The b skip - where hamstrings should get loaded well, but often the poor timing of the drill makes it worthless to teach to football players. Post injury , relearning the sprint cycle can be important for turning off inhibitions and rebooting co-contractions. Static a/b skip is a simple...

👀Connecting your coaching eye to your clinical reasoning! Observe the leg cycle of the leg closest to the camera on each drill. Can you see small medium then big elliptical on the right limb and very limited ones on the left? What does limb movement and synergies say about muscle properties and pelvic structure ? Does “technique” matter? Well only if you want to load specific tissues and create protective system tension. We had a really interesting 10.6 sprinter with repeated right side hamstring strains over the past year join our hamstring workshop. UPMC Sports Surgery Clinic 💪🏾Isokinetic tests have him really really strong on both limbs. 🔋Emg told a story of right side dominance and good lateral to medial hamstring balance whilst the left side was far more imbalanced with medial hamstrings dominating action that we assumed the lateral would. 🧐When we went on to the track, we saw similar things. 🚩Notably a reluctance to open up into late swing phase, avoiding long lever eccentric stress on the distal hamstrings…. ON THE LEFT LEG! Well this was noticed across a range of exercises velocities and complexities. 🏃🏾‍♀️ Drills with speed and locomotion, static fast drills as well as static slow drills. 🧐Movement illuminates structural qualities. 🧐Can you spot the difference in these two leg cycles? Could it be that the right side is repeatedly hurt due to the deficit in the left side. After all, if you can’t integrate late swing phase, then you will have poor negative foot speed. You will be able to accelerate…. But all the work will be on the right side the deeper you get into a sprint. Ed Mias Sportsmith
