Brief Summary

This randomized controlled trial evaluated the effects of an 8-week combined strength and plyometric training program on lower-limb performance and neuromuscular function in male Sanda athletes. Thirty male Sanda athletes were randomly assigned to a strength training group or a combined strength and plyometric training group. Both groups trained three times per week for 8 weeks. Outcomes were assessed before and after the intervention and included standing long jump, countermovement jump, hexagon test, reactive strength index, lower-limb vertical stiffness, and lead-leg Sanda roundhouse kick attack time.

Outcome Measures

Primary Outcomes (5)

• Change in Standing Long Jump Performance

  Standing long jump distance was assessed using standardized procedures. Participants completed three maximal trials, and the best distance in centimeters was recorded.

  Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks

• Change in Countermovement Jump Height

  Countermovement jump height was assessed using a force platform. Participants completed three trials with hands on hips, and jump height was derived from the equipment.

  Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks

• Change in Hexagon Test Performance

  Change-of-direction performance was evaluated using the hexagon test. Participants completed three timed trials, and the fastest time in seconds was retained.

  Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks

• Change in Reactive Strength Index

  Reactive strength index was derived from force-platform data during repeated bilateral maximal vertical hops.

  Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks

• Change in Lower-Limb Vertical Stiffness

  Lower-limb vertical stiffness was calculated from force-platform data during repeated hopping trials using peak ground reaction force, center-of-mass vertical displacement, body mass, contact time, and gravitational acceleration.

  Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks

Secondary Outcomes (1)

• Change in Lead-Leg Sanda Roundhouse Kick Attack Time

  Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks

Strength Training

ACTIVE COMPARATOR

Behavioral: Strength Training

Combined Strength and Plyometric Training

EXPERIMENTAL

Behavioral: Combined Strength and Plyometric Training

Interventions

Strength Training BEHAVIORAL

The strength training intervention consisted of periodized resistance training over 8 weeks, with progressive increases in intensity based on one-repetition maximum. Exercises included lower-limb resistance exercises such as squat, deadlift, and lunge variations.

Strength Training

Combined Strength and Plyometric Training BEHAVIORAL

The combined training intervention consisted of the same periodized strength training program as the strength training group plus a plyometric training component. Plyometric exercises were performed on non-slip rubber flooring, and jump height was monitored before each session.
