Skipping is a sportive activity consisting of relative jumping cycles of skipping rope round the body. The main purpose of this study was to establish the relationship between heart rate (HR) and skipping frequency in children, using a regression analysis. A second objective was to determine the intensity corresponding to the lowest heart rate and least energy cost of rope skipping. A Repeated ANOVA design requiring the subjects to perform skipping at three different trials and at five different intensities (Scales) was used. To achieve these objectives, the skipping frequency at which each of the 87 school children aged 12.5 ± 2.5 years felt at ease, was gradually increased according to a five- intensity scales or frequencies (Preferred, -10%, +10%, -20% and +20%), and randomly applied at three minutes interval. HR was determined at rest and during rope skipping using the polar HR monitor. The comfortable skipping frequency was determined following three steps and in three days using the standard procedure. Data were analysed using ANOVA repeated measures and a second degree polynomial regression analysis. The results indicate that there is a comfortable skipping frequency (CSF) corresponding to the lowest HR. This CSF was reached at 116± 2 skips.min-1 in the study group. The subjects that maintained a stable skipping rhythm showed better physiological and mechanical results. The study concludes that the attainment of a CSF leads to lower HR;. rope skipping could therefore be recommended as an inexpensive sportive activity that could be used to develop fitness in children. For a clearer understanding of what happens during this activity it is recommended that maximal oxygen consumption (VO and max) the electro myographic (EMG) activity of the main muscles involved in the activity must be studied to buttress the results of the study.
