Physical activity and nutrient intake levels according to grip strength among single-household elderly in Korea: data from 2014 and 2019 Korea National Health and Nutrition Examination Survey (KNHANES).

Purpose: We analyzed the differences in physical activity (PA) levels and nutrient intake based on grip strength among elderly men and women in single-person households (ESH) in Korea.

Methods: Data were obtained from 1,581 ESH individuals (aged ≥65 years) from the Korean National Health and Nutrition Examination Survey (2014-2019). PA levels (occupational and recreational moderate-intensity activities, travel to and from places, walking, and strength training) and nutrient intake (including, total energy, carbohydrates, protein, and fat) were analyzed.

Impact of the ketogenic diet on body fat, muscle mass, and exercise performance: a review.

Purpose: The purpose of this review was to investigate the effects of the ketogenic diet (KD), on body fat, muscle mass, and exercise performance. As the KD is a subject of ongoing debate, we also present the existing evidence regarding its potential benefits in the aforementioned areas of body fat, muscle mass, and exercise performance.

Methods: A literature search was conducted using the keywords "ketogenic diet, low-carbohydrate diet, high-fat diet, body fat, muscle mass, and exercise performance" in PubMed, Web of Science, and Google Scholar.

Changes in physical activity and energy intake according to abdominal obesity in Korean adult men before and after COVID-19: Data from 2019 and 2020 Korea National Health and Nutrition Examination Survey (KNHANES).

Purpose: This study aimed to investigate changes in physical activity and energy intake according to abdominal obesity in Korean adult men before and after COVID-19.

Methods: Using data from the 2019 and 2020 KNHANES, the physical activity level measured by the Global Physical Activity Questionnaire (GPAQ) the physical activity level by GPAQ, number of days of walking and strength training, aerobic exercise, and total energy, protein, fat, carbohydrate, dietary fiber, and sugar intake for a total of 2,799 participants were analyzed.

Results: There were no changes in energy intake during the pandemic.

Influence of high fat and different types of carbohydrate diet on energy metabolism in growing mice.

Methods: To minimize differences in food and energy intake between experimental groups, mice were pair-fed. After 1 week of adaptation, 40 male ICR mice (6 weeks old) were randomly divided into four groups: Sta.

Exposure and Exercise Training in Hypoxic Conditions as a New Obesity Therapeutic Modality: A Mini Review.

Obesity is an important health problem caused by positive energy balance. Generally, low calorie dietary intake combined with regular exercise is the most common modality to lose bodily fat in obese people. Although this is the first modality of choice for obesity treatment, it needs to be applied to obese patients for at least 12 weeks or more and it does not provide consistent results because it is difficult to suppress increased appetite due to exercise.

Non-exercise activity thermogenesis (NEAT): a component of total daily energy expenditure.

Purpose: The purpose of this review is to promote awareness of non-exercise activity thermogenesis (NEAT) as a new strategy to increase energy expenditure, and to manage obesity.

Methods: The content of this review is based on a literature search of PubMed and the Google Scholar search engine, using the search terms obesity, energy expenditure, non-exercise activity thermogenesis (NEAT), and sitting disease.

Results: Daily energy expenditure is of great interest because most obese individuals have no exercise activity-related thermogenesis (EAT); thus their physical activity-related energy expenditure (PEE) is comprised almost entirely of NEAT.

The effect of additional carbohydrate supplements for 7 days after prolonged interval exercise on exercise performance and energy metabolism during submaximal exercise in team-sports athletes.

Purpose: The purpose of our study was to determine the effectiveness of carbohydrate loading by additional carbohydrate supplements for 7 days after prolonged interval exercise on exercise performance and energy metabolism during submaximal exercise in team-sports athletes.

Methods: Twenty male team-sports athletes (14 soccer and 6 rugby players) volunteered to participate in the study and were equally divided into the experimental group (EXP, n=10) performing additional carbohydrate supplementation for 7 days after prolonged interval exercise until blood glucose level reaches 50 mg/dL or less and the control group (CON, n=10). Then, maximal oxygen consumption (VO2max) and minute ventilation (VE), oxygen consumption (VO2), carbon dioxide excretion (VCO2), respiratory exchange ratio (RER), blood glucose level, and blood lactate level were measured in all team-sports players during submaximal exercise corresponding to 70% VO2max before and after intervention.

The effects of exercise and cold exposure on mitochondrial biogenesis in skeletal muscle and white adipose tissue.

Purpose: The purpose of this study was to determine whether exercise or/and cold exposure regulate mitochondria biogenesis-related gene expression in soleus and inguinal adipose tissue of mice.

Methods: Forty ICR 5-week old male mice were divided into four groups: thermoneutrality-untrained (23 ± 1 °C in room temperature, n=10), cold-water immersion (24 ± 1 °C, n=10), exercise in neutral temperature (34 ± 1 °C, n=10), and exercise in cold temperature (24 ± 1 °C, n=10). The mice performed swimming exercise (30 min to 60 min, 5 times) for 8 weeks.

Association of daily physical activity level with health-related factors by gender and age-specific differences among Korean adults based on the sixth (2014-2015) Korea national health and nutrition examination survey.

Purpose: This study examined the effects of daily physical activity level on health-related factors according to gender and identified age-specific differences among Korean adults.

Methods: Using data from the Korea National Health and Nutrition Examination Survey VI (2014-2015), we selected adults aged 19-64 years who participated in both a health examination and health interview survey. The study included 6,457 participants 19-64 years of age (2,611 men, 3,846 women).

Training-induced alterations of skeletal muscle mitochondrial biogenesis proteins in non-insulin-dependent type 2 diabetic men.

This study investigates whether regular physical activity (moderate endurance or resistance training twice a week for 3 months) influences the key regulatory molecules of mitochondrial biogenesis (peroxisome proliferator-activated receptor gamma coactivator-1α (PGC1α), nuclear respiratory factor-1 (NRF1), and mitochondrial transcription factor A (TFAM)) in patients suffering from non-insulin-dependent type 2 diabetes mellitus (T2DM) (n = 16, years = 62 ± 7, body mass index (BMI) = 30 ± 4 kg/m(2)). Seven T2DM men took part in endurance training, and 9 men participated in resistance training. BMI-matched non-diabetic male control subjects (CON) (n = 7, years = 53 ± 6, BMI = 30 ± 4 kg/m(2)) were studied for comparison.

Mini-nutritional assessment predicts functional status and quality of life of patients with hepatocellular carcinoma in Taiwan.

This study aimed to determine the possibility of using the Mini-Nutritional Assessment (MNA) to evaluate the quality of life and functional status in patients with hepatocellular carcinoma (HCC).
