For more than 120 years, over-the-counter orthotics have been built around a single idea: control excessive pronation by propping up the medial longitudinal arch. The reasoning seemed obvious — if a collapsing arch drives the foot into pronation, then supporting that arch should stop it. The problem is that recent research has quietly dismantled this assumption.

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.

In the elite environment, strength training isn’t an optional add‑on; it’s a non‑negotiable pillar of performance. Treating the weight room as secondary to the pitch reflects a deep misunderstanding of modern sports science. This isn’t about random lifting sessions — it’s about building a system where every rep has a purpose and contributes to what happens on match day.

Human movement is a complex, adaptive system. Every action—whether a maximal sprint, a change of direction, or a technical skill—emerges from the interaction of multiple subsystems: musculoskeletal, neural, perceptual, and environmental. Within this landscape, the trunk plays a central integrative role. It is not simply a structure that stabilizes or resists motion; it is a dynamic hub that modulates force, coordinates segments, and adapts to changing constraints.

For more than two decades, core stability has been one of the most widely used concepts in sport science and rehabilitation. It appears in clinical assessments, warm‑ups, physiotherapy prescriptions, and performance programs. It is invoked to explain pain, prevent injury, and enhance athletic performance. Yet the more closely we look at the origins of the idea, the less coherent it becomes.

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.

Given the intense repetitive stress of competition, the wear and tear of chronic pathologies, and the increasing physical demands on young athletes, isometrics in all forms are essential for both development and durability. Far from being "static" in progress, isometric work is a powerful driver for transferring strength into sport-specific dynamic movements.

Isometric training is often discussed as a single method, but this framing obscures the critical distinctions between how isometric force is produced and why those distinctions matter for performance, durability, and health. This article outlines the rationale for progressing isometric training through Isometric Strength Endurance using Pushing Isometric Muscle Actions (PIMA) at longer contraction durations (45 seconds) and maximum descending intensity across the whole body.

Foot strengthening exercises are inexpensive, easy to perform, and result in significantly better outcomes.

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.

Most athletes don’t struggle because they lack effort. They train hard, often in demanding environments that introduce fatigue, complexity, and variability by design. Those demands are part of sport. Yet the injuries that interrupt seasons—and the performance plateaus that quietly precede them—tend to appear long before competition intensity peaks.

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). Re

Life is healthy feet. Anyone who has suffered from a foot injury can attest to how quality of life is ruined by unhealthy feet. The foot is the only part of the body to regularly contact the ground. Comprised of 26 bones, 33 joints, 19 muscles, 107 ligaments, 10 tendons, the foot is arguably the most mechanically complex part of the body - so much so that Leonardo da Vinci called the foot a work of art. Generally, the properly functioning foot needs 30° of inversion, 20° of e

When it comes to low-back strength and posterior chain development in athletic performance, no exercise has the characteristics of the seated good morning. This exercise has been used for several years by Soviet Union weightlifters in the 70's and 80's and it was an integral part of their training regime. Legendary weightlifting coach Alexei Medvedyev, in his book A System of Multi-Year Training in Weightlifting , wrote that "seated good mornings on a bench and on the floor

For an optimal understanding of how inertial machines work, the first important step to take is to have a clear knowledge of the basic physics principles behind the concept of inertial training. This is fundamental since not having a basic knowledge in physics will lead us to erroneous conclusions as well as doing wrong comparisons between different types of equipments. Inertial (or flywheel ) machines work under the principle of the accelerated Uniform Circular Motion, which
