About this study
Official title: Do Stretching Variations Affect Performance? A Comparison of Full-Body and Lower-Limb Stretching on Explosive Power and Agility Reaction Time
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.
Read the detailed description
Stretching exercise is one of the most commonly used strategies for pre-exercise warm-up and post-exercise recovery, and its physiological effects involve muscle flexibility, neuromuscular control, and joint range of motion. However, empirical evidence regarding the acute effects of different stretching scopes on jumping ability and agility remains relatively limited, as most previous studies have focused on individual muscles or localized muscle groups. Therefore, the present study aims to investigate the effects of static stretching involving different body regions, specifically whole-body and lower-limb stretching, on explosive performance and agility.
A pretest-intervention-posttest design will be adopted. A total of 60 healthy university students (30 males and 30 females) are expected to be recruited and randomly assigned to a whole-body stretching group (10 males and 10 females), a lower-limb stretching group (10 males and 10 females), or a control group (10 males and 10 females). The duration of the static stretching intervention will be standardized to 14 minutes. The whole-body stretching group will perform stretching exercises targeting the major muscle groups of the upper limbs, trunk, and lower limbs, whereas the lower-limb stretching group will focus on key lower-limb muscle groups, including the quadriceps, hamstrings, and gastrocnemius. The control group will remain seated quietly for 14 minutes without performing any stretching exercise.
Participants will undergo a series of physical performance assessments before and after the intervention. Jump performance will be evaluated using the standing long jump, squat jump, countermovement jump, and drop jump. All jump-related data will be recorded using a Vmaxpro wireless inertial measurement sensor (BM Sports Technology GmbH, Germany), providing key parameters such as jump height, peak velocity, and peak power. Agility will be assessed using the T-Test and Hexagon Agility Test.
It is hypothesized that excessive static stretching may cause an acute reduction in muscular strength and explosive performance. The whole-body stretching group may demonstrate only a slight decrease in jump performance while maintaining relatively stable agility performance, whereas the lower-limb stretching group may exhibit changes in both jump and agility performance. The findings of this study are expected to clarify the relationship between the scope of static stretching and subsequent physical performance and may provide evidence to support the design of pre-exercise warm-up strategies and physical therapy interventions.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: 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.
Measured: 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.
Measured: 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.
Measured: 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.
Measured: From baseline to immediately after the 15-min intervention

Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hexagon Agility Test Completion Time (time frame: From baseline to immediately after the 15-min intervention). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
