To assess perceptions of the intensity of specific physical activities in urban Indians and to determine whether these perceptions are dependent on age, gender, body mass index and actual physical patterns.
A self-administered questionnaire in a convenience sample of 782 adults (441 women) aged 17 to 70 years in the city of Bangalore.
Women rated the intensity of carpentry, jogging, manual labour and walking uphill significantly higher than men. These differences persisted when they were adjusted for total daily physical activity levels and levels of discretionary exercise. In contrast, while men rated household activities such as manual washing of clothes and sweeping at higher levels than women, these differences disappeared when they were adjusted for actual levels of daily activity related to household chores. There were clear age-related changes in the perception of intensity of physical activities and these persisted even after adjustment for overall physical activity patterns.
This study demonstrates clear age and gender-related differences in the perception of physical activities. This is important to know while motivating individuals to change physical activity patterns and assumes added importance given the recent evidence that perceived intensity of habitual activity is predictive of coronary heart disease, even at levels of activity that are below standard recommendations.
评估印度城市居民对特定体育活动强度的认知，并确定这些认知是否取决于年龄、性别、体重指数和实际身体活动模式。
在班加罗尔市对782名年龄在17至70岁的成年人（441名女性）进行便利抽样，采用自填式问卷。
女性对木工、慢跑、体力劳动和上坡行走强度的评分显著高于男性。在根据每日总身体活动水平和自由锻炼水平进行调整后，这些差异依然存在。相比之下，男性对诸如手洗衣服和扫地等家务活动强度的评分高于女性，但在根据与家务相关的实际日常活动水平进行调整后，这些差异消失了。在对体育活动强度的认知方面存在明显的年龄相关变化，即使在根据总体身体活动模式进行调整后，这些变化依然存在。
本研究表明在对体育活动的认知方面存在明显的年龄和性别差异。在激励个体改变身体活动模式时，了解这一点很重要，鉴于最近有证据表明，即使在低于标准建议的活动水平下，习惯性活动的感知强度也可预测冠心病，这一点就显得尤为重要。
