Physical activity is defined as 'any bodily movement produced by skeletal muscles that results in an energy expenditure greater than that of the resting metabolism'. Physical activity includes 'activities of daily living, physical exercise and sporting activities'. The scientific community is agreed in recognising the benefits of physical activity, both in healthy individuals and in those suffering from chronic diseases. With this in mind, the law of 2 March 2022 allows doctors to prescribe Adapted Physical Activity. In the case of chronic renal failure, there are a number of factors that can limit physical activity in haemodialysis patients, such as anaemia, nutritional status and post-dialysis fatigue. However, the risks associated with a sedentary lifestyle play a role in the development of chronic disease, in particular hypertension and diabetes. The benefits of physical activity have been widely identified in chronic renal failure, particularly in terms of cardiovascular and muscular function. More generally, physical activity has a positive impact on physical, psychological and social quality of life (increase in overall quality of life score, improved sleep, reduced pain, etc.). Physical activity should therefore be encouraged in patients with chronic renal failure, whether on dialysis or not, whatever their age. The aim of this study is to assess whether individualised support (from an advanced practice nurse and an adapted physical activity teacher) improves the practice of physical activity at home in patients who have been on haemodialysis for less than a year, and whether this improvement is sustainable over time.
