Temporal and Spatial Parameters in Interpersonal Coordination of Jumping Rope Elite Boys

Abstract

Background: Coordination depends on online performance, and online feedback supports the successful coordination of individuals in joint implementations. Objective: The purpose of the research was to investigate temporal and spatial parameters in interpersonal coordination. Methods: A single study was applied with 14 jumping rope elite boys (13-18 years). The subjects performed the jumping rope activity for 8 months so that they could do them properly and without online visual feedback. A Vicon motion analysis system with six infrared cameras was used to record three-dimensional movements of the legs and rope whirling. Results:The results of the one-way ANOVA showed that with enough practice, even in the absence of feedback, landing position (spatial parameter) and hand-foot time deviation, timing variation in rope whirling, and landing time (temporal parameter) of joint groups will reach to equal level while a significant difference was observed in jump height (spatial parameter) and movement time (temporal parameter) between individuals (P≤0.05). Conclusion: So, increasing task difficulty, amount and sustainability of inter-personal coordination will increase. according to individual and joint tasks constraints following cases can be occurred: i) increasing joint task demands, ii) increasing amount and sustainability of interpersonal coordination, iii) change in joining individual's power.
