The intensity was determined using...

Abstract To examine the effect of high-intensity interval training (HIIT) with different work-to-rest ratios on athletic performance in athletes. Forty-seven male Taekwondo athletes (aged 15–18 yrs) were randomly assigned into 3 HIIT groups and a control group. Each group performed 6 8 bouts HIIT: 1) 1:2 (30:60 s), 2) 1:4 (30:120 3) 1:8 (30:240 s) while only program. All completed 10 sessions over 4 weeks. Athletic tests including VO2max test, Wingate anaerobic vertical jump, agility T-test...

The purpose of this study was to examine the associations vitamin D status with athletic performance and blood-borne markers in adolescent athletes. This cross-sectional included forty-seven Taekwondo athletes, aged 15-18 years old. Athletic assessed using maximal oxygen consumption (VO2max), Wingate anaerobic power test, vertical jump, agility T-test, lower limb muscle strength, fatigue resistance. Blood samples were collected assess serum 25-hydroxyvitamin [25(OH)D], free-testosterone,...

Among US firefighters, sudden cardiac arrest and psychological stress (i.e., PTSD) are the leading cause of on-duty death. Metabolic syndrome (MetSyn) may influence both cardiometabolic cognitive health. Here, we examined differences in disease risk factors, function, physical fitness firefighters with vs. without MetSyn.One hundred fourteen male aged 20 to 60 years, participated study. MetSyn non-MetSyn were divided by AHA/NHLBI criteria. Of them, performed a paired-match analysis respect...

This study examined the effects of high-impact weight-bearing exercise on bone mineral density (BMD) and metabolic markers in middle-aged premenopausal women. Forty women were initially enrolled, but thirty-one participants (40.34 ± 3.69 years) completed study. The subjects randomly divided into two groups including group (HWE, n = 14) control (CON, 17). HWE participated for 50 min a day, three days per week four months, while CON maintained their regular lifestyle. program included 10...

Sarcopenia, an age-related disease, is one of the important health problems in elderly and prevalence sarcopenia rapidly increased among Korean population. This study examined muscle quality growth factors women to identify potential diagnostic tool for sarcopenia. One hundred thirty-six women, aged over 65 years old, initially enrolled, but only 59 participants who met criteria (sarcopenic group, n = 27; non-sarcopenic 32) completed study. Muscle assessment included thigh cross-sectional...

Abstract Purpose Physical activity (PA) is a modifiable factor in preventing/treating cardiometabolic disease. However, no studies have yet compared specific moderate-to-vigorous PA (MVPA) domains with the risk of metabolic syndrome (MetS) detail. Here, present study was conducted to examine impact different MVPA (leisure-time (LTPA) vs. occupational (OPA) total MVPA) on MetS Korean adults. Materials and methods: Data from 2014 2021 Korea National Health Nutrition Examination Survey were...
