Home-based Training in Obese Individuals

Study Overview
=================
Brief Summary
-----------------
Generally, the enhancement of physical fitness depends on the optimal modulation of different physiological, technical or psychological stimuli and within the factors the would contribute to a decrease performance level, obesity is one of them. In this context, ample evidence shows that obesity is associated with an augmented cardio-metabolic risk, lowered postural control, functional performance and strength-related variables. International guidelines suggests to counteract obesity to respect a minimum dosage of 150 min a week of physical activity at moderate intensity performed with resistance training exercises with a frequency of 2-3 days/week. However, in the aforementioned guidelines there is a little consideration for what concern the quality of motor execution (i.e., how an individual performs each movement pattern). In addition, the available literature demonstrates the effectiveness of a movement-quality training intervention on fitness parameters and postural control, compared to a mere conventional exercise, in normal-weight individuals . In account to this, the purpose is to evaluate whether a quality of movement protocol would be more effective than a traditional strength training exercise in improving postural control and fitness parameters in subjects with obesity.
