METHODS: We performed a single-blind, cross-over design study. Twenty-five healthy young men performed three exercise protocols as follows: 1) no blood flow restriction exercise (control group), 2) resistance exercise at 40% of arterial occlusion pressure (AOP) (low group), and 3) resistance exercise at 70% of AOP (high group). Blood lactate, GH, testosterone, and IGF-1 levels were measured at four time points.

RESULTS: There were no differences in the indices before exercise. The blood flow restriction exercise under different pressures had different effects on each index and there was an interactive effect. GH levels were significantly higher in the high group than in the other groups after exercise. Immediately after exercise, IGF-1 and testosterone levels were significantly higher in the high group than in the other groups. At 15 minutes after exercise, testosterone levels were significantly higher in the high group than in the other groups.

METHODS: A total of 48 adolescents with mild to moderate mental disabilities were recruited. The participants were randomly divided into four groups: control group (C), Traditional Chinese Medicine acupuncture group (M), moderate-intensity aerobic exercise group (E) and exercise and acupuncture combined intervention group (J). Before and after the experimental intervention, the participant's height, weight and attention ability were measured.

RESULTS: The improved range of attention total duration of the J group after the intervention was significantly higher than that of the E and M groups (0.05), whereas that of the latter groups was significantly higher compared to that of the C group ( 0.05). The J group showed significantly higher ( 0.05) attention span values after the intervention compared to the E, M and C groups. The C group did not show a significant difference in attention transfer at 12 weeks compared to before intervention (0.05), whereas the E, M and J groups increased significantly ( 0.05) after intervention than the C group.
