Comparing full-body flywheel eccentric protocols: cluster set vs. traditional training on muscle damage, arterial stiffness, jump performance, grip strength, cognitive, and perceptual responses.

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
The study investigated the acute effects of traditional (TRAD) and cluster (CLUS) set full-body flywheel eccentric exercise (FW) protocols on muscular performance, damage, vascular responses, and cognitive function. Twenty-four well trained male team sport athletes participated in this randomized controlled trial. Participants were randomly assigned to TRAD or CLUS FW protocols. FW protocols consisted of four sets of eight repetitions for four exercises (squat, high pull, bent over row, and calf raise), with 120 seconds of rest between sets. Measured variables included creatine kinase (CK), muscle soreness, muscle and tendon stiffness, countermovement jump (CMJ), handgrip strength, blood pressure, cardio-ankle vascular index (CAVI), anklebrachial index (ABI), heart rate, cognitive function, and fatigue. These assessments were conducted pre-exercise, immediately post-exercise, and at 24 h and 48 h post-exercise. Both protocols showed similar power outputs and cognitive improvement over time (p < .05). Handgrip strength declined in both groups, while perceived fatigue and muscle soreness increased (p < .05). However, the CLUS exhibited lower CK levels, lower quadriceps stiffness at 24 and 48 h post-exercise, and lower patellar tendon stiffness immediately post-exercise, compared to the TRAD (p < .05). Greater vascular fluctuations, particularly in diastolic blood pressure (DBP) and CAVI, were observed in the TRAD group (p < .05). These findings suggest that a cluster set protocol for full-body flywheel eccentric exercise may be advantageous for recovery compared to a traditional set protocol in well trained male team sport athletes.
