Strength Training: aspetti teorici, metolodogici e didattici

The last decade is well rooted in the idea of ​​increasing the muscular fitness to improve health. High levels of muscular strength are associated with cardiometabolic risk profile significantly lower at lower risk of mortality in general and CVD events, with a lower risk of experiencing functional limitations and non-lethal diseases. Currently there are insufficient data on the prediction type of dose-response relationship between muscle and finess health or the existence of a threshold "beneficial" recommending that a minimum level of muscular strength, power or resistance related to health. Beyond having increased strength, involved several positive changes in health-related biomarkers that may be associated with a regular performance of resistance training, such as improving body composition of blood glucose levels, insulin sensitivity and blood pressure in people already suffering from hypertension or to the first stage of hypertension. Similarly, resistance training may be effective in the prevention and treatment of "metabolic syndrome". Equally important is the fact that the exercise which promotes the strength and muscle mass effectively increases the bone mass (density and content) and the resistance of those bones specifically subjected to stress and can represent a valid means to prevent, slow down or even reverse the loss of bone mass in people with osteoporosis. Given that muscle weakness is identified as a risk factor osteo-artritico/artrosico, strength training can reduce the likelihood of developing musculoskeletal diseases. In people with osteo-artrite/artrosi the weight training can reduce pain and disability. The benefits mental health resulting muscle workout has been paid less attention than those arising from the exercise cardiorespiratory. Preliminary work suggests that resistance training can prevent or ameliorate depression and anxiety, increase levels of "energy" and reduce fatigue.
