Energy and macronutrient intakes during a 4‐day, 51‐km cross‐country ski march
| CNTRL(n = 5) | CHO(n = 9) | PRO(n = 10) | P‐value | |
|---|---|---|---|---|
| Energy intake, MJ/day | 11.5 (1.7) [9.5, 13.0] | 13.4 (2.7) [7.8, 16.3] | 12.4 (2.5) [8.6, 16.8] | 0.38 |
| Protein intake, g/day | 109 (14) [92, 124] | 100 (21) [66, 123] | 155 (26)a[108, 191] | <0.001 |
| Carbohydrate intake, g/day | 340 (51) [281, 285] | 443 (82)b [252, 513] | 335 (82) [189, 490] | 0.01 |
| Fat intake, g/day | 102 (17) [83, 117] | 111 (27) [62, 146] | 109 (22) [70, 141] | 0.76 |
Values are mean (SD) and range [min, max]. One individual excluded from PRO due to incomplete food logs. CNTRL, control group; CHO, carbohydrate supplement group; PRO, protein supplement group. Values compared by one‐way ANOVA with Tukey's correction.
a
Significantly different from CNTRL and CHO, P < 0.01.
b
Significantly different from PRO, P = 0.02.
