Older adults exhibit a more significant increase in strength than muscle mass when engaging in resistance training. This phenomenon is partly attributed to older individuals being anabolically resistant to resistance exercise and not frequently engaging in it. Dr. McGlory discusses the role of nutrition, focusing on amino acids and omega-3s, in strength gains and how omega-3s appear to enhance strength in older women particularly. Drs. McGlory and Patrick also touch upon the sex differences in muscle gains and the possible influence of estrogen on the conversion of omega-3 fatty acids. In this clip, Dr. McGlory discusses the intriguing interplay between resistance training, nutrition, and muscle adaptation, especially among older adults.

An omega-3 fatty acid found in the human brain and the meat of fatty fish. DHA plays a key role in the development of eye and nerve tissues, and is essential for normal brain function in humans. DHA may also reduce the risk of Alzheimer’s disease1 and cardiovascular disease, and may be useful in treating certain inflammatory conditions, such as rheumatoid arthritis. Dietary sources of DHA include krill oil and the meat and roe of salmon, flying fish, and pollock. [1] Patrick, Rhonda P.

An omega-3 fatty acid found in the meat of fatty fish. EPA reduces inflammation in the body and helps counter oxidative stress in cells. It is crucial for modulating behavior and mood and has demonstrated beneficial effects in managing anxiety and depression. EPA may reduce risk of developing certain chronic diseases such as cancer or cardiovascular disease. Dietary sources of EPA include herring, salmon, eel, shrimp and sturgeon.
