Home-based Training in Obese Individuals (FITOB)

Effects of a Home-based Quality of Movement Protocol on Functional Movement, Postural Control and Muscular Strength in Obese Subjects

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.

6-week-home-based training protocols designed to improve general fitness levels and postural control performed in a circuit-training mode (time of work per set 30 s, time of rest between each exercise 15 s, time of rest between sets 2 min, total volume 3 sets) for a duration of 45 min with a frequency of 3 days per week while performing mobility, stability and motor control exercises.

Functional performance using the Functional Movement Screen protocol in arbitrary units with a 0-12 point scale in which higher scores mean a better outcome

Body stability using the modified version of the Balance Error Scoring System protocol in arbitrary units with a 0-30 point scale in which lower scores mean a better outcome

Breathing pattern performance using the Total Faulty Breathing Scale protocol in arbitrary units with a 0-12 point scale in which lower scores mean a better outcome
