Integrating Specific Training with C4 Supplementation to Enhance Sport-Specific Performance in Futsal Players

Abstract

Background: In futsal, an excessive emphasis on tactical and technical development often leads to the neglect of physiological and biomechanical conditioning. Key biomechanical factors, including acceleration, reaction time, stride length, and step frequency, are critical to performance but are frequently underemphasized in training programs. Objectives: This study examined the effects of six weeks of targeted training, with or without C4 supplementation, on biomechanical variables, explosive power, and SpO2 in Iraqi Premier League futsal players during a fitness maintenance period. Methods: Forty-five players were randomly assigned to three groups (n = 15 each): Experimental Group 1 (training + C4), Experimental Group 2 (training + placebo), and the control group (regular training). Assessments were conducted at baseline and after 3 and 6 weeks. Results: Both experimental groups showed significant improvements in acceleration, reaction time, stride length, explosive power, and SpO2, whereas step frequency remained unchanged. No significant differences were observed between EX1 and EX2, indicating no additional effect of C4 supplementation. Conclusions: The targeted training program effectively improved key biomechanical and physiological parameters in futsal players, underscoring the importance of focused conditioning. Under the tested conditions, C4 supplementation did not confer additional benefits.
