Development of a New Submaximal Walk Test to Predict Maximal Oxygen Consumption in Healthy Adults.

The aim of the study was to develop a simple submaximal walk test protocol and equation using heart rate (HR) response variables to predict maximal oxygen consumption (VOmax). A total of 60 healthy adults were recruited to test the validity of 3 min walk tests (3MWT). VOmax and HR responses during the 3MWTs were measured.

Physical activity and quality of life of patients with inflammatory bowel disease.

A new anthropometric index to predict percent body fat in young adults.

Objective: To propose a new anthropometric index that can be employed to better predict percent body fat (PBF) among young adults and to compare with current anthropometric indices.

Design: Cross-sectional.

Setting: All measurements were taken in a controlled laboratory setting in Seoul (South Korea), between 1 December 2015 and 30 June 2016.

Validation of Submaximal Step Tests and the 6-Min Walk Test for Predicting Maximal Oxygen Consumption in Young and Healthy Participants.

: This study aimed to test the validity of three different submaximal tests (i.e., 3-min step test with 20.

Development of the Korean Global Physical Activity Questionnaire: reliability and validity study.

The goal of this study was to develop a Korean version of the Global Physical Activity Questionnaire (K-GPAQ) and to examine its reliability and validity. The English version of the GPAQ was translated to the Korean language (K-GPAQ) via forward-backward translation. Reliability of the K-GPAQ was evaluated using a one-week interval test-retest method with 115 individuals.

Cardiopulmonary fitness but not muscular fitness associated with visceral adipose tissue mass.

Purpose: The purpose of this study is to identify the association between physical fitness (cardiopulmonary and musculoskeletal) and the distribution of abdominal fat in overweight and obese adults.

Methods: Of the total 102 overweight and obese participants, 99 participants completed all measurements. Cardiopulmonary fitness was assessed by maximal oxygen consumption test and muscular fitness was assessed using 10 repetition max.

Development process of an evidence-based exercise program for post-operative colorectal cancer patients.

Purpose: Exercise is generally accepted to be beneficial for colorectal cancer patients; however, very few studies have investigated the effects of exercise on patient care and health outcomes during the immediate post-operative recovery period. Furthermore, very few studies have investigated the safety, feasibility, and efficacy of exercise on post-operative cancer patients. Although intervention programs should be based on solid evidence from clinical trials, the majority of previous studies have not presented the development process of the intervention programs.

Dry Electrode-Based Body Fat Estimation System with Anthropometric Data for Use in a Wearable Device.

The bioelectrical impedance analysis (BIA) method is widely used to predict percent body fat (PBF). However, it requires four to eight electrodes, and it takes a few minutes to accurately obtain the measurement results. In this study, we propose a faster and more accurate method that utilizes a small dry electrode-based wearable device, which predicts whole-body impedance using only upper-body impedance values.

Effects of alternate day calorie restriction and exercise on cardio-metabolic risk factors in overweight and obese adults: an exploratory randomized controlled study.

Background: It has been recognized that alternate day calorie restriction (ADCR) or exercise has positive effects on cardio-metabolic risk factors. It is unclear whether the combined effect of ADCR and exercise (aerobic + resistance training) influences risk. We investigated effects of an 8-week ADCR and exercise program (aerobic + resistance training) on cardio-metabolic risk factors in overweight and obese adults.

Effect of home-based exercise intervention on fasting insulin and Adipocytokines in colorectal cancer survivors: a randomized controlled trial.

Background And Aims: Elevated circulating insulin is associated with increased risk of recurrence and cancer mortality in early-stage colorectal cancer (CRC). We conducted a randomized controlled trial to determine the effect of a 12-week home-based exercise program on fasting insulin, adipocytokines, and physical function in CRC survivors.

Methods: One hundred and twenty-three stage II-III CRC patients were randomly assigned to either a home-based exercise (n=62) or standard care control group (n=61) for 12weeks.

Results From South Korea's 2016 Report Card on Physical Activity for Children and Youth.

Background: South Korea's 2016 Report Card on Physical Activity for Children and Youth is the first assessment of physical activity according to the indicators set by Active Healthy Kids Global Alliance.

Methods: National surveys were used as preferred sources of data. This was then supported by peer-reviewed papers and government reports identified by a systematic search of the literature written in English or Korean.

The association between resting heart rate and type 2 diabetes and hypertension in Korean adults.

Objective: The purpose of this study was to analyse the association between resting heart rate (RHR) and type 2 diabetes and hypertension in Korean adults.

Methods: A total of 5124 participants, who participated in the exercise programme at the National Health Promotion Center between 2007 and 2010 (male=904, female=4220) were analysed in this study. Anthropometrics, body mass index (BMI), blood pressure (BP) and RHR were measured, and blood samples were collected after fasting for at least 12 hours.

Cardiopulmonary fitness, adiponectin, chemerin associated fasting insulin level in colorectal cancer patients.

Purpose: Since circulating level of insulin is associated with colorectal cancer prognosis, it is important to identify factors contributing to fasting insulin level in colorectal cancer patients. The purpose of the current study is to investigate the association of physical fitness, adiponectin, and chemerin levels with circulating level of insulin in colorectal cancer patients.

Methods: A total of 123 stage II-III colorectal cancer patients who completed standard cancer treatment were recruited.
