Laterality of lower limbs during V2 Alternate in Nordic combined athletes
Journal Title: Human Movement - Year 2013, Vol 14, Issue 3
Abstract
Purpose. The aim of this study was to analyse the foot pressure distribution by cross-country skiers during the push-off phase when using the V2 Alternate skating technique depending on lower limb preference. The study also focused on whether push off during V2 Alternate would be performed more quickly and in a shorter time interval by the dominant leg than the non-dominant leg. Methods. Data were collected using a pedographic system together with synchronised video recording. Conventional dialogistic methods used in kinanthropology were used to detect the lower-limb lateral preference. Results. Statistically significant differences in the vertical component of force produced by the right/leg lower limbs was observed. However, no statistically significant differences were present in the duration when weight was transferred to one of the lower limbs. Conclusions. Although V2 Alternate is a movement task that is considered to be symmetrical (where left and right leg push-off should be practically identical), the results of the study proved otherwise. In practice, this implies that the explosive force capabilities of cross-country skiers should be trained especially for the non-dominant leg so as to ensure that a fully adequate push-off can be conducted during two-sided skating.
