AbstractRope skipping is a fun and excellent moderate to vigorous physical activity (MVPA) for school students especially for elementary and junior high schools. Studies demonstrate that prolonged rope skipping exercise could effectively improve aerobic fitness. Considering the specificity principle in fitness evaluation, it is desirable to develop a rope-skipping specific exercise testing for evaluating aerobic fitness.
PURPOSE The purpose of this study was to develop a prediction model to estimate peak oxygen uptake (VO2peak) from a sub-maximal cadence rope skipping test among secondary school students.
METHODS A total of 58 secondary school students (38 boys, 20 girls, age=13.8+/-1.1 yrs) completed two different forms of rope-skipping exercises (free-style skipping & Gallop-style skipping, in randomized order) with a steady cadence of 60 skips per min, for 3 min each and at least 20 min apart. Exercise heart rates (EHR) throughout the 3-min skipping and additional 1-min post-exercise HR (PHR) were monitored continuously using Polar HR monitor. Students also completed a treadmill VO2peak test using calibrated direct VO2 metabolic measuring system (COSMED K4b2). Moderate to vigorous physical activity habits (MVPA), in term of average min per day were assessed by questionnaire. VO2peak was then correlated with HER and PHR at various time points, as well as MVPA, BMI, age, and gender, using stepwise regression, to determine criterion-related validity.
RESULTS Regardless of skipping style, VO2peak was best correlated with PHR at 20s after the exercise, followed by MVPA, gender, and BMI. The best equation was: VO2peak = 70.422 + (7.542* gender) + (.126*MVPA) - (.470*BMI) - (.167 *PHR@20s); R = .870, SEE = 4.54 ml·kg-1·min-1, using the free-style rope skipping test. Both free-style and Gallop-style rope skippinggave similar level of criterion-related validity.
CONCLUSION A 3-min free-style cadence rope skipping submaximal test was effective to estimate VO2peak of secondary school students using post-exercise heart rate at 20 seconds after the exercise, and gender, MVPA, and BMI. This test is particularly suitable for athletes of rope skipping to evaluate aerobic fitness due to its’ good validity and specificity.
