Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• 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).

  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).

  Baseline, immediately after the 9-week intervention, and at the 3-week follow-up (week 12)

Study Arms (2)

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.

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.

Behavioral: Integrated Neuromuscular Training; Behavioral: Conventional Volleyball Instruction

Interventions

Integrated Neuromuscular Training BEHAVIORAL

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.

Control Group; Integrated Neuromuscular Training Group

Conventional Volleyball Instruction BEHAVIORAL

Conventional volleyball instruction included a 5-10 minute dynamic stretching and low-intensity aerobic warm-up followed by volleyball technical training and tactical drills.

Control Group; Integrated Neuromuscular Training Group
