Effects of moderate-intensity aerobic exercise combined with acupuncture on attention function of mentally-retarded adolescents: a randomised controlled trial.

Objective: To detect the impact of moderate-intensity aerobic exercise combined with acupuncture on the attention function of mentally-retarded adolescents from the three dimensions of attention concentration, attention transfer and attention span.

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).

Effects of a blood flow restriction exercise under different pressures on testosterone, growth hormone, and insulin-like growth factor levels.

Objective: To investigate the changes in serum growth hormone (GH), testosterone, and insulin-like growth factor 1 (IGF-1) during low-intensity resistance exercise under different cuff pressures.

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).
