An interventional study of Effects of Strength Training Combined With Omega-3s derived from algae on Muscle Strength and Cognitive Functions in adults and Effects of Strength Training Combined With Omega-3s derived from fish on Muscle Strength and Cognitive Functions in adults in Muscle Strength and Cognitive Function Assessment, sponsored by Gdansk University of Physical Education and Sport. Enrolling by invitation at 1 site in Poland. Open to participants aged 20 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-10-29.
Sponsored by Gdansk University of Physical Education and Sport · Not applicable, Interventional, and Basic science
The purpose of the study is to evaluate the effects of 12-week supplementation with algae-derived DHA combined with strength training on muscle strength, neuromuscular parameters, post-exercise inflammation and cognitive functions in healthy adults compared to fish-derived EPA and DHA combined with strength training, strength training plus placebo and groups receiving only supplementation (algae-derived DHA, fish-derived EPA and DHA or placebo).
The research methods and measurement tools include:
All analysis (beside IPAQ) will be performed before and after 12 weeks of intervention.

Inclusion Criteria for the training group:
For the control group (non-exercisers):
- Requirements as above, except for exercise: we recruit individuals who exercise less than 1 hour per week
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Healthy men and women with few years of training experience will participate in a 12-week strength training program combined with 3g/per day DHA from algae supplementation. The training will be 3 times a week, with 1-hour strength-training exercises for the upper and lower body. At the beginning and end of the intervention, muscle strength will be assessed along with EMG, cognitive function will be evaluated, and blood samples will be collected to measure specific proteins.
