ABSTRACT
Purpose:
Peak aerobic capacity (VÌO2peak) declines with age, but running economy (RE) may not. We evaluated VO2peak and RE in master runners and determined whether age is associated with these measures.Methods:
In a cross-sectional study, runners completed two running tests within four weeks of a goal race of 10-26.2 miles. Subjects ran for five min at 88% of predicted maximum heart rate, approximating a marathon-intensity effort (MIE), then performed a VÌO2peak test. Running economy in the MIE was measured using oxygen cost with body mass scaled allometrically (alloVÌO2); energy cost (EC), determined using caloric equivalents; and percent of VÌO2peak (%VÌO2peak). Pearson's correlations were used to determine relationships between age and running performance variables.Results:
Runners (n = 31, 13 females; mean age 54.9 ± 8.4 years) had a mean VO2peak of 52.5 ± 7.9 ml O2 kg-1 min-1. Age was significantly correlated with VÌO2peak (r = - 0.580, p = 0.001) and alloVÌO2 (r = - 0.454, p = 0.034). Age was related to EC in females (r = 0.649, p = 0.042) and MIE VÌO2 in males (r = - 0.600, p = 0.039).Conclusions:
In this population, age was negatively associated with VÌO2peak and alloVÌO2. Females showed a positive relationship between age and EC, while males had a negative correlation between age and MIE VÌO2. Aerobic capacity declines with age, but there may be sex differences in age-related alterations to submaximal running.
