Exercise testings are widely used to estimate current functional state of athletes and reveal their pros and cons in particular cases. The aim of the proposed research was to evaluate eligibility, validity and informativity of various methods of exercise testing for control of athletes’ physical performance. Thirty qualified athletes aged 14 to 35 years and their level of exercise performance were studied, effective method of functional testing for control of training process was developed. We justified use of exercise testing by means of RAMP-protocol cycle spiroergometry for evaluation of aerobic capacity and exercise performance in elite and amateur athletes. Practical outcome is development of effective protocols of exercise testing for adequate and reproductible estimation of aerobic capacity and exercise performance of athletes of all qualification level and specialization. / Проведение проб с дозированной физической нагрузкой позволяет объективно оценивать текущее функциональное состояние организма, выявлять недостатки и преимущества атлетов в отдельных конкретных случаях. Цель – оценить целесообразность, валидность и информативность различных методов нагрузочного тестирования для контроля физической подготовленности спортсменов. В результате исследования были изучены методики нагрузочного тестирования 30 квалифицированных спортсменов от 14 до 35 лет, оценен уровень общей физической работоспособности, разработана эффективная методика функционального тестирования для управления тренировочным процессом. Научная новизна исследования состоит в обосновании использования нагрузочного тестирования методом велоэргоспирометрии по протоколу с непрерывно возрастающей нагрузкой для оценки аэробной производительности и функциональной готовности как элитных спортсменов, так и спортсменов-любителей. Практическая значимость работы заключается в разработке эффективных протоколов нагрузочного тестирования для адекватной и воспроизводимой оценки аэробной производительности и функциональной готовности спортсменов всех уровней квалификации и специализации.

Today American society is becoming more sedentary than any other generation before. This shift in society has shown a decrease in exercise activity. The purpose of this study was to evaluate psychobehavioral factors in relation to exercise adherence and well being. Participants (N= 80) were self-selected based upon one's enrollment into one of eight selected Physical Education Fitness Wellness (PEFWL) walking courses. This study employed a pretest-intervention-post-test quasi-experimental design, which evaluated barriers to habitual physical activity, demographics, exercise decisional balance, exercise enjoyment, exercise processes of change, stages of change for adopting physical activity, and social support in relation to current exercise patterns via a 128-item online questionnaire. Data was analyzed using 2 x 2 (Stage x Time) ANOVA and dependent t-tests with a level of significance set at p <.05. The results indicated there was a significant increase in self-efficacy from pre to post testing. No significant differences were found in pre and post testing levels of exercise enjoyment, decisional balance, social support, and the pros and cons of decisional balance in relation to physical activity parameters. / School of Physical Education

This study examined the effect of a moderate intensity exercise training program on daily physical activity levels of previously sedentary and habitually active adults. Previously sedentary subjects wore a pedometer while completing a seven consecutive day baseline physical activity measurement. After the seven day baseline trial, they received a traditional exercise prescription for 6 weeks while continuing to wear the pedometer every day. Habitually active subjects wore a pedometer for seven consecutive days while continuing their normal daily and exercise routines. Results showed that the previously sedentary subjects increased their physical activity levels by approximately 2,000 steps/day after starting a structured exercise program. On the non-exercise days, there was little to no change in physical activity levels (7,354 ± 2,344 steps/day) for the sedentary subjects when compared to the baseline daily physical activity levels (7,232 ± 1,692 steps/day). The habitually active group showed significantly higher (p<0.05) physical activity levels (12,389 ± 3,391 steps/day) when compared to the sedentary group's 6`h week physical activity levels (9,697 ± 2,212 steps/day). In addition, the habitually active group showed similar physical activity levels on non-exercise days (8,780 ± 3,295 steps/day) when compared to the sedentary group's 6`h week physical activity on non-exercise days (7,354 ± 2,344 steps/day). In conclusion, in previously sedentary subjects, a moderate intensity exercise program resulted in a significant increase in daily physical activity but not to the level of the habitually active subjects. / School of Physical Education, Sport, and Exercise Science
