About this study
Official title: Effects of Plyometric Training on Linear Sprint, Change-of-Direction, and Isokinetic Strength Performances in Male Basketball Players
This study aims to evaluate the effects of an 8-week plyometric training program on the physical performance of male basketball players. The research focuses on measuring improvements in linear sprinting speed, change-of-direction (agility) abilities, and vertical jump height. Additionally, the study examines changes in the participants' muscle strength through isokinetic testing. Twenty-four trained basketball players were divided into two groups: the control group followed their regular basketball training, while the experimental group added specific plyometric exercises, such as jumps and bounds, twice per week. By comparing the results before and after the 8-week intervention period, the study seeks to determine if this training method effectively enhances the athletic skills required in competitive basketball.
Read the detailed description
This randomized controlled trial was designed to investigate the multidimensional effects of a structured plyometric training (PT) intervention on competitive male basketball players. While vertical jump performance is a common focus in PT research, this study specifically evaluates the transfer of adaptations to sport-specific locomotor tasks and isokinetic muscle strength profiles.Participants (N = 24) were randomly assigned to either an experimental group (EG) or a control group (CG). Both groups maintained their standard basketball training, including shooting, 3-on-3 games, and defensive drills. The EG performed an additional 8-week progressive plyometric program twice weekly, consisting of exercises such as box jumps, depth jumps, and bounding, with a total volume ranging from 80 to 140 ground contacts per session. Training volume was meticulously logged, and an adherence rate of at least 85% was required for inclusion in the final analysis.Performance was evaluated through a comprehensive testing battery conducted pre- and post-intervention under standardized conditions. The primary outcomes focused on linear sprint speed (25-meter sprint) and change-of-direction (CoD) ability (V-cut test), which are critical for the high-intensity demands of basketball. Secondary outcomes included vertical jump height measured via countermovement jump (CMJ) with and without arm swing, and isokinetic knee and hip strength assessed at angular velocities of 60 degrees per second and 180 degrees per second.The study hypothesized that the addition of PT would lead to superior gains in sprint and CoD performance compared to basketball training alone. Furthermore, it aimed to explore whether these performance improvements are accompanied by significant changes in isokinetic torque production. Data were analyzed using a 2 (Time) x 2 (Group) repeated-measures ANOVA to identify significant interactions. Normality was verified using Skewness and Kurtosis z-scores, with Winsorization applied to outliers to maintain data robustness.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
8-Week Progressive Plyometric Training ProgramOther
Also called Plyometric Training, Stretch-Shortening Cycle Training, Lower-Body Power Training, Explosive Strength Training
The intervention consists of a structured 8-week progressive plyometric training (PT) program designed specifically for competitive basketball players. It is performed twice weekly as a supplement to standard technical and tactical basketball drills.
- Progressive Volume: The training dosage is strictly controlled based on ground contacts per session, progressing from 80 contacts during Weeks 1 to 2, up to 140 contacts during Weeks 7 to 8.
- Movement Protocols: The protocol includes multi-planar movements such as vertical (box jumps, countermovement jumps), horizontal (broad jumps), and lateral (lateral bounds) exercises to simulate basketball-specific demands.
- Execution \& Recovery: Exercises are performed at maximal effort, focusing on minimizing ground contact time to optimize the stretch-shortening cycle (SSC). Sessions occur on a standard basketball court for surface adaptation. A recovery period of 48 to 72 hours is provided between sessions to prevent overtraining.
| Study group | Role | What they receive |
|---|---|---|
| Plyometric Training | Experimental | Participants in the Experimental Group (EG) followed a structured, progressive 8-week plyometric training (PT) program integrated into their regular basketball routine. The intervention was administered twice weekly (Tuesdays and Thursdays) with at least 48 hours of recovery between sessions. The program included vertical, horizontal, and lateral movements such as countermovement jumps (CMJ), box jumps, depth jumps, lateral bounds, and squat jumps. The volume progressed from 80 ground contacts per session in the first two weeks to 140 ground contacts per session in the final two weeks. Exercises were performed at maximal effort to maximize the utilization of the stretch-shortening cycle (SSC). All sessions were supervised by a certified strength and conditioning specialist to ensure proper technique and safety. This program was performed in addition to their standard technical and tactical basketball drills, which were identical to those performed by the control group. Receives: Other: 8-Week Progressive Plyometric Training Program |
| Standard Basketball Training | No intervention | Participants in the Control Group (CG) followed their standard basketball training routine for a duration of 8 weeks. This arm serves as the baseline to compare the specific effects of the plyometric intervention administered to the experimental group. The sessions consisted of standard technical and tactical basketball drills, including shooting practice, defensive positioning, offensive sets, and scrimmages (e.g., 3-on-3 or 5-on-5 games). Participants maintained their regular schedule of five training sessions per week, with each session lasting approximately 90 to 120 minutes. Participants in this group did not participate in any structured plyometric, strength, or power-based conditioning programs during the study period. All participants were instructed to maintain their normal nutritional habits and daily physical activities to ensure that no external variables influenced the performance outcomes. |
What is being measured
The primary outcome is the main question the study is designed to answer.
25-meter Linear Sprint Time
Time taken to complete a 25-meter straight-line sprint from a standing start. This measure evaluates linear speed and explosive acceleration. The test is conducted on a basketball court using electronic timing gates, with the best time of three trials recorded to ensure data accuracy.
Measured: Baseline (Week 0) and Post-intervention (Week 8).
V-cut Agility Test Time
Time taken to complete the V-cut agility test, which requires participants to perform four 25-degree directional changes over a 20-meter distance. This measure evaluates change-of-direction speed and maneuverability. The best time of three trials is recorded in seconds using electronic timing gates.
Measured: Baseline (Week 0) and Post-intervention (Week 8).
Secondary outcomes (2)
Countermovement Jump (CMJ) Height
Assessment of explosive lower-body power. Measured using an Optojump photoelectric system (Microgate, Italy) while participants perform a maximal vertical jump with hands on hips.
Measured: Baseline (Week 0) and Post-intervention (Week 8).
Isokinetic Peak Torque of Knee Extensors and Flexors
Maximal concentric muscle strength of the knee extensors and flexors is measured at angular velocities of 60 degrees per second and 180 degrees per second. Assessments are performed using an isokinetic dynamometer (Isomed 2000, D\&R Ferstl GmbH, Germany). The peak torque value from five maximal repetitions at each speed is recorded.
Measured: Baseline (Week 0) and Post-intervention (Week 8).

- The study followed a pre-test/post-test parallel-group randomized design. A total of 24 male basketball players were assigned to one of two arms: 1. Experimental Group (n = 12): Participants integrated a progressive plyometric training (PT) program into their routine basketball schedule. The PT was performed twice weekly (Tuesdays and Thursdays) for 8 weeks, focusing on high-intensity jumping and bounding exercises to enhance the stretch-shortening cycle. 2. Control Group (n = 12): Participants continued their standard basketball training program (technical and tactical drills) without any additional plyometric intervention. Both groups were assessed simultaneously at baseline (Week 0) and post-intervention (Week 8) using the same testing battery (25-meter sprint, V-cut agility, countermovement jump, and isokinetic dynamometry) under identical environmental conditions to ensure comparability.
