Biomechanical evidence strongly supports the view that sprinting is not a series of single‑leg hops. It is a coupled, history‑dependent locomotor system in which stance, flight, and swing phases are highly interconnected. Reducing sprinting to unilateral hopping may simplify coaching narratives, but it obscures the mechanisms that actually govern performance.

If you are serious about integrating force plates and timing gates into one coherent workflow, Strength By Numbers provides a connected solution through the AxIT performance platform.

In recent years, hamstring tantrums (also referred to as Swiss‑ball kicks or flutter kicks) have gained popularity, largely supported by EMG studies reporting high levels of hamstring activation during the exercise, and viral trending videos on social media. However, what's important to understand is that muscle activation alone is a poor criterion for judging the usefulness of an exercise.

Dashr gives you the ability to test speed, agility, power, reaction, and more—quickly and accurately—without complicated setups or recurring subscription fees. You can capture results instantly on your phone, give athletes immediate feedback, and still have everything synced for long-term tracking and reporting when you want it.

Current evidence suggests that the hamstrings function primarily as an eccentric energy-absorbing brake during the late-swing phase, necessary to decelerate the lower limb and manage loads that exceed isometric capacity. However, the presence of long tendons and specific architectures in muscles like the BFlh ensures that tendon contributions and spring-like behavior are also vital. The issue of hamstring behavior remains complex and multifactorial.

When it comes to locomotion, very few structures can be defined as fundamental in carrying over the responsibility of efficient performance as the intrinsic and extrinsic muscles of the foot.

Around summer 2025, Hyperice has released (in partnership with Nike) a brand-new device called the Hyperboot. This brand-new piece of equipment is basically the re-proposal of two of their patented technologies, i.e. Normatec Sequential Pulse and HyperHeat (already present on devices such as the Hyperice Venom 2), into a pair of hyper-futuristic shoes.

The sacroiliac joints (SIJs) are specialised structures that serve as stable yet slightly flexible connections between the lower limbs and the rest of the body, allowing efficient force transmission. These joints are large, flat, and combine both synovial and fibrous elements. Their highly congruent surfaces offer considerable friction, and strong ligaments further support their function, resulting in effective force transfer with minimal movement (Vleeming et al. , 2012).

p.s. This article has been originally published on the magazine Athletics Weekly (www.athleticsweekly.com) on November 2014 Most training programmes focus on teaching the concentric portion of the jumping movement and fail to work on the eccentric where the majority of injuries usually occur. Jump training was introduced by Professor Verkhoshansky at the end of the 1950s – the exercise of the jump executed by dropping from a height with vertical rebound has been a staple for
