Short vs. Long Bouts of All-Out Rope Skipping: Effects on Metabolic and Perceptual Responses

Abstract

Rope skipping has been well documented for eliciting positive effects on various health outcomes and contributing to overall physical activity levels. However, the specific health benefits may depend on the duration and intensity of the exercise bouts. This study aimed to compare the (1) metabolic and (2) perceptual responses between short (30 s) and long (3 min) bouts of all-out rope skipping, and to (3) evaluate the reliability and validity of a newly invented electronic rope (E-rope). A total of 23 young adults (13 males and 10 females; aged 23.23 ± 2.62 y) repeated short and long skipping bouts on two testing days. The oxygen consumption (V·O2), peak respiratory exchange ratio (RER), heart rate (HR), rate of perceived exertion (RPE), and post-exercise muscle soreness were assessed during each trial. Longer skipping bouts (148.33 skips·min−1) resulted in significantly greater metabolic responses (p < 0.01, d = 1.00–3.27), higher rates of perceived exertion (p < 0.01, d = 2.28), and more post-exercise muscle soreness (p < 0.01, d = 0.66–1.49) compared to shorter bouts (165.83 skips·min−1). The E-rope demonstrated sufficient concurrent validity (r > 0.9) and between-day reliability (ICC3,1 = 0.89–0.95) but slightly overestimated the number of skips. Both long and short all-out skipping bouts were considered moderate-to-vigorous exercise, but longer bouts resulted in higher metabolic and perceptual demands. These findings may be useful for practitioners to strategically apply different skipping bouts to improve physical activity levels and facilitate training adaptation. The E-rope could serve as a self-monitoring and self-evaluating tool.
