We investigated the associations between cardiovascular function and both body mass index and physical fitness in Korean men. The subjects were 2,013 men, aged 20 to 83 years, who visited a health promotion center for a comprehensive medical and fitness test during 2006-2009. The WHO's Asia-Pacific Standard Report definition of BMI was used in this study. Fitness assessment of cardiorespiratory...

[Purpose] The aim of this study was to examine the relationships among vitamin D levels, balance, falls, muscular strength, and quality of life in patients with postmenopausal osteoporosis. [Subjects and Methods] Forty-six patients diagnosed with postmenopausal osteoporosis and forty-six healthy controls were included in the study. Bone mineral density was determined by DEXA, and functional bal...

Aging is associated with sarcopenia, which is a loss of skeletal muscle mass and function. Coenzyme Q10 (CoQ10) is involved in several important functions that are related to bioenergetics and protection against oxidative damage; however, the role of CoQ10 as a determinant of muscular strength is not well documented. The aim of the present study was to evaluate the determinants of muscular stre...

Research has indicated that multiple sets are superior to single sets for maximal strength development. However, whether maximal strength gains are achieved may depend on the ability to sustain a consistent number of repetitions over consecutive sets. A key factor that determines the ability to sustain repetitions is the length of rest interval between sets. The length of the rest interval is c...

BACKGROUND Although muscular dystrophy causes muscle weakness and muscle loss, the role of exercise in the management of this disease remains controversial. OBJECTIVE The purpose of this systematic review is to evaluate the role of exercise interventions on muscle strength in patients with muscular dystrophy. METHODS We performed systematic electronic searches in Medline, Embase, Web of Sci...

OBJECTIVE An assessment protocol was applied to quantify and describe muscular strength and motor abilities of 32 patients with Duchenne muscular dystrophy (DMD), aged between 5 and 12 years on steroid therapy. METHOD Assessments were made monthly for the first six months and with intervals of two months thereafter until the 14-month end point. The tests employed included: the Medical Researc...

[Purpose] The purpose of the present study was to clarify the effect of dyspnea induced by breath-holding on maximum muscular strength of patients with COPD. [Subjects] This study recruited 14 COPD subjects via public posting. [Methods] Dyspnea was assessed by the modified Borg scale. The subject asked to stop breathing at end-expiration and to hold their breath with a nose clip for as long as ...

the purpose of the present study was to examine differences in lifestyle factors such as physical activity among homosexual (gay or lesbian), bisexual, and heterosexual korean adolescents.the sample consisted of 74,186 adolescents from grades 7-12 (ages 12-18) who participated in the 8(th) annual korea youth risk behavior web-based survey in 2012. of this sample, only 11,829 provided enough inf...

Low muscle strength is independently associated with a poorer metabolic profile during adolescence (1) and with disease and all-cause mortality in adulthood (2). Muscular fitness, which includes maximal isometric strength, explosive strength and muscular endurance is also positively associated with skeletal health (1). Tomkinson (3) reported steady increases in measures of explosive lower body ...
