the effect of nordic walking on the galectin 3 and some new metabolic markers in elderly men with osteosarcopenic obesity

Background: sarcopenia is the age-related progressive loss of muscle mass and strength. the main symptom of the condition is muscle weakness. objectives: the aim of the present study was to determine the effect of 12 weeks of nordic walking on the expression of the cardiovascular biomarker galectin 3 gene and some new metabolic markers in elderly men with osteosarcopenic obesity. methods: twenty elderly men with a mean age of 60 to 80 years, who had osteosarcopenic obesity with a body mass index (equal to and above 30) and body fat percentage (equal to and above 30) participated in this research and they were randomly divided into 2 nordic walking training groups and a control group (10 people in each group). the nordic walking training program was implemented for 12 weeks and 3 days a week. the intensity of the exercises in each session was 50 to 75% of the maximum heart rate and the duration of each exercise session was 60 minutes. results: 12 weeks of nordic walking exercises caused a significant decrease in the circulating levels of galectin-3 (p = 0.001) and a decrease in the tyg-bmi index (p = 0.001) in the subjects. but there was no significant effect on the atherogenic index of plasma (aip) (p = 0.265) and tyg (p = 0.126) and tyg-bmi (p = 0.347) indices of the subjects. conclusions: nordic walking exercise plays an important role in reducing cardiovascular risks by reducing galectin 3 biomarker and atherogenic plasma index (aip).
