This research introduces a sustainable, thread-based wearable device that measures lactate in sweat using chemiluminescence. By transforming cotton thread into a low-cost analytical tool, it enables simple, smartphone-based monitoring of physiological changes, offering an eco-friendly alternative to conventional biosensors for sports and health applications.

This research examined whether mental imagery training enhances neural efficiency and performance in basketball free throws. A single imagery session didn’t change EEG activity or performance overall, but higher confidence improved outcomes. Findings suggest imagery may boost performance indirectly through psychological factors, requiring longer or combined training for measurable neural effects.
