Abstract

The purpose of this investigation was to determine the effects of roller ski and running exercises on

Energy Output, MET, Fat and carbohydrate metabolism of cross- country skiers. Ten subjects 4 women

(163.0 ± 6.71cm, 57.50 ± 5.97kg, 17.25 ± 2.18 age) and 6 men (171.33 ± 4.61 cm, 55.16 ±8.23kg, 16.50

±1.56 age) were tested on 2 occasions using a different mode of exercise for each test: running and

roller skiing. The test were completed with a portable breath-by-breath gas exchange measurement

system (Version Vmax ST 10). Statistical analyses were performed with SPSS (version 100) Means and

standard deviations (SD) are given as descriptive statistics. A repeated measurement ANOVA was used

for evaluation within groups and between groups’ differences by independent sample ti-test. There is a

significant difference between two exercises model Fat Metabolism parameters in 10th and 15th min.

There is no significant difference between running and roller skiing exercises at carbohydrate, energy

output and MET p>005. Within the rollerskiing and running exercises change no significantly. Result in

our study, we suggest that fat metabolism in running exercise between 10-15 minutes significantly

increase, while in two exercises modes Q, Met, and CHO metabolism increased at the same degree.
