Swedish physical activity on prescription (PAP) is an evidence-based method to promote physical activity. However, few studies have investigated the effect of Swedish PAP on physical fitness, in which better cardiorespiratory fitness is associated with lower risks of all-cause mortality and diagnose-specific mortality. Direct measures of cardiorespiratory fitness, usually expressed as maximal oxygen uptake, are difficult to obtain. Hence, exercise capacity can be assessed from a submaximal cycle ergometer test, taking the linear relationship between heart rate, work rate, and oxygen uptake into account. The aim of this study was to evaluate exercise capacity in the long term, following PAP treatment with enhanced physiotherapist support in a nonresponding patient cohort. In total, 98 patients (48 women) with insufficient physical activity levels, with at least one component of the metabolic syndrome and nonresponding to a previous six-month PAP treatment, were randomized to PAP treatment with enhanced support from a physiotherapist and additional exercise capacity tests during a two-year period. A significant increase in exercise capacity was observed for the whole cohort at two-year follow-up (7.6 W, ≤ 0.001), with a medium effect size (r = 0.34). Females (7.3 W, = 0.025), males (8.0 W, = 0.018) and patients ≥58 years old (7.7 W, = 0.002) improved significantly, whereas a nonsignificant increase was observed for patients <58 years old (7.6 W, = 0.085). Patients with insufficient physical activity levels who did not respond to a previous six-month PAP treatment can improve their exercise capacity following PAP treatment with enhanced support from a physiotherapist during a two-year period. Future studies should include larger cohorts with a control group to ensure valid estimations of exercise capacity and PAP.
瑞典运动处方（PAP）是一种促进身体活动的循证方法。然而，很少有研究调查瑞典 PAP 对身体适应性的影响，而更好的心肺适应性与全因死亡率和特定诊断死亡率的降低相关。心肺适应性的直接测量，通常以最大摄氧量表示，难以获得。因此，可以从次最大的踏车测力计测试中评估运动能力，同时考虑心率、做功和摄氧量之间的线性关系。本研究旨在评估在增强物理治疗师支持的 PAP 治疗后，非应答患者队列中，长期的运动能力。共有 98 名（48 名女性）身体活动水平不足的患者，至少有一个代谢综合征成分，且对之前的六个月 PAP 治疗无反应，随机分为 PAP 治疗，增加物理治疗师的支持，并在两年期间进行额外的运动能力测试。在两年随访时，整个队列的运动能力显著增加（7.6W， ≤ 0.001），具有中等效应大小（r = 0.34）。女性（7.3W， = 0.025）、男性（8.0W， = 0.018）和年龄≥58 岁的患者（7.7W， = 0.002）显著改善，而年龄<58 岁的患者无显著改善（7.6W， = 0.085）。对之前的六个月 PAP 治疗无反应的身体活动水平不足的患者，在两年期间接受增强物理治疗师支持的 PAP 治疗后，可以提高其运动能力。未来的研究应包括更大的队列和对照组，以确保运动能力和 PAP 的有效估计。
