⬆️ Resistance exercises lead to an increase in both myofibrillar and muscle connective protein synthesis rates in male and female recreational athletes. During recovery from exercise, consuming whey protein further amplifies myofibrillar synthesis rates, but it doesn't affect muscle connective protein synthesis rates. Meanwhile, ingesting collagen protein during recovery from acute exercise does not enhance either myofibrillar or muscle connective protein synthesis rates.
👀 This understanding aligns with the fact that protein synthesis across all cells is triggered by mTOR, a protein complex that specifically detects the presence of the essential amino acid leucine. When leucine is unavailable, both mTOR activity and protein synthesis are not at their peak. Despite collagen protein being rich in key amino acids that contribute to connective tissue development, especially proline, it lacks leucine. Consequently, even with these vital amino acids, without the trigger (leucine) to instigate the synthesis of new proteins, there will be no significant impact on the synthesis of connective tissue proteins.
TLDR, save your money…
