THE EFFECT OF STEP RATE TRAINING ON RUNNING ECONOMY AND BIOMECHANICS
… a determinant of running performance. Increased step rate has been correlated with improved running economy, but it is unknown whether these improvements can be maintained with chronic training. The purpose of this study was to determine if a step rate training intervention improves running …

Effects of Dynamic, Static Stretch, and Proprioceptive Neuromuscular Facilitation on Running Velocity, Step Length, and Step Rate
… on collegiate female sprinters on the velocity, step length and step rate. Ten NCAA Division I female sprinters ranging in age from 18 to 22 participated in the study. A forty five meter sprint was performed with the section from thirty to forty meters digitally recorded and later analyzed for …

The Association Between Step Intensity and Cardiorespiratory Fitness in Adults
… of CRF, and findings suggest that daily steps are positively associated with CRF. Whether step intensity is associated with CRF has not been rigorously investigated. Purpose: To examine the association between step intensity and CRF. Methods: Participants include 423 physically inactive …

The association between running kinematics and common overuse injuries in runners : implications for injury and rehabilitation
… whether gait retraining, in the form of a step rate intervention, improves running kinematics and clinical outcomes amongst a group of 12 injured runners with patellofemoral pain. Findings: The repeatability study demonstrated good to excellent repeatability with low measurement errors for …

Striding towards fewer falls: quantifying gait from flat and stair terrains to predict falls in older adults
… fall risk assessments used in fall prevention strategies suffer from a range of limitations. The use of wearable inertial sensors (IMUs) to quantitatively assess gait and predict falls can help fill these gaps. The aims of this research were focused on exploring the utility of sensor-based gait …

The role of well testing in geothermal resource assessment
… of the selected methods. Analyses of data from step-rate injection tests, temperature and pressure profiles as well as discharge tests conducted in the Reykjanes geothermal field are presented. Six wells, RN-12, RN-13b, RN-17b, RN-18, RN-23 and RN-29 were selected for the study. The computer …

System specific power reduction techniques for wearable navigation technology
… a wearable navigation prototype in a fully integrated hardware form factor, but one of biggest barriers to usability of the device is its excessive power consumption. As such, the goal of this work is, broadly, to- (1) Understand the largest sources of power consumption in the initial navigation …

Effects of Increases in Mental Workload on Avoidance of Ground Hazards
… three levels of mental workload (No Load, Moderate load, and High load), all as within-subject effects. Mental workload was increased from the "No Load" to a "Moderate" level by requiring the participants to perform a mental arithmetic task while walking. Mental workload was increased from the …

Monitoring and control of the cardiovascular system during indoor exercise
… gradient to stimulate the exerciser's heart rate following a predefined profile. In this thesis, an automated treadmill system has been developed, which includes wireless portable ECG and tri-axial accelerometer sensors, and a Labview based control module. Based on this automated system, …

Enhancement of the Brick constitutive model to incorporate viscous soil behaviour
… viscous behaviour, including creep and strain rate dependent stiffness, which can be very significant for clay soils. The principal aim of the work was to incorporate such behaviour into the Brick model. Two main approaches were identified manipulating either the velocity of the bricks or the …

Selective catalytic reduction: testing, numeric modeling, and control strategies
… through the entire catalyst length. Ammonia feed rate control testing was done on the experimental setup to improve ammonia and NOx emissions from the catalyst. Three control algorithms were used: feed forward control, using a pre ammonia injection ceramic NOx sensor; a feed forward plus feedback …

THE INFLUENCE OF THE BACK FUNCTIONAL LINE ON LOWER EXTREMITY FRONTAL PLANE KINEMATICS AND KINEMATIC PREDICTORS OF LOADING DURING RUNNING
… of gait. GM and VL muscle mean amplitude demonstrated a varied response. During the PA phase, both the GM and VL muscles increased during the unilateral condition and decreased during the bilateral condition. During LR phase, GM and VL muscles increased during both arm swing constraint …
