| Summary: | Physical inactivity and resultant chronic diseases of lifestyle (CDLs) are becoming a global epidemic as secular modernization and the sedentary lifestyles it brings with it become universal. The importance of physical activity (PA) in reducing morbidity and mortality from CDLs and related conditions has been well established. Since it is generally significant that the onset of many CDLs lies in childhood through to adolescence, preventative strategies should start as early in life as possible. Currently, university students are failing to engage in the levels of PA recommended for better health outcomes over the short and long term. To make matters worse, there is increasing evidence of a decrease in PA during the transitional phase from adolescence to adulthood. This study aimed to determine the physical activity (PA) levels, sedentary behaviour and health-related fitness (HRF) characteristics of female university students. In addition, the participants‘ perceived barriers to PA were investigated. The study was exploratory-descriptive and employed a quantitative research design. Five hundred and thirty-one full-time female students, between the ages of 18 and 46, studying at Nelson Mandela Metropolitan University‘s (NMMU) South, North, Second Avenue and Missionvale campuses participated in the study. The participants (n=531) completed an online survey which determined their PA levels, sedentary behaviours and perceived barriers to PA participation. A health-related fitness (HRF) assessment was also administered to 68 participants who completed the online survey. Their height, weight, and waist and hip circumferences were measured, as well as their cardiovascular fitness (CF). The majority (88 percent) of the participants reported low and minimal levels of PA, and 44 percent were either overweight or obese. The participants had a low-risk waist-to-hip ratio (WHR) (M=0.70). The majority of the population (94 percent) had poor cardiovascular fitness (CF). A high prevalence of sitting time was recorded among the participants: on average 855 minutes (14 hours) on a usual weekday and 720 minutes (12 hours) on a usual weekend day. Students reported the greatest length of sitting time at work/attending lectures/studying. Cross tabulations and Chi2 tests indicated no significant relationships among PA and HRF (BMI, WHR and CF) and sedentary behaviour and HRF. The ANOVA and t-test results for PA, sedentary behaviour and HRF related to various demographic variables, found small (0.19 < d < 0.50) and medium (0.49 < d < 0.80) significant differences by race (d=0.43; d=0.52), home language (d=0.41; d=0.44) and living arrangement (d=0.38; d=0.28). No significant relationship was found to exist between age, year of study and faculty of registration and sedentary behaviour or HRF. The participants listed: Not enough time; too expensive to exercise; and, no friends who can exercise with me as the most important barriers to participation in PA. Academic obligations (3.08 mean) was found to be the most important barrier to PA.
