González-Parra G, Mora R, Hoeger, B. Maximal oxygen consumption in national elite triathletes that train in high altitude. J. Hum. Sport Exerc. Vol.8, No. 2, pp. 342-349, 2013. Triathlon is considered an endurance sport composed by the individual disciplines of swimming, cycling and running which are generally completed in this sequential order. It has been suggested that triathlon performance can be predicted by maximal oxygen uptake (VO2max). However, it has also been suggested that some variables such age, gender, fitness, training and ventilator muscles may affect VO2max. It is the aim of this research to measure and analyze the VO2max of 6 national elite triathletes and one national juvenile triathlete, with long experience, training in a high altitude city (1650m). We compare VO2max for female and male groups. We found differences at the VO2max values for these groups. Additionally, we also found high values of VO2max for these young elite triathletes despite their relative short age, but long sport age.

Villaroel C, Mora R, González-Parra GC. Elite triathlete performance related to age. J. Hum. Sport Exerc. Vol. 6, No. 2, pp. 363-373, 2011. Triathlon is considered an endurance sport composed by the individual disciplines of swimming, cycling and running. The level of elite triathlon improves every year and the studies of several factors that help to improve the performance of triathletes who compete at Olympic, World Series, European, Pan-American, Commonwealth and others important events are increasing. It has been suggested that triathlon performance decline with age. However, it has also been suggested that experience is an important variable related to performance in sports and especially in crucial events. It is the aim of this research to measure and analyze the correlation between performance and age in international male elite triathletes that have participated in World Cups, Championships Series and World Championships Series from years 2007, 2008, 2009 and 2010. We found that in several cases there is a positive correlation between age and performance. Additionally, we found that the mean age of the top ten finishers in Olympic Games triathlon was higher than in the other triathlons. All these results suggest that experience is important in most relevant international elite triathlon events.
