Self-reported physical activity (PA) is well associated with cardiorespiratory fitness and exercise capacity. The short International Physical Activity Questionnaire (IPAQ-short) is a frequently used instrument for cross-national assessments of PA in adults. The purpose of this study was to validate IPAQ-short against exercise capacity in Greek young adults.
One hundred and thirteen men and 105 women, aged 20-29 years, were randomly selected from a larger population of young health-science students. A Greek version of IPAQ-short (IPAQ-Gr) was administered to all participants before their exercise capacity evaluation with a maximal Bruce treadmill test. Multiple regression and correlation analyses were used to examine the associations between all IPAQ-Gr outcomes with exercise capacity based on maximal treadmill time.
Spearman's correlations for total and vigorous PA against maximal treadmill time were significant in all groups examined, ranging from 0.35 to 0.43. Moderate and walking PA correlations were poor and nonsignificant, ranging from near-zero values to 0.19. In multiple linear regression analysis, only sex, smoking, and vigorous PA from all personal and log-transformed IPAQ-Gr data were significantly associated with maximal treadmill time. Partial correlation analysis for the overall population, adjusted for sex and smoking, showed that total PA (r=0.37) and vigorous PA (r=0.47) were significantly associated with exercise capacity.
IPAQ-Gr was tested against exercise capacity and showed acceptable validity properties in Greek young adults. Total and vigorous weekly PA expenditure were well associated with exercise capacity, presenting significant validity correlations against maximal treadmill time.
自我报告的身体活动（PA）与心肺适能和运动能力密切相关。简短国际体力活动问卷（IPAQ-short）是成人PA跨国评估中常用的工具。本研究的目的是在希腊年轻成年人中验证IPAQ-short与运动能力的相关性。
从一大群年轻健康科学专业学生中随机选取113名男性和105名女性，年龄在20 - 29岁之间。在通过最大布鲁斯跑步机测试评估他们的运动能力之前，对所有参与者进行希腊版的IPAQ-short（IPAQ-Gr）测试。使用多元回归和相关分析来检查基于最大跑步机运动时间的所有IPAQ-Gr结果与运动能力之间的关联。
在所有检查的组中，总PA和剧烈PA与最大跑步机运动时间的斯皮尔曼相关性显著，范围从0.35到0.43。中等强度和步行PA的相关性较差且不显著，范围从接近零值到0.19。在多元线性回归分析中，来自所有个人和对数转换的IPAQ-Gr数据中，只有性别、吸烟和剧烈PA与最大跑步机运动时间显著相关。对总体人群进行性别和吸烟调整后的偏相关分析表明，总PA（r = 0.37）和剧烈PA（r = 0.47）与运动能力显著相关。
在希腊年轻成年人中，对IPAQ-Gr与运动能力进行了测试，结果显示其具有可接受的效度特性。每周总PA和剧烈PA消耗与运动能力密切相关，与最大跑步机运动时间呈现出显著的效度相关性。
