Recovery, like loading, should be a deliberate process with physiological targets. And the most important place to start is not the muscle. It is the brain. The brain consumes over 20% of the body's total energy at any given moment. Roughly 50% of that is dedicated to oculomotor function and visual processing. These are not abstract statistics — they carry direct implications for how we think about fatigue, fuel delivery, and the recovery strategies we apply.

Heart rate variability (HRV) has become a widely adopted tool in sport science and athlete monitoring, often interpreted as a straightforward indicator of recovery status. In many applied settings, higher HRV values are assumed to reflect better recovery, greater readiness, and a more favourable autonomic state. Conversely, lower HRV values are frequently interpreted as signs of fatigue, stress, or insufficient recovery.

HRV is not a magical window into the entire autonomic nervous system, nor a universal indicator of stress or fatigue. It is a specific cardiac signal, reflecting how the heart is being regulated at a given moment. And if we want HRV to remain a meaningful tool in sport, we need to move beyond outdated concepts and adopt a more accurate, nuanced understanding of what the signal actually represents.

Human movement is not simply the product of muscular contractions or joint mechanics. It emerges from a dynamic interplay between the central nervous system (CNS) and the autonomic nervous system (ANS), where cognition, emotion, and physiology converge to shape how an athlete prepares, executes, and adapts movement. If we want to optimize performance beyond biomechanics, we have to engage with how the body regulates its own internal state.

In contemporary sport, the word “recovery” is sometimes used so casually that it has almost lost its meaning. Athletes and practitioners repeat that recovery is essential, yet the practical interpretation often collapses into a narrow set of routines—usually a foam roller, a massage gun, or a cold plunge. This reductionist view is incompatible with the complexity of human physiology.

If you’ve had issues with hydration or cramp in the past and have gone online looking for a solution then the chances are that you’ve seen the term ‘sweat test’ mentioned. In this piece i will explain just what a ‘sweat test’ is, what the options are and how taking one could help you significantly improve your performance. First, Why do Humans Sweat so Much? Here’s a pub-quiz-worthy fact for you, humans sweat considerably more than any other animal on earth. Our sweat rate

A few years ago, during our MSc studies in the Netherlands, we experienced what profound effect the lack of light can have on our bodies, energy levels and mood. After doing extensive research on the topic, we found out that light therapy is a fantastic solution to help us feel more energetic during the dark and gloomy winter days. We experimented with numerous products on the market (light boxes and visors) and realized that there was a need for a light therapy product, whic
