NCT07796464

Brief Summary

Stretching is commonly used during warm-up and recovery and can influence flexibility, neuromuscular control, and joint range of motion. However, the acute effects of different stretching scopes on jump and agility performance remain unclear. This study will compare whole-body and lower-limb static stretching in 60 healthy university students randomly assigned to whole-body stretching, lower-limb stretching, or control groups. Each intervention will last 14 minutes. Jump performance will be assessed using the standing long jump, squat jump, countermovement jump, and drop jump with a Vmaxpro sensor, while agility will be evaluated using the T-Test and Hexagon Agility Test. The findings are expected to clarify how stretching scope influences acute physical performance and may inform warm-up and physical therapy strategies.

Outcome Measures

Primary Outcomes (6)

  • Hexagon Agility Test Completion Time

    Agility performance will be assessed using the Hexagon Agility Test. Participants will complete two valid trials, and the mean completion time will be used for analysis. Completion time will be recorded in seconds, with a shorter time indicating better agility performance.

    From baseline to immediately after the 15-min intervention

  • T-Test Agility Test Completion Time

    Agility performance will be assessed using the T-Test Agility Test. Participants will complete two trials, and completion time will be recorded in seconds using a photocell timing gate system. The mean completion time of the two trials will be used for analysis, with lower values indicating better agility performance.

    From baseline to immediately after the 15-min intervention

  • Squat jump height

    Squat jump performance will be assessed using a wireless inertial measurement sensor. Participants will perform two valid squat jump trials, and the mean jump height will be used for analysis. Jump height will be recorded in centimeters, with higher values indicating better jump performance.

    From baseline to immediately after the 15-min intervention

  • Countermovement Jump Height

    Countermovement jump performance will be assessed using a wireless inertial measurement sensor. Participants will perform two valid countermovement jump trials, and the mean jump height will be used for analysis. Jump height will be recorded in centimeters, with higher values indicating better jump performance.

    From baseline to immediately after the 15-min intervention

  • Drop Jump Reactive Strength Index

    Reactive strength during the drop jump will be assessed using a wireless inertial measurement sensor. The reactive strength index will be calculated as jump height divided by ground contact time. Participants will perform two valid trials, and the mean reactive strength index will be used for analysis. Values will be expressed in meters per second, with higher values indicating better reactive strength performance.

    From baseline to immediately after the 15-min intervention

  • Standing Long Jump Distance

    Horizontal lower-limb explosive performance will be assessed using the standing long jump. Participants will perform two valid trials, and the mean jump distance will be used for analysis. Jump distance will be recorded in centimeters, with higher values indicating better performance.

    From baseline to immediately after the 15-min intervention

Study Arms (3)

Whole-Body Stretching

EXPERIMENTAL

Participants assigned to this arm performed a whole-body static stretching protocol targeting the neck, trunk, upper limbs, and lower limbs. The intervention lasted approximately 15 minutes.

Behavioral: Whole-Body Static Stretching

Lower-Limb Stretching Group

EXPERIMENTAL

Participants assigned to this arm performed a lower-limb static stretching protocol primarily targeting the major muscle groups of the lower extremities. The intervention lasted approximately 15 minutes.

Behavioral: Lower-Limb Static Stretching

Non-Stretching Control Group

NO INTERVENTION

Participants assigned to this arm received no stretching intervention and remained seated quietly for approximately 15 minutes.

Interventions

Participants performed a whole-body static stretching protocol targeting the neck, trunk, upper limbs, and lower limbs for approximately 15 minutes.

Whole-Body Stretching

Participants performed a lower-limb static stretching protocol primarily targeting the major muscle groups of the lower extremities for approximately 15 minutes.

Lower-Limb Stretching Group

Masking Details
Outcome assessors were blinded to group allocation during post-intervention performance assessments. Participants and personnel delivering the assigned intervention were aware of group allocation because of the nature of the stretching protocols.
Purpose
OTHER
Intervention Model
PARALLEL
Model Details: Participants were randomly assigned in parallel to one of three groups: whole-body static stretching, lower-limb static stretching, or a non-stretching control condition. Each participant received only the assigned condition, and acute changes in agility and lower-limb explosive performance were assessed before and after the intervention.
