Effects of rope skipping type on the energy expenditure and metabolic rate

ABSTRACT

Choi, D.H. Effects of rope skipping type on the energy expenditure and metabolic rate. Exercise Science, 13(1): 25-34, 2004. Rope skipping is known as a very vigorous exercise but effective training for improving aerobic and anaerobic metabolism. This investigation examined the effects of rope skipping type on metabolic rate and sex differences of elementary student. Fifteen male and fifteen female elementary student recruited for rope skipping at 120r/min for 3min. They randomly assigned for alternative and two foot jump skipping trials with one week interval. Metabolic rate(oxygen consumption, HR, RER, Lactate) and energy expenditure(Kcal, MET) variables were measured at resting, after rope skipping and 3min recovery phase. The collected data were statistically analyzed using two-way repeated ANOVA for differences of sex and rope skipping type. Data were interpreted at the .05 level of significance. There was no significantly different on oxygen consumption following 2 kind of rope skipping type. There was a significantly different two foot jump style from alternative rope skipping style which means of RER were .823-.825(p<.007). The means of RER for two foot jump style exceeded 1.0 which indicated that young children were much relying on anaerobic sources. In addition, mean blood lactate was significantly higher in two jump style compare to alternative style for both sexes(p<.000). The present data showed that 4.71-5.25mmole for two jump and 3.82-3.99mmole for alternative style. Therefore, it seems like that alternative rope skipping style is much easier than two foot jump style. In conclusion, we verified that in case of the same rate of rope skipping, alternative rope skipping is the more efficient and comfort methods for elementary students.
