The Ability to Repeat Maximum Speeds and Their Impact on Some Functional and Skill Indicators for Futsal Players

Abstract

The research problem addresses the lack of performance assessments tailored specifically for futsal players, which accurately represent the key physical attributes demanded during matches, alongside insufficient comprehension of their physiological impacts, particularly concerning the cardiovascular and respiratory systems. Consequently, this study aims to offer a detailed descriptive analysis of the physical and physiological performance of futsal players, with a particular emphasis on Repeated Sprint Ability (RSA) and its influence on selected physiological and skill-related variables. The researchers propose that a relationship exists between RSA and certain physiological and technical indicators in futsal players. The experimental procedures involved a sample drawn from players at Al-Saniya Sports Club during the 2024–2025 futsal season. All measurements were performed at the College of Physical Education and Sports Sciences, University of Al-Qadisiyah. Physiological function variables were assessed using the COSMED K5 device, manufactured in Italy. Among the principal outcomes, the capacity to perform repeated high-intensity sprints demonstrated a positive impact on the physiological variables studied (VE, RQ, VE/VO2, VE/VCO2, HR), as well as on multiple composite skill indicators in futsal players. Based on these results, it is recommended that routine physiological assessments be integrated into futsal training programmes to monitor fitness status, and that RSA be systematically incorporated within training regimens.
