Physiological Predictors of Performance in Mountaineering Ski
Keywords:maximal oxygen uptake, anaerobic threshold, body mass index, maximum isokinetic strength of knee extensors and flexors
Mountaineering ski contains elements from the alpine ski and cross-country ski. The aim of the present research was to determine the factors which contribute to performance at the phase of the uphill skiing in mountaineering ski. Ten mountaineering ski athletes took part in the present research. Pearson correlation coefficient investigated for correlation between race performance and maximal oxygen uptake (VO2max), velocity at maximal oxygen uptake (vVO2max), anaerobic threshold (AT), velocity at anaerobic threshold (vAT), body mass index (BMI), accumulation of lactic acid (La) during the race and isokinetic strength of knee flexors and extensors. The results showed a strong correlation between the race performance (time performance) and vVO2max (r=-.91), ΒΜΙ (r=.85) and vAT (r=.84), and a correlation of smaller strength between the race performance and accumulation of lactic acid (r=-.72) during the race and maximum isokinetic strength of knee flexors (r=.71). Ιn conclusion, race performance in mountaineering ski is correlated with high aerobic power, low BMI and tolerance in high lactic acid concentration.
