RESUMEN

The bulk of research on microfiltered seawater (SW) is based on its short-term effects. However, the long-term physiological adaptations to combining SW and resistance training (RT) are unknown. This study aimed to analyse the impact of an RT program using elastic bands combined with SW intake on hepatic biomarkers, inflammation, oxidative stress, and blood pressure in post-menopausal women. Ninety-three women voluntarily participated (age: 70 ± 6.26 years; body mass index: 22.05 ± 3.20 kg/m2; Up-and-Go Test: 6.66 ± 1.01 s). RT consisted of six exercises (32 weeks, 2 days/week). Nonsignificant differences were reported for hepatic biomarkers except for a reduction in glutamic-pyruvic transaminase (GPT) in both RT groups (RT + SW: p = 0.003, ES = 0.51; RT + Placebo: p = 0.012, ES = 0.36). Concerning oxidative stress, vitamin D increased significantly in RT + SW (p = 0.008, ES = 0.25). Regarding inflammation, interleukin 6 significantly decreased (p = 0.003, ES = 0.69) in RT + SW. Finally, systolic blood pressure significantly decreased in both RT groups (RT + placebo: p < 0.001, ES = 0.79; RT + SW: p < 0.001, ES = 0.71) as did diastolic blood pressure in both SW groups (RT + SW: p = 0.002, ES = 0.51; CON + SW: p = 0.028, ES = 0.50). Therefore, RT + SW or SW alone are safe strategies in the long term with no influences on hepatic and oxidative stress biomarkers. Additionally, SW in combination with RT positively influences vitamin D levels, inflammation, and blood pressure in older women.

RESUMEN

PURPOSE: Serum vitamin D deficiency has been associated with frailty in people aged 65 and over, however its relationship with functional impairment has not been investigated in octogenerian (aged 80-90 years) institutionalized women. METHODS: We assessed functional impairment in this latter group by measuring frailty syndrome and other geriatric and psychological assessment scales: the Tinetti gait and balance index to determine the risk for falls, the Barthel index to measure the basic activities of daily living, the Lawton index for instrumental activities, the mini-mental score examination test for cognitive impairment, the Yesavage scale for geriatric depression, and the Norton scale for the risk of ulceration. RESULTS: Frail individuals had significantly reduced serum vitamin D concentrations (measured as total 25-hydroxyvitamin D; 25(OH)D) compared to robust individuals, but reduced 25(OH)D concentration did not significantly correlate with frailty syndrome severity, and mean 25(OH)D concentrations were within the recommended levels in all groups. The 25(OH)D concentration did not correlate with any of the blood analytical parameters measured and with the geriatric assessment scales used, suggesting a selective relationship with frailty. CONCLUSION: These results highlight the need to individualize treatment such as vitamin D supplementation in order to treat frailty syndrome.
