of this article was to determine strength training practices and the intake of supplements by Polish Army soldiers. Attitudes toward physical fitness and the level of dietary knowledge among the soldiers were also examined. Methods. The soldiers (N=82) voluntarily participated in an anonymous survey. Results. The majority of participants take care of their bodies thanks to sport practice. They trained mainly 3–4 times a week. The results showed that the soldiers had good knowledge about strength training, and were aware that overtraining can induce dangerous consequences. All of the respondents regularly bought supplements because of their composition. Interestingly, no one reported buying creatine or free amino acids. Probably, the respondents were not aware that creatine is considered as the best, legal anabolic compound in use. The soldiers choose mainly protein and protein-carbohydrate supplements, mostly purchased in Internet shops (65%) and special nutrition shops (20%). During the training, most of the soldiers (90%) drank only natural, mineral water, and 10% used isotonic drinks. 40% of respondents compose the diet by themselves, using the Internet, and only 23% follow the advices of their coach. Conclusions. The presented research shows that soldiers in general are well informed that they need strength training and how to train. However, they should be better educated about how to supplement their diet.
