Positive influence of aqua exercise and burdock extract intake on fitness factors and vascular regulation substances in elderly

Health issues in elderly individuals are often complex and tend to lead to chronic diseases; such issues can be due to a decline in fitness resulting from lack of physical activity. Aqua exercise and burdock are positive effects on cardiovascular disease and vascular health. This study investigated the changes due to aqua exercise and burdock extract intake in senior fitness, prostaglandin I ₂ (PGI ₂ ), and thromboxane A ₂ (TXA ₂ ) in elderly women. Forty elderly women (65–80 years) volunteered for this study. After baseline measure ments, participants were randomized into control (n = 8), aqua exercise (n = 11), aqua exercise and burdock extract intake combi nation (n = 11), and burdock extract intake groups (n = 10). The variables of senior fitness tests, PGI ₂ and TXA ₂ were measured in all participants before and after the 12week study. Blood collec tions were carried out at the beginning and the end of aqua exercise training. Muscular strength, endurance, flexibility, and cardiorespiratory endurance of aqua exercise and burdock extract intake group at posttest significantly increased compared to pre test (p<0.05). There were no significant differences in PGI ₂ and TXA ₂ between pre and posttraining programs. In conclusion, our findings indicated that the aqua exercise and burdock extract intake improves senior fitness factors in elderly Korean women. Also, the program participation led to a balance between PGI ₂ and TXA ₂ . Additionally, burdock extract intake may be useful in vas cular health by playing a secondary role in disease prevention and health promotion.
