What's the main thing that drives performance down with age into an athlete's 30s?
What's the primary reason athletes, or even performance-oriented hobbyists, begin to decline performance-wise in their 30s assuming they were completely dialed in during their 20s? I know many people have made the best athletic progress of their lives into their 30s and beyond, but peak performance and recovery capacity seems to take a hit for top-performers compared to the previous decade. Is it primarily down to testosterone, wear-and-tear on joints or ligaments, or something else entirely?
