Effects of Running Speed, Fatigue, and Bracing on Motor Control of Chronically Unstable Ankles
… the most common injuries for participants in running and jumping sports. Following an initial sprain injury, many (30-40%) will develop chronic ankle instability (CAI), characterized by a perception of instability and repeated sprain injuries. Quasi-static test methods indicate poor postural …

Monitoring of training and racing of long distance runners using heart rate monitors
… rate can be used to measure intensity during running. Accordingly, heart rate responses were examined in long distance runners during different types of training and racing. The thesis also examined the effects of environmental and body temperature on heart rate during submaximal and maximal …

Ergonomic Responses to Aerobic Steady-State Walking and Running Performance in Children
… exertion scales in children, 2) the influence of running speed and other physiological variables such as body composition, body weight, age, and gender on the achievement of an aerobic steady-state running performance in children, and 3) the relationship between steady-state oxygen uptake and …

Examining physiological roles of adipose derived VEGF: Consequences in substrate availability and endurance exercise capacity in adipocyte specific VEGF deficient mice
… at 20 m/min, 10-degree incline. Maximal running speed, using incremental increases in speed at 30-second intervals, was tested at 25 weeks of age. Beginning at 6 weeks, and continuing with all time points, endurance run time to exhaustion was 30% lower in adipoVEGF-/- compared to controls …

Tibial Acceleration and Shock Attenuation in Female and Male Distance Runners at Different Levels of Body Weight Unloading
Running popularity has led to a rise in chronic lower limb injuries resulting from cumulative loading. Many of these injuries are tibial stress fractures. Tibial accelerometers are commonly used to measure tibial stress and may even be predictive of injury at the distal limb. Lower body positive …

The Effect of Shifts in Reward Magnitude and Changes of Schedule of Reinforcement on Resistance to Extinction
… the resistance to extinction of an alley running response as a function of various combinations of reward sizes (l or 10 pellets) and schedules of reinforcement (50 or 100%). Three experimental phases were used (acquisition, shift of reward, and extinction). Three measures were taken in …

Physiological and biochemical responses to exercise and training in adolescent runners
… first study assessed the reliability of absolute running speed, V02, and HR that correspond to the fixed blood lactate reference values of 2.0 and 2.5 mmo1. L"1 and the lactate threshold (LT) and found these measures to be reliable after endurance-trained adolescent runners completed two identical …

Prediction of high-speed shaft natural frequencies employing harmonic excitation
… purpose of determining the practicality of low-speed harmonic excitation of high-speed natural frequencies. The analytical development and analysis utilized SPAR, a finite element program, and a bearing stiffness program to determine frequencies for the first through fourth harmonics of natural …

The development of a dynamically coupled axial-torsional-lateral point transfer matrix for a whirling eccentric mass
… had harmonic forms at twice and three times running speed. Static load terms were also found as a result of the synchronous whirl analysis. These static, 2 times and 3 times terms are extended forcing functions which can be used in static, 2 times and 3 times running speed analyses, …

Detecting Transient Changes in Gait Using Fractal Scaling of Gait Variability in Conjunction with Gaussian Continuous Wavelet Transform
… of spatiotemporal variations during walking and running. This study evaluated the use of time-series analyses to determine gait parameters during running. Subjects were college-age female soccer players. Accelerometer data were collected using GPS-embedded trunk-mounted accelerometers. Customized …

Establishing the physiological, anthropometric and training characteristics, and pacing patterns of runners racing in a tropical ultra-marathon
… arm and calf girths, VO2max and peak treadmill speed (PTS) were taken during session 1 while the lactate threshold (LT) and running economy (RE) were assessed during session 2. For the second study, FIN of the 161-km (N=47) and 101-km (N=120) categories of the race were divided into thirds …

The effect of supplementary Elliptical training protocols on running performance in trained runners
… trainer and stepper in comparison to treadmill running. It was therefore suggested that the elliptical trainer and stepper could be useful substitutes for running when periods of reduced running load are required, such as during rehabilitation from an injury, or as a means to increase running …

Relaxation training, flexibility training, and their relationship to running speeds at short distances
… relaxation training and flexibility training to running speeds of high intensity at three short distances for high school males. In addition to the main problem, the following sub-problems were established: (1) Was there a significant difference of effects between the relaxation training and the …

Use of Technology for Physical Activity Assessments and Intervention Applications
… theory coefficients showed lower values for the running speed (0.70) versus the walking speeds (all > 0.84) with the majority of the variability derived from the participant (68% - 88%). Acceptable validity was found overall (Pearson's r = 0.895 - 0.902, p < 0.0001), with overall mean absolute …

Use of Cross-Correlation Analysis to Determine Heart Rate Kinetics During Non-Steady State, Fatiguing Exercise in Collegiate Female Soccer Athletes
… of HR and external work rate. Heart rate and running speed were cross-correlated yielding a cross-correlation function (CCF) and analyzed for its peak (CCFmax) and time delay (CCFlag). Modeled exercise data where the time constants for HR (τ) increased from 2-120 sec. yielded linear decreases …
