不同體重次方探討相對最大攝氧量與耐力跑能力的相關研究

Abstract

目的：為了澄清相對最大攝氧量與耐力跑能力之間的關係，假設相對最大攝氧量與耐力跑能力之公式：VO2max ∙M^-b= f ∙v + c(由VO2max = a ∙M^b推導)成立，我們可以根據耐力跑能力(V)調整指數b ,以修正過去的相對最大攝氧量的計算公式，如此將能藉由修正指數b 後的相對最大攝氧量來推論耐力跑能力(FFM的指數b也做同樣的調整)。 方法：受試者為30名大專男子運動員(年齡21.5±2.83歲、身高173.9±3.35 公分、體重63.2±4.61 公斤)，其中十五人為為中長跑運動員，其他十五人非中長跑運動員。在本研究中，我們利用Lamb protocol來評估最大攝氧量，並且以Inbody2.0來測量身體組成，並且在室外的400公尺跑道接受1600公尺以及12分鐘跑走的測試。最後將實驗數據(最大攝氧量、體重與耐力跑速度)帶入VO2max ∙ M^-b = f ∙ v + c公式。經由成冪迴歸分析可得到最適合此方程式的指數b。 結果：實驗結果顯示：1)對於耐力較佳的運動員其最適的體重與去脂體重次方b各為0.9(R2 = .56)與0.76(R2 = .58)；2)對於優秀中長跑運動員其最適的體重與去脂體重次方b各為0.8(R2 = .61)與0.68(R2 = .62)。 結論：利用這些修正後的方法，運動員將更了解他們的耐力跑能力，為了評估耐力較佳的運動員的耐力跑能力，我建議利用M^0.9 與 FFM^0.76 來計算相對最大攝氧量；評估中長跑運動員的耐力跑能力，我建議利用M^0.8 與 FFM^0.68 來計算相對最大攝氧量。Purpose: To clarity the relationship between relative maximal oxygen uptake and the endurance running capacity, the model VO2max ∙ M^-b = f ∙ v + c(modify from VO2max=a ∙ M^b) is assumed. We adjust b according to the endurance running capacity, and then we may modify conventional calculation of relative VO2max. In this way, we infer endurance running capacity from relative VO2max by considering the power b of the body mass (we have a same analysis with FFM). Methods: Subjects are 30 college male athletics (21.5±2.83 yrs, 173.9±3.35 cm, 63.2±4.61 kg). Fifteen of the subjects are middle-long distance athletics and the others are not. In this study, we estimate relative VO2max by Lamb protocol and the body composition by Inbody2.0. They performed 1600m and 12min running test on an outdoor 400m track. The obtained data (VO2max, the body mass and the velocity of running test) are applied to VO2max ∙ M^-b = f ∙ v + c. By power regression we found the power b which matches the equation best. Results: The present data indicate that: 1) the most suitable power b of body mass and FFM for highly endurable athletics are 0.9 (R2 = .56) and 0.76 (R2 = .58), respectively; 2) for elites middle-long distance athletics are 0.8 (R2 = .61) and 0.68(R2 = .62). Conclusions: In these modified way, athletics will understanding more about their endurance running capacities. In order to evaluate endurance running capacity for highly endurable athletics, we suggest M^0.9 and FFM^0.76 for calculating relative VO2max; for elite middle-long distance runners, we suggest M^0.8 and FFM^0.68.
