바이아스론 선수의 최대산소섭취량과 무산소성역치 수준에 관한 연구

A study on the Vo₂ max and anaerobic threshold level of Biathlon athletes according to exercise load

&nbsp;&nbsp;The athletes were observed to the cardiorespiratory function of maximum exercise, to the step load when they were using treadmill.<BR>&nbsp;&nbsp;The other checking point were score, AT point, variations from the maximum, etc.<BR>&nbsp;&nbsp;The study resulted in as follows:<BR>&nbsp;&nbsp;1. In the time of maximum exercise load national Biathlon team have All-out time 15.21±1.93min, HR 193.38±7.84beats/min, ？&lt;SUB&gt;E&lt;/SUB&gt; 124.49±17.60ℓ/min, PR 55.00±6.50f/min, TV 2.75±0.37 ℓ/f, ？O₂4.51±0.67 ℓ/min, ？CO₂, 5.01±0.57 ℓ/min, RQ 1.16±0.04, ？O₂/W 70.21±4.43㎖/㎏min, O₂, pulse 24.47±3.52㎖/㎏/beats.<BR>&nbsp;&nbsp;2. The score of AT-point is as follows: AT point to All-out, time of National team 9.58±1.17min(63.72%), AT-HR max 176.00±10.07beats/min(91.00%), AT-？&lt;SUB&gt;E&lt;/SUB&gt; max 93.40±24.55 ℓ/min(74.79%), AT-？O₂ max 4.07±0.76 ℓ/min(89.96%), AT-？CO₂ max 4.09±0.70 ℓ/min(81.29%), AT-ℓ ？O₂/W max 63.19±5.43㎖/㎏/min(89.96%), AT-O₂ pulse max 23.07±3.53㎖/㎏/beats(94.58).<BR>&nbsp;&nbsp;3. The correlation between HR max and AT-HR max point, National team have a high correlation r=+0.80(p＜0.05), ？&lt;SUB&gt;E&lt;/SUB&gt; max and AT-？&lt;SUB&gt;E&lt;/SUB&gt; max point r=0.82(p＜0.05) have a high correlation, ？O₂ max and AT-？O₂ max point r=+0.98(p＜0.001) have a very high correlation, ？CO₂ max and AT-？CO₂ max point r=+0.93(p＜0.001) have very high positive correlation, ？O₂/W max and AT-？O₂/W max point r=+0.84(p＜0.01), O₂ pulse max and AT-O₂, pulse max point r=+0.98(p＜0.001) have a very high correlation.
