ABSTRACT
In this study, energy consumption of three types of basic rope skipping was measured, together with an investigation of work intensities. The subjects were 5 healthy adult male. The results of this study were as follows :<BR>1) The average relative metabolic rate (RMR) of 1 skip (one skip to one forwardturn of rope), 2 skip (double skip to one forward-turn of rope) and running skip were 13.6, 11.7 and 10.3, respectively, and it was noted that work intensities decrease in order of 1 skip, 2 skp and running skip.<BR>2) On the three types of five minute rope skipping, the oxygen intake for the last one minute of exercise of 1 skip was equivalent to 63.7-78.0% of maximal oxygen intake, and in cases of 2 skip and running skip were 57.5-76.3% and 56.8-67.2%, respectively.<BR>3) When skip frequencies of 1 skip were 92, 120 and 156 skips/min, respectively, oxy-gen requirement for 120 skips/min was the lowest, therefore, it was noted that skip fre-quency of 120 skips/min was optimal.
