Differences in Ground Contact Time Explain the Less Efficient Running Economy in North African Runners
The purpose of this study was to investigate the relationship between biomechanical variables and running economy in North African and European runners. Eight North African and 13 European male runners of the same athletic level ran 4-minute stages on a treadmill at varying set velocities. During the test, biomechanical variables such as ground contact time, swing time, stride length, stride fr...
متن کاملRunning Speed Can Be Predicted from Foot Contact Time during Outdoor over Ground Running
The number of validation studies of commercially available foot pods that provide estimates of running speed is limited and these studies have been conducted under laboratory conditions. Moreover, internal data handling and algorithms used to derive speed from these pods are proprietary and thereby unclear. The present study investigates the use of foot contact time (CT) for running speed estim...
متن کاملAccuracy of PARTwear inertial sensor and Optojump optical measurement system for measuring ground contact time during running Brief running head: Ground contact time accuracy in portable measurement systems Authors:
The aim of this study was to validate the detection of ground contact time (GCT) during running in two differently working systems: a small inertial measurement sensor, PARTwear (PW), worn on the shoe laces, and the optical measurement system, Optojump (OJ), placed on the track. Twelve well-trained subjects performed 12 runs each on an indoor track at speeds ranging from 3.0 9.0 m·s-1. GCT of o...
متن کاملRunning for Exercise Mitigates Age-Related Deterioration of Walking Economy
INTRODUCTION Impaired walking performance is a key predictor of morbidity among older adults. A distinctive characteristic of impaired walking performance among older adults is a greater metabolic cost (worse economy) compared to young adults. However, older adults who consistently run have been shown to retain a similar running economy as young runners. Unfortunately, those running studies did...
متن کاملExplosive-strength training improves 5-km running time by improving running economy and muscle power.
To investigate the effects of simultaneous explosive-strength and endurance training on physical performance characteristics, 10 experimental (E) and 8 control (C) endurance athletes trained for 9 wk. The total training volume was kept the same in both groups, but 32% of training in E and 3% in C was replaced by explosive-type strength training. A 5-km time trial (5K), running economy (RE), max...
