Data on the impact of physical exercise treatment on depression and anxiety in a psychiatric hospital for adolescents

Muscle Quality Index is inversely associated with psychosocial variables among Chilean adolescents

“…Based on the described antecedents, it has been evidenced that an increase in muscular strength decreases psychosocial variables [ 12 , 19 , 45 ]. In this context, it is understood that a higher level of strength would generate a higher MQI [ 20 – 22 , 43 ]. Therefore, there should be a direct and inverse relationship between MQI and psychosocial variables.…”

“…In this sense, an alteration in these psychosocial variables has been associated with decreased academic performance, increased drug use and consumption, a higher prevalence of suicidal ideation [39], and a decrease in sports practice [13,14]. In this line, recent meta-analyses have demonstrated the benefits of physical exercise on the levels of anxiety, stress, and depression [12,17,18], as well as the inverse association between high levels of physical fitness and low levels of psychosocial disorders [40][41][42][43][44]. In this context, scientific evidence has focused mainly on aerobic training and cardiorespiratory capacity as a modulator of psychosocial variables [18,41,43].…”

In parallel, the effects of strength training, its association with MQI, and its consequent impact on psychosocial variables are scarce [12].…”
