/The Improvement in Asthma, As Related to Physical Activity, Vitamins, and Antioxidant Loads/

This is an analysis of the journal article “Relationship Between Oxidative Stress, Physical Activity, and Vitamin Intake in Patients with Asthma,” by Yamasaki et al (2017).

What is the background to this research?
Oxidative stress plays an important role in the pathogenesis of bronchial asthma. Antioxidant nutrition and supplementation have been used to reduce oxidative stress. However, a clinical trial with antioxidant supplementation showed no beneficial effects in patients with asthma. On the other hand, physical activity is related to the prognosis of chronic obstructive pulmonary disease (COPD) and is also related to oxidant status. We investigated the relationships between oxidative stress, serum levels of vitamins, dietary vitamin intake, daily activities, and pulmonary functions in patients with asthma.

Where is the research from?
This research was conducted through the Tottori University Faculty of Medicine, in Yonago, Japan. The researchers who conducted this study have previously investigated the prevalence of asthma in Japan, with results showing approximately one in six children suffer from asthma.

The authors of this study have contributed to over 15,000 studies between them, in areas that include (but are not limited to) cardiopulmonary function and disease, gene expression, effects of nutrition on bodily functions and pathologies, physiological changes with exercise and microcellular and biochemical interactions.

The authors declare no conflict of interest with this study.

What kind of research was this?
This study was a short term observational study. The evidence from this study demonstrated a high level of correlation with other studies in this field.
