Arterial stiffness expressed as brachial-ankle pulse wave velocity and gait assessment independent of lower extremity strength: a cross-sectional study in the older men population.

Background: Older men are more vulnerable to fatal falls than women, and gait disturbances contribute to the risk of falls. Studies have assessed the association between arterial stiffness and gait dysfunction, but the results have been inconclusive. This study aimed to conduct a cross-sectional analysis to evaluate the association between brachial-ankle pulse wave velocity (baPWV) and gait assessment in older men.

However, data on the association between flexibility and arterial stiffness in the older adult population are limited.

Association of Plasma Carotenoid and Malondialdehyde Levels with Physical Performance in Korean Adolescents.

Increased oxidative stress has been shown to lead to muscle damage and reduced physical performance. The antioxidant mechanism is most likely to reduce these relationships, but in the context of the action of carotenoids, more research is needed. This study aimed to investigate whether carotenoids modify the association between plasma malondialdehyde (MDA) and physical performance in Korean adolescents.

Development of Guidelines on the Primary Prevention of Frailty in Community-Dwelling Older Adults.

Association Between Diet Quality and Cardiorespiratory Fitness in Korean Adults: The 2014-2015 National Fitness Award Project.

Cardiorespiratory fitness (CRF) is a strong and meaningful indicator for predicting mortality, including cardiovascular disease, as well as simple physical capacity. Healthy eating is thought to be one of the crucial factors associated with an individual's CRF status, although little research has been done on the relationship between healthy eating and CRF. This study aimed to investigate the association between overall diet quality and CRF among Korean adults.

Association of Carotenoids Concentration in Blood with Physical Performance in Korean Adolescents: The 2018 National Fitness Award Project.

Adolescent physical performance is not only dependent on exercise but also on the role of antioxidants obtained through a healthy diet. However, few studies have specifically identified the relationship between carotenoids, a common antioxidant, and physical performance. This cross-sectional study aims to investigate the association between the level of carotenoids in the blood and physical performance among Korean adolescents aged 13 to 18 years.

Evidence-Based Optimal Cutoff Values with the Validation of Criterion-Referenced Standards for Sarcopenic Elderly Fitness Improvement.

Reference Values for Cardiorespiratory Fitness in Healthy Koreans.

We investigated reference values for cardiorespiratory fitness (CRF) for healthy Koreans and Koreans with coronary heart disease (CHD) and used them to identify inter-ethnic differences in CRF, differences over time in CRF, and differences in CRF between the healthy population and patients with CHD. The study population for healthy Koreans was derived from the database of KISS FitS (Korea Institute of Sports Science Fitness Standards) between 2014 and 2015. The study population for Koreans with CHD was derived from the database of the Korea University Guro Hospital Cardiac Rehabilitation Registry between June 2015 and December 2018.

Characterization and Validation of an "Acute Aerobic Exercise Load" as a Tool to Assess Antioxidative and Anti-inflammatory Nutrition in Healthy Subjects Using a Statistically Integrated Approach in a Comprehensive Clinical Trial.

The homeostatic challenge may provide unique opportunities for quantitative assessment of the health-promoting effects of nutritional interventions in healthy individuals. . The present study is aimed at characterizing and validating the use of acute aerobic exercise (AAE) on a treadmill at 60% of VO for 30 min, in assessing the antioxidative and anti-inflammatory effects of a nutritional intervention.

Association of Diet Quality with Low Muscle Mass-Function in Korean Elderly.

There is a growing body of evidence that links nutrition to muscle mass and function in the elderly, suggesting that it has an important role to play both in the prevention and management of age-related sarcopenia. Some nutrients have been studied, but less is known about the influence of overall diet quality on the loss of skeletal muscle mass and function. This study investigated the interrelationship between the recommended food score (RFS), as an indicator of overall diet quality, and muscle mass function among the Korean elderly.

Association of recommended food score with depression, anxiety, and quality of life in Korean adults: the 2014-2015 National Fitness Award Project.

Background: A healthy diet is a key determinant of an individual's health status and is closely related to mental health and quality of life (QoL); however, the exact nature of the relationship is unknown. This study hypothesized that a higher diet quality score is associated with a lower observance of symptoms of depression and anxiety and a higher QoL.

Methods: This study evaluated 1,295 adults (521 men; 774 women) aged 19-64 years, who participated in the 2014-2015 National Fitness Award Project.
