Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: A randomized, cross-over, repeated measures design is used to evaluate the effects of DO on recovery. At random in study phase I the half of the group performs a DO self-treatment twice daily (4 applications) for 15 minutes each, whereas the other half gets no intervention. After a washing out period in study phase II a crossover will be performed. The same protocol is performed again, whereas the other half of the participants carries out the DO intervention .

Brief summary: The purpose of this study is to evaluate the effects of Deep Oscillation (DO) self-treatment on recovery after fatiguing soccer training. We investigate deep oscillation (DO) self treatment as a measure to promote regeneration, hypothesizing that DO leads to an accelerated recovery within the first 48h after fatiguing training with positive effect on the maximum strength, rated perceived exertion, creatinkinase (CK) values and DOMS compared to no treatment after an .

Detailed description: Recovery time between in association football (soccer) often is not long enough to completely restore. Insufficient recovery can result in a reduced performance and suboptimal development in the training process and a higher risk for injuries. The purpose of this study is to evaluate the effects of Deep Oscillation (DO) self-treatment on recovery after fatiguing soccer training. Deep Oscillation is a unique method which is characterized by an alternating electrostatic which results in a deep resonance vibration of patients tissue.

Methods: In a randomized crossover study design including 10 soccer players of the 5th german devision the following parameters will be evaluated directly before and 48h after an fatiguing soccer specific exercise: Maximum isokinetic strength of the leg and hip extensors and flexors (Con-Trex® Leg Press, Physiomed, Germany), rating of perceived exertion (RPE) during isokinetic testing (Borg scale 6-20) and creatine kinase (CK) serum levels. Delayed Onset Muscle Soreness (DOMS; visual analogue scale 1-10) will be recorded 24 and 48h post-exercise. At random half of the group will perform a DO self-treatment twice daily (4 applications) for 15 minutes each, whereas the other half gets no intervention. 4 weeks later in a cross-over design the same procedure will be conducted again.
