The development and maintenance of excess body mass in many children is partly attributable to levels of physical activity that are lower than the recommended 60 minutes/day. Walking is a recommended form of physical activity for obese children, due to its convenience and perceived ease of adoption. Unfortunately, studies that have used objective physical activity assessment continue to report low step counts and levels of physical activity in obese children. This may be due to physiological and/or biomechanical factors that make walking more difficult for obese children. The purpose of this review is to highlight the current recommended and measured levels of physical activity for children and to discuss the physiological and biomechanical challenges of walking for obese children that may help explain why these children are not meeting physical activity goals.
许多儿童超重的形成和维持部分归因于体力活动水平低于建议的每天60分钟。步行是肥胖儿童建议的一种体力活动形式，因为它方便且人们认为易于采用。不幸的是，使用客观体力活动评估的研究持续报告肥胖儿童的步数少且体力活动水平低。这可能是由于生理和/或生物力学因素，使得肥胖儿童行走更加困难。本综述的目的是强调当前建议的和实测的儿童体力活动水平，并讨论肥胖儿童行走时面临的生理和生物力学挑战，这些挑战可能有助于解释为什么这些儿童未达到体力活动目标。
