Omega-3 in weight training

Resistance training (or weight training) increases muscle strength by making the muscles work against a weight or force; it is based on the principle that muscles will work to overcome a resistance force when they are required to do so. The best way to develop muscle strength is to force the muscle to contract to its maximum potential at any given time, and, after, let it time to repair and […]

 
 
 
 

DHA as a preventive measure in contact sports

Concern regarding the number of mild traumatic brain injuries and its associated long-term neurological damage in players of contact sports is raising. Among American football players (and athletes in other sports such as ice hockey), brain trauma may be less the result of violent collisions that cause concussions than the cumulative effect of repetitive head impacts; American football players can experience hundreds of non-concussive hits during a single season. A […]

 
 
 
 

Omega-3 and muscle health

Skeletal muscle is highly adaptable to diet and physical activity levels. So, the response of skeletal muscle to exercise can be modified by the nutritional status. The amount and type of fat in the diet play an important role in regulating body metabolic health: saturated fatty acids have been linked with the development of metabolic dysfunction while some monounsaturated fatty acids and polyunsaturated fatty acids have positive effects on metabolic […]

 
 
 
 

Oxidative stress, exercise and EPA

During exercise, increased “reactive oxygen species” production occurs, and this can lead to a decline of individual’s performance and health (due to cell damage). “Reactive oxygen species” are chemically reactive molecules containing oxygen and have important roles in normal functioning: they are needed for the production of some hormones and normal cell functions, and are generated to kill some bacteria. But if their levels increase (during exercise, exposure to ultra […]

 
 
 
 

DHA may facilitate healing after brain trauma

A traumatic brain injury is a brain injury caused by an external physical force. The resulting damage can be confined to one area of the brain or involve more than one area, and depending on the extent of the damage, traumatic brain injury can be mild, moderate or severe. High-energy sports (rugby, soccer, hockey, basketball, squash, cycling, etc.) often lead to head and brain trauma. Sport injuries are common and […]

 
 
 
 

Omega-3 supplementation and physical performance

Omega-3 supplementation has ergogenic potential. An ergogenic aid can be defined as a physical, mechanical, nutritional, psychological, or pharmacological substance or treatment used for the purpose of enhancing physical performance, especially by eliminating fatigue symptoms. People use ergogenic aids (caffeine or sports drinks with carbohydrates and electrolytes to replace salts eliminated during sweating), but some of them have not proved effectivity and others, even, are harmful or illegal. Some ergogenic […]
