Staying physically active is synonymous with good health and well-being, and its benefits on the health of people with intellectual disabilities (PWIDs) have been studied. However, there is a lack of information on how it can influence their quality of life (QoL). This study aimed to analyze the relationship between QoL and physical activity in PWIDs according to gender and the characteristics of the practiced activity. A questionnaire was administered to 380 PWIDs (mean age of 28.23 ± 12.53), 54.21% of which were men. The QoL dimensions and second-order factors were studied in relation to practicing physical activity, the practice type, the context, and gender. The results indicate that people who practiced any activity showed better QoL values. Those who engaged in a nonregulated physical activity had better values in self-determination, emotional well-being, social inclusion, and personal development, while those who did sports presented higher scores in interpersonal relationships and physical well-being. In addition, it also appears that the association between physical activity and the QoL dimensions is distinct in inclusive and specific contexts. In conclusion, physical activity is related to a better QoL, although the impact of the practice type and context differs for each QoL dimension.
