Hamstring “Tantrums”: Effective Exercise or Social Media Noise?
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.

A Rationale for Progressing Whole-Body Isometric Training Through Isometric Strength Endurance Using PIMA
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.

Hamstrings Behaviour and Movement Expression: the Great Debate
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.

Why Stability and Precision Govern Injury Prevention and Performance in Athletes
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.

Introducing the Power Carriers of Human Performance

Fine-tuning the Sacroiliac Joint for Sport Performance
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).

Three (at least) Reasons Why You Should Care About Foot Performance
Every coach who really trains athletes on a daily basis and really knows the discriminants of human performance is aware of the fact that building the “perfect” performance machine is not a question of one single detail respect to others. Sports performance is a delicate balance between several aspects converging into one main goal: it’s the whole body synchrony merging into one specific output. Unfortunately social marketing is king today and some coaches, instead of showing

Learning to Land
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

A Neurological Approach to Injury Rehabilitation
Whether you are recovering from an injury or looking to upgrade your athletic performance, one major key to success lies in the nervous system. The nervous system, including the brain, is a major influence on the function of the body. It directly controls cognitive and athletic performance, hormonal releases, energy levels, organ function, and the processes of healing and recovery. One particularly interesting quality of the brain is that it spends a lot of energy limiting us

Stretch and Strenghten your Foot/Ankle Complex with the Dorsiflex
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

Reconsidering the Seated Good Morning for Hamstrings and Low-Back Health
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

Is Blood Flow Restriction Training for Real or Just Another Fitness Fad?
For almost 20 years I have been helping people overcome pain with manual therapy and using exercise to help them improve functional capacity. I have found it very easy to perform manipulation, tooling, needling, taping (among other modalities) to help alleviate pain. But as a clinician I have the responsibility to include active therapy (exercise) whenever possible. My belief is manual therapy is the bridge to help people be more active and exercise more. The difficult part f

Elite Player Profile Part II: You've Completed your Assessments, Now What?
Once you’ve designed your elite player profile and completed the assessment process with your athletes, it’s time to use the data to drive your decision making. The priority should always be managing injury risk, and this data is extremely valuable to identify your high risk athletes. These are athletes who performed below the minimum standard on a number of assessments, and should be managed differently than your athletes who performed above the minimum standard. I have crea

The Lost Art of Creating the Elite Player Profile
In any high performance environment the goal is clear, minimize the risk of injury and maximize athletic development. If you lay in bed at night and honestly tell yourself you’ve done everything in your control to protect your athletes health, then you certainly have an assessment process in place. Most sports have technical, tactical, and physiological (I suppose we could add psychological here, but we won’t for now) requirements. If you don’t work with elite level athletes,

Importance of Optimizing Hip Mobility in Elite and Professional Athletes
The hip (femoroacetabular) joint is arguably the most important joint in the human body as it relates to biomechanics of athletic performance. In every sport in the world, one hip joint may be called upon to perform quick, powerful and oftentimes violent movements while the other hip provides the necessary coordinated stability around which these movements can occur. There are 29 different muscles that are working in synergy to create effective movements around the hip joint.

The Physics of Inertial Training
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
