Subclaims¶

q2 i? Of four studies of selective attention, two found improvements, one no effect, and one a negative outcome, yielding unclear evidence strength (50%). → Deng Qianting; Wu Chongyun; Yang Luodan 2026 q2 i? Moderate-intensity concurrent cycling lowered visual attention relative to low-intensity and sedentary conditions, attributed to attentional demands of motor control. → Deng Qianting; Wu Chongyun; Yang Luodan 2026 (2)

q2 · i? · review · r3

Review synthesis of four selective-attention studies with mixed directions of effect ('unclear evidence strength (50%)'); the review codes this outcome as inconclusive.

"Four studies investigated selective attention, with two reporting significant improvements [14, 26], one showing no effect [29], and one reporting a negative outcome [32], yielding unclear evidence strength (50%)."

q2 · i? · review · r3

Review attributes this negative result to the Dupont et al. study of cycling desks used concurrently with an academic task, interpreting it as reduced cognitive resources for academic tasks.

"students engaging in moderate-intensity cycling exhibited significantly lower visual attention than those in the low-intensity group and even lower than the sedentary group, potentially attributable to the greater attentional demands of motor control during moderate-intensity cycling"
