Effect of gear ratio on peak power and time to peak power in BMX cyclists     

Lee P. Rylands  Simon J. Roberts  Howard T. Hurst 《European Journal of Sport Science》2017,17(2):127-131

The aim of this study was to ascertain if gear ratio selection would have an effect on peak power and time to peak power production in elite Bicycle Motocross (BMX) cyclists. Eight male elite BMX riders volunteered for the study. Each rider performed three, 10-s maximal sprints on an Olympic standard indoor BMX track. The riders’ bicycles were fitted with a portable SRM power meter. Each rider performed the three sprints using gear ratios of 41/16, 43/16 and 45/16 tooth. The results from the 41/16 and 45/16 gear ratios were compared to the current standard 43/16 gear ratio. Statistically, significant differences were found between the gear ratios for peak power (F(2,14)?=?6.448; p?=?.010) and peak torque (F(2,14)?=?4.777; p?=?.026), but no significant difference was found for time to peak power (F(2,14)?=?0.200; p?=?.821). When comparing gear ratios, the results showed a 45/16 gear ratio elicited the highest peak power,1658?±?221?W, compared to 1436?±?129?W and 1380?±?56?W, for the 43/16 and 41/16 ratios, respectively. The time to peak power showed a 41/16 tooth gear ratio attained peak power in ?0.01?s and a 45/16 in 0.22?s compared to the 43/16. The findings of this study suggest that gear ratio choice has a significant effect on peak power production, though time to peak power output is not significantly affected. Therefore, selecting a higher gear ratio results in riders attaining higher power outputs without reducing their start time.  相似文献

Redefining the meaning of teaching: A work in progress     

Therese M. Kuhs  Carol L. Flake 《The Teacher Educator》2013,48(4):310-320

Abstract

Particular elements of a new initial certification program are described. The use of inquiry, collaboration, and reflection as teaching strategies resulted in new learning for preservice teachers, experienced teachers, and university faculty involved in the program. Each partner in the endeavor indicated an increased understanding of these strategies as effective tools for teaching and learning at every level of the profession. Furthermore, a vision of professional development for experienced professionals in the context of their work with novice teachers emerged. Guidelines for the design and implementation of such programs are proposed.  相似文献   

THE IMPACT OF AN INSERVICE EDUCATIONAL PROGRAM ON THE GERONTOLOGICAL KNOWLEDGE AND ATTITUDES OF GERIATRIC RECREATIONAL SERVICE PROVIDERS     

Carol C. Riddick 《Educational gerontology》2013,39(2-3):127-135

The impact of an inservice program on practitioners’ gerontological knowledge and attitudes was examined. A nonequivalent control group design was used to conduct the study. The experimental group was made up of geriatric recreational service providers attending the first of two annual one‐week inservice educational programs. An outdoor resource management undergraduate level class served as the control group. The experimental group relative to the control group underwent a significant increase in their gerontological knowledge. Neither group experienced a significant change in their attitudes regarding the social value of the elderly or personal anxiety toward aging. The amount of change experienced in gerontological knowledge by program participants was significantly influenced by the degree of contact the individual had had with elders but not by their educational background. Educational background and degree of contact were not significantly associated with change in gerontological‐related attitudes. Implications for persons involved in designing and developing educational programs are discussed.  相似文献

Blood Pressure,Fitness, and Lipid Profiles of Rural Women in the Wellness for Women Project     

Patricia A Hageman  Carol H Pullen  Susan Noble Walker  Linda S Boeckner 《Cardiopulmonary Physical Therapy Journal》2010,21(3):27-34

Purpose: This study examined whether rural women, who had a high prevalence of prehypertension and hypertension upon enrollment in a wellness program, would also have a high prevalence of other cardiovascular disease risk factors such as low fitness and/or dyslipidemia. Methods: Data were analyzed from 225 rural women, ages 50-69, enrolled in a healthy eating and activity clinical trial. Cardiovascular health histories, fitness measures, blood pressure, and fasting blood serum samples were collected following standardized protocols at rural research offices. Chi-square and MANOVA were performed to examine differences in health characteristics, lipids, and fitness across blood pressure categories. Results: Fitness indicators of estimated VO_2max, 1-mile walk time, and resting heart rate differed between the blood pressure groups, with those in the prehypertensive and hypertensive groups having less desirable profiles than those in the normotensive group. Triglyceride levels of 150 mg/dL or greater, were observed in 36%, 32%, and 16.7% of women who had hypertensive, prehypertensive, and normal blood pressures, respectively. Conclusions: The need for routine blood pressure screenings by practitioners is reinforced by finding that rural women screened via PAR-Q and/or physician clearance had a high prevalence of prehypertensive and hypertensive blood pressures, in addition to low fitness and nonoptimal triglycerides. Practitioners need to provide counselling based on results and refer to other providers as appropriate.Key Words: blood pressure, lipids, fitness, rural women  相似文献

Landing techniques in volleyball     

Lobietti R  Coleman S  Pizzichillo E  Merni F 《Journal of sports sciences》2010,28(13):1469-1476

Knee injuries such as anterior cruciate ligament lesions and patellar tendonitis are very frequent in volleyball, and are often attributed to micro traumas that occur during the landing phase of airborne actions. The aim of the present study was to compare different jumping activities during official men's and women's volleyball games. Twelve top-level matches from the Italian men's and women's professional leagues were analysed. The jumps performed during the games were classified according to the landing technique used by the player (left or right foot or both feet together), court position, and ball trajectory. Chi-square analyses were performed to detect differences in landing techniques between the sexes, court positions, and trajectories when serving, attacking, blocking, and setting. Significant differences (P?相似文献
