A universal approach to characterizing sport-related physical activity (PA) types in sport settings does not yet exist. Young adults (n = 30), 19-33 years, engaged in a 15-min activity session, performing warm-ups, 3-on-3 soccer, and 3-on-3 basketball. Videos were recorded and manually coded as criterion PA types (walking, running, jumping, rapid…

Objective: To systematically review and synthesize all relevant literature to assess the range of average daily sedentary time (ST) of undergraduate students enrolled in university and college programs across the world. Methods: Published, peer-reviewed articles were included if they: (1) were in English; (2) had a study population that consisted…

The aim was to establish which postural and physical activity outcomes are comparable across different accelerometer brands worn on the thigh when processed using open-source methods. Twenty participants wore four accelerometers (Axivity, ActiGraph, activPAL, GENEActiv) for three free-living days. Postural and physical activity outputs (average…

Despite proprietary algorithms to account for differences, output from activity trackers worn on different wrists may not be comparable because individuals vary in their reliance on each hand during free-living activities. Participants (n = 48) wore Fitbit Flex or Flex2 monitors on each wrist for three days. T tests, equivalence tests, and…

Objective: This study investigates the relationship between fitness tracker users' communication of exercise information and their exercise intentions and behaviors among college students. Participants: Data were collected from 186 undergraduate students. Methods: A quantitative online survey was conducted. Descriptive norm (perceptions of…

In spite of the fact that physical activity is inevitable in sustaining health, there are more people in the world who do not take it into account than who do. A growing number of young adults have been using wearable activity trackers, particularly step counts, to keep an eye on their health in the past few years. In an online survey university…

Most adults fail to meet recommended physical activity (PA) guidelines. PA tracking technologies may help increase activity because they facilitate self-monitoring and self-regulation. In response to recent calls for testing the effectiveness of these technologies, this study surveyed opinions of Fitbit users within a university setting.…

Background: Research has elucidated some harmful aspects of fitness wearable devices including their role in exacerbating disordered eating and exercise behaviors in young adults. Purpose: The purpose of this study was to examine 1) if use of wearables was associated with exercise dependence and 2) prevalence of compensatory behaviors (CB) in…

Background: Nearly half of all college students do not engage in the recommended amount of physical activity which may contribute to chronic diseases such as obesity. Purpose: To investigate college students' use and perceptions of wearable fitness trackers (WFTs) and the impact on confidence and motivation for increasing physical activity.…

Background: Young adults are adopting wearables ahead of research. Purpose: The purpose of this study was to explore the use of trackers through Social Cognitive Theory (SCT). Methods: SCT-guided individual interviews were conducted with young adults (n = 57). Typical case sampling was used to recruit college students (n = 35) and straight-to-work…

Purpose: The study aimed to determine the validity of the Fitbit Charge 2 (FC2) for measuring PA steps in college physical education settings using the Yamax SW-200 (YX) as the criterion device. Methods: Undergraduate students (n = 17) worn both FC2 and YX in two conditions (i.e., controlled and college physical education settings). The absolute…

Activity trackers (ATs) equipped with biometric sensors may support deep knowledge acquisition of health and active learning. The mechanism may be via personal data being pushed to the students, which deepens the knowledge about their own health and may impact long-term health action processes. To understand health knowledge acquisition, 43…

Digital technologies are now considered important in shaping young people's engagement in and with health and physical activity. Recent discussions show that the use of digital technologies to track health and fitness may over-emphasize the linear understanding of the body and health generally underpinned by Western health ideologies such as…

Weight-related teasing is associated with reduced levels of physical activity in youth, but the importance of weight teasing experiences to the engagement of female college students in physical activity is yet to be determined. Thus, this study examined differences in physical activity engagement and physical activity enjoyment in female college…

Objective: This study took the form of an intervention examining change in physical activity and quality of experience among students in an introductory health course who were asked to wear a Fitbit activity monitor throughout the semester. Method: College students (N = 56) took part in this controlled trial. Students enrolled in an introductory…
