Table 3. Regression coefficients of weather and physical activity.
| Total n = 1219, 110888 hours | Weather and PA across season | Season difference | ||
|---|---|---|---|---|
| PA and weather | Colder months d (n = 631, 57055 hours) | Warmer months d (n = 588, 53833 hours) | Colder months vs. Warmer months | |
| PA | 524.7 (4.1) | 597.4 (5.2) | 329.2 (14.0) | |
| Precipitation a | -10.2 (9.2) | 38.2 (12.7)** | -20.6 (12.6) | P < 0.01 |
| Temperature a | 20.2 (0.9)** | 10.6 (0.9)** | 33.3 (2.1)** | P < 0.01 |
| Wind a | 3.7 (1.5)** | -8.4 (5.2)** | 15.0 (2.2)** | P < 0.01 |
| R2 within b | 1.2% | 0.4% | 2.8% | |
| Rho c | 10.3% | 8.3% | 10.4% | |
| F | 3.1** | 3.6** | 3.6** | |
a Precipitation; measured as mm, Temperature; measured as °C, Wind; measured as m·s−1.
b R2 within; How much precipitation, temperature and wind explains of the variance in Overall PA
c Rho; How much of the variance is due to difference across time (interclass correlation).
d Colder months: November-March, Warmer months: April-October
**Statistical significant (P < 0.01)
*Statistical significant (P < 0.05), ns Non-significant.
PA: Physical activity measured as triaxial counts·min-1 (mean per hour).
