About this study
Official title: The Effects of Integrated Neuromuscular Training on Repeated Jumping Performance in Collegiate Volleyball Players
This randomized controlled study evaluated whether adding integrated neuromuscular training (INT) to regular volleyball instruction could improve repeated jumping performance in collegiate volleyball players. Thirty-four participants were randomly assigned to an INT group or a control group. Both groups continued the same conventional volleyball instruction, while the INT group also received structured neuromuscular training twice per week for 9 weeks. The INT program included plyometric exercises, strength training, core stabilization, and speed-agility drills. Repeated jumping performance was assessed before the intervention, immediately after the 9-week intervention, and after a further 3-week follow-up period. Participants completed three Continuous Countermovement Semi-Squat Jump (CCSJ) protocols: five consecutive jumps, continuous jumping for 15 seconds, and continuous jumping for 30 seconds. Outcomes included jump height, peak force, mean force, and fatigue index.
Read the detailed description
Volleyball requires athletes to perform repeated explosive jumping actions during training and competition. The ability to maintain force production and jumping performance during repeated efforts is therefore an important component of volleyball-specific physical performance. Integrated neuromuscular training (INT) combines multiple training components, including plyometric exercise, strength training, core stabilization, and speed-agility training.
This study used a randomized controlled design to investigate the effects of adding INT to conventional volleyball instruction on repeated jumping performance in collegiate volleyball players. A total of 34 participants were randomly allocated to an INT group or a control group, with 17 participants in each group. Both groups received the same conventional volleyball instruction, including dynamic stretching and low-intensity aerobic warm-up, technical training, and tactical drills. In addition to the conventional volleyball program, participants in the INT group completed a structured INT program twice per week for 9 weeks. The control group continued conventional volleyball instruction without the additional INT program.
Repeated jumping performance was evaluated at three time points: baseline, immediately after the 9-week intervention, and after a 3-week follow-up period. Testing was performed using three Continuous Countermovement Semi-Squat Jump (CCSJ) protocols: five consecutive maximal jumps (5×), continuous maximal jumping for 15 seconds, and continuous maximal jumping for 30 seconds. Jump performance was assessed using a force plate. The main performance variables were jump height, peak force, mean force, and fatigue index.
The study was designed to determine whether changes in repeated jumping performance over time differed between the INT and control groups and whether any changes observed after the intervention were maintained during the 3-week follow-up period.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Integrated Neuromuscular TrainingBehavioural
Integrated neuromuscular training was provided twice per week for 9 weeks. The program consisted of plyometric training strength training core stabilization and speed-agility training. The training program was progressively structured across initial improvement and reinforcement phases.
Conventional Volleyball InstructionBehavioural
Conventional volleyball instruction included a 5-10 minute dynamic stretching and low-intensity aerobic warm-up followed by volleyball technical training and tactical drills.
| Study group | Role | What they receive |
|---|---|---|
| Integrated Neuromuscular Training Group | Experimental | Participants received conventional volleyball instruction plus additional integrated neuromuscular training (INT) twice per week for 9 weeks. The INT program incorporated plyometric training, strength training, core stabilization, and speed-agility exercises. Receives: Behavioral: Integrated Neuromuscular Training; Behavioral: Conventional Volleyball Instruction |
| Control Group | Active comparator | Participants received conventional volleyball instruction without the additional integrated neuromuscular training program. Conventional instruction included dynamic stretching and low-intensity aerobic warm-up, volleyball technical training, and tactical drills. Receives: Behavioral: Integrated Neuromuscular Training; Behavioral: Conventional Volleyball Instruction |
What is being measured
The primary outcome is the main question the study is designed to answer.
Peak Force During Repeated Jumping
Peak force was measured during the 5×, 15-second, and 30-second CCSJ protocols using the ELIGA-T132 force plate. Peak force represents the maximum force generated during the repeated-jump task and was expressed in newtons (N).
Measured: Baseline, immediately after the 9-week intervention, and at the 3-week follow-up (week 12)
Jump Height During Repeated Jumping
Jump height was measured during three Continuous Countermovement Semi-Squat Jump (CCSJ) protocols: five consecutive maximal jumps (5×), continuous maximal jumping for 15 seconds, and continuous maximal jumping for 30 seconds. Jump height was measured using the ELIGA-T132 force plate and expressed in meters (m).
Measured: Baseline, immediately after the 9-week intervention, and at the 3-week follow-up (week 12)
