Concurrent resistance and endurance training influence basal metabolic rate in nondieting individuals

Open access

Abstract

Thirty physically active healthy men (20.1 ± 1.6 yr) were randomly assigned to participate for 10 wk in one of the following training groups: endurance trained (ET; 3 days/wk jogging and/or running), resistance trained (RT; 3 days/wk resistance training), or combined endurance and resistance trained (CT). Before and after training, basal metabolic rate (BMR), percent body fat (BF), maximal aerobic power, and one-repetition maximum for bench press and parallel squat were determined for each subject. Urinary urea nitrogen was determined pre-, mid-, and posttraining. BMR increased significantly from pre- to posttraining for RT (7,613 ± 968 to 8,090 ± 951 kJ/day) and CT (7,455 ± 964 to 7,802 ± 981 kJ/day) but not for ET (7,231 ± 554 to 7,029 ± 666 kJ/day). BF for CT (12.2 ± 3.5 to 8.7 ± 1.7%) was significantly reduced compared with RT (15.4 ± 2.7 to 14.0 ± 2.7%) and ET (11.8 ± 2.9 to 9.5 ± 1.7%). Maximal aerobic power increased significantly for ET (13%) but not RT (−0.2%) or CT (7%), whereas the improvements in one-repetition maximum bench press and parallel squat were greater in RT (24 and 23%, respectively) compared with CT (19 and 12%, respectively). Urinary urea nitrogen loss was greater in ET (14.6 ± 0.9 g/24 h) than in RT (11.7 ± 1.0 g/24 h) and CT (11.5 ± 1.0 g/24 h) at the end of 10 wk of training. These data indicate that, although RT alone will increase BMR and muscular strength, and ET alone will increase aerobic power and decrease BF, CT will provide all of these benefits but to a lesser magnitude than RT and ET after 10 wk of training.

TL;DR

In 30 nondieting, physically active young men, 10 weeks of resistance training or combined resistance-plus-endurance training raised basal metabolic rate, while endurance training alone lowered it. Combined training produced benefits across body composition, strength, and aerobic power, but generally to a smaller degree than the single-mode programs.

Key findings

  • BMR rose significantly in the resistance group (7,613 ± 968 to 8,090 ± 951 kJ/day) and combined group (7,455 ± 964 to 7,802 ± 981 kJ/day), but fell significantly in the endurance group (7,231 ± 554 to 7,029 ± 666 kJ/day); the resistance and combined changes did not differ significantly from each other.
  • Body fat decreased in all groups, with a larger reduction in the combined group (−3.5 ± 1.8%) than in resistance (−1.4 ± 0.1%) or endurance (−2.3 ± 1.2%). Fat-free mass increased in resistance (2.7 ± 0.4 kg) and combined (3.2 ± 0.9 kg) but decreased in endurance (−1.4 ± 0.9 kg).
  • Maximal aerobic power increased significantly only in the endurance group (13%); the combined group rose 7% but was not statistically significant from baseline, and resistance changed −0.2%. Strength gains were larger in resistance than combined: bench press 24% vs 12%, and squat 23% vs 19% in the results section.
  • Urinary urea nitrogen at 10 weeks was higher in endurance (14.6 ± 0.9 g/24 h) than in resistance (11.7 ± 1.0 g/24 h) or combined (11.5 ± 1.0 g/24 h). Across all groups, change in fat-free mass correlated with change in BMR (r = 0.74, P < 0.01).

Methods

  • Thirty healthy, physically active men (20.1 ± 1.6 yr) were randomly assigned to endurance training, resistance training, or combined training (n = 10 each) for 10 weeks, training 3 days/week on alternate days.
  • Before and after training, the study measured BMR by indirect calorimetry, body composition by hydrostatic weighing, maximal aerobic power by treadmill test, one-repetition maximum bench press and squat, urinary urea nitrogen, and 3-day dietary intake.
  • Analysis used one-way ANOVA on pre-to-post difference scores with Tukey post hoc tests, repeated-measures ANOVA for urinary urea nitrogen and diet, within-group t-tests, and Pearson correlation; significance was set at P ≤ 0.05.

Limitations

  • The paper does not explicitly list limitations. Evident limitations include the small sample of 30 young, physically active men, the short 10-week training period, and the absence of a nonexercising control group, which restrict generalizability and causal inference.
  • Diet was ad libitum; 3-day food diaries showed no significant changes, but self-reported intake may not fully capture energy balance or dietary compliance.
  • When BMR was normalized to fat-free mass, no group showed significant improvement, and the endurance group had a nonsignificant fat-free mass decline; the authors’ explanation linking BMR changes to fat-free mass changes is therefore partly speculative.

  • The paper relies on this without support.

    Before this study, no published work had tested how combined resistance and endurance training affects basal metabolic rate in people not dieting.

    “To our knowledge, no studies exist that have addressed the influence of concurrent resistance and endurance training on BMR in nondieting individuals.”
  • The paper relies on this without support.

    Many people take part in combined resistance and endurance training, but little is known about how this training affects metabolic rate.

    “Many individuals participate in concurrent resistance-and endurance-training programs, yet limited information is known about the effect of this type of training on metabolic rate.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-02, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-02 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
