Abstract/OtherAbstract:
We studied relationships between age and aerobic capacity in three groups of subjects adhering to different exercise modalities. A total of 203 men aged 20-90 years were examined: 52 speed-power track and field athletes (SP), 89 endurance runners (ER) and 62 untrained individuals (UT). Maximal exercise characteristics were obtained during a graded treadmill test until exhaustion: oxygen uptake ( V ˙ O 2 m ⁢ a x ), heart rate (HR(max) ), oxygen pulse (O(2) Pulse(max) ) and maximal distance (Dist(max) ). Information about training history and weekly training amount was collected. A linear model of regression was adopted. V ˙ O 2 m ⁢ a x in SP was lower than in ER, but significantly higher than in UT. The cross-sectional rates of decline in body mass-adjusted V ˙ O 2 m ⁢ a x and Dist(max) were significantly smaller in SP than in ER and UT. About 80 years of age, the levels of V ˙ O 2 m ⁢ a x and Dist(max) reached similar values in SP and ER. The decline in HR(max) , but not in O(2) Pulse(max) was suggested as a cardiac adaptation accounting for between-group differences in V ˙ O 2 m ⁢ a x loss. Weekly training volume was a significant positive predictor of age-related changes in aerobic capacity. In conclusion, not only endurance, but also speed-power exercise appears adequate to ensure an elevated aerobic capacity at old age.
