One hundred and eighteen women, aged 29 - 45 yrs, were assigned to an experimental group (EG) or a control group (CG), and completed two similar sets of tests before and after seven months of training. The EG performed two Newcomb ball training sessions per week that included technical and tactical drills with and without the ball, small sided games and full games at different variations. The CG remained non-active throughout the seven months. Leg power, arm power, agility, speed, and aerobic scores were significantly higher for the EG compared to the CG at baseline (<em>p</em> < 0.001 for all). EG showed significant training-related improvement in arm power (5.3 ± 0.9 vs 5.6 ± 0.9 m), agility (10.68 ± 0.95 vs 10.37 ± 0.89 sec), speed (4.11 ± 0.45 vs 4.01 ± 0.33 sec), and aerobic fitness (563 ± 328 vs 680 ± 378 m) (ES = 0.45 – 0.61, <em>p</em> < 0.001 for all), while no significant changes, except for a significant increase in arm power (ES = 0.42, <em>p</em> < 0.05), were found for the CG in any of the other fitness variables. The findings indicate that amateur Newcomb ball training can be used as an efficient and enjoyable tool for fitness development among midlife women.展开更多

We hypothesized that the GH response to the WAn T would be similar to the GH response to a commonly used pharmacologic provocation test.Methods: Ten children(6 males and 4 females, age range 9.0–14.9 years) participated in the study. Each participant performed 2 tests: a standard all-out WAn T, cycling for 30 s against constant resistance, and a standardized pharmacologic test(clonidine or glucagon). Blood samples for GH were collected before and 10, 30, 45, and 60 min after the beginning of exercise. In addition, we collected pre-and post-exercise blood lactate levels.Results: There was a significant increase in GH levels after the WAn T, yet in 9 of 10 participants, this increase was below the threshold for GH sufficiency. Peak GH after the WAn T was significantly lower compared to the pharmacologic GH provocation tests(with 9 of 10 demonstrating GH-sufficient response).Conclusion: The traditional WAn T cannot be used as a GH provocation test. Further research is needed to develop anaerobic exercise protocols sufficient to promote GH secretion.展开更多
