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.
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.

Female school going basketball players will be screened for eligibility according to inclusion and exclusion criteria. Informed consent will be obtained from eligible participants.

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.

| Measure | Description | Time Frame |
|---|---|---|
| 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. | 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 | 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. | 8-weeks |
