Background: Childhood fitness is generally evaluated by a battery of health-related estimators to assess pediatric health status. More so than the fitness level at any other stage of life, the level of physical fitness in childhood will have a marked effect on an individual's physical development and overall health in adolescence and adulthood. This paper contributes to this issue by investigating the differences in the distribution of the physical fitness of elementary schoolchildren aged 9-12 by gender, region and ethnicity.
Methods: Data were drawn from a nationwide dataset of physical fitness test profiles of elementary school students, conducted by the Ministry of Education in Taiwan in 2008. In total, 134,546 schoolchildren in fourth to sixth grade aged from 9 to 12 were included. Three components of physical fitness are measured: explosive power; muscle strength; and flexibility. Each fitness test was carried out by the school teachers during physical education classes. A statistical test procedure was then used to test the distribution differences in each category of physical fitness by age, gender and region. By further using the official recommended levels, the proportions of schoolchildren who have poor physical fitness performance were also examined.
Results: In general, boys have better physical fitness than girls except in the area of flexibility. In addition to gender differences, the present results are supportive of there being differences in the rural and urban populations. The rural children perform better than urban children in bent-leg curl-ups and standing long jump tests.
Conclusions: Physical fitness has been recognized not only as an integrated predictor of the body's functional status, but also as an important marker of health outcomes. Although considerable attention had been paid to examining the urban-rural differences in physical fitness, it is necessary to further consider the differences in ethnicity.

Background/objectives: recent studies have suggested that components typical of the Mediterranean diet (MedDiet) are associated with depression and anxiety prevention. In this sense, the main objective of this study was to analyse the associations between adherence to the MedDiet and depression and anxiety symptoms and to examine whether this relationship is mediated by lean mass and the muscle strength index (MSI).
Methods: a cross-sectional study (based on data obtained from the Nuts4Brain-Z study) was conducted from 2023-2024, involving 428 university students, aged 18-30 years, from a Spanish public university.

Objective: In treating obesity, energy intake control is essential to avoid exceeding energy expenditure. However, excessive restriction of energy intake often leads to resting energy expenditure (REE) reduction, increasing hunger and making weight loss difficult. This study aimed to investigate whether providing nutritional guidance that considers energy expenditure based on the regular evaluation of REE and physical activity could effectively reduce body weight (BW) in patients with obesity.

Introduction: Gait analysis is a vital tool in the assessment of human movement and has been widely used in clinical settings to identify potential abnormalities in individuals. However, there is a lack of consensus on the normative values for gait metrics in large populations. The primary objective of this study is to establish a normative database of spatiotemporal gait metrics across various age groups, contributing to a broader understanding of human gait dynamics.
