The functional features of middle distance and long distance runners aerobic capacity and respiratory system

Object of research. Middle distance and long distance runners aerobic capacity and the connection of respiratory system indicators. We researched 19 superior level middle distance (main competition distance from 600m to 2 km, n = 9) and long distance (3 km or more, n = 10) runners. Researched sportsman have undergone respiratory system functional condition test in tranquility state and aerobic capacity test during consecutively heavier physical load. Goal of research. To determine the functional features of middle distance and long distance runners aerobic capacity and respiratory system. Tasks: 1. To compare aerobic capacity between middle distance and long distance runners. 2. To compare respiratory system functional indicators between middle distance and long distance runners. 3. Analyze and connection between runners aerobic capacity and respiratory system indicators. Hypothesis. Because of different training intensiveness and competition loads, functional capacities of respiration system are greater of the middle distance runners, and aerobic capacity indicators are greater of the long distance runners. Conclusion. 1. Absolute maximum oxygen consumption is almost the same of both middle distance and long distance runners, while relative indicators are significantly greater in the long distance runners group 2. Long distance runners first ventilator threshold and its corresponding heart contraction rate is greater in the long distance runners group, while maximum heart contraction rate is very similar in both groups during consecutively heavier physical load. 3. Running economy while moving in sub maximal speeds is very similar in middle and long distance runners groups, while during consecutively heavier physical load running economy results are better of long distance runners. 4. Most respiration function indicators are greater of middle distance runners, but statistically significant – only that of quickest expiration. 5. There is no significant correlation between the researched runners respiration function and aerobic capacity indexe
