Purpose The present study was conducted to compare the effects of low volume of high intensity interval training (LVHIIT) and high volume of high intensity interval training (HVHIIT) on heart rate variability (HRV) as a primary outcome measure, and on maximum oxygen consumption (VO2max), body composition, and lower limb muscle strength as secondary outcome measures, in sedentary young women. Methods Thirty-six participants were recruited in this study. The LVHIIT group (n= 17) performed one 4-min bout of treadmill …

Appropriate dietary habits and healthy nutrition play a part in weight control. Set positive principles make precondition for satisfactory state of the body and its composition. Body mass index (BMI) is most commonly used to assess optimal body mass in relation to health risks. However, BMI does not enable the representation of individual body components and may lead to misdiagnosis in one person. The aim of our study was to evaluate dietary habits and selected body composition parameters based on BMI. Moreover, we evaluated these …

In the current study individuals with a history of drug abuse (users of heroin, cocaine, or amphetamine) displayed a 13–100% increase in body weight (self-reported) and exhibited a trend toward insulin resistance. Therefore, we investigated the effects of long-term altitude hiking on insulin sensitivity in this special population. Nine males recovering from drug addiction (ex-addicts)(age 28.7±1.3 years) and 17 control subjects (age 29±1.1 years) voluntarily participated in a 25-day hiking activity (altitude 2200–3800 M). On the 25th day of …

Problem Statement: Breakfast is considered the most influential meal and a key component of weight control, but it is believed that many college students tend to skip this meal. Purpose: To assess relationships between breakfast habits, body composition, and physical activity in undergraduate college students at a rural private university. Approach: Undergraduate college students (n= 197) completed a survey about breakfast and physical activity habits and completed body composition and body mass index (BMI) assessments. A …

Background: This study aimed to investigate the effects of self-paced cycling at an active workstation on executive functions and cortical activity. Methods: In a crossover study design, 37 young adults (45.9% females) were randomly assigned to the following two task conditions:(1) performing cognitive tests during sitting,(2) performing cognitive tests while cycling at an active workstation. Executive functions were assessed by the Stroop color and word test and the task-switching paradigm. Cortical activity was monitored using a multi …

The purpose of this study was to investigate the effects of 16 weeks of spinning and bicycling exercises on body composition, physical fitness and blood variables in female adolescents. Subjects participated in this study were 24 female middle school students (12 spinning cycles, 12 general bicycles) attending to Seoul Yeoksam middle school. Each group was trained for 16 weeks, 3 times a week, and 1 hr per day after school. Body composition, physical fitness (1,200 running, sit-ups, back strength, sit and reach, side-steps) and blood …

Introduction Progranulin (PGRN) is secreted by adipose tissue and has been linked to obesity, insulin resistance and type 2 diabetes mellitus. There is evidence that a high fat diet increases PGRN expression in rodent adipose tissue. In humans, the relationship between diet composition and concentration of PGRN is still unknown. Objective To investigate the association between dietary intake and serum PGRN levels. Methods This is an exploratory cross-sectional study including 85 subjects. Demographic, clinical, laboratory and …

This study attempted to investigate whether nutrient and food intake were related with mild cognitive impairment (MCI) in adults and elderly over 50 years of age in Korea. Questionnaires and anthropometric measurements were conducted on general aspects of the research, and food frequency questionnaires (FFQs) were conducted to determine nutritional status. The relative theta power (RTP) through electroencephalography (EEG) measurements, neurocognitive function test (NFT; CNS Vital Signs), and cognitive function …
