Acute Cardiopulmonary Responses of Women during Exercises of Localized Muscular Resistance and Aerobic Exercises in the Same Energy Demand. JEPonline 2018;21 (4):123-133. The aim of this study was to compare the differences in acute cardiopulmonary responses between the localized muscular resistance (LMR) exercises and the aerobic exercises performed in the same energy demand in young women. Nine healthy women (with a mean age of 22.33 [+ or -] 3.57 yrs; weight, 63.26 [+ or -] 7.46 kg; height, 1.67 [+ or -] 0.07 m; and body mass index of 22.71 [+ or -] 1.37 kg*[m.sup.-2]) were enrolled. Protocol consisted of a maximum cardiopulmonary test and a maximum repetition test with a 24-hr interval. After 48 to 96 hrs, they performed LMR exercises with 25 to 30 reps in the bench press, free squatting, and arm curl with a constant recording of cardiorespiratory variables and heart rate. After 48 to 72 hrs the aerobic exercise was performed. It consisted of treadmill walking for 20 min at the same oxygen uptake (V[O.sub.2]) as the LMR exercises. The LMR exercise obtained higher values for heart rate (HR) and pulmonary ventilation ([V.sub.E]) than the aerobic exercise, respectively, 129.01 [+ or -] 10.93 beats*[min.sup.-1] and 94.13 [+ or -] 7.48 beats*[min.sup.-1] (P<0.01) and 22.5 [+ or -] 4.01 L*[min.sup.-1] and 15.58 [+ or -] 2.48 L*[min.sup.-1] (P[less than or equal to]0.05). It was concluded that the LMR exercises resulted in greater chronotropic and ventilatory responses at the same aerobic energy demand, although with an insufficient overload to generate improvement in the subjects' cardiorespiratory fitness.
