The Effect of Deep Aquatic Training Supported by Nutritional Guidance on Vital Capacity, HbA1c, and Physical Efficiency in Individuals with Type 2 Diabetes Aged 40–45

The research problem lies in the high levels of glycated hemoglobin (HbA1c) and the weakness of some functional and physical indicators in individuals with type 2 diabetes. Some of these individuals also experience difficulty continuing traditional exercise, necessitating the search for safe and effective training methods that contribute to improving their health. The research aimed to develop a deep-water training program supported by nutritional guidelines and to identify its effect on improving vital capacity (FVC), reducing HbA1c levels, and developing physical efficiency in men with type 2 diabetes aged 40–45 years. The researcher used a pre-experimental with a single group pre-test and post-test. The research sample included six men with type 2 diabetes. The training program was implemented for eight weeks, with three sessions per week, totaling 24 training sessions, along with accompanying nutritional guidelines. The results presented according to the data notable contrasts related to the post-test throughout all of the research factors. Vital capacity increased from 3.88 liters to 4.77 liters, a 22.94% improvement, while HbA1c levels decreased from 7.00% to 6.30%, a 10.00% improvement. Physical fitness also increased from 63.32 to 74.23, a 17.23% improvement. The researcher determined that deep-water aquatic training supported by nutritional guidance can effectively enhance the respiratory function, lowered HbA1c levels, and improved physical fitness in men with type 2 diabetes.These findings align with Sustainable Development Goal 3 (good health and well-being) by promoting health, reducing the impact of chronic diseases, and improving quality of life.
