Clinical Trial Summary

The aim of the study is to investigate the acute and short-term effects of collagen peptides (Collagen Peptan) on muscle and connective tissue during an eccentric overload training period. Currently, all studies investigating the effects of post-exercise collagen supplementation did this in the absence of whey proteins, which are part of the standard recommendations for post-exercise recovery. The investigators will therefore investigate whether the combined intake of whey proteins and collagen peptides ensures a better recovery of exercise performance and whether it can prevent or reduce symptoms of muscle and tendon overload during a three-week eccentric overload training period (n = 22).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in countermovement jump performance	Change in jump height when performing a countermovement jump, measured via a force platform	Pretest - 48 hours after the first training session (day 3 of training intervention) - Posttest (day 22 of training intervention)
Primary	Change in maximal isometric knee-extension force of the right leg	Change in maximal isometric knee-extension force (angle = 45°) of the right leg	Pretest - 48 hours after the first training session (day 3 of training intervention) - Posttest (day 22 of training intervention)
Primary	Change in anteroposterior thickness of the right patellar tendon	Change in anteroposterior thickness of the right patellar tendon	Pretest - 48 hours after the first training session (day 3 of training intervention) - Posttest (day 22 of training intervention)
Primary	Change in neovascularization of the right patellar tendon	Neovascularization of the right patellar tendon scored with the Modified Ohberg Score (range 0 - 4; the higher the score, the higher the degree of neovascularization).	Pretest - 48 hours after the first training session (day 3 of training intervention) - Posttest (day 22 of training intervention)
Secondary	Change in pain perception at the muscular level (VAS scale)	Change in pain perception at the muscular level of the right leg, measured via the Visual Analogue Scale (range 0 - 10; the higher the score, the higher the pain level)	Training 1 (day 1 of training intervention) - Training 2 (day 3 of training intervention) - Training 8 (day 9 of training intervention) - Training 17 (day 19 of training intervention) - Posttest (day 22 of training intervention)
Secondary	Change in pain perception of the patellar tendon of the right leg (VISA-P)	Change in pain perception of the patellar tendon of the right leg, measured via the VISA-P questionnaire (range: 0 - 100; the lower the score, the higher the symptoms of patellar tendon overload)	Pretest - Training 1 (day 1 of training intervention) - Training 17 (day 21 of training intervention) - Posttest (day 22 of training intervention)
Secondary	Change in the blood concentration of creatine kinase	Change in blood concentration of creatine kinase (marker of muscle damage)	Pretest - Training 2 (day 3 of training intervention) - Posttest (day 22 of training intervention)
Secondary	Change in the blood concentration of Interleukin 6 (IL-6)	Change in blood concentration of Interleukin 6 (IL-6; marker of inflammation)	Pretest - Training 2 (day 3 of training intervention) - Posttest (day 22 of training intervention)
Secondary	Change in the blood concentration of N-terminal propeptide of type I procollagen (P1NP)	Change in blood concentration of N-terminal propeptide of type I procollagen (P1NP; marker of collagen synthesis)	Pretest - Training 2 (day 3 of training intervention) - Posttest (day 22 of training intervention)
