![]() This is critical for reliably providing VO 2max predictions, to reduce the chance of error in training prescriptions from overestimations or underestimations of VO 2max. Thus, further investigation of the accuracy of several VO 2max prediction equations is warranted in various athletic settings, such as women field hockey athletes, to provide practitioners with appropriate equations for their population. Further, despite previously reported similarities in aerobic capacity between elite men and women field hockey athletes and endurance athletes, prediction of VO 2max can be dependent upon sex. However, there are differences in the aerobic capacity of athletes depending upon the sport in question, which may affect the validity of VO 2max equations from the Beep test in certain populations. Equations have been validated within the general population, recreationally active men and women, children ages 8–19 years, and men squash and distance athletes. In order to estimate VO 2max from Beep test performance, several equations have been developed that use the speed of the final stage achieved during the Beep test. Although VO 2max of men and women within the general population has proven to be correlated with the final shuttle speed during the Beep test, the ability of 20-m shuttle run tests to accurately predict VO 2max outcomes in collegiate athletes remains limited. A common and reliable test used to predict aerobic capacity is the progressive, multistage 20-m shuttle-run test or “Beep” test, in which the athlete runs 20-m laps at increasingly faster speeds until volitional fatigue. Therefore, alternative, field based, methods for predicting VO 2max have been developed. Nonetheless, the aforementioned assessment of aerobic capacity requires expensive laboratory housed equipment and highly trained personnel, which are not always accessible or feasible for testing multiple athletes in team settings. VO 2peak is more indicative of exercise tolerance than the maximal ability to transport and utilize oxygen, since individuals may select to discontinue exercise prior to achieving VO 2max. However, VO 2peak, the highest value obtained during exercise, should not be used interchangeably with VO 2max. The maximal oxygen consumption (VO 2max) refers to the highest physiological value attainable, as indicated by a plateau in maximal oxygen consumption during exercise. Due to the evidence that field hockey is predominately an aerobic sport, testing for aerobic capacity is imperative in understanding the athletes’ preparedness for competition and for modification of training programs.Īerobic capacity can be validly and reliably assessed through measurement of inspired and expired gas exchange during a maximal graded exercise test. Further, according to time motion analysis, 95% of men’s field hockey competitions consist of low intensity tasks (e.g., walking, jogging, standing), while 5% of the competition is comprised of high intensity tasks (e.g., sprinting). The aerobic energy system is predominant during collegiate women’s field hockey, as games consist of two 35-min halves with high-intensity movements comprising approximately 20% of that duration. For accurate estimates of VO 2max, the clientele’s age, fitness level, and training history should be considered when selecting equations.įield hockey is a field-based, intermittent, team sport comprised of short bouts of high intensity sprints and longer bouts of walking and jogging. ![]() The Ramsbottom and Flouris estimates of VO 2max from 20-m shuttle performances may be used in this population. Clair-Gibson equations overestimated VO 2max, and are not recommended for use with women collegiate field hockey athletes. The Chatterjee, Leger, Leger and Gadoury, and St.
