56名45～60岁知识分子(52.2±4.9岁,男29名、女27名)接受了自行车功率计通气阈测定,男子每分钟递增15W,女子每分钟递增10W,持续增加负荷,直至强度达自身年龄预测最大心率的85％。结果表明,本文中男性(n=28)和女性(n=22)VO_2-T(vent)分别为1.12±0.231/min和0.85±0.191/min;Mets-T(vent)分别为4.7±0.74mets和4.24±0.8mets;P-T(vent)分别为75±20.31W和45 18.19W;P/kg-T(vent)分别为1.11±0.27W和0.75±0.29w;男、女性之间各数值均有显著性差异。提示采用适当的负荷强度和程序、通气阈测定可以成功地应用于康复体疗心肺机能测定。
Fifty-six intellectuals aged 45-60 (52.2 ± 4.9 years old, 29 males and 27 females) underwent a bicycle power meter ventilation threshold test. Men increased by 15 W per minute and women increased by 10 W per minute, continuing to increase the load until strength reached 85% of the maximum heart rate predicted by their age. The results showed that VO_2-T (vent) in male (n = 28) and female (n = 22) was 1.12 ± 0.231 / min and 0.85 ± 0.191 / min in male and in Mets-T (vent) And 4.24 ± 0.8mets respectively; PT (vent) was 75 ± 20.31W and 45 18.19W respectively; P / kg-T (vent) was 1.11 ± 0.27W and 0.75 ± 0.29w respectively; Significant difference. Prompt use of appropriate load intensity and procedures, ventilation threshold determination can be successfully used in rehabilitation physical therapy heart and lung function test.
