A program aimed at improving cardiovascular fitness was evaluated. This program involved 298 volunteer middle-aged participants who initially had a bicycle ergometry test to calculate fitness. Other measurements included body fat (estimated by skin fold measurements) and a rating of coronary-prone personality. The participants were given their results and then offered a six-week fitness class consisting of both didactic and exercise segments. After six months, bicycle ergometry was repeated. During this period, mean calculated maximum oxygen uptake (a measure of fitness with a "normal" range of 20 mL/kg/min to 60 mL/kg/min) improved from 38.0 to 39.6 mL/kg/min (t test, P = .0001). Classifying this according to a cardiovascular fitness rating based on age and sex, with 5 being excellent fitness to 1 being very poor fitness, the mean fitness rating went from 3.08 to 3.31 (t test, P = .0001). There was no change in weight or percentage of body fat. Both those who attended the fitness classes and those who did not attend improved equally. Those who did not attend classes had higher ratings on a coronary-prone personality scale compared with those attending classes. In some groups, it appears that significant improvement in cardiovascular fitness may be initiated with a five-minute, office-based bicycle test.
对一项旨在提高心血管健康水平的项目进行了评估。该项目有298名中年志愿者参与，他们最初进行了自行车测力计测试以计算健康水平。其他测量指标包括体脂（通过皮褶测量估算）和冠心病倾向人格评分。向参与者公布了他们的测试结果，然后为他们提供了一个为期六周的健身课程，课程包括教学和锻炼环节。六个月后，再次进行自行车测力计测试。在此期间，平均计算得出的最大摄氧量（衡量健康水平的指标，“正常”范围为20毫升/千克/分钟至60毫升/千克/分钟）从38.0毫升/千克/分钟提高到39.6毫升/千克/分钟（t检验，P = 0.0001）。根据基于年龄和性别的心血管健康评分进行分类，5分为优秀健康水平，1分为非常差的健康水平，平均健康评分从3.08提高到3.31（t检验，P = 0.0001）。体重和体脂百分比没有变化。参加健身课程的人和未参加的人改善程度相同。未参加课程的人在冠心病倾向人格量表上的评分高于参加课程的人。在一些群体中，似乎通过一项为期五分钟的办公室自行车测试可能会显著提高心血管健康水平。
