Background. Lack of movement activity in a person can lead to a decrease in physical fitness. There are many factors that affect physical fitness, one of which is smoking. Smoking has become a lifestyle in some developing countries, including Indonesia. The habit of smoking is easily found in various environments, including students. Therefore, researchers want to conduct further research to find the association between smoking habits and physical fitness in male aged 18-22 years at Udayana University. Method. This research is a cross sectional method. The research subjects were males aged 18-22 years totaling 95 people. The research was conducted in direct and indirect ways. The direct way is used to measure the physical fitness of the respondents using the Multi Stage Fitness Test (MSFT). The indirect way (questionnaire) is used to determine the level of smoking habits of respondents. The research will be conducted at Udayana University for 3 months starting from January to March 2024. Result. The results showed that 33 samples (34.7%) smoked with low intensity, 20 samples (21.1%) smoked with moderate intensity, and 42 samples (44.2%) smoked with high intensity. Based on MSFT, 41 samples (43.2%) had very poor physical fitness, 37 samples (38.9%) had poor physical fitness, and 17 samples (17.9%) had good physical fitness. This study showed a weak association between smoking activity and physical fitness (p = 0.01; r = -0.376). Conclusion. The conclusion in this study is that there is a significant association between smoking habits and physical fitness in males aged 18-22 years at Udayana University with a value of p = 0.01. The correlation coefficient shows -0.376 which means there is a weak association between smoking activity and physical fitness. The minus value shows an inversely proportional association between smoking activity and physical fitness where if there is an increase in smoking frequency, the level of physical fitness will decrease.
