The purpose of this research is to examine the impact of hydraulic fitness exercises on some physical parameters and body perception of the middle aged sedentary women. A total of 60 women participated in the study voluntarily. Hydraulic station fitness exercises were administered for a duration of 12 weeks. Body weight, body mass index, body flexibility of the women and their body perception levels were determined. Statistically significant differences were found in the variable as follows, the weight (t=11.4, p<0.05), BMI (Body Mass Index) (t=3.29, p<0.05), BFP (Body Fat Percentage) (t=10.8, p<0.05), flexibility (t=-11.6, p<0.05), sit ups (t=-16.7, p<0.05), and body perception (t=-12.3, p<0.05). Weight gain was observed for women in the control group and decrease in flexibility and ability to do sit ups. However, a weight loss was observed for the women in the experimental group and it was determined and found that their BMI, flexibility and ability to do sit ups and even satisfaction of physical space improved positively.
