EXPERIMENTAL STUDY ON THE IMPACT OF INTERMITTENT STRENGTHENING TRAINING ON ATHLETES

Introduction: High-intensity interval training (HIIT) refers to multiple short-term high-intensity exercises. Objective:To study the impact of sprint interval training (SIT) on the athletic ability of elite rugby players. Method:36 male rugby players from a sports college were selected.They were randomly divided into upper limb training (Group A), lower limb training (Group B), and routine training (Group C - control). Group C received routine training for six weeks. Groups A and B added SIT training based on Group C's upper and lower limb training. Results:After training, the maximum aerobic power (MAP) in Groups A and C was significantly higher (P < 0.05), as well as the myeloperoxidase (MPO) of lower limbs in group B (P < 0.05). After completing 5 and 6 sets of SIT training, blood lactic acid (BLA) was lower in group B (P <0.05). Parameters such as upper limb intermittent sprint exercise capacity and lower-limb aerobic exercise capacity did not significantly change compared with the same parameters before training (P>0.05). Conclusions: Excellent male rugby players can improve their upper limb aerobic and lower limb intermittent sprint athletic ability by integrating different methods of SIT training into their daily training.
