Changes in thrust force in swimmers in the annual training cycle

Abstract Study aim : Determination of changes in thrust force and effect size training load swimmers using four swimming strokes monitored 4 times a year. Material methods Five elite male were examined macrocycle 9 months. The times: at baseline (September), immediately after the winter Polish Championships (December), end transition period (March), summer (late May). Results In all participants, significant differences strength (p < 0.001) observed between measurements I II IV 0.001). Athletes specializing 200 m characterized by smaller decline force. breaststroke had significantly higher values than other participants. Conclusions It is suggested that trainers measure during preparatory order to verify applied loads aimed developing strength, as well starting competitor’s level correlation with sports result.
