Effects of 12-week free sprint training and speed, agility, and quickness training (SAQT) on reaction time and lower limb muscle activation during crouch start

SAQT effectively enhanced lower limb muscle activation, suggesting benefits for neuromuscular coordination and explosive power development. The lack of improvement in reaction time may be due to participants' limited crouch start proficiency. Integrating SAQT with skill-based start drills may better improve sprint performance. Future studies should examine trained or professional athletes to further validate these findings.
