3D intra-segmental coordination in backpack load carriage with and without trekking poles

Backpack carriage is common in outdoor activities. These outdoor adventures require carrying a significant load for an extended period, demanding continuous physical effort and locomotor adaptations. The aim was to analyse and compare the intra-segmentar coordination of the shank, during gait cycle, while carrying a backpack, with and without trekking poles. The protocol involved one male recreational hiker walking 30 meters on level terrain at a self-selected pace, while carrying a backpack under two conditions: with and without trekking poles. The backpack was loaded with 20%of the participant body weight. Data were collected using Phyphox application, through two mobile phones, that were fixed above lateral malleolus of the right and left shank. For assess intra-segmental coordination it was performed phase graphs for each condition and movement plan. In the experimental condition with trekking poles, in the sagittal plane, greater fluidity and less dispersion were observed during the swing phase.
