After nearly four decades working at the highest levels of track and field and professional sport, one misunderstanding stands out as the most damaging and pervasive in high-performance coaching: the conflation of strength and power. These are not the same quality. They do not respond to the same training. And if you confuse them in prescription, you will systematically fail to develop the athletic attribute that determines performance in virtually every dynamic sport.

Coaching change of direction is not primarily a biomechanics problem. It is a human problem. Before any technical model can be successfully delivered, a practitioner must first establish the conditions under which an athlete will actually want to change, engage, and take ownership of the process.

Speed is one of the most coveted qualities in sport. It is pursued obsessively, dissected in slow motion, and marketed through countless training systems that promise to unlock it. Yet for all the attention it receives, speed training remains one of the most misunderstood domains in strength and conditioning.

The debate around isometrics in sprint training often swings between two extremes: either they are held up as highly specific tools that replicate sprint mechanics, or they are dismissed as irrelevant because sprinting is a dynamic, high-velocity, elastic activity. As usual, the truth sits somewhere in the middle. Isometrics are not sprint-specific in the strict biomechanical sense, but they can play a meaningful role in a well-designed program.

In recent years, the conversation around exercise specificity has drifted toward a narrow and often superficial interpretation: if an exercise looks like the sport, then it must be specific. This trend has become particularly visible in sprint training, where isometric holds in “sprint‑like” positions are frequently promoted as highly specific tools for both training and testing.

If you watch an elite sprinter at maximal velocity, the first thing that stands out is how little seems to happen. The movement looks clean, almost effortless, as if the athlete is simply letting speed carry them forward. But beneath that apparent simplicity lies a highly constrained biomechanical principle: the entire expression of sprinting is shaped by the way the foot touches the ground.

The human spine plays a paradoxical role in contemporary sport science and sports medicine discussions. On one hand, it is universally acknowledged as central to posture, movement, and force transmission. On the other, it is frequently framed as a structure that must be protected from load, rotation, and compression. Modern biomechanics challenges this narrative.

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).

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
