About this study

Official title: The Effect of Vegan or Animal Protein Ingestion on the Recovery of Skeletal Muscle Function Following Strenuous Exercise

This study will assess the effect of daily post-exercise vegan (pea) and animal (whey) protein ingestion compared to placebo over 7 days of recovery from strenuous exercise. Muscle strength and soreness will be measured daily, and mechanisms underpinning recovery will be investigated in muscle biopsies taken 3, 24 and 48 hours after exercise.

Read the detailed description

Strenuous exercise can cause muscle soreness and reduced muscle strength. It is widely acknowledged that nutritional supplements derived from animal protein sources, including whey from milk, aids recovery when taken immediately after strenuous exercise. However, the effect of vegan protein supplements are less understood, and how they affect recovery of strength and soreness is not known. This is an important area of research due to the increasing demand for plant-based protein.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in isokinetic work (W30) performed before and every 24 h after performing 300 maximal eccentric quadriceps contractions.

    The recovery of skeletal muscle isokinetic force production following eccentric exercise using an isokinetic dynamometer

    Measured: Once per 24 hour period for 7 days

Secondary outcomes (5)
  1. Perceived quadriceps muscle soreness

    Soreness will be assessed using a visual analogue scale (VAS) to determine whether the protein supplement can reduce muscle soreness following eccentric exercise. This scale will represent a 100mm line with no pain and worst pain anchored at either end of the scale.

    Measured: Once per 24 hour period for 7 days

  2. Muscle swelling

    Determine whether the protein supplement can reduce muscle swelling following eccentric exercise assessed using MRI

    Measured: Once per 24 hour period for 3 days

  3. Rate of protein incorporation into the muscle

    Determine whether the strenuous exercise and a protein supplement can upregulate protein synthesis following strenuous exercise assessed by muscle biopsies

    Measured: Once per 24 hour period for 3 days

  4. Plasma creatine kinase (CK) activity before and every 24 h after performing 300 maximal eccentric quadriceps contractions.

    Damage and inflammatory bio markers following strenuous exercise assessed by blood sample

    Measured: Once per 24 hour period for 7 days

  5. Change in flow mediated dilation

    Determine whether the protein polyphenol supplement can impact vascular function following eccentric exercise

    Measured: Once hourly post exercise for 3 hours

Questions about this trial

What is this clinical trial studying?

A study testing Recovery animal (20g whey) protein supplement and Recover vegan (26g pea) protein supplement in people with Muscle Recovery, run by University of Exeter 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 2 inclusion and 9 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 22 Mar 2023. 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. Some participants in this study may receive a placebo. 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 isokinetic work (W30) performed before and every 24 h after performing 300 maximal eccentric quadriceps contractions. (time frame: Once per 24 hour period for 7 days). 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 22 Mar 2023.
