title: [Comparison of aerobic performance of leg and arm muscles in cross country skiers].
abstract: Recently there was a tendency to increase usage of double poling during cross country skiing and accordingly to increase loading of the arm muscles. The aim of the study was to compare the aerobic performance of cross country skiers in the incremental double poling and running tests till exhaustion. Eight junior subnational level cross country skiers ( V(O)2max 70 (66-72) ml/min/kg) have participated in the study. The rate of blood lactate increase during double poling test was higher than during running test. Double poling V(O)2peak was 88 (84-93)% from running V(O)2max. Relative anaerobic threshold (% V(O)2max at AT), closely linked to the current aerobic performance, was substantially lower in double poling test compared with running test: 79 (57-83)% and 94 (90-98)% respectively. We suggest that the main reserve for further increase of aerobic performance of cross country skiers lies in an increase of double poling aerobic capacity.
