The expression of "lifestyles" describes a frame of expressed behaviours, usually in the form of patterns of consumption, that defines how an individual or social group fits into society. It presents as a focus of interest by researchers in this field, who classically favour the study of alcohol consumption, tobacco, eating habits and physical activity. The aim of this study was to identify the relationship between physical activity and healthy lifestyles, especially in terms of eating habits, tobacco, alcohol consumption, resting habits and resting heart rate in Health Sciences first-year students. A total of 177 students of both genders participated, of which 31 (17.5%) were male and 146 (82.5%) were female, with a mean age of 20.20 years, from 18 to 30 years. The data collection instrument used was the Healthy Lifestyle Questionnaire (EVS), using S.P.S.S. 21.0 for descriptive statistics and the Cronbach's alpha to evaluate the internal consistency of the questionnaires. A level of significance was adopted with a margin of error of 5% for a probability of at least 95% using the Kolmogorov-Smirnov technique and Mann-Whitney test for comparisons between practitioners’ students and genders. The results obtained demonstrate more favourable results in all variables in students practicing physical activity with significant differences in eating habits and Resting Heart Rate. In terms of gender there were significant differences in all variables except for eating habits. We conclude that physical activity students present more favourable results in terms of lifestyles combined with lower Resting Heart Rate values considered as positive factors in terms of quality of life. info:eu-repo/semantics/acceptedVersion
