We have noticed that when running 200 or 100 m sprints (6 or 8 sets) that athletes get acute hamstring and calf injuries. Any suggestions?

Are they warming up enough?
An episode with things to include in a run warm up
It could be a running technique issue.
Are they letting their heel kiss the ground?
If not their calf is contracted the entire time.
It could be a landing error.
If the person is landing on their toes vs landing ball of foot that may be the cause.

How about checking their eccentric hamstring strength?When sprinting those distances you put a lot of work into the hamstrings as they try to control the leg and you have a rapid change from concentric to eccentric muscle work.A recommendation is that you should have 80% in the hamstrings of what you have in the quadriceps.If these sprints are repeated the muscles get tired and thats when you typically have these injuries and therefore eccentric strength and endurance in the muscles is important.

Yes, people in general and especially women tend to be quad dominant. If they’re not staying on the balls of the feet the force is absorbed through the calf and even further up depending on how hard they’re landing. With regards to the hamstrings the number one exercise that will reduce if not eliminate hamstring and posterior chain injuries in general is the glute hamstring raise. I try to do 2×10 or 3×5 after every deadlift workout and it has eliminated lower back pain and hamstring issues. Oh and powerful glutes are good for sprinting or so I’ve heard.
