Comportamiento fisiológico de boxeadores élite en Colombia a 2600 metros de altura
Ruiz Castillo, Mauricio | 2017-08
Summary : Boxing requires high levels of oxygen consumption (VO2 máx), which is measured by ergospirometry and can be conditioned by many factors such as weight and atmospheric pressure so that the results also be individualized, must take into account these Factors
Objective: To analyze the relationship between weight and VO2 máx of elite Colombian boxers, exposed to 2600m in height. Standardize race speed ranges as a performance measure.
Method: A cross-sectional study of elite Colombian boxers who analyzed VO2max, defined as the maximum oxygen consumption plateau at the end of an ergospirometry; After 2 weeks of training at 560 mmHg; Presenting measures of central tendency, dispersion, location. Differences tested with Kruskal Wallis test.
Participants were 17 boxers, reporting VO2 máx of 50.0 ± 10 ml / kg / min, FC Max of 176 ± 17 bpm and Vel Max of 9.5 ± 1 MPH; A ventilatory threshold at 40.9 ± 7 ml / kg / min, with a velocity of 8.0 ± 2 MPH and HR of 158 ± 15 bpm. The results of light, light, medium and heavy categories are respectively: 54.0 ± 6; 51.6 ± 17; 48.0 10; 44.9 ± 6; (P = 0.0503).
Conclusions : There is no significant difference of VO2 máx by weight categories. A finding of a lower level of VO2 max in the literature however is not comparable with each other by different altitude levels. The speed was very similar by categories and with international studies, so it could be a good marker of performance.
