Aktiv komparator: 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
|
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.

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.
|

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.

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.
|

|
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.

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.
