Muscles groups participation in crawl stroke during a recovery phase

1. ABSTRACT AND KEY WORDS Thema: Using EMG for comparing correct technic of upper limb recovery phase in the front crawl. Introduction: Our measurement is aimed to detect influence of muscles activity of the shoulder joint and back during the upper limb recovery phase in the front crawl. Monitoring and recording muscles activity by EMG inform about movement stereotype of our probands. We've tried to localized uncorrect activation oppossite to optima! muscle activity of (ex) competitive swimmer. Results of measuremens are used for correction of faulty upper limb recovery stereotype. Results should enlarged knowledge about technic of recovery and help in way of teaching both competitive and noncompetive swimmers, like students of FTVS UK (Fakulty of phyzical education and sport at The Charles University in Prague), which learns to swim in the age of adulthood. Protocol and measurements: Muscles were selected acording recommendation of leader of my diploma dissertation Mgr. Daniel Jurák. The ]ocations of the electrodes on the body were chosen acording to the recommendation of MUDr. David Pánek. Groups of muscles round shoulder joint were measured using EMG during the upper limb recovery phase in the front crawl. The EMG is synchronized with videorecorder. Both videorecord and EMG rneasurernent were analysed by..
