New research shows that omega-3 fatty acids (cold water fish and fish oils are great sources) support muscle protein synthesis, or the creation of new muscle tissue in older adults. Changes were noted after 8 weeks of supplementation.
Older adults muscles breakdown more quickly than younger people; this is associated with a loss of strength and performance.
Researchers noted that the Omega-3 oils ‘turned on’ a specific anabolic (muscle building) pathway. Experimentally, this occurred when ingested with amino acids and insulin. To recreate this effect, one could take Omega-3 oils with a protein-rich meal. The body always secretes insulin when meals are eaten; consuming some carbohydrates with this meal will enhance insulin secretion. This would be a perfect post-workout meal, by the way!
Omega-3 oils are found most readily in fish oil. They can also be found in plant oils as well. EPA and DHA are common types of Omega-3 oil. Omega-3 fatty acids are beneficial for asthma, allergies, tendonitis and high cholesterol, to name a few.

Being from Colorado, we know altitude. Denver and the Front Range areas are roughly 5000+ feet, or a mile (1600 meters) high. This elevation, while nothing extreme, definitely presents a challenge to visitors.
Often times I am asked, “just how long can I rest while I recover from my injury/illness, before I start to lose my fitness level”? All of us are hesitant to give up the gains we have made from all of that training. Although this is not a straight forward question, there is plenty of enlightening research on this subject.
