When I do sprints, the next day my quads and inner thigh area get extremely sore but my hamstrings and glutes are fine. However, since hamstrings and glutes are the most important muscles when it comes to sprinting, does this mean that I am not recruiting them enough? [/quote]
No, it doesn’t mean a thing other than you quads may have taken a greater eccentric load.
The advise given isn’t necessarily bad, it’s just meaningless in your case since soreness is not an accurate way to judge muscle involvement.[/quote]
I agree with this advice. Soreness from the quads could be more related to the pounding with each step rather than the contraction of the muscle. So not that the advice give would hurt to try to focus further on your hamstrings, you might already be targeting your muscles just fine.
