Artificial intelligence (AI) is gradually influencing every aspect of everyday life, including education. AI can also provide special support to learners through academic sustainability or discontinuation predictions. While AI research remains in its early stages, we must examine how it evolves and exerts its potential over time. By utilizing AI in physical education (PE), we can increase its potential use in sports applications, and enact changes upon the nature of PE, its visualization, and re

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. Criterion-related validity of the K-GPAQ was examined with 199 participants using accelerometers. Cohen's kappa and Spearman'

Studies have reported conflicting results on the association between body mass index (BMI) and prognosis of colorectal cancer. Therefore, we have conducted a meta-analysis of prospective studies, which examined the association of pre- and post-diagnostic BMI with colorectal cancer-specific mortality and all-cause mortality in patients with colorectal cancer. We searched Medline and EMBASE database published between 1970 and September 2014. A total of 508 articles were identified, of which 16 pro

Physical activity may decrease the risk of dementia; however, conflicting findings exist. The purpose of the current meta-analysis was to investigate the relationship between physical activity and dementia risk based on physical activity type, amount, and intensity, and to propose an effective minimal physical activity amount for older adults. Forty-four studies were selected for the meta-analysis. Participation in high (a total of >2 hours of activity over the course of three sessions per week)

This meta-analysis suggests diabetes may result in a worse prognosis for men with prostate cancer. Considering heterogeneity between studies, additional studies should be conducted to confirm these findings, and to allow generalization regarding the influence that each type of diabetes has on prostate cancer mortality.

Empowering BC patients to implement these exercise interventions could not only improve their health and QL, but also reduce fatigue, depression, and anxiety during adjuvant therapy.

Participating in PA is an essential factor in breast cancer care that extends throughout the life span of cancer survivors. Higher levels of PA than current PA guidelines should be recommended to cancer patients.

(1) Background: Exercise interventions for overweight and obese individuals help reduce accumulated visceral fat, which is an indicator of cardiometabolic risk, but the effectiveness of these interventions is controversial. The purpose of this meta-analysis was to investigate the effectiveness of exercise interventions in overweight and obese individuals in order to reduce weight, body mass index (BMI), and accumulated visceral fat, and increase lean body mass. (2) Methods: Databases were used t

(1) <i>Background</i>: The purpose of this meta-analysis was to investigate the effects of combined exercise and low carbohydrate ketogenic diet interventions (CELCKD) for overweight and obese individuals. (2) <i>Methods</i>: Relevant studies were searched by using the MEDLINE and EMBASE databases up to October 2020. Study Inclusion and Exclusion Criteria: Inclusion criteria were reporting effects of the CELCKD for overweight and obese individuals from randomized controlled trials. Studies that

The purpose of this study was to determine favorable physical activities, by intensity, type, and frequency that would serve to minimize the prevalence of metabolic syndrome. A total of 24,178 individuals participated in the Korean National Health and Nutrition Examination Survey that investigated the risk factors for metabolic syndrome and physical activity including the physical activity type (vigorous and moderate activity, walking, strength, and flexibility) and the frequency (numbers of day

Aerobic exercise may be beneficial to reduce body fat, fasting insulin, and inflammatory markers, and increased physical fitness for overweight and obesity in childhood and adolescence, but resistance exercise may be added, which can help avoid muscle loss in children and adolescents with overweight and obesity.

Several controversial studies linking handgrip strength and health have suggested that low handgrip strength in older adults may be related to health problems and have investigated whether there is a minimum handgrip strength level associated with reduced mortality. Thus, by meta-analysis, the authors identified an association between handgrip strength in older adults and disease-specific mortality and all-cause mortality. Thirty studies with a total of 194,767 older adult participants were incl

(1) Background: The purpose of this meta-analysis is to investigate the effects of exercise intervention for older adults with mild cognitive impairment (MCI). (2) Methods: Databases including PubMed, Medline, and Cochrane were used to search for studies that reported effects of exercise for older adults with MCI and randomized controlled trials up to July 2020. Exercise interventions of all selected studies were summarized, and effect sizes of exercise interventions were calculated. (3) Results
