Summary

Tetraselmis chuii (TetraSOD) is a marine microalgae that has been reported to improve antioxidant responses in human skeletal muscle cells treated with TetraSOD and to improve recovery from muscle damaging exercise in humans supplemented with TetraSOD. However, the effects of TetraSOD supplementation on human skeletal muscle antioxidant gene expression is less clear. This study assessed the effect of short-term TetraSOD supplementation on human skeletal muscle antioxidant gene expression in healthy adults.

Detailed description

It is well documented that the production of reactive oxygen species (ROS; unstable molecules that react easily with and damage other molecules in a cell) increases in-line with the intensity and duration of exercise . Although increased ROS production during exercise is initially managed by a variety of 'antioxidants', continued ROS production exceeds the capacity of this antioxidant defense system leading to the development of oxidative stress and impaired exercise performance. Therefore, interventions that can lessen exercise-induced oxidative stress have the potential to improve exercise performance. While dietary supplementation with antioxidant vitamins (e.g. vitamin C and E) has this potential, such interventions do not typically improve exercise performance. Therefore, further research is required to investigate the potential for novel nutritional supplements to lessen exercise-induced oxidative stress and to improve exercise performance. Tetraselmis chuii (TetraSOD) is a natural marine microalgae product. Recent preliminary evidence suggests that treating human skeletal muscle cells with TetraSOD can increase the production of antioxidant enzymes to limit oxidative stress development. In addition, TetraSOD supplementation has been reported to improve recovery from muscle damaging exercise. However, the effects of TetraSOD supplementation on on human skeletal muscle antioxidant gene expression is less clear. This study assessed the effect of short-term TetraSOD supplementation on human skeletal muscle antioxidant gene expression in healthy adults.
