What does this research mean for the field?

A bodyweight circuit performed prior to self-paced interval training significantly impairs running performance and reduces exercise readiness, regardless of sex. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To investigate the acute effects of a bodyweight circuit on self-paced interval running performance, perceptual responses, and physiological markers in male and female runners.

August 30, 2026Sport Sciences for HealthOpen Access

A pre-training bodyweight circuit impairs interval running performance, increasing total time by ~15 seconds.

Q: What is the clinical evidence from this study?

Study design: RCT. Population: Recreational endurance runners (n=16). Intervention: Bodyweight circuit training vs. Control condition (no bodyweight exercises). Primary outcome: Total time for 8 × 200 m self-paced interval training (p=<0.01).

Why the study?

The acute effects of a bodyweight circuit on self-paced interval training performance, and whether these effects differ by sex, remained unclear.

Does a preceding bodyweight circuit acutely impair self-paced interval running performance in male and female runners?

Comparison

Interval training preceded by a bodyweight circuit vs a control condition

Design

Randomized, counterbalanced crossover trial

Key result

A bodyweight circuit performed prior to self-paced interval training significantly impaired running performance, increasing total time from 325.1 to 339.9 seconds, regardless of sex.

Overview

Runners should avoid bodyweight circuits immediately before intervals to preserve performance; extends acute interference evidence to self-paced training in recreational athletes.

Key Points

To investigate the acute effects of a bodyweight circuit on self-paced interval running performance, perceptual responses, and physiological markers in male and female runners.
Randomized, counterbalanced crossover trial involving 16 runners (8 men, 8 women).
Participants completed two interval training sessions (8 × 200 m with 90 s recovery): a control condition and an experimental condition preceded by a bodyweight circuit (4 exercises, 3 sets of 15 s work and 45 s rest).
Assessed exercise readiness on a 10-point scale, interval running completion times, heart rate, and rating of perceived exertion.
Prior bodyweight circuit significantly impaired total interval running completion time compared to control (339.9 ± 51.2 s vs. 325.1 ± 52.1 s, p < 0.01), with no significant interaction by sex (p > 0.05).
Readiness for interval training was significantly reduced following the bodyweight circuit compared to control (5.8 ± 2.2 vs. 7.5 ± 2.0 a.u., p < 0.05).
Heart rate and rating of perceived exertion during the intervals did not differ significantly between conditions (p > 0.05).

Does a preceding bodyweight circuit acutely impair self-paced interval running performance in male and female runners?

Population

16 recreational endurance runners (50% female, mean age ~24.5 years) with at least 6 months of training experience, evaluated in a randomized crossover design for acute performance effects.

Intervention

Bodyweight (BW) circuit consisting of four exercises (countermovement jumps, alternating lunges, sit-ups, burpees) performed for three sets of 15 s of work and 45 s rest, immediately preceding a self-paced interval training (ITSP) session (8 x 200 m with 90 s recovery).

Comparator

Control condition consisting of an identical warm-up and two 50-m sprints, but without the bodyweight exercises, prior to the self-paced interval training session.

Outcome

Self-paced interval training performance (total time and mean time per repetition) and perceptual/physiological responses (readiness, heart rate, rating of perceived exertion).surrogate

Main Result

Absolute Event Rate: 339.9% vs 325.1%

p-value: p=<0.01

Performing a high-intensity bodyweight circuit immediately before self-paced interval training acutely impairs running performance by approximately 5% in both male and female recreational runners.

Limitations

Absence of a specific familiarization period for the self-paced approach
Lack of direct fatigue metrics following the bodyweight exercises
Explicit assessment of perceived readiness prior to the interval training may have inadvertently influenced participants' performance expectations
Lack of direct fatigue metrics following the bodyweight exercises to isolate the cause of performance decline.
