Muñoz Pinto, Enrique
Background and objective: Concurrent training, defined as the combination of two or more physical qualities that are practiced in the same session (intra-session), same day (inter-session) or on alternate days (intra-microcycle), has shown different benefits of physical condition Health Related (CFRS); in the domains of muscular strength, aerobic capacity, body composition and physical well-being in general. However, although they have been written innumerable benefits in physical and mental health. The objective of this research was to evaluate the effects of concurrent training about physical condition and body composition in a cohort of physically inactive adults from the city of Bogotá. Methods: This is an uncontrolled clinical study in 30 subjects between 18 and 45 years of age. both sexes, apparently healthy and physically inactive. The intervention consisted of 36 supervised training sessions, with a frequency of three days / week, with sessions of 1h / day, applying the Orangetheory Fitness Training Program (OFT) ™ Results: we observe changes statistically significant in the indicators waist circumference (-2.3 cm), fat mass (-1.15 kg) and mass lean (+0.96 kg). In the muscular and aerobic component, significant increases were observed in all the variables studied (prehensile force +4 kg, long jump +11 cm, jump vertical +5 cm, 1-RM squat +18 kg, 1-RM press bench +3 kg, and VO2max +6.7 ml / kg / min), P <0.05. These results are accompanied by the improvement of the estimated flexibility with the test of sit and each (+ 3.9 cm), P <0.001. Conclusions: 12 weeks of training concurrent with high intensity intervals on alternate days, produces capacity improvements aerobic, muscular strength, flexibility and modifies some anthropometric parameters and body composition in physically inactive population.
