SSE #170: Branched-chain amino acid supplementation to support muscle anabolism following exercise

Branched-chain amino acids (BCAA) are essential amino acids that play several important roles in muscle metabolism. The BCAAs are critical for stimulation of molecular signaling that leads to muscle protein synthesis and muscle protein breakdown. This sports science exchange will discuss the research associated with BCAAs, other nutritional sources, and their effects on muscle protein following exercise.

SSE #160: Dietary protein to support active aging

Aging is accompanied by a decline in skeletal muscle mass and strength. The loss of muscle mass with aging is at least partly attributed to a blunted muscle protein synthetic response to food intake. Physical activity increases the sensitivity of skeletal muscle tissue to the anabolic properties of protein consumption. Exercise and adequate protein consumption together attenuates age-related muscle loss and can be combined effectively to increase muscle mass, strength and functional performance in older populations.  Thus, research is ongoing to define the optimal type, amount, and appropriate timing of protein intake to further enhance the adaptive response to exercise training.

SSE #159: PROTEIN AND EXERCISE IN WEIGHT LOSS: CONSIDERATIONS FOR ATHLETES

Weight loss is common in athletes and is typically practiced with the goal of increasing the efficiency of movement and thus enhancing performance. Weight loss can be accomplished “passively”, making use of nutrition strategies only; i.e. by restricting energy intake. Several ‘diet-only’ plans have been examined in head-to-head studies, confirming there are a variety of dietary patterns which promote weight loss; all of which must create an energy deficit. However, weight loss via diet alone results in the loss of both body fat and lean tissue, which would likely include skeletal muscle and potentially the loss of bone mass. In addition to diet-only strategies, weight loss can be accomplished through increasing the volume/intensity of exercise without changes in dietary intake, or as is more common, in combination with a reduction in energy intake. Optimizing both the quantity and timing of protein intake can help mitigate losses in muscle mass. In addition to protein intake and exercise, the speed of weight loss, and hence the magnitude of the caloric deficit, can affect the ability to retain lean mass. In fact, with substantially large caloric deficits, increases in dietary protein may show diminishing effects in mitigating losses of lean tissue mass.
