Brief Summary

This randomized controlled trial aims to assess the effectiveness of a 12-week plyometric training regimen on improving power, speed, and agility among boys aged 10 to 18 years who are actively engaged in sports and exhibit differing levels of biological maturity. The study seeks to determine how maturation affects the responsiveness to the training program, potentially influencing future sports training approaches for young athletes.

Conditions

Athletic Performance; Muscle Fatigue; Plyometric Exercise

Outcome Measures

Primary Outcomes (3)

• Vertical jump height

  The vertical jump is performed on AMTI OR6-7-1000 force platform (Advanced Mechanical Technology, Watertown, USA). Participants stand on the force platform in an upright position and on command, perform a maximum height jump with a countermovement and use of arms. Participants perform three attempts, with a 1-min rest between each. The best attempt is evaluated.

  12 weeks

• Broad jump distance

  The distance in the broad jump is measured with a tape. Participants stand on a pre-marked line with legs approximately shoulder-width apart. From standing, they jump as far forward as possible using a countermovement and land on both feet. The landing spot closest to the starting line is considered for scoring. Participants perform two attempts, with the better attempt being recorded. There is a 1-min rest between attempts.

  12 weeks

• Unilateral triple jump length

  The length of the unilateral triple jump test is measured with a tape. Participants start on one leg on a pre-marked line. Then using a countermovement from knee flexion, they perform a triple jump with the dominant and subsequently the non-dominant lower limb. After the final jump, they must land on both limbs and maintain their position at the landing spot for at least 2 seconds.

Study Arms (2)

Plyometric training

EXPERIMENTAL

Plyometric training program for 12 weeks.

Other: Plyometric training

Control training

ACTIVE COMPARATOR

Regular training program for 12 weeks.

Other: Control training

Interventions

Plyometric training OTHER

Participants undergo a plyometric training program. The plyometric training consists of exercises in the horizontal, lateral, and vertical directions of movement. Exercises are progressively focused on maximal performance with short ground contact (\<250 ms). The training sessions are twice per week.

Plyometric training

Control training OTHER

Participants continues their regular sports activities without additional plyometric training. The training sessions are twice per week.

Control training
