Purpose Many Korean college students suffer from physical inactivity and mental health problems. However, it has not been sufficiently reported how this lack of exercise and health-related behavior affect their health. The present study was performed to identify the relationships among physical activity level, health-promoting behavior, and physiological variables in Korean undergraduate and graduate students. Methods Participants were 115 undergraduate and graduate students from one university in Seoul. The Pearson's …

The purpose of the present work was both to analyze composition of Spanish celiac women and to study the food habits and gluten-free diet of these celiac patients, in order to determine whether they achieve a balanced and healthy diet as well as to highlight nutritional qualitative and/or quantitative differences. 54 adult celiac women (34±13 years) took part in the six-month study. Height, weight and body composition were measured. An analysis of energy consumption and of the macronutrient distribution of their diet was carried …

PURPOSE: The purpose of this study was to investigate the relationship of smartphone use time, sitting time, and fitness level in university students. METHODS: The participants of this study were 237 healthy university students (157 males and 80 females) enrolled from 2017 to 2018. The smartphone use time was divided into three groups: 0-4,≥ 4-10, and≥ 10 hours, as was the sitting time: 0-4, 4-7, and≥ 7 hours. Binary logistic regression was used to calculate the odd ratio (OR) and 95% confidence interval (CI) of the smartphone use time …

Psychological distress has a negative impact on employee health and work performance. However, there is a paucity of studies examining the effects of exercise on the psychological well-being of workers in the field of occupational health. In this study, we evaluated the benefits of a cognitive behavioral therapy (CBT)-based exercise program in reducing psychological distress among employees. A 10-week single-group study was conducted with employees aged 20 to 65 years who had no present or past serious medical illness …

Purpose Joint mobility is a fundamental part in physical activity program for children, but a scientific characterization of the methods to improve the articular mobility in healthy children is still poor. The aim of this study was to investigate whether joint mobility/muscular elasticity were related to a merely active lifestyle or could be significantly improved in the presence of a collective, easy-to-perform, but specifically designed and professionally guided program. Methods Specific functional and anthropometric parameters were single-blind tested on 277 …

This study investigated the physiological difference in recreational runners between a noncontinuous and a continuous endurance training protocol. It also aimed to determine physiological surrogate that could monitor metabolic demand of prolonged running in real‐time. For data collection, a total of 18 active male recreational runners were recruited. Physiological (HR, RR, RER, ṼO2, BL a), and overall perceptual (RPEO) responses were recorded against three designed test sessions. Session 1 included ṼO2submax test to …

High-intensity resistance training decreases central arterial compliance (CAC). Subendocardial viability ratio (SEVR) is a useful tool that reflects the balance between coronary perfusion and left ventricular afterload. Animal studies have demonstrated that decreased CAC is associated with SEVR deterioration. Therefore, resistance training-induced decrease in CAC may be associated with changes in SEVR. The objective of the present study was to investigate the association between SEVR and CAC using both cross …

We examined the changes in skin temperature before and after application of heat to abdominal regions of healthy volunteers. Eight healthy female subjects with no past history of disease were selected for this study. Time-dependent changes in skin temperature of the abdominal region were measured after 10, 20, and 30 min of heat stimulation using a digital infrared thermographic imaging device. Skin temperatures in the abdominal region significantly increased in a time-dependent manner after application of heat. In the resting …

The effect of a 12-week low-intensity resistance exercise programme with blood flow restriction (LI-BFR) on growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels in middle-aged women (52.7±7.8 years) was examined. Subjects (N= 44) were randomly assigned to the following five groups: control group (CG; n= 8), low-intensity (40% of 1RM) resistance exercise group (LI; n= 9), high-intensity (70% of 1RM) resistance exercise group (HI; n= 9), low-intensity (20% of 1RM) resistance exercise group with a 5% reduction in cuff …

This study examines the combined effects of caloric restriction on body composition, blood lipid, and satiety in slightly overweight women by varying food density and aerobic exercise. Twenty-three women were randomly assigned to one of two groups for a four-week weight management program: the high-energy density diet plus exercise (HDE: n= 12, 22±2 yrs, 65±7 kg, 164±5 cm, 35±4% fat) and low-energy density diet plus exercise (LDE: n= 11, 22±1 yrs, 67±7 kg, 161±2 cm, 35±4% fat) groups. Subjects maintained a low-calorie diet (1,500 …
