Although HIIT circuits combine cardiovascular and neuromuscular demands, it is not yet clear what the real fitness and health benefits are for practitioners.
SIRT1 may play a crucial role in telomere protection. Some studies have shown that Master athletes have higher levels of SIRT1 than their sedentary counterparts. But is there a link between SIRT1 levels, insulin secretion and telomere length?
In addition to the pharmacological treatments, physical activity (endurance or muscle strengthening) is often recommended for the prevention, treatment and control of high blood pressure. But how effective is isometric training in reducing blood pressure ?
Because it would allow the complete recruitment of high-treshold motor units, training until muscle failure often appears to be an ideal solution for maximising gains. However, with the same volume of training, what are the benefits with light and heavy loads ?
Sleep is essential to our proper functioning, both physiologically and psychologically. For an adult, it is generally recommended to sleep between 7 and 9 hours per night. However, these guidelines are very broad and do not consider the inter-individual differences in the sleep needs of each athlete.
Arterial stiffness is an independent risk factor for the development of cardiovascular disease, associated with an increased risk of mortality. If general physical activity seems to reduce it, what about resistance training?
Depression affects approximately 280 million people worldwide. Physical activity is often prescribed for depressed people with moderate to large benefits depending on the study. But could physical activity act as a preventive measure and reduce the risk of developing depression?
In addition to strength and muscle gains, resistance training induces muscular and nervous fatigue. It is often said and written that it is more difficult and longer to recover nervously than muscularly. But is this really the case?
