Investigation of the training effects following 8 weeks of high-intensity interval training (HIT)in combination with side-alternating whole-body vibration compared to conventional HIT or side-alternating whole-body vibration. The adaptations are investigated on a molecular (muscle biopsy of the M. vastus lateralis) and systemic (e.g. cycling, jumping mechanography, dynamometry) level. In addition, the acute effects of the first and last training session will be investigated on a molecular (e.g. satellite cell activation, mRNA abundance) and systemic (e.g. ventilatory ga exchange, heart rate, rating of perceived exertion) level.

Change from baseline in Critical Power
The differences in changes in Critical Power \[Watts\] are compared between the 4 training groups. For this purpose, participants complete before and after the training intervention an incremental cycling ramp test and 4 cycling constant-load tests.
Time frame: 8 weeks intervention
