Effects of High-intensity Interval Training in Combination With Side-alternating Whole-body Vibration

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.

Treatment and study plan

4x4 min HIT

Other

Conventional 4x4 min high-intensity interval training

4x4 min HIT + WBV (18 Hz)

Other

4x4 min high-intensity interval training in combination with whole-body vibration at 18 Hz during the active rest

4x4 min HIT + (30 Hz)

Other

4x4 min high-intensity interval training in combination with whole-body vibration at 30 Hz during the active rest

whole-body vibration at 30 Hz

Other

4x3 min whole-body vibration at 30 Hz

Primary outcomes

  1. Change from baseline in Critical Power

    Time frame: 8 weeks intervention

    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.
