초록
Our purpose of this study was to deterrnine the most effective cool-down exercise‘ Therecovery times of dynamic strength after isometric and isotonic cool-down exercise weremeasured immediately post cool-down exercise, 30 seconds later and 60 seconds later in30 normal, healthy men from 19 to 29 years, using dumbells(Model, Iron). The recoverytime of dynamic strength had a significant positive correlation with isotonic andisometric cool-down exercise using the Chi-sQuare method (p<0.01). Sources ofsignificant differences were deterrnined by the Wilcoxon signed-ranks test (p<0.01). Theisometric cool-down exercise significantly shortened the recovery time of dynamicstrength. We suggest that the isometric cool-down exercise may be more effective thanisotonic cool-down exercise in shortening the recovery time of dynamic strength.
