The impact of perceived comfort of weighted shoes on kinematic and kinetic parameters in the running gait
The aim of this study has been to measure the impact of shoe weight on perceptions and their relationship with running gait parameters. The fluctuation of the kinetic (e.g. pressure distribution), kinematic (e.g. knee angle) and subjective parameters (e.g. perceived weight) have been analysed by cha...

| Sumario: | The aim of this study has been to measure the impact of shoe weight on perceptions and their relationship with running gait parameters. The fluctuation of the kinetic (e.g. pressure distribution), kinematic (e.g. knee angle) and subjective parameters (e.g. perceived weight) have been analysed by changing the shoe weight. More in detail, it has been tested whether there is a significant difference between the graduate increase and graduate decrease of the shoe’s weight perception and movement pattern in the gait cycle. Eighteen healthy participants (age: 25±2 years; height: 179±7 cm; body mass: 74±6 kg) without lower extremity injuries have taken part of the experiment. All the subjects were not professional runners but they practice sports at least 3 hours per week. Subjects have run on a treadmill at 10 km/h for 16 times during 2 minutes. In the first eight the shoe weight was increased from a neutral condition (N: 350 grams) to a weighed one (A: +50 grams; B: +150 grams; C: +315 grams) or to the neutral again (N) in a randomized order. The second phase has been performed in the opposite direction, from a weighed shoe to a neutral one (AÆN; BÆN; CÆN; NÆN). Whereas the kinetic parameters have been recorded with Moticon system, motion capture Vicon has been used to collect the kinematic evolution. Kinetic results have shown differences between the neutral condition and the weighted ones: increase of the cycle time, swinging phase and the reduction of the contact time for the heavier shoes. In addition, the maximal knee angle during swinging phase tends to be larger when the shoe weight increases. It has been interpreted as an unconscious reaction of the body to make the steps more stable. Subjective results revealed no statistical differences when the shoe order is changed. This study confirms that people detect heavier shoes easily from 150 grams onwards. Perceived weight results converge in the 315 grams for the first and second phase. Objective and some subjective parameters (knee angle, COP distance and velocity) have shown this pattern and it has been declared that perceptions have an effect in kinematic and kinetic parameters. |
