocytes in July and October and the presence of resting ovaries in July suggest two major spawning periods; however, monthly gonosomatic indices peaking in May, followed by a steady decline, do not support that finding. Ovaries were placed into undeveloped, early developing, mid-developing, or late developing categories based upon oocyte size-frequency distributions. Developing ovaries had two or three modes of oocytes larger than 30 μm. Batch fecundity was estimated to be 2.6×106 - 1.91×108 oocytes, depending on the size of fish/ovaries. The smallest female with oocytes exhibiting vitellogenesis was 834 mm FL. This fish was 2 years old based its otolith evaluation. The smallest male with an abundance of spermatozoa in its testes was 640 mm FL and 1 year old based on otolith evaluation; smaller males were not examined. Females larger than 840 mm FL had vitellogenic oocytes in March and April. A few fish still had vitellogenic oocytes in early October, but none did by late October. When Gilson’s fluid was used to assess ovarian tissue, the fresh weight of the tissue was reduced by 20% after being stored for 3 months. The diameter of oocytes shrunk about 25% in Gilson’s fluid which was 11% less than those fixed in formalin, embedded in paraffin, and sectioned. Tissue sections from specific individuals, each demonstrating a variety of different developmental stages, were similar regardless of whether they were obtained from the anterior, middle, or posterior portion of either ovary.

An Overview of Historical Beaver Management in Arizona

In the mid-1820s, Anglo-American fur trappers, known as "mountain men," entered Arizona and began trapping beaver (Castor canadensis). In Arizona there have been a number of famous mountain men such as Sylvester and James Pattie, Ewing Young, Jededia Smith, and Bill Williams who trapped along the waterways in northern and southern Arizona. Although the heyday of mountain men lasted only a few decades due to a population decline of beaver, management of these animals continues to this day. The purpose of managing beavers shifted from monetary gain to controlling wildlife damage. During the late 1900s, beaver were still widely distributed in limited numbers throughout much of the state. We provide a historical overview of beaver management in Arizona with emphasis on the mountain men, recreational trapping, wildlife damage management, and beaver research in Arizona.

501(C)(3) Nonprofit Organizations in Nebraska: 2008

Nonprofit organizations are important to the quality of life in communities. They exist in complex variety and include church congregations, private schools, service clubs, business leagues, social and recreational clubs, labor unions, farm bureaus, community theaters, neighborhood organizations and many more. Only the largest of nonprofits are likely to have employees, with most relying upon volunteers to meet their human resource requirements. They obtain their financial resources through donations, investments, grants and fee based activities, such as festivals and educational programs.
