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.

Abstract
backgroundThis study investigated the effects of adding blood flow restriction (BFR) to high-load isokinetic resistance training on muscle strength and local muscular endurance.
methodsForty-two middle- and long-distance runners were randomly assigned to an isokinetic training group with BFR (BFR group; n = 21) or an isokinetic training group without BFR (non-BFR group; n = 21). The training protocol consisted of concentric knee flexion and extension exercises performed at angular velocities of 60°/s (3 sets of 10 maximal repetitions) and 180°/s (3 sets of 30 maximal repetitions), twice weekly for 8 weeks. BFR was applied at 80% of arterial occlusion pressure (AOP) in the BFR group. Muscle strength (peak torque [PT]) and local muscular endurance (fatigue index [FI]) were evaluated before and after the intervention.
resultsBoth groups demonstrated significant increases in muscle strength for both knee flexors and extensors at angular velocities of 60°/s and 180°/s. However, no significant between-group differences were observed for strength gains (p > 0.05 for all comparisons). Regarding local muscular endurance, the magnitude of improvement in FI was significantly greater in the BFR group compared to the non-BFR group for both flexors (p = 0.003, η²= 0.102) and extensors (p = 0.005, η²= 0.091).
conclusionsThis study demonstrates that adding BFR to high-load isokinetic resistance training does not enhance muscle strength beyond high-load isokinetic resistance training but significantly improves local muscular endurance, as evidenced by greater reductions in FI in the BFR group. These findings suggest that BFR may be a valuable tool for optimizing endurance-specific adaptations in athletic populations requiring sustained performance. Future research should explore optimal BFR protocols for endurance-focused training across diverse athletic disciplines.
