چکیده
Abstract In Paralympic cross-country sit skiing, athlete classification is performed by an expert panel, so it may be affected subjectivity. An evidence-based required, in which objective measures of impairment must identified. The purposes this study were: (i) to evaluate the reliability 5 trunk strength and 18 control developed for classification; (ii) rank measures, according largest effects on performance. Using a new testing device, 14 elite sit-skiers two upright seated press tests one simulated poling test strength. They were also subjected unpredictable balance perturbations measure control. Tests repeated separate days test–retest was evaluated. A cluster analysis run correlation evaluated, including all identify that contributed most clustering participants. Intraclass correlations coefficients (ICC) 0.71 < ICC 0.98 0.83 0.99 perturbations, respectively. Cluster identified three clusters with relevance measures. For strength, peak anterior pushing force without backrest (effect size = 0.77) ratio 0.72) significant. range motion forward 0.81) backward 0.75) contributed. High (− 0.76 r − 0.53) found between protocol, show promising results assessing empower classification.

Kinematics of sprint cross-country skiing
The purpose of our study was to characterise the diagonal stride locomotion during a new short sprint race in cross-country skiing. Thirty male cross-country skiers were sagittaly filmed on an uphill portion of the 1.2-km classic race of the world cup (2004) using a digital camera. The main body joints, skis and poles were digitised frame by frame. Results indicated higher SV and SR for similar...

Cross-country ski racing has evolved rapidly in recent years. Of particular interest has been the development and proliferation of the faster freestyle or skating techniques. In spite of changes in technique and equipment, the fact that elite cross-country ski racers have some of the highest aerobic power values reported for endurance athletes has not changed. Successful ski racers have higher ...
