About this trial
This randomized controlled trial aims to determine the effects of different drop height plyometric training protocols on lower limb explosive strength, anaerobic power, and change of direction (COD) performance in soccer players. A total of 56 competitive soccer players aged 18-30 years will be randomly allocated into three intervention groups using sealed envelope randomization: low drop height (30 cm), moderate drop height (45 cm), and high drop height (60 cm) plyometric training groups. Participants will undergo supervised plyometric training three times per week for six weeks. Outcome measures including Vertical Jump Test, Running-Based Anaerobic Sprint Test (RAST), and T-Test Agility Test will be assessed at baseline and post-intervention. Statistical analysis will be performed using SPSS version 25 to determine within-group and between-group differences.

Trial outcomes
Primary outcomes
1
Lower Limb Explosive Strength
Explosive strength will be measured using the Vertical Jump Test. Jump height will be recorded and peak power will be calculated using the Sayers Equation.
Time frame
Baseline; 7-Week Post-Intervention2
Anaerobic Power
Anaerobic power will be assessed using the Running-Based Anaerobic Sprint Test (RAST). Peak power, average power and fatigue index will be calculated.
Time frame
Baseline: 7-Week Post-Intervention3
Change of Direction Performance
Change of direction ability will be assessed using the T-Test Agility Test and recorded in seconds.
