Comparison of Oxygen Uptake between Single and Double Legs Rope Jumping Exercise

Abstract

PURPOSE: To investigate differences in oxygen uptake (VO2) between single leg (SL) and double legs (DL) rope jump. METHODS: Nine healthy males, age ranged between 19 and 21 years, (Meanage, Meanweight and Meanheight of 20.22 ± 0.66 yr, 65.11 ± 9.19 kg and 174.22 ± 4.38 cm, respectively). All participants were performed jump rope exercises either a SL or DL jump conditions at the intensity of 72 round/min for 5 minutes. The order of each jump rope condition was randomly assigned. Participants were allowed to have a 15-min rest between each condition. Prior to the testing, anthropometric data including body weight (BW), height, BMI resting heart rate (RHR) were collected. Cardiorespiratory fitness measurement volume of carbondioxide (VCO2) and volume of oxygen uptake (VO2) were collected during exercises. Dependent t-tests were employed to determine differences between the two conditions. RESULTS: SL had lower VO2 (1,970.22 ± 304.12 ml/min) as compared to DL (2,150.78±403.69 ml/min) (p = 0.003). The VO2/BW of SL (30.28 ± 2.75 ml/min/kg) was also lower than DL (33.02 ± 4.65ml/min/kg) (p = 0.021). Although no statistical significant differences were found, the VCO2 of DL (2,453.33 ± 584.18 ml/min) was higher than SL (2,199.44 ± 314.19 ml/min) (p = 0.073). CONCLUSIONS: Oxygen uptake of DL rope jump had higher than SL rope jump in 5 min.
