Combined Strength and Plyometric Training in Sanda Athletes

25. maj 2026 opdateret af: 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.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: Strength Training
Adfærdsmæssigt: 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.
Eksperimentel: Combined Strength and Plyometric Training
Adfærdsmæssigt: 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.

Resultatmål
Foranstaltningsbeskrivelse
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.
