Bioceramic arm garment does not increase diameter of brachial artery and blood flow-Compliance and biceps microcirculation in male recreational sports practitioners at rest: A single blinded randomized cross-over study.
Article in Journal of sport and health science, 2025. 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
backgroundInterest in clothing that reflects far infrared (FIR) radiation naturally emitted by the body during and after exercise has increased based on the assumption that this can increase arterial and venous blood flow. Indeed, in vitro and animal model research seems to report promising effects of FIR on the nitric oxide pathway and microcirculation. However, to date, there are no well controlled studies investigating the effect of FIR garments on resting microvascular and macrovascular function in humans. Thus, the aim of this study was to examine the acute effects of wearing FIR arm garments on vascular function.
methodsThirty-one male recreational sport practitioners (4.9 ± 3.3 h of sport/week; 32.1 ± 9.5 years; 178.6 ± 7.9 cm; 74.1 ± 11.2 kg; 23.2 ± 2.5 kg/m
resultsThe main results were that at all time points, compared to placebo, FIR did not significantly affect brachial artery diameter and blood flow, CR-PWV, or total hemoglobin (condition × time interaction: p = 0.22, 0.54, 0.51, 0.96, respectively). Moreover, no significant condition × time × sensor position interaction effect was found in skin temperature (p = 0.99). However, pressure under garment was significantly higher under the FIR condition compared to placebo (+53%, p = 0.01, 95% confidence interval: FIR: 1.64-2.92 mmHg; placebo: 0.88-2.14 mmHg) while microvascular parameters were unchanged.
conclusionContrary to our hypothesis, wearing an FIR arm garment at rest does not lead to an improvement of either macro or microvascular function. These results suggest limited benefits in the sports context, notably during recovery.
