Read the detailed description
This study purpose is to compare effects of high-intensity and eccentric resistance training on squat strength, dynamic balance, and explosive power among school going basketball players.
This will be experimental randomized clinical trial conducted in Pakistan sports board, Sacred Heart cathedral high school . Female school going basketball players will be screened for eligibility according to inclusion and exclusion criteria. Informed consent will be obtained from eligible participants. All participants will go through randomization by Online Randomization tool. Information regarding number of groups, number of participants in each group and total number of participants will be entered. This will be a single blinded study in which outcome assessor will be blinded to ensure accuracy and reduce biasness. Sample size according to G power will be 40. Group A will receive high intensity resistance training, 8-week duration for significant results. Exercises will be performed at starting 50% of one-repetition maximum (1RM) for hypertrophy and strength gains. Group B will receive eccentric resistance training, 8-week duration for significant results, exercise training three times a week. Training will start at 50% of maximum eccentric force, with adjustments made bi-weekly to maintain this intensity as strength improves. Trainings will be conducted 2-3 times per week includes 3-6 sets of 6-12 repetitions with rest intervals of 30 seconds to 2 minutes. Both groups will be assessed by 1RM squat strength, YBT test and vertical jump test before after training. Objective of this research will be to determine comparative effects of high intensity and eccentric resistance training on squat strength, dynamic balance and power. The data will be analyzed using SPSS version 26 for Windows software. Statistical significance will be set at P = 0.05.

Group B receive eccentric resistance training, 8-week duration for significant results, exercise training three times a week.
| Study group | Role | What they receive |
|---|---|---|
| Group A | Experimental | 20 participants in group A will receive high intensity resistance training, 8-week duration for significant results. Exercises will be performed at starting 50% of one-repetition maximum (1RM) for hypertrophy and strength gains. Receives: Other: High intensity resistance training |
| Group B | Active comparator | 20 participants in group B will receive eccentric resistance training, 8-week duration for significant results, exercise training three times a week. Receives: Other: Eccentric resistance training |
What is being measured
The primary outcome is the main question the study is designed to answer.
1RM squat strength
The one-repetition maximum (1RM) test is a widely used strength assessment that measures the maximum amount of weight an individual can lift for a single repetition of a given exercise.This test is typically conducted after a proper warm-up and involves gradually increasing the weight until the participant reaches their maximum lift capacity. The 1RM is a valuable indicator of muscular strength and is commonly utilized in strength training programs.
Measured: 8 weeks
vertical jump
The vertical jump is frequently used as a measurement of lower-body explosive power in the strength and conditioning field. Coaches and researchers consider vertical jump height as one of the essential athletic skills that translate into increased performance in the athlete's respective sport. Vertical jump training is frequently implemented in sports that require explosive movements
Measured: 8-weeks
Y balance test
To perform the Y-Balance Test, an individual stands on one leg and reaches with the other foot to push a sliding box in three directions: anterior (forward), posterolateral (back and to the outside), and posteromedial (back and to the inside), measuring the farthest reach in each direction while maintaining balance. After practice trials, three recorded attempts are made for each direction on each leg.
Measured: 8-weeks

The record says: finished, as of the sponsor's last update on 9 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
1RM squat strength (time frame: 8 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07329439, which also lists 6 linked publications.
