| ABSTRACT |
| The
purpose of the study was to investigate the effects of extreme environments
on mood state changes in hypoxic conditions and cold conditions in
comparison to baseline conditions. The research design involved participants
completing a two-hour stationary cycle ergometer ride at a simulated
altitude of 2,500 metres, O°C, and normal laboratory conditions at
a pace equivalent of lactate threshold. Eight male elite cyclists
(Age: M = 26.23 yrs., SD = 6.74) completed the hypoxia- normal cycling
trials. Ten male highly trained cyclists (Age: M = 23.34 yrs., SD
= 5.45) participated in the cold-normal trials. Mood was assessed
before, after one hour, and after two hours using the 24-item Brunel
Mood Scale. MANOVA results indicated no significant interaction effect
for mood changes over time by environment condition (Wilks' Lambda
= .73, p = .32, Eta2 = .05), a significant main effect for mood changes
over time (Wilks' Lambda = .61. p < .001, Partial Eta2 = .15) and
a significant main effect for differences in mood by condition (Wilks'
Lambda = .72, p < .000, Partial Eta2 = .15). Results indicated
that increased anger, depression and fatigue were associated with
performing at altitude, particularly after two hours of exercise.
Collectively, results lend support to the notion that altitude is
associated with negative mood states, although it should be noted
that environment conditions did not affect the change in mood states
over time. We suggest that further research is needed to explore mechanisms
that individuals use to regulate negative mood during strenuous exercise.
