Final answer:
Intensity and enjoyment are two key factors that influence exercise participation and adherence. Individuals may prefer moderate-intensity activities that allow for conversation, or vigorous activities with limited speech. Enjoyable activities are more likely to be continued, offering additional mental health benefits.
Step-by-step explanation:
Two physical activity factors that influence exercise participation and adherence are intensity and enjoyment. Intensity refers to whether an exercise is moderate or vigorous. According to the 2018 Physical Activity Guidelines, adults should engage in at least 150 to 300 minutes of moderate-intensity aerobic activity per week, or 75 to 150 minutes of vigorous-intensity aerobic activity. The level of intensity can affect a person's ability to continue an activity, with some individuals preferring moderate activities where they can talk but not sing, while others may favor more vigorous activities that limit speaking to a few words without pausing for breath.
Enjoyment of physical activity is another critical factor in determining whether individuals will stick to an exercise routine. Finding an activity that is enjoyable is significant as it increases the likelihood of consistency in engaging in that activity. Whether it's dancing, gardening, or playing an activity-based video game, enjoying the chosen form of exercise can promote long-term adherence. Moreover, the mental health benefits of enjoying exercise are substantial as well, leading to reduced stress, improved body image, and positive self-esteem.
