Supersets do not change energy expenditure during strength training sessions in physically active individuals

Background/Objective: The energy expenditure (EE) in strength training (ST) is analyzed both during and after each training session. However, little information exists about the influence of strength exercises supersets on EE. We aimed to determine whether supersets of ST exercises influenced EE during and after one strength exercise session. Methods: Twenty men were randomly divided to perform either a session with grouped exercises for the same muscle (GE: 26.6 +/- 3.4 years; 17.4 +/- 3.4 body fat) or a session with separated exercises (SE: 24.9 +/- 2.6 years; 15.4 +/- 5.9 body fat). Four exercises (5 sets of 8-10 maximum repetitions) for knee extensor muscles and shoulder horizontal flexor muscles were executed in both training sessions. The EE of each experimental session was obtained through the analysis of oxygen uptake during and after exercise (60 minutes postsession). Results: Total work during the session and increases in lactate concentrations were similar between the GE and SE Groups. During exercise, EE was greater in the SE Group when compared with the GE Group (GE: 123.8 +/- 14.36 kcal vs. SE: 131.77 +/- 20.91 kcal). During the postexercise period, GE induced greater EE when compared with SE (GE: 25.12 +/- 7.86 kcal vs. SE: 19.76 +/- 5.53 kcal). However, the exercise sequence did not influence overall EE (GE: 148.92 +/- 18.72 kcal vs. SE: 151.53 +/- 17.97 kcal, p = 0.920). Conclusion: Our findings indicate that, in physically active men, ST supersets do not influence total EE during and 60 minutes after a single session.
