Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Hydrolyzed collagen and Vitamin C powder mix
20 g hydrolyzed collagen + 50 mg vitamin C (ascorbic acid) pre-packed powder diluted in 250 ml (8 oz) of water
Collagen and Vitamin C powder mix nutritional intervention
20 g collagen + 50 mg vitamin C daily, 60 min prior to exercise
Maximum power training exercise
Explosive/power-based exercise training program 3 times/week at home consisting of drop jumps, box jumps, weighted jump squats loaded in a progressive manner weekly for 3 weeks. At baseline and at the end of each of the 3 weeks, measures of explosive performance are assessed in the lab (maximal isometric squat, counter-movement jump and squat jump)
Maltodextrin powder
20 g maltodextrin pre-packed powder diluted in 250 ml (8 oz) of water
Maltodextrin placebo powder
20 g maltodextrin placebo daily, 60 min prior to exercise
Maximum power training exercise
Explosive/power-based exercise training program 3 times/week at home consisting of drop jumps, box jumps, weighted jump squats loaded in a progressive manner weekly for 3 weeks. At baseline and at the end of each of the 3 weeks, measures of explosive performance are assessed in the lab (maximal isometric squat, counter-movement jump and squat jump)
