This study investigates the potential benefits of Pulsed Electromagnetic Field (PEMF) therapy for recovery following a fatiguing exercise protocol in recreational athletes. Despite growing interest in PEMF therapy for athletic recovery, few studies have evaluated its effects across a wide range of performance and recovery measures, particularly among recreationally active individuals. This study is the first-ever investigation to examine the effects of PEMF therapy on recovery from fatiguing exercise across multiple performance outcomes, including maximal strength, power, vertical jump height, and muscle soreness, in a sample of recreationally active college-aged individuals. Thirty participants (mean age: 23.7 ± 3.7 years; 19 males, 11 females) were randomly assigned to one of three recovery conditions: PEMF therapy (n=10), placebo (n=10), or control (n=10). The fatigue protocol used in this study was the Yo-Yo Intermittent Recovery Test Level 1 (YYIRT1), designed to induce neuromuscular fatigue. Recovery was assessed through quantitative measures of performance (peak power, peak cadence, vertical jump, and isometric strength) and qualitative measures of muscle soreness. No statistically significant differences were observed between the recovery groups in terms of performance outcomes. However, PEMF therapy did show trends toward improved recovery, particularly in peak power at 24-, 48-, and 72-hours post-exercise, and was the only group to show consistent reductions in muscle soreness. These findings underscore the need for further research in this area and suggest that PEMF therapy may offer marginal recovery benefits, particularly for perceived recovery and power restoration. This study addresses a crucial gap in the scientific literature by providing empirical evidence on the efficacy of PEMF therapy for recreational athletes, suggesting potential applications in non-elite athletic populations, though further research is required to confirm its mechanisms and long-term effects.
