Time Based Effects of Different Duration Stretching on Calf Muscle Strength
A study testing Muscle Static Stretching in people with Muscle Strength, run by King Saud University at 1 site in Saudi Arabia.
Trial summary
Stretching is reported to decrease muscle strength and thus suggested to be avoided prior to athletic events but with conflicting reports. This time course study aimed to assess acute effects of static stretching of different durations on isometric maximum voluntary contraction force of calf muscle. Read more about this study

About this study
Official title: Time-based Effects of Different Duration Stretching on Calf Muscle Strength
Stretching is reported to decrease muscle strength and thus suggested to be avoided prior to athletic events but with conflicting reports. This time course study aimed to assess acute effects of static stretching of different durations on isometric maximum voluntary contraction force of calf muscle.

Stretching is reported to decrease muscle strength and thus suggested to be avoided prior to athletic events but with conflicting reports. This time course study aimed to assess acute effects of static stretching of different durations on isometric maximum voluntary contraction force of calf muscle. Pretest posttest experimental design was used. 14 subjects participated in three experimental trials: Static stretching for 2 minutes (SS2), static stretching for 4 minutes (SS4), and static stretching for 8 minutes (SS8). Strength was measured before (pre), immediately after (post), and at 10- and 20- minutes post stretching. Each static stretching (SS) trial involved varied repetitions of 30-seconds self-stretches and 20-seconds relax periods.

Questions about this trial
What is this clinical trial studying?
A study testing Muscle Static Stretching in people with Muscle Strength, run by King Saud University at 1 site in Saudi Arabia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Saudi Arabia. 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?
Change in Isometric Maximum Voluntary Contraction Force (time frame: MVCF at baseline and 0, 10, 20-min post stretching). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2020.
