To analyze, both by a retrospective and prospective study design, the relationship of maximal oxygen consumption (VO2max) and physical activity (PA) to upper respiratory tract infections (URTI) symptomatology in elderly subjects.
61 (33 men and 28 women) healthy and weight-stable active elderly volunteers aged 66-84 yr participated in the study. PA was evaluated by a questionnaire QAPSE (Questionnaire d'Activite Physique Saint-Etienne) and expressed by two QAPSE activity indices: MHDEE (mean habitual daily energy expenditure) and sports activity (daily energy expenditure corresponding to leisure time sports activities). Log books for daily recording of URTI symptomatology were used in prospective design.
In a 1-yr retrospective study a significant correlation was found between number of weeks with URTI per year and Sports activity index (r = -0.27, P = 0.037). In a prospective 12-month follow-up, the number of episodes per year and number of days with URTI per year were significantly negatively associated with sports activity index (r = -0.29, P = 0.022 and r = -0.26, P = 0.041, respectively).
In healthy active elderly subjects the symptomatology of URTI over long periods of time is inversly related to energy expenditure utilized during moderately intensive physical exercise.
通过回顾性和前瞻性研究设计，分析老年受试者最大耗氧量（VO2max）和身体活动（PA）与上呼吸道感染（URTI）症状之间的关系。
61名（33名男性和28名女性）年龄在66 - 84岁之间、健康且体重稳定的活跃老年志愿者参与了该研究。通过圣艾蒂安身体活动问卷（QAPSE）对身体活动进行评估，并由两个QAPSE活动指数表示：平均每日习惯性能量消耗（MHDEE）和体育活动（对应休闲时间体育活动的每日能量消耗）。前瞻性设计中使用日志记录每日的URTI症状。
在为期1年的回顾性研究中，发现每年患URTI的周数与体育活动指数之间存在显著相关性（r = -0.27，P = 0.037）。在为期12个月的前瞻性随访中，每年的发作次数和每年患URTI的天数与体育活动指数显著负相关（分别为r = -0.29，P = 0.022和r = -0.26，P = 0.041）。
在健康活跃的老年受试者中，长期的URTI症状与中等强度体育锻炼期间的能量消耗呈负相关。
