Most sports individuals or athletes including tennis players perform stretching during warm-up prior to physical activity in order to prevent injuries and enhance sports performance by improving flexibility. Traditionally static stretching exercises have been a prominent feature of warm up routines. On the other hand, dynamic stretching improves knee joint position sense, increases oxygen uptake and lowers lactate concentration. Hamstring and calf muscle group play a significant role in agility function in tennis players. So the study is conducted to check the effect of static and dynamic stretching of hamstring and calf muscle on agility performance in tennis players.
