Effect of deep oscillation as a recovery method after fatiguing soccer training: A randomized cross-over study

Abstract

Background/ObjectiveIn soccer the recovery time between matches is often not long enough for complete restoration. Insufficient recovery can result in reduced performance and a higher risk of injuries. The purpose of this study was to evaluate the potential of Deep Oscillation (DO) as a recovery method.MethodsIn a randomized crossover study including 8 male soccer players (22 ± 3.3 years) the following parameters were evaluated directly before and 48 h after a 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), creatine kinase (CK) serum levels and Delayed Onset Muscle Soreness (DOMS; visual analogue scale 1–10). By random allocation, half of the group performed a DO self-treatment twice daily (4 applications of 15min each), whilst the other half received no intervention. 4 weeks later a cross-over was conducted. Two-way repeated measures analysis of variance was used to compare treatment versus control.ResultsA significant treatment effect was observed for maximum leg flexion strength (p = 0.03; DO: 125 ± 206 N vs. CG: −115 ± 194; p = 0.03) and for RPE (DO: −0.13 ± 0.64; vs. CG: +1.13 ± 1.36; p = 0.03). There was a trend to better recovery for maximum leg extension strength (DO: −31 ± 165 N vs. CG: −138 ± 212; p = 0.028), CK values (DO: 72 ± 331 U/ml vs. CG: 535 ± 797 U/ml; p = 0.15) and DOMS (DO: 3.4 ± 1.5 vs. CG: 4.1 ± 2.6; p = 0.49).ConclusionIn the present study we found significant effects of DO on maximum leg flexion strength and perceived rate of exertion. Other variables showed a consistent trend in favour of DO compared with the control without significance. DO seems to be a promising method to accelerate the time-course of peripheral recovery of muscle which should be addressed in larger studies in future.Trial registrationClinicalTrials.gov; NCT03411278, 18.01.2018 (during the study).

Application of deep oscillation therapy in the treatment of peripheral arterial diseases

“…One possible way that DO therapy may have impacted PAD symptoms is by improving microcirculation in the affected tissues. By using a lowfrequency deep oscillation technique, DO therapy was shown [36,37,38] to promote lymphatic and blood flow and perfusion, modulate inflammatory processes, reduce oedema and promote tissue regeneration. This could potentially improve tissue oxygenation and nutrient delivery, which helped to alleviate some of the symptoms associated with PAD [39,40].…”

Progressive decrease in leg-power performance during a fatiguing badminton field test

“…A primary difficulty of this type of research is the creation of opportunities to study fatigue under conditions that are reproducible and effective across a range of participants. While there are numerous laboratory-based tests of force generation and fatigue8,9,10,11,12 ) , they are sometimes seen to be lacking in content, face or ecological validity. It is very important that sport-specific movement patterns and speeds are used because, without such activities, the fatigue that has been induced is unlikely to reflect the fatigue that is encountered during an actual competition.…”
