Objectives: To determine the effects of whole-body vibration (WBV) training on depression, anxiety, stress, and quality of life (QoL) in college students. Methods: The participants comprised college students who led physically inactive lifestyles as revealed by their Medical Outcomes Study Form 36 (SF-36) scores, and with elevated scores of Depression Anxiety Stress Scale (DASS) test. They were randomly allocated to two groups of 15 each: (a) the WBV group (male = 3, female = 12) and (b) the exercise group (male = 6, female = 9). The participants in the WBV group performed prescribed exercises while they stood on a vibrating platform whereas those in the exercise group performed the same exercises but without the vibrating platform. After four weeks of twice-a-week training, DASS and SF-36 were measured. The pre- and post-scores were compared between the groups. Results: Depression (p < 0.001), anxiety (p < 0.001), and stress (p < 0.001) were found to reduce significantly for the WBV group compared to the exercise group. There was also significant within-group improvement in all the components of SF-36 (p < 0.040). Conclusions: Exercising on the WBV platform may reduce depression, anxiety, and stress in college students and improve their overall QoL.
Objective: The purpose of this study was to compare the effects of a complex versus a contrast training regimen with steroid hormones and the performance of soccer players. Methods: Thirty-six professional male soccer players were randomly divided into 3 equal groups: complex training (n = 12; body mass index [BMI], 22.95 ± 1.76 kg/m 2 ), contrast training (n = 12; BMI, 22.05 ± 2.03 kg/m 2 ), and control (n = 12; BMI, 22.27 ± 1.44 kg/m 2 ). Players from the complex and contrast groups were trained for 6 weeks (3 d/wk). The complex group performed 4 different exercises, each composed of strength (80% of 1 repetition maximum [RM]) and power components alternately. The contrast group performed the same strengthening exercises alternately at different intensities (40% and 80% of 1 RM). All players were tested for free testosterone, cortisol, vertical jump, 20-m sprint, and agility T-test at the baseline and after 6 weeks of training. Results: A 3 × 2 mixed analysis of variance revealed a significant difference in time effect (P ≤ .05), whereas a nonsignificant difference was found in the group effect for all outcome variables. group × time interaction was significant in all the variables (P b .01) except cortisol (P = .28).
Conclusion:Complex training showed greater improvement in physical performance and free testosterone concentration compared with contrast training, whereas both types of training decreased cortisol concentration in a similar fashion. (
