Regular physical activity is essential to improve and maintain physical and mental health. Moreover, physical inactivity is the leading preventable cause of many chronic diseases leading to higher rates of mortality. Physical activity levels begin to decline in adolescence and continue to decline with age. Beginning in childhood and continuing into college, women have been shown to spend much less time engaged in physical activity than men. More focus is needed on the physical activity patterns, motivation, intention, and experiences of females as they transition into college. This qualitative, interpretive research study explored experiences that contribute to physical activity behaviors of college females. Sixteen female college students from colleges and universities across the United States were purposefully selected to participate in this study. Data was collected through the participant's responses to demographic and open-ended interview questions using Zoom. The interview narrative recordings were transcribed verbatim, providing descriptions of physical activity experiences that were then analyzed and coded for themes. Findings revealed that these female college students are faced with many challenges that they perceive as barriers to getting enough physical activity in their day. Lack of time was perceived as the most common barrier, followed by motivation and knowledge. Engaging in their preferred choice of activity resulted in enjoyment, leading many of the participants to experience more intrinsic motivation. This is congruent with Deci & Ryan's (1985) Self-determination Theory, which suggests that an individual that is intrinsically motivated, due to the fulfillment of the three basic needs of autonomy, competence, and relatedness, will more likely adhere to the activity. It is suggested that numerous choices for diverse physical activity in college should be made available by the institutions, thus ensuring greater opportunities for these students to be intrinsically motivated.
