The kettlebell is beneficial for strengthening muscles and improving cardiovascular capacity, however, the use of the kettlebell often relies on explosive exercises that require good technical skills. Is this type of training suitable for seniors?
Resistance training is often associated with the consumption of protein supplements. The main goal is to optimize the effects of training on muscle strength and mass. But is it really the case?
Current official recommendations include moderate to high intensity weight training (50-80% of 1RM), targeting large muscle groups, at least twice a week but how do we know the impact of load intensity on hypertension?
Regular resistance training increases and maintains muscle strength and mass. But does it have an impact on the risk of non-communicable diseases? What is the optimal dose of weight training to achieve significant health gains? And can we expect additional benefits from combining resistance training with cardiovascular endurance activity?
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 ?
