A Study on the Cardiovascular function by athletic Events of the maximal exercise loading

&nbsp;&nbsp;We investigated the difference of the cardiovascular function in order to hold the characteristics of athletic events to advance the contest capability.<BR>&nbsp;&nbsp;We acquired scientific data from cycle Ergometer with gradual incremental work load.<BR>&nbsp;&nbsp;By this research, we drawn a conclusion as follows.<BR>&nbsp;&nbsp;1. The maximal tidal volume was revealed as G2(3270.85±985.56㎖/min), followed by G1(3040.11±531.06㎖/min), followed by G4(2970.20±300.12㎖/min), followed by G5(2682.91±379.28㎖/min), followed by G3(2395.91±572.21 ㎖/min) and there is a remarkable difference between groups(P＜0.01).<BR>&nbsp;&nbsp;2. The maximal ventilation(？&lt;SUB&gt;E&lt;/SUB&gt; max) was recorded as G2(168.58±51.88l/min), followed by G4(156.29±17.99l/min), followed by G1(141.46±22.10l/min), followed by G5(134.29±16.45l/min), followed by G3(105.23±11.09/min) and also remarkable difference was found among groups(P＜0.001).<BR>&nbsp;&nbsp;3. We could not found reliable difference the maximal respiration rate(RR) was located from G2(63.78±12.65n/min) to G3(57.55±7.92n/min).<BR>&nbsp;&nbsp;4. The maximal heart rate was appeared as G1(191.56±6.28beat/min), followed by G5(185.76±9.07beat/min), followed by G2(181.15±7.19beat/min), followed by G3(178.02±8.13beat/min), followed by G4(174.62±9.16beat/min) also there&quot;s a remarkable difference was found (P＜0.001).<BR>&nbsp;&nbsp;5. The maximal O2 pulse was record as order of G2(25.26±6.87), followed by G4(24.07±2.74), followed by G1(20.13±4.47), followed by G5(19.39±2.33), followed by G3(15.01±1.88) and showed reliable difference(P＜0.001).<BR>&nbsp;&nbsp;6. The maximal oxygen uptake was record as order of G2(4315.45±1175.89㎖/min), followed by G4(4110.00±372.62㎖/min), followed by Gl(3556.58±412.24㎖/min), followed by G5.3(3442.45±335.09㎖/min), followed by G3(2604.91±242.88㎖/min) and showed reliable difference(P＜0.001).<BR>&nbsp;&nbsp;7. The maximal ventilation of carbon dioxide(？CO₂) was record as order of G4(5877.69±728.60㎖/min), G2(5796.05±1582.40㎖/min), G1(4873.05±600.09㎖/min), G5(4497.95±569.49㎖/min), G3(3541.36±435.57㎖/min) and showed reliable difference(P＜0.001).<BR>&nbsp;&nbsp;8. The maximal rate of gas exchange was record as order of G4(1.88±0.82) followed by G5(1.78±0.10) followed by G1(1.69±0.27) followed by G3(1.61±0.11) followed by G2(1.51±0.10) and showed reliable difference(P＜0.05).<BR>&nbsp;&nbsp;9. The maximal oxygen uptake of maximal was appeared as G2(59.82±14.40㎖/㎏/min), followed by G4(52.39±4.13㎖/㎏/min), followed by G1(48.97±5.01㎖/㎏/min), followed by G5(46.23±2.89㎖/㎏/min), followed by G3(41.75±3.38㎖/㎏/min) also theres a remarkable difference was found (P＜0.001).<BR>&nbsp;&nbsp;By above data we reached some conclusion as follows. Except for the respiration rate, the maximal value in the state of exercise revealed the reliable difference between those groups, and cardiovascular function was recorded as order of G2, G4, G1, G5, G3, but in case of gas exchange did not.
