Resume influence of the medium height altitude climate on the motion behaviour of the students in the alpine ski competition

The alpine ski course is part of our faculty’s syllabus and it takes place for two weeks in the mountain resort Vatra Dornei situated at an altitude of 802 m, having an intermontane climate. Noticing the variations of the motion behaviour of the students in this period of time, we have thought of studying to see if the change in altitude, from 165 m (Bacău) to 802 m, is somehow responsible for this different motion behaviour.

Introduction

The alpine ski course is part of our faculty’s syllabus and it takes place for two weeks in the mountain resort Vatra Dornei situated at an altitude of 802 m, having an intermontane climate. Noticing the variations of the motion behaviour of the students in this period of time, we have thought of studying to see if the change in altitude, from 165 m (Bacău) to 802 m, is somehow responsible for this different motion behaviour. Method: Our analysis aimed at comparing the values of the main physiological parameters (heartbeat frequency, respiratory frequency and arterial pressure) measured in Bacău in the case of 12 students, on a period of time of two weeks, and the values of the same parameters measured in Vatra Dornei during the next two weeks.

Discussion

Observing the functional and the motion behaviour modifications at a high altitude, we notice that these modifications are within the parameters of the general adaptation syndrome. The order in which these adaptation effects appear is the following: 1. The immediate imbalance stage, the alarm stage which appears after 24-48 hours since the arrival to the high altitude area. 2. The neural-vegetative reaction stage which, by stimulating the metabolism, produces a series of very important functional modifications.

Conclusion

Considering these facts, we think that the period of time allotted to the alpine skiing course within our faculty is long enough for some parameters, but insufficient for others, fact which brings an objective foundation for some modifications of the motion behaviour during this period of time. Another conclusion which can be drawn is that, in order to benefit from the effects of the medium height altitude climate, three weeks are necessary to re-establish the neural-vegetative functions specific to this type of climate.
