Healthy Activity

Physical fitness is not only one of the most important keys to a healthy body, it is the basis of dynamic and creative intellectual activity.

John F. Kennedy

One of the key drivers of cardiorespiratory fitness is how active we are. For many, moving from little to some physical activity is one of the most impactful changes towards getting healthier. Meeting the minimum levels recommended by physical activity guidelines is enough to significantly reduce risks of cardiovascular disease, such as heart attacks, strokes and high blood pressure, as well as diabetes, dementia, some forms of cancer, such as bowel, prostate and breast cancer, and also mental health conditions such as depression [1]. These conditions, collectively known as "non-communicable disease", account for up to 89% of deaths in the UK [2]. What is increasingly recognised also, is that being too sedentary is bad for our heath too, regardless of how active we are [3].

Being optimally active, we can reduce risks of these chronic diseases over time but also more immediately, we can improve sleep on multiple levels, from the total duration we sleep, how long it takes us to get off to sleep, as well as sleep quality [4]. Even a single session of being active, whether that's walking or other activities, is enough to improve our brain function [5].

On an individual basis, it is possible to identify which form of physical activity would give the greatest results in the most efficient programme. Cardiopulmonary exercise testing (CPET) assessments are able to look at how well our whole-body systems work and thus whether our heart, lungs or metabolism might be our individual limiting factor.

For those those individuals who are already highly active and train regularly, optimal recovery can sometimes be the critical limiting factor to performance. Being able to objectively track this with wearable tech means being able to work smarter and adapt training on the go to make the most from each and every session.
