About this study

Examine the impact of the protein supplements leucine, HMB and BCAA on muscle recovery and inflammatory response following acute exercise.

Read the detailed description

Participants, both females and males, will perform an acute bout of exercise. A bout of exercise that will involve multiple drop jumps. Prior to and post exercise, functional outputs will be measured and blood will be collected to quantify the inflammatory response. The protocol will involve attending the laboratory on 6 occasions over a two week period to complete the above measures.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Drop JumpsOther

    Perform 100 drop jumps from 40 cm height. The protocol is divided into 5 sets of 20 repetitions. Between each repetition participants get 10 seconds, and between each set 2 minutes rest. Stand on the box, drop of the box and land with feet shoulder width apart. Then immediately bend knee to approx 45 degrees and jump straight up. Throughout each jump hands are placed on hips and should not move.

Questions about this trial

What is this clinical trial studying?

A study testing Drop Jumps in people with Muscle Damage, run by Liverpool John Moores University at 1 site in United Kingdom.

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 1 inclusion and 22 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 6 Jan 2021. 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 United Kingdom. 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?

Concentration of Creatine Kinase at baseline (time frame: Baseline). The study lists 30 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04679519, which also lists 2 linked publications.

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 6 Jan 2021.
