Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Branched chain amino acid
Branched chain amino acid as food supplement
Branched chain amino acid
seven graded intakes of a BCAA (branched chain amino acid) mixture from 50 to 350 mg.kg-1.d-1 will be used to measure BCAA requirement
Strength training
Strength training will include a split-training program using all major muscle groups of the body on a three day "on", one day "off" protocol. Muscle areas targeted on each training day will be as follows: Day1: chest, shoulder, triceps; Day2: back, biceps; Day3: legs and calfs; Day4: will be a rest day. On Day5: this cycle will begin again. A combination of free weights and machines will be used for each training day. Progressive overload protocol will be applied where the load used by every participant will be adjusted bi-weekly based on their 70% of 1 repetition maximum (maximum weight that can be lifted only one time). Instruction will be provided for all exercises and professional trainers will oversee all training sessions.
