“…Many studies of adults, including older adults, have reported that carotenoid levels are positively related to physical performance [29,30]. Moreover, a previous study on Korean adolescents reported that blood carotenoid levels were positively related to physical performance [17].…”

“…Some observational evidence suggests that carotenoids are positively associated with physical performance [14−16]. Our previous study observed that blood carotenoid levels might be positively associated with physical performance in Korean adolescents [17]. It could be that the protective effect of carotenoids against oxidative damage promotes health and nutrition to elevate physical performance.…”

Background 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 cross-sectional study aims to investigate whether carotenoids modify the association between plasma malondialdehyde (MDA) and physical performance in Korean adolescents. Methods The study sample consisted of 381 participants (164 boys, 217 girls) aged 13−18, who participated in the 2018 National Fitness Award Project. We quantified α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, lycopene, and MDA levels in plasma using HPLC with photodiode array detection. Physical performance was measured by determining the absolute and relative hand grip strength, 20-m progressive aerobic cardiovascular endurance run, estimated maximal oxygen consumption, curl-up, and sit-and-reach. Results In boys, the multiple linear regression model adjusted for age, BMI, smoking, drinking, and physical activity showed that the MDA level was negatively associated with absolute hand grip strength; this association was observed only in groups with α-carotene, β-cryptoxanthin, zeaxanthin, and total carotenoid values below the median. Conclusion These results suggest that carotenoids may act as an effect modifier of the association between MDA and physical performance in Korean male adolescents.

“…This large-scale national project is currently managed by 21 centers [ 19 ]. Among the 450 adolescents in our previous study, which reported associations between carotenoids and physical performance [ 18 ], we excluded participants for whom we were unable to analyze MDA concentration due to insufficient blood samples ( n = 69). As a result, 381 participants (164 boys, 217 girls) aged 13–18 years were included in this study.…”

We quantified α-carotene, β-carotene, β-cryptoxanthin, lutein, zeaxanthin, lycopene, and MDA levels in plasma using HPLC with photodiode array detection. Among boys but not girls, plasma MDA level was negatively associated (β = −0.279, p = 0.0030) with total plasma carotenoid levels and marginally negatively associated (β = −0.907, p = 0.0876) with absolute hand grip strength. After adjustment for covariates in boys, the MDA level was negatively associated with absolute hand grip strength and relative hand grip strength; this association was observed only in groups with individual carotenoid and total carotenoid values below the median. These findings support a significant association between plasma MDA level and hand grip strength, and this association has been potentially modified by plasma levels of carotenoids in Korean male adolescents.

“…Height was measured to the nearest 0.1 cm using a stadiometer (Seca, Seca Corporation, Columbia, MD, United States). Body weight and percent body fat were measured using bioelectrical impedance analysis equipment (Inbody 720, Inbody, Seoul, Korea) ( Jeong et al, 2020 ). BMI was calculated by dividing body weight (kg) by height squared (m 2 ).…”

Estimation of Health-Related Physical Fitness Using Multiple Linear Regression in Korean Adults: National Fitness Award 2015–2019

Continuous health care and the measurement of health-related physical fitness (HRPF) is necessary for prevention against chronic diseases; however, HRPF measurements including laboratory methods may not be practical for large populations owing to constraints such as time, cost, and the requirement for qualified technicians. This study aimed to develop a multiple linear regression model to estimate the HRPF of Korean adults, using easy-to-measure dependent variables, such as gender, age, body mass index, and percent body fat. The National Fitness Award datasets of South Korea were used in this analysis. The participants were aged 19–64 years, including 319,643 male and 147,600 females. HRPF included hand grip strength (HGS), flexibility (sit and reach), muscular endurance (sit-ups), and cardiorespiratory fitness (estimated VO2max). An estimation multiple linear regression model was developed using the stepwise technique. The outlier data in the multiple regression model was identified and removed when the absolute value of the studentized residual was ≥2. In the regression model, the coefficient of determination for HGS (adjusted R2: 0.870, P < 0.001), muscular endurance (adjusted R2: 0.751, P < 0.001), and cardiorespiratory fitness (adjusted R2: 0.885, P < 0.001) were significantly high. However, the coefficient of determination for flexibility was low (adjusted R2: 0.298, P < 0.001). Our findings suggest that easy-to-measure dependent variables can predict HGS, muscular endurance, and cardiorespiratory fitness in adults. The prediction equation will allow coaches, athletes, healthcare professionals, researchers, and the general public to better estimate the expected HRPF.
