The recommended daily protein intake for athletes is indeed in the range of 1.2 to 1.7 grams of protein per kilogram of body weight. This range is supported by numerous studies and expert guidelines, which indicate that athletes have higher protein needs compared to the general population due to the physical demands of their training and the physiological processes involved in muscle repair, recovery, and growth.

This level of intake is particularly important for those involved in endurance sports or strength training, as the increased amino acid requirements can help facilitate muscle protein synthesis. Protein also plays a crucial role in overall recovery, immune function, and the maintenance of lean body mass during periods of intense training.

In comparison, the lower ranges mentioned do not meet the enhanced demands of athletic training, while the highest range suggests excessive intake that might not be necessary or beneficial for all athletes, potentially leading to unnecessary caloric surplus and strain on renal function over time. Therefore, the chosen answer encapsulates a balanced and evidence-based approach to protein intake in athletes.
