Brief Summary

This study examined whether a 10-week dynamic stability training program using water-filled equipment could improve joint control and postural stability during landing and directional changes. Twenty-six healthy young men were randomly assigned to either a training group, which performed water-based exercises, or a control group, which did not receive any intervention. All participants performed a landing followed by a 90-degree cutting task, and joint moment data were collected using a 3D motion capture system. The study aimed to determine if water-based perturbation training enhances neuromuscular control and reduces biomechanical stress during complex movements.

Conditions

Healthy Volunteers; Physical Fitness; Lower Extremity

Keywords

Inertial load of water; Dynamic Stability Training; Joint Moments; Landing and Cutting

Outcome Measures

Primary Outcomes (1)

• Peak Joint Moment of the Lower Extremity During Landing and Cutting

  This outcome includes the peak moments of the hip, knee, and ankle joints in all three planes (sagittal, frontal, and transverse) measured during the landing and subsequent 90-degree change-of-direction task. The values are derived using a 3D motion capture system to calculate inverse dynamics.

  Baseline and after 10 weeks of intervention

Study Arms (2)

Inertial load of water Training

EXPERIMENTAL

Participants in this group performed dynamic stability training using a water-filled bag (AquaBag) for 10 weeks to improve lower limb Joint moments during landing and cutting tasks.

Behavioral: Dynamic Stability Training with Inertial load of water

Control

NO INTERVENTION

Participants in this group did not receive any training intervention during the 10-week study period.

Interventions

Dynamic Stability Training with Inertial load of water BEHAVIORAL

A 10-week training program using AquaBag to enhance lower limb joint stability and neuromuscular coordination. Exercises included dynamic stepping, lunging, and landing tasks under water load-induced perturbations.
