Partial Range, Full Gains? The Effect of 8 Weeks of Partial Range of Motion Training at Long Muscle Lengths on Elbow Flexor Hypertrophy and Strength in Trained Individuals.

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
We investigated the effects of initial partial range of motion (pROMinitial; 0°-70°) and full range of motion (fROM; 0°-140°) training on elbow flexor hypertrophy and strength in resistance-trained individuals. Thirteen individuals (males: n = 11, 26.6 ± 4.0 years, 89.2 ± 16.7 kg, and 183.3 ± 10.0 cm; females: n = 2, 24.0 ± 1.4 years, 75.5 ± 12.3 kg, and 168.0 ± 4.2 cm) completed a randomized within-subject study, performing unilateral preacher curls with each arm assigned to one condition over 8 weeks. Muscle thickness at 50% and 70% of the distance between the acromion and cubital fossa, maximal voluntary contraction (MVC) at elbow angles of 40° and 100°, and one-repetition maximum (1RM) were measured pre- and postintervention. Bayesian analyses were employed to infer effects from posterior distributions. Results showed similar improvements in muscle thickness at 50% humeral length between conditions, whereas pROMinitial exhibited trivial to small superiority at 70% elbow flexor length (standardized mean difference [SMD] = 0.10 and Bayes factor = 4.87). Additionally, MVC at 100° (SMD = 0.24 and Bayes factor = 3.02) and 1RM (SMD = 0.17 and Bayes factor = 1.95) demonstrated greater but negligible improvements with fROM, with weak to moderate evidence supporting the hypothesis of differential effectiveness across interventions. These findings suggest that pROMinitial may offer modest benefits for regional hypertrophy, particularly at longer muscle lengths. The results indicate that both training modalities can induce beneficial adaptations, with pROMinitial offering slight advantages in specific contexts. CLINICAL
