Association between redox state of human serum albumin and exercise capacity in older women: A cross‐sectional study

Abstract: Aim Oxidative stress plays a key role in declining exercise capacity, which is one of the major health problems in old age. The redox state of human serum albumin (HSA) has been considered a biomarker reflecting oxidative stress; however, its relationship to exercise capacity in older people remains to be examined. We aimed to examine the redox state of HSA as a potential biomarker of exercise capacity in community‐dwelling older women. Methods We analyzed 125 women aged ≥75 years. Exercise capacity was evalua… Show more

“…However, this dietary supplementation had no effect on oxidized shift of serum ALB redox state after exercise training. A recent study by Ashikawa et al is notable as they elucidated a positive correlation between serum HMA ratio and exercise capacity, as evaluated by 6-min walk distance, in women aged ≥75 years [88]. This observation would substantiate the association between oxidative stress and frailty [89].…”

“…For example, high HNA levels were positively correlated with a thicker carotid intima-media thickness, and HNA itself may bind more pro-atherosclerotic lipid mediators 32 , 33 . Conversely, exercise as measured by the walking distance was negatively corrected with HNA levels 34 . Collectively, these reports and the present findings suggest that HNA is indeed significantly associated with the pro-atherosclerotic process.…”

“…There have been several reports of the association between f(HMA), a marker of oxidative stress, and chronic diseases [ 16 ]. However, few reports have indicated its association with motor function [ 33 ]. Furthermore, to our knowledge, this is the first study to report on the association between f(HMA) and LS.…”

“…It has been reported that oxidative stress is associated with chronic diseases, including hypertension, obesity, liver injury, renal function, anemia, and cardiovascular complications [ 30 ]. Furthermore, increased oxidative stress in the elderly might be associated with a deterioration in motor function as increased oxidative stress reduces walking speed in elderly women [ 33 ]. This study concurred, showing increased oxidative stress and reduced motor functions, such as grip strength and walking speed, in elderly people, which worsened the degree of impairment of locomotion.…”
