Comparison of average distance travelled and speed while wearing different types of face mask compared with no mask
| Comparison | Average distance travelled (kilometres) with mask | Average distance travelled (kilometres), no mask | Estimated average difference in distance (km, 95% CI) | Average speed (km/hour) with mask | Average speed (km/hour), no mask | Estimated average difference in speed (km/hour, 95% CI) |
| Distance travelled (km) during exercise (N=71) | ||||||
| Cloth mask—no face mask | 2.75 | 2.82 | −0.07 (−0.15 to 0.01) | 11.06 | 11.37 | −0.31 (−0.64 to 0.02) |
