Active Static Stretching (AIS) stretches the muscle with repeated antagonist muscles contraction is suggested able to improve recovery. The aim of this study was to compare AIS and static stretching (SS) as a recovery strategy. A total of 11 male team sport athletes (Age: 20.64±1.86 years old; Weight:65.14±13.41 kg; Height: 171.95±5.70 cm; VO2max: 50.62±4.44 ml/kg/min) were recruited for this crossover-randomised design study. Modified Astrand Treadmill Protocol was used in preliminary testing to determine subjects’ maximal oxygen consumption (VO 2 max) and used to determine muscle damaged protocol intensity. During experimental trials, subjects were required to complete physical [leg power, agility, repeated sprinting ability & active range of motion (AROM)] and perceptual [Total Quality Recovery (TQR) & Visual Analog Pain Scale (VAS)] assessments. A 30-min downhill run at 70% VO 2 max with -12.5% gradient of exercise-induced muscle damage protocol was performed by the subjects. Subjects were required to perform SS (15s) or AIS (2s x10 repetitions) on 5 muscles group: gluteal, quadriceps, hamstring, adductors and gastrocnemius for both legs. All physical and perceptual assessments were conducted at post exercise after 24 hours (POST-24H), 48 hours (POST-48H) and 72 hours ( POST-72H). Significant differences were found only for DH AROM POST-24 (SS: 57.29° vs AIS: 61.50°, p=.048) and NDH AROM POST-48H (SS: 62.29° vs AIS: 67.10°, p=.002). In conclusion, AIS is significantly better in recovery of AROM which indicates recovery of muscle from microtrauma was higher. SS has slight advantage in recovery of leg power (SS: -4.141% vs AIS: -7.156%) and agility (SS: 0.007% vs AIS: 2.513%) at POST-24H. AIS is slightly better in fastest sprinting time (AIS: -1.935% vs SS: 1.613%), MST (AIS: -1.235% vs SS: 1.553%), TQR (AIS: 32.200% vs SS: -47.200%) at POST-24H, VAS (AIS: -34.524% vs SS: -9.673%)at POST-48H and FI( AIS: 72: -18.720% vs SS: 1.302%) at POST-72H.
