Influence of Sex on the Recovery Response Following Isometric Exercise Performed at Long Muscle Length.
Article in Journal of strength and conditioning research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
abstractRosaci, G, Nigro, F, Marcora, SM, and Bartolomei, S. Influence of sex on the recovery response following isometric exercise performed at long muscle length. J Strength Cond Res 40(10): e1039-e1045, 2026-The aim of the study was to compare the recovery responses of the pectoralis major muscle in men and women after isometric exercise. Twelve men (age: 25.3 ± 4.1 years; height: 177.6 ± 7.4 cm; body mass: 81.6 ± 10.1; training experience: 6.7 ± 3.7) and 10 women (age: 24.5 ± 1.4 years; height: 166.4 ± 6.7 cm; body mass: 62.5 ± 7.4; training experience: 5.0 ± 2.7) performed a high-intensity (maximum effort) intermittent isometric exercise at long muscle length (LML) for the pectoralis major muscle. Peak force at LML and short muscle length, average power at bench throw power test, muscle architecture (muscle thickness and corrected echo intensity), and muscle soreness were assessed before, and 15 minutes, 24 and 48 hours postexercise. Rate of perceived exertion was also collected 15 minutes postexercise. Although men were significantly stronger that women, no sex differences were detected in changes of peak force at LML ( p ≥ 0.184) and short muscle length ( p ≥ 0.514), muscle architecture ( p ≥ 0.552), soreness ( p ≥ 0.09), and on rate of perceived exertion ( p ≥ 0.452). However, a greater drop in average power at the bench throw power test was registered in men compared with women 15 minutes postexercise ( p < 0.001, d = 2.36). Although similar patterns of muscle recovery were observed in men and women, a sex-related difference may exist in the acute effects of isometric exercise on power exertion. Men indeed may be more sensitive to acute fatigue and more prone to power reductions after isometric exercise.
