High Resolution MEMS Accelerometers to Estimate VO2 and Compare Running Mechanics between Highly Trained Inter-Collegiate and Untrained Runners
BACKGROUND The purposes of this study were to determine the validity and reliability of high resolution accelerometers (HRA) relative to VO(2) and speed, and compare putative differences in HRA signal between trained (T) and untrained (UT) runners during treadmill locomotion. METHODOLOGY Runners performed 2 incremental VO(2max) trials while wearing HRA. RMS of high frequency signal from three...
متن کاملOxygen cost and energy expenditure of running in trained runners.
The oxygen cost and energy expenditure of submaximal treadmill running was evaluated in 9 male distance runners. The oxygen consumption--running speed relationship was highly significant (r = .917) and linear over the entire aerobic range. The caloric cost of 0.97 Kcal/kg/k was in close agreement with values found in the literature and was independent of running speed. The caloric cost per unit...
متن کاملRelationship between 800-m running performance and running economy during high-intensity running in well-trained middle-distance runners
Running economy (RE) at an intensity above the lactate threshold (LT) is reported to be the most important aerobic capacity for estimating 1,500-m running performance. The reason that the RE at intensity better reflects the energy metabolism during a 1,500-m run, is that it is performed above the LT intensity running. This study clarified the relationship between an 800-m run, which is performe...
متن کاملRelationship between muscle strength, power and stiffness and running economy in trained male runners.
PURPOSE In this study, a comparison was made between muscle strength, power and muscle and tendon (km and kt respectively) stiffness of the triceps surae muscle group and running economy (RE) in trained male runners. METHODS Twelve well-trained male runners (age = 21 +/- 2.7 y, height = 178.1 +/- 7.1 cm, body mass = 66.7 +/- 3.2 kg, VO2max = 68.3 +/- 4.3 mL x kg(-1) x min(-1), 5000-m time = 1...
متن کاملRear-foot kinematics in runners with PFPS during walking, squatting and uphill running
Background Patellofemoral pain syndrome (PFPS) is the most common overuse injury in distance runners. A pilot investigation found that runners with a history of PFPS exhibited increased rear-foot eversion and reduced rear-foot dorsiflexion compared to uninjured controls during level treadmill running [1]. The aim of the present study was to investigate whether these kinematic alterations were a...
