About this study
Official title: The Acute and Accumulative Effects of Almonds on Exercise Recovery
The purpose of the research is two-fold. One goal is to determine if post-exercise almond or cereal bar consumption can promote muscle gain as well as increasing muscular strength throughout an eight-week weight training program. The other goal is to assess the short-term effects of almonds or cereal bar on recovery that may explain the overall long-term adaptations.
- Conditions
- Muscle Strength
- Being tested
- Cereal Bar as a recovery food snack, Almond

Questions about this trial
What is this clinical trial studying?
A study testing Cereal Bar as a recovery food snack and Almond in people with Muscle Strength, run by San Diego State University at 1 site in United States.
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 7 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 Jul 2026. 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 States. 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?
delayed onset of muscle soreness (time frame: baseline, 24 hour, 48 hour, and 72 hour after baseline). The study lists 4 primary outcomes in all. 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 6 Jul 2026.
