Methods-The study was conducted on six national male badminton players. Maximum oxygen consumption (Vo,), ventilation (VE), heart rate, and respiratory quotient were measured by a protocol of graded treadmill exercise. Twelve training sessions and 35 singles matches were analysed. Heart rate and blood lactate were monitored during technical training routines and match play. Fasting blood samples collected on two occasions-that is, during off season and 12 hours after specific training-were analysed for serum urea, uric acid, and CPK. Results-Analysis of the on court training regimens showed lactate values of 8-10.5 mmol/l in different phases. The percentage of maximum heart rate ranged from 82% to 100%. Urea, uric acid, and CPK activity showed significant changes from (mean (SD)) 4.93 (0.75) mmo/lI to 5.49 (0.84) mmol/l, 0.23 (0.04) to 0.33 (0.06) mmol/l, and 312 (211.8) to 363 (216.4) IU/l respectively. Conclusion-Maximum lactate reported in the literature ranges from 3-6 mmoI/l. Comparatively high lactate values and high percentage of maximum heart rate found in on court training show a considerable stress on muscular and cardiovascular system. The training load needs appropriate monitoring to avoid overtraining. Workouts that are too intensive may interfere with coordination, a factor that is important in sports requiring highly technical skill such as badminton. (BrJ7 Sports Med 1997;31:342-345
