 | Exercise settings (esp. outdoors) | Studies on hypohydration | Comments |
---|---|---|---|
Hypohydrated at start | Seldom | Some | Larger effects; see text and Figure 3 |
Hypohydration extent | Mostly <2% BM | Usually ≥2% BM | Larger effects; see text and Figure 3 |
Airflow | Usually high (e.g. >2 m/s) | Usually slow (e.g. <2 m/s) and partial coverage | Exponential relation to heat transfer; decreased T sk and Q̇ sk req |
Thirst | Usually self controlled | Usually not self controlled, nor reported in results | May interact with other factors in Table |
Familiarised to, or blinded against, the psychological effect of intervention | Not applicable | Very rare | Placebo and familiarisation effects (see Figure 2 and [85]) |
