Key result
First-class female cross-country skiers had an 11 beats/min higher heart rate and 7.7 ml/min/kg lower oxygen consumption at the anaerobic threshold during maximal exercise than master skiers (p<0.05).
Why the study?
The study was conducted to estimate the functional features of the cardiorespiratory system during maximal bicycle ergometer testing in female cross-country skiers with different skill levels.
Does skill level affect the cardiorespiratory response during a maximal exercise cycle ergometer test in female cross-country skiers?

Does skill level affect the cardiorespiratory response during a maximal exercise cycle ergometer test in female cross-country skiers?
Mean Difference: 11
p-value: p=<0.05
Higher skill level in female cross-country skiers is associated with more efficient oxygen transport mechanisms and lower cardiovascular tension during maximal exercise.
Objective: to estimate the functional features of the cardiorespiratory system of female cross-country skiers with different skills levels at the maximal bicycle ergometer test. Material and methods: 70 female cross-country skiers were divided into three groups. The first group included 21 cross-country skiers with first adult sporting rank, the second — 25 candidates in master of sports, the third group — 24 sport masters in cross-country skiing. Maximal exercise tests were used to determine cardiorespiratory fitness via spiroergometric system «Oxycon Pro» (Jaeger, Hoechberg, Germany). Results: The most notable differences were observed between the first-class and the masters of the sports groups. In the first-class group the heart rate during the maximal exercise test was, on average, 11 beats/min higher than in the master of sports group (p<0.05), and the oxygen consumption at the anaerobic threshold was, on average, lower by 7.7 ml/min/kg (p < 0.05) when comparing the same groups. Conclusion: The influence of skills levels on physiological parameters at maximal bicycle ergometer test was shown. The capacity in the first group occurs due to cardiovascular system tension, and the same in the group high qualification skiers happen due to the mechanisms of oxygen transport development.

Garnov et al. (2023) conducted a cross-sectional in Cross-country skiers (n=70). Lower skill level (first adult sporting rank) vs. Higher skill level (master of sports) was evaluated on Heart rate during maximal exercise test (11 beats/min higher, p=<0.05). First-class female cross-country skiers had an 11 beats/min higher heart rate and 7.7 ml/min/kg lower oxygen consumption at the anaerobic threshold during maximal exercise than master skiers (p<0.05).
