Effect of combined sprint interval training and resistance training on psychophysiological outcomes in women at risk for metabolic syndrome

Abstract Purpose Psychological stress, psychological distress and mental well-being are related to metabolic syndrome (MetS) risk factors. Exercise is beneficial for both MetS and mental health independently; however, combining sprint interval and resistance training has been insufficiently studied for its potential to simultaneously address both physical and psychological outcomes. The purpose of this intervention was to examine how sprint interval training and resistance training impacted MetS outcomes, perceived stress, psychological distress and well-being. Methods 40 participants (M age = 44.59 ± 9.24 years, weight = 197.25 ± 44.07 kg, height = 1.65 ± 0.07 m) were recruited to begin a 10-week sprint interval training and resistance training study consisting of resistance training and sprint interval training. Participants were assessed for MetS outcomes (blood pressure, waist circumference, triglycerides, high-density lipoprotein, and fasting blood glucose) and psychological outcomes (well-being, perceived stress, anxiety, depression and anger). Results Waist circumference ( t (36) = 3.18, p = .002), systolic blood pressure ( t (36) = 2.81, p = .004), diastolic blood pressure ( t (36) = 2.85, p = .004) and triglycerides ( t (36) = 2.04, p = .024) showed a significant decrease from pre- to posttest. A significant increase was noted for psychological well-being ( t( 36) = 2.18, p = .03). Conclusions These findings support the utility of high-intensity concurrent training in improving both physical and psychological health in individuals with MetS risk factors.
