Abstract

Background

The benefits of exercise are well established but one major barrier for many is time. It has been proposed that short period resistance training (RT) could play a role in weight control by increasing resting energy expenditure (REE) but the effects of different kinds of RT has not been widely reported.

Methods

We tested the acute effects of high-intensity interval resistance training (HIRT) vs. traditional resistance training (TT) on REE and respiratory ratio (RR) at 22 hours post-exercise. In two separate sessions, seventeen trained males carried out HIRT and TT protocols. The HIRT technique consists of: 6 repetitions, 20 seconds rest, 2/3 repetitions, 20 secs rest, 2/3 repetitions with 2^′30″ rest between sets, three exercises for a total of 7 sets. TT consisted of eight exercises of 4 sets of 8–12 repetitions with one/two minutes rest with a total amount of 32 sets. We measured basal REE and RR (TT₀ and HIRT₀) and 22 hours after the training session (TT₂₂ and HIRT₂₂).

Results

HIRT showed a greater significant increase (p < 0.001) in REE at 22 hours compared to TT (HIRT₂₂ 2362 ± 118 Kcal/d vs TT₂₂ 1999 ± 88 Kcal/d). RR at HIRT₂₂ was significantly lower (0.798 ± 0.010) compared to both HIRT₀ (0.827 ± 0.006) and TT₂₂ (0.822 ± 0.008).

Conclusions

Our data suggest that shorter HIRT sessions may increase REE after exercise to a greater extent than TT and may reduce RR hence improving fat oxidation. The shorter exercise time commitment may help to reduce one major barrier to exercise.
