| Outline of Final Research Achievements |
This study was investigated to explore effect of hypoxia and environmental temperature on energy cost of walking. Further, we also investigated effect of these environmental factors on economical speed that can minimize energy cost of walking. As a result, economical speed was significantly slowed in hypoxia (fraction of inspired oxygen; FiO2 ~ 13%). Thereafter, we set ambient temperature as 13°C and 23°C, and FiO2 was set as 13% and 21%, respectively. Combined effects of cool and hypoxic environment on energy cost of walking and economical speed were also investigated. We found that overall energy cost unchanged irrespective of cool and hypoxia, while hypoxic condition significantly slowed ES. Conversely, there were no effects of ambient temperature which was used in the present study.
