High endurance capacity, expressed by VO2max, is essential for optimal performance and is influenced by anthropometric and physiological parameters. 30 Indian young national level field-hockey players were studied to evaluate their endurance capacity and associated parameters. VO2max, relative physical work capacity at 170 bpm (rPWC), heart rate recovery (HRR3/6 at 3rd/6th minute), hemoglobin concentration (Hb), resting heart rate (rHR) and blood pressure (rBP), maximum heart rate (HRmax), basal metabolic rate (BMR), demographic and anthropometric parameters were measured and analyzed.
