Design outcomes

Primary

MeasureTime frame
Maximal strength measured as kilograms lifted in 1 repetition maximum (1-RM) tests in leg press, lat pulldown and bench press at baseline and after the 12-week intervention

Secondary

MeasureTime frame
1. Muscle mass measured in kilograms using bioelectrical impedance (Tanita MC780 multi-frequency segmental body composition analyzer) at baseline and after the 12-week intervention 2. Jump height measured in centimeters performing a countermovement jump on a force platform at baseline and after the 12-week intervention 3. Power output in the bench press measured in watts lifting a 15 kg barbell, calculated using a linear encoder measuring velocity and a commercial software program (MuscleLab Software v8.13, Ergotest Technology AS, Langesund, Norway) at baseline and after the 12-week intervention
