Brief Summary:

Overtraining is a real problem for (semi-)professional athletes. Overtraining is often caused by the bodies' lack of ability to recover between training. In addition, during high intensity training reactive oxygen species are formed up to 20 fold compared to resting values. This causes increased muscle tissue damage after intense exercise, which slows down recovery. Improving recovery may increase an athlete's ability to reach higher training volumes resulting in establishing a higher performance plateau.

It is known that hydrolyzed proteins have a positive effect on muscle protein synthesis due to its faster absorption rate. Therefore, it is hypothesized that a known protein hydrolysate may have positive effects on strength recovery.

Primary Outcome Measures :
  1. Muscle strength recovery [ Time Frame: 4 weeks ]
    difference in peak force between the exhaustion challenge and the recovery challenge, measured with a linear encoder during a squat exercise

  1. Blood lactate buildup [ Time Frame: 4 weeks ]
    in mmol/L, measured trough a finger prick after exhaustion and recovery challenge

  2. Body composition [ Time Frame: 4 weeks ]
    fat percentage, based on 4-point skin fold measurement

  3. Exercise volume [ Time Frame: 4 weeks ]
    amount of repetitions x time taken x power, measured with a linear encoder during squat exercise

  4. Peak force output [ Time Frame: 4 weeks ]
    measured with a linear encoder during the squat exercise
