The cardiovascular condition of five members of the University of B.C. cross country team was checked weekly with the Cameron Heartometer. Heartograph measures taken twenty-four hours before competition were compared to the coach's subjective appraisal of the athlete's performance to see if fluctuations in any of the measures corresponded to fluctuations in performance. A record of the runners' training load was also kept. Using case study methods the information above was observed and studied to see if the heartometer is a practical device for anticipating staleness, incipient infection or general inability to adapt to the training load. The autonomic nervous tone of the athlete is indirectly represented by the heartometer measures. The measures of the heartograph were also statistically interpreted to see which measures showed significant trends during the nine weeks of testing. Each of the five athletes showed results that were different than those of his teammates. One athlete, with a long history of endurance training, significantly improved most of the aspects of his cardiovascular condition in the short nine-week season. This runner ran well throughout the season with no apparent staleness. Another athlete, who has had severe attacks of asthma, performed well until attempting a particularly heavy amount of work. After this work he ran a very poor race. The heartograph showed a rest-to-work ratio that had dipped sharply from previous readings, on a graph taken twenty-four hours before this race. A third subject had been training all year. From the beginning of testing this runner showed strong pulse wave responses. However, his performance was not as would be expected from an athlete that was adapting well to his training. During the season the athlete had a slight nervous breakdown which indicates that he was not adapting to the stresses of his overall programme. With a reduction of training his running improved somewhat as did certain measures of his pulse wave. The fourth subject trained hard but did not perform as well as might be expected for an athlete undertaking this amount of training. The fifth man trained moderately throughout the season. This subject was basically a middle distance runner and participated in cross country in preparation for the track season. His heartograph measures showed gradual improvements and three - systolic blood pressure, pulse pressure and rest-to-work ratio - showed significant linear increase during the training period. This runner performed as expected in all races. Four measures of the pulse wave showed parallel development with improving cardiovascular condition; these were the diastolic surge, rest-to-work ratio, systolic blood pressure and pulse pressure. The rest-to-work ratio showed variations that on observation best indicated staleness or inability to adapt to the training load. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate

Background: Despite the introduction of running footwear in the 1970’s, running injury rates continue to be unacceptably high. The subsequent revival of barefoot running and the introduction of minimalist footwear occurred, in an attempt to reduce injury rates and increase performance. There is much contention in the literature around the effectiveness of these footwear conditions. Furthermore individual responses have recently been proposed to provide more accurate and reflective conclusions than the use of mean data. Objectives: Twofold: a) to compare the biomechanical, physiological and perceptual responses between the shod, minimalist and barefoot footwear conditions and b) to assess and compare individual responses under these footwear conditions. Methods: 26 well-trained, male, habitually shod endurance runners, aged between 18 - 30 years completed three experimental sessions on an indoor runway and motorized treadmill. Each session was completed in either the shod, minimalist or barefoot condition, running at 15km.h-1. Variables assessed included stride rate, stride length, impact peak, vertical impact and average loading rate and strike time (biomechanical); heart rate, oxygen consumption and electromyography (physiological); and rating of perceived exertion and body discomfort (perceptual). Results: Biomechanics – Stride rate and stride length showed a significant (p<0.001) increase and decrease respectively when running in the minimalist or barefoot conditions versus shod. Running barefoot versus the minimalist and shod conditions resulted in a significantly (p<0.001) greater vertical impact loading rate. Strike time was significantly (p=0.008) reduced running in the minimalist and barefoot conditions versus shod. Physiology – Running barefoot versus shod resulted in a significantly (p=0.02) reduced heart rate and Tibialis Anterior activity (p=0.005). There was a large variability in individual responses for many variables, with responders and non-responders seen. Conclusion: The study suggests that there are significant differences between all three forms of running for some variables. It was further noted that there is support for the proposal that individual responses are highly variable and should be analysed accordingly

Six male long-distance runners participated in this study to evaluate the responses to exercise at 90% and 100% vV02max. Subjects participated in five maximal exercise tests: one incremental, three tests at 90% vV02max, and one test at 100% vV02max. The results of this study demonstrate that V02max can be elicited in a constant-velocity test at 90% vV02max.

This study compared the center of mass behavior and muscle activation patterns during Chi running and normal running. The study included 10 participants, both male and female, who were recreational runners training at least 5 days a week. Thirty-second trials were collected continuously on a treadmill in the University of Texas Non-linear Biodynamics Laboratory. The variables being examined were the COM vertical position and COM acceleration in the A/P direction, the angle of lean, the gravitational moment about the ankle, and EMG amplitude and duration from four leg muscles. Although no significant differences were found between the two conditions for any of the dependent measures, there was a visible change in running form. A larger number of participants or a different set of dependent measures may be required to observe statistically significant differences. / text
