Long term effects of doping in sporting records: 1886-2012

Best life times of top athletes, Olympic records, world records, and any doping information were collected from the IOC, IAAF, WADA and national anti-doping associations. About 1560 records of male and female athletes in 22 disciplines of summer and 4 winter sports were collected. Data were analysed for long-term effects of doping using non-linear regression techniques. Comparisons were made of pre-1932 records (when steroids became available) and post. Analyses were repeated using 1967, when widespread use of doping was formally acknowledged. After these dates records in a number of disciplines did not improve as predicted by extrapolation of pre-doping years results. Averaged best life records for ‘doped’ top athletes did not differ significantly from those considered ‘non-doped’. Even assuming that not all cases of doping were discovered, the practice did not alter sporting records as commonly believed, Doping may be damaging image of sports without benefitting results

THE MEDIOLATERAL CENTER OF PRESSURE MOVEMENT DIFFERS BETWEEN TRAINING AND RACING SHOES: A CASE STUDY

Athletes that compete on an elite level often employ running shoes specifically for racing that contain carbon plating. The purpose of this case study was to compare one female athlete’s mediolateral COP while she ran in racing and training shoes. SPM analyses revealed several regions where significant differences existed (

EFFECTS OF AN EXTENSIVE RUNNING BOUT IN NOVICE FEMALE RUNNERS

The purpose of this study was to characterize the spatiotemporal, force, and subjective effects that occur during an extensive run in novice female runners. Foot sole pressure, rate of fatigue, and speed were recorded during a 45-min flat ecological run. No significant effects were found in spatiotemporal, force-time, or rate of fatigue responses outside of the initiation phase of the running bout. When participants were grouped according to their pacing strategy, those with a decreasing speed over time exhibited significant decreases in rate of force development as time progressed. Participants tended to decrease mechanical loading variables, and increase their rate of fatigue throughout the run. Future studies should investigate a larger number of subjects to determine if these tendencies are characteristic of novice female runners
