Participants will perform three endurance training sessions weekly for 12 weeks. All participants will be randomly assigned to the protein supplementation group or the placebo (iso-caloric carbohydrate) group. During the 12 weeks endurance training program participants allocated to the protein group (30 g protein per beverage) will receive a protein drink after exercise and prior to sleep at night on training days. On non-training days participants will only receive a protein drink before sleep. Participants allocated to the carbohydrate group (30 g carbohydrates) will receive a carbohydrate drink instead of a protein drink.
In the proposed study, the effects of protein supplementation after training and before sleep on VO2max and performance will be assessed during 12 weeks endurance exercise training in untrained healthy young men. The ready to drink carbohydrate beverage consists of 30g carbohydrate or 30g protein. Previous studies show that the supplementation of 30g protein is in the optimal range to stimulate the muscle protein synthetic response following resistance type exercise. The protein supplementation group in the present study will be compared with an iso-caloric carbohydrate group. In addition, to the pre- and post-intervention biopsies 1 additional muscle biopsies will be taken (in week 6) during the 12 week intervention period. This will create a unique opportunity to establish the timeline of the skeletal muscle adaptive response at functional and mechanistic level following prolonged endurance exercise training, including potential differences between both groups.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Ran from Aug 2017 to primary completion in May 2018, 9 months.
Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 9 months is below that.
Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.
