Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	HIIT + protein	8-week supervised exercise program consisting of high-intensity interval training (HIIT). HIIT: 10x1 min at 85-95% HRmax divided by low intensity recovery periods. Three exercise sessions per week. Participants receive 40 g of a commercially available protein supplement administered as a shake after every exercise session.
DIETARY_SUPPLEMENT	HIIT + placebo	8-week supervised exercise program consisting of high-intensity interval training (HIIT). HIIT: 10x1 min at 85-95% HRmax divided by low intensity recovery periods. Three exercise sessions per week. Participants receive 40 g of a commercially available iso-caloric placebo (Maltodextrin) administered as a shake after every exercise session.
DIETARY_SUPPLEMENT	HIIT and resistance training + protein	8-week supervised exercise program consisting of high-intensity interval training (HIIT) and resistance training (RST). HIIT: 5x1 min at 85-95% HRmax divided by low intensity recovery periods. RST: 3-set resistance training using weight machines to train all major muscle groups with an individual intensity corresponding to 70-80% of one repetition maximum. Two exercise sessions per week. Participants receive 40 g of a commercially available protein supplement administered as a shake after every exercise session.
DIETARY_SUPPLEMENT	HIIT and resistance training + placebo	8-week supervised exercise program consisting of high-intensity interval training (HIIT) and resistance training (RST).

RST: 3-set resistance training using weight machines to train all major muscle groups with an individual intensity corresponding to 70-80% of one repetition maximum. Two exercise sessions per week. Participants receive 40 g of a commercially available iso-caloric placebo (Maltodextrin) administered as a shake after every exercise session.
