![]() ![]() ![]() A deeper insight into the specificity of fatigue and recovery patterns of younger and older athletes during the days after an intensive bout of exercise is of practical interest for an appropriate training prescription. Master athletes experience either greater muscle damage, slower repair, or a combination of both effects, which can be attributed to physiological and social lifestyle changes beginning in the fourth decade of life effects ( Smith and Norris, 2002 Fell and Williams, 2008). It has been discussed that recovery processes during the days after intensive physical exercise are modified in elderly athletes (master athletes) compared to the age of peak performance ( Fell and Williams, 2008). Furthermore, the results indicate that MMR after resistance exercise does not contribute to a faster recovery of physical performance, neuromuscular function, or muscle damage, but promotes recovery of perceptual measures regardless of age. In conclusion, master athletes neither reach higher fatigue levels nor recover more slowly than the younger athletes. In three participants (two young and one master athlete), the individual results revealed a consistently positive response to MMR. A significant two-way interaction between recovery strategy and time of measurement was found for MS and PPC ( p<0.05 faster recovery after MMR). Age-related differences were found for BLa, MS, and PPC (higher post-exercise fatigue in younger athletes). A three-way mixed ANOVA revealed a significant time effect of the squat protocol on markers of fatigue and recovery ( p<0.05 decreased MVIC, CMJ, twitch force, and PPC increased CK and MS). Furthermore, maximal voluntary isometric contraction (MVIC) force, countermovement jump (CMJ) height, resting twitch force of the knee extensors, serum concentration of creatine kinase (CK), muscle soreness (MS), and perceived physical performance capability (PPC) were determined before and after training as well as after 24, 48, and 72h of recovery. Internal training loads were recorded during and after squat sessions. Training sessions were followed by either MMR or passive recovery (PR). Sixteen healthy and resistance-trained young (age, 22.1☒.1years N=8) and master male athletes (age, 52.4☓.5years N=8), who had a similar half squat 1-repetition maximum relative to body weight, completed two identical squat exercise training sessions, separated by a 2-week washout period. The aim of this study was to investigate whether recovery from eccentric squat exercise varies depending on age and to assess whether the use of a mixed-method recovery (MMR) consisting of cold water immersion and compression tights benefits recovery. 7IST University of Applied Sciences, Düsseldorf, Germany.6Contilia Heart and Vascular Center, Elisabeth-Hospital, Essen, Germany.5Faculty of Medicine, Ruhr University Bochum, Bochum, Germany.4Institute of Sports Science, Johannes-Gutenberg University, Mainz, Germany.3Institue of Sports and Preventive Medicine, Saarland University, Saarbrücken, Germany.2School of Human Movement and Nutrition Sciences, The University of Queensland, Brisbane, QLD, Australia.1Faculty of Sport Science, Ruhr University Bochum, Bochum, Germany.Julian Schmidt 1, Alexander Ferrauti 1, Michael Kellmann 1,2, Florian Beaudouin 3, Mark Pfeiffer 4, Nicola Reiner Volk 1, Jan Martin Wambach 5,6, Oliver Bruder 5,6 and Thimo Wiewelhove 7 *
