Acute Effect of Static Stretching and Pilates Stretching on the Muscle Strength

Not Applicable

Completed

• Conditions: Muscle Strength; Muscle Strength Dynamometer
• Interventions: Other: Pilates stretching; Other: Static stretching

• Registration Number: NCT06151860
• Lead Sponsor: Universidade Estadual do Norte do Parana

Brief Summary

Introduction: Studies have shown that static stretching performed immediately before strength exercises impairs performance. However, unlike static stretching, dynamic stretching performed immediately before muscular strength exercises does not seem to result in worse performance, and in some cases may even provide greater strength performance. Still, the literature is controversial and inconclusive to date.

Objective: To verify the acute effect of static stretching versus dynamic stretching on the muscle strength of young university students.

Methods: The sample will consist of 102 physically active young university students, of both sexes, aged between 18 and 25 years old, subdivided into three groups: Group 1 - static stretching; Group 2 - dynamic stretching; and Group 3 - control. Everyone will undergo assessment of the isokinetic peak torque of the knee extensor and flexor muscles at 60º/s and 180º/s in the dominant lower limb. Next, the experimental groups (Groups 1 and 2) will perform static or dynamic stretching exercises for the quadriceps and hamstring muscles, while the control group will not perform any activity. Finally, everyone will undergo muscle strength assessment again according to the same procedures used initially. Analysis of covariance (ANCOVA) will be used to compare groups, with data from the initial assessment as adjustment covariates.

Arm && Interventions

Group	Intervention	Description
Pilates stretching	Pilates stretching	The protocol will be the same as the Static stretching Group, with the exception of maintaining the static position during the exercise. To do this, when stretching the knee flexor muscles, the trunk will perform continuous flexion movements until the point of muscular discomfort, followed by the extension movement, until an upright posture, continuously. On the other hand, when stretching the knee extensor muscles, the gluteal muscle of the dominant lower limb will meet the heel of the same limb, until there is discomfort, followed by the movement away, continuously.
Static stretching	Static stretching	A equipment (Ladder Barrel), used in Pilates sessions, will help with the movement. To stretch the knee flexor muscles, the participant, standing, will place the dominant lower limb on the equipment and keep the other on the ground, remaining with both knees extended. The trunk will be flexed forward within the maximum range of movement achieved by the participant, until discomfort occurs in the posterior region of the thigh, but not pain. To stretch the knee extensor muscles, the participant, standing, will position the back of the foot of the dominant lower limb on the equipment and keep the other limb with the foot flat on the ground. The glute of the dominant lower limb will meet the heel of the same limb, until there is discomfort, but not pain. In both stretches, the position will be maintained for 30 seconds, followed by an equal rest time. Three series of stretching will be performed for the knee flexor muscles and then another three series for the extensor muscles.
