Combined Strength and Plyometric Training in Sanda Athletes

25. mai 2026 oppdatert av: Mingjie Hu

Effects of Combined Strength and Plyometric Training on Lower-Limb Performance and Neuromuscular Function in Sanda Athletes: A Randomized Controlled Trial

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.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: Strength Training
Atferdsmessig: Strength Training
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.
Eksperimentell: Combined Strength and Plyometric Training
Atferdsmessig: Combined Strength and Plyometric Training
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.

Tiltaksbeskrivelse
Tidsramme
Change in Standing Long Jump Performance
Tidsramme: Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
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
Tidsramme: Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
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
Tidsramme: Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
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
Tidsramme: Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
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
Tidsramme: Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
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

Tidsramme
Change in Lead-Leg Sanda Roundhouse Kick Attack Time
Tidsramme: Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
Lead-leg Sanda roundhouse kick attack time was assessed as a sport-specific outcome using high-speed video recording. Attack time was defined as the interval from movement onset to first target contact, and the mean of three valid trials was used for analysis.
Baseline and post-intervention within 48 hours after the final training session, approximately 8 weeks
