Influence of surface condition and prolonged running on impact accelerations.

Running can be performed on different types of surfaces with distinct characteristics. These differences between the running surfaces may affect impact accelerations during prolonged running. The aim of this study was to compare the effect of the type of running surface (motorised treadmill (MT), curved non-motorised treadmill (cNMT), and overground (OVG)) and prolonged running in impact accelerations, spatiotemporal parameters and perceptual variables.

Impact accelerations during a prolonged run using a microwavable self-customised foot orthosis.

The use of custom-made foot orthoses has been associated with numerous benefits, such as decreased impact accelerations. However, it is not known whether this effect could be due to better customisation. The present study analysed the effects of the first generation of  a microwavable prefabricated self-customised foot orthosis vs.

Evaluation of impact-shock on gait after the implementation of two different training programs in older adults.

Background: Gait is negatively affected with increasing age. It is widely accepted that training produces physical-functional improvements in older adults, which can be assessed with numerous physical-functional tests. However, very few studies have been carried out using accelerometry to analyse the training effect on kinetic and kinematic variables in older adults, and there is no one that investigate the effects of two different training programs.

Influence of custom-made and prefabricated insoles before and after an intense run.

Each time the foot contacts the ground during running there is a rapid deceleration that results in a shock wave that is transmitted from the foot to the head. The fatigue of the musculoskeletal system during running may decrease the ability of the body to absorb those shock waves and increase the risk of injury. Insoles are commonly prescribed to prevent injuries, and both custom-made and prefabricated insoles have been observed to reduce shock accelerations during running.

The location of the tibial accelerometer does influence impact acceleration parameters during running.

Tibial accelerations have been associated with a number of running injuries. However, studies attaching the tibial accelerometer on the proximal section are as numerous as those attaching the accelerometer on the distal section. This study aimed to investigate whether accelerometer location influences acceleration parameters commonly reported in running literature.
