Incline dependence of the power-duration relationship in cross-country skiing.

ABSTRACT:

Introduction

This study aimed to develop a methodology for establishing the power-duration relationship in cross-country skiers and to investigate the influence of incline on critical power ( CP ) model parameters.

Methods

Twelve trained male cross-country skiers performed four constant work-rate predictive trials on a motor-driven treadmill, using the double poling sub-technique, to determine their power-duration relationships at 2° and 8° inclines in a randomized order. The testing protocol also included maximum speed tests performed at both inclines. Power-duration relationships were modeled using a modified expression of the three-parameter critical power model.

Results

The derived power-duration relationships were significantly different between the two inclines.
