New research studying elite handball players discovered a breakthrough method for predicting delayed-onset muscle soreness (DOMS) using heart rate variability monitoring during exercise. This groundbreaking study reveals how specific heart rhythm patterns around a critical 120 BPM threshold can forecast muscle damage before pain develops. Learn how this HRV research could revolutionize injury prevention and training optimization for athletes and coaches.
