Running fast is not the same as sprinting. A lot of training lives in the gray zone. 70…80…90 percent effort. Volume builds. Athletes feel prepared. But sprinting doesn’t scale up gradually. The biomechanics change abruptly as athletes approach maximal velocity. Hamstring force increases dramatically. Muscle tendon lengths approach their limits. Coordination patterns shift to handle the rapid braking of the swing limb. If athletes never experience those conditions in training, the tissue and ner

Soleus Muscle's Role in Sprinting Speed

The muscle tendon unit doesn’t adapt uniformly. Muscle fibers can change in size, stiffness, and contractile properties relatively quickly. Tendon can’t. Tendon adapts more slowly. Max velocity sprinting is a movement built around tendon behavior. The late swing to ground contact sequence depends on the hamstrings holding tension almost isometrically while the Achilles and plantar flexors stretch and recoil. That’s where the elastic action comes from. If the tendon can’t take load or doesn’t sti

Can Muscle Make You Slower?This isn’t an anti-strength or anti-muscle post.I actually dedicate an entire chapter to this in my latest e-book, Speed Kills.For most athletes, the answer is simple…you do need more muscle and you do need to get much stronger.But at a certain point, it becomes less about adding and more about refining.This is for the people who like nuance, who think beyond trends and start viewing performance through a sharper lens.More scalpel than sledgehammer.When you train this

A lot of conversations around stiffness miss the point because they treat it like one quality. Tendon stiffness and muscle stiffness adapt to different stimuli and both matter if the goal is speed. Heavy strength work and long duration ISOs expose the tendon to high strain for long enough to drive structural change. That’s why they’re so effective for tendon stiffness. You’re improving the tissue’s ability to resist deformation and transfer force quickly. Plyometrics live on the other end of the

When we break down sprinting, the muscle demands aren’t static…they shift depending on whether you’re accelerating or already at max velocity.In accel, the gastroc and soleus were the major accelerators, contributing the largest share of propulsive impulse across 19 steps. The hamstrings and glute medius also assisted, while the quads (vasti, rectus femoris) acted more as brakes…slowing the body down in early stance even though they’re producing high forces. Soleus and gastroc were critical, but

Let’s debunk a popular myth with some empowering truth! Many people, particularly women, shy away from heavy weight training out of fear that they’ll suddenly transform into a muscle-bound figure. Here’s the real deal: while it’s true that lifting heavier weights can enhance muscle growth, the notion that it automatically results in a bulky appearance is a total misconception. Embrace the weights, because they’re your allies in sculpting a strong, confident, and fabulous you! | Chontel Duncan
