Outcome Measures

Primary Outcomes (7)

• Change in 30 m sprint time

  Sprint performance was assessed using the 30 m sprint test. Time was recorded in seconds using photocell timing gates. Lower values indicate better sprint performance.

  Baseline and immediately after the 8-week intervention

• Change in vertical jump height

  Vertical jump performance was assessed using the My Jump 2 application. Jump height was recorded in centimetres. Higher values indicate better jump performance.

  Baseline and immediately after the 8-week intervention

• Change in 505 agility test time

  Change-of-direction performance was assessed using the 505 agility test. Time was recorded in seconds. Lower values indicate better agility performance.

  Baseline and immediately after the 8-week intervention

• Change in standing long jump distance

  Horizontal jump performance was assessed using the standing long jump test. Jump distance was recorded in centimetres. Higher values indicate better horizontal jump performance.

  Baseline and immediately after the 8-week intervention

• Change in quick feet test time

  Footwork performance was assessed using a 10 m ladder-based quick feet test. Time was recorded in seconds. Lower values indicate better footwork performance.

  Baseline and immediately after the 8-week intervention

• Change in zig-zag running test time

  Multidirectional running performance was assessed using the zig-zag running test. Time was recorded in seconds. Lower values indicate better multidirectional movement performance.

  Baseline and immediately after the 8-week intervention

• Change in body mass index

  Body mass index was calculated from measured body mass and height and reported as kg/m².

  Baseline and immediately after the 8-week intervention

Study Arms (2)

Plyometric training plus routine football training

EXPERIMENTAL

Participants in this arm received an 8-week supervised plyometric training programme in addition to their routine football training. Outcomes were assessed at baseline and immediately after the 8-week intervention period.

Behavioral: 8-week plyometric training programme; Behavioral: Routine football training

Routine football training

ACTIVE COMPARATOR

Participants in this arm continued their routine football training during the same 8-week period and did not receive the additional plyometric training programme. Outcomes were assessed at baseline and immediately after the 8-week period.

Behavioral: Routine football training

Interventions

8-week plyometric training programme BEHAVIORAL

A supervised 8-week plyometric exercise programme added to routine football training. The programme included progressive plyometric exercises designed to improve lower-limb explosive power, sprint performance, jump performance, and agility-related performance in recreational adolescent male football players.

Plyometric training plus routine football training

Routine football training BEHAVIORAL

Participants maintained their usual football training programme during the 8-week study period. This training exposure was continued in both study arms and served as the active comparator condition for the control group.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: No masking was implemented because of the visible nature of the exercise intervention. Participants and outcome assessors were aware of group allocation.
• Purpose: OTHER
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Researcher

Model Details: Participants were randomized into two parallel groups. The experimental group received an 8-week supervised plyometric training programme in addition to routine football training, whereas the control group continued routine football training only.
