Regular physical activity (PA) decreases the risk of comorbidities associated with a sedentary lifestyle in individuals with intellectual disabilities (IDs). They also may experience additional barriers that may prevent PA, including access, proper instruction and support. At-home PA programming is a feasible alternative to long-term adherence. This study aimed to determine (1) how an at-home DVD programme affects PA adherence and (2) the extent to which caregiver support influences PA.
Thirty-one adolescent or adult-aged participants with mild or moderate ID were randomised into a DVD or control group exercise intervention. Participants were given autonomy to choose what type of PA modality from the intervention they would like to participate in. Caregiver support during the PA was also measured.
The two-way repeated-measures MANOVA demonstrated that the intervention DVD group was statistically significant, with a large effect size in PA minutes (P = 0.014, ηP = 0.236) and rate of perceived exertion (P = 0.002, ηP = 0.342) compared with the control group.
The findings demonstrated that using an adapted DVD increased PA minutes and the rate of perceived exertion without high levels of caregiver support.
规律的体育活动（PA）可降低智力残疾（ID）个体因久坐生活方式导致的合并症风险。他们可能还会遇到一些阻碍体育活动的额外障碍，包括机会获取、适当指导和支持。居家体育活动计划是实现长期坚持的一种可行选择。本研究旨在确定：（1）居家DVD计划如何影响体育活动的坚持情况；（2）照顾者支持对体育活动的影响程度。
31名轻度或中度智力残疾的青少年或成年人被随机分为DVD组或对照组进行运动干预。参与者可自主选择他们想参与的干预中的体育活动类型。同时还测量了体育活动期间照顾者的支持情况。
双向重复测量多变量方差分析表明，与对照组相比，干预DVD组在统计学上具有显著意义，在体育活动时长（P = 0.014，ηP = 0.236）和自觉用力程度（P = 0.002，ηP = 0.342）方面有较大效应量。
研究结果表明，使用经过改编的DVD可增加体育活动时长和自觉用力程度，且无需照顾者的高度支持。
