TL;DR: Optimal grip span was identified for both genders and hand size and optimal grip span correlated in women but not in men, which means when measuring handgrip strength in women, hand size must be taken into consideration.

TL;DR: Whether physical activity, sedentary activities, and/or cardiorespiratory fitness are related to waist circumference in adolescents, as previously reported in adults, is investigated.

TL;DR: No relationship was found between the level of physical activity and lipid‐metabolic index in either sex, but there was an inverse relationship between the lipid‐ Metabolic index and aerobic capacity in males and females, and in females, a favorable lipid‐ metabolic index was associated with greater muscle strength.

TL;DR: Both aerobic fitness and weight management are associated with a composite index of blood lipids and glycaemia in adolescents, a new tool which should be adopted by schools as "aerobic fitness standards".

TL;DR: There is a shortage of scientific evidence concerning the adverse effects following creatine supplementation in healthy individuals even with long-term dosage, so creatine may be considered as a widespread, effective and safe ergogenic aid.
