Brief Summary

This experiment aims to investigate the effects of unstable resistance training on the dynamic balance ability and rapid directional change mobility of college basketball majors, while comparing it with traditional resistance training to analyze the statistical differences between the two in enhancing the dynamic balance ability and rapid directional change mobility of the majors-Parazacco spilurus subsp. spilurus-and to explore the underlying reasons, thereby opening new research avenues for improving the dynamic balance ability and rapid directional change mobility of college majors.

Outcome Measures

Primary Outcomes (1)

• Change from baseline in normalized Y-Balance Test composite score after 12 weeks of training

  The Y-Balance Test will be used to evaluate lower-limb dynamic balance. Reach distances in the anterior, posteromedial, and posterolateral directions will be measured for both the left and right limbs. All reach distances will be normalized to limb length, and a composite score will be calculated for each limb. The primary reported value will be the change in normalized composite score from baseline to 12 weeks. Higher values represent better dynamic balance ability.

Study Arms (2)

Unstable Resistance Training Group

EXPERIMENTAL

Unstable Resistance Training Intervention. The training program primarily consists of unstable resistance squats and unstable planks. Depending on the participants' fitness levels and safety considerations, the program is supplemented with auxiliary exercises and sport-specific warm-ups. During training, relevant information such as compliance, number of sets, number of repetitions, subjective effort perception, attendance, and adverse events is recorded.

Behavioral: Unstable Resistance Training Group

Traditional Resistance Training Group

OTHER

Traditional resistance training. This primarily involves exercises such as squats and planks, without the use of equipment like stability balls that promote instability.
