What range of protein intake is recommended for athletes over the age of 40?

The recommended protein intake for athletes over the age of 40 is typically in the range of 1.2 to 2.0 grams of protein per kilogram of body weight each day. As individuals age, there is a natural decline in muscle mass and function, a condition known as sarcopenia, which can be mitigated through adequate protein intake. This is particularly important for active individuals or athletes, as higher protein consumption can help preserve muscle mass, support recovery, and improve overall strength and performance.

The choice of 1.6 to 2.0 g/kg/day acknowledges that older athletes may require even higher protein intake compared to their younger counterparts to support these factors. This range helps address both the needs caused by aging and the demands of athletic training and competition. Proper protein consumption can also aid in reducing the risk of injury and support metabolic health during aging.

In contrast, lower protein intake ranges may not sufficiently meet the heightened requirements for maintaining muscle mass and function in this age group. Thus, the recommended range of 1.6 to 2.0 g/kg/day effectively supports the unique nutritional needs of athletes over 40, making it the most appropriate choice in this context.
