Clinical Trial Summary

The aim of the current study is to find out if krill oil can increase muscle building processes in response to resistance (weightlifting) type exercise. Others aim are to determine the effects of krill protein, and the interaction of krill oil and protein, on muscle building processes in response to resistance (weightlifting) type exercise.

Related Conditions & MeSH terms

• Hypertrophy

Intervention

Dietary Supplement:
• Krill oil
Krill oil will be supplemented to see if they can gain strength and/or muscle mass following supplementation.
• Krill protein
Krill protein will be given to the participant following a resistance exercise bout.
• Vegetable oil
This will be the control against the Krill oil
• Carbohydrate
This will be the control for the Krill protein
