Oxidative balance score reflects vascular endothelial function of Chinese community dwellers.

The oxidative balance score (OBS) is a composite estimate of the overall pro- and antioxidant risk status in an individual. The aim of this study is to explore the association between the OBS and vascular endothelial function in Chinese community dwellers. In total, 339 community dwelling adults (aged 20-75 years) were recruited in this study.

Effects of Time to Start Training After Acute Patellar Tendon Enthesis Injuries on Healing of the Injury in a Rabbit Model.

Background: A patellar tendon injury is a common injury in sports. The optimal time to start training after an acute, proximal patellar enthesis injury is still unclear.

Hypothesis: The time to start training after an acute, proximal patellar enthesis injury significantly affects healing of the patellar tendon 4 weeks after the injury.

A cross-sectional study of cardiorespiratory fitness and gallbladder disease.

Purpose: To determine the association of different levels of cardiorespiratory fitness (CRF), an objective indicator of habitual physical activity, with gallbladder disease.

Methods: In the Aerobics Center Longitudinal Study (ACLS) database, 41,528 men and 13,206 women aged 20-90 years, with body mass index of 18.5 or more and without history of cardiovascular disease and cancer, received a preventive examination at the Cooper Clinic in Dallas, Texas, between 1970 and 2003.

VEGF and BFGF Expression and Histological Characteristics of the Bone-Tendon Junction during Acute Injury Healing.

Bone-tendon junction (BTJ) injuries are common and may be caused by acute trauma and delayed healing during exercise or work. To understand the nature of the healing process of BTJ injuries would help to prevent injuries and improve treatment. Thirty-three mature female rabbit hindlimbs were assigned to normal control (CON, n = 7) and injury groups (n = 26).

Effect of skill level on cardiorespiratory and metabolic responses during Tai Chi training.

Nowadays, Tai chi chuan (TCC) is practiced by millions worldwide with a range of skill levels. However, the effect of skill level on physiological response to TCC performance has yet to be clarified. In this study, physiological parameters during practicing simplified 24-form TCC were investigated and compared in 10 young high-level (HL) male TCC athletes and 10 ordinary-level (OL) male TCC practitioners with similar age and body size.

Analyses of body composition charts among younger and older Chinese children and adolescents aged 5 to 18 years.

Background: Childhood obesity has become a major public health problem in China. The objective of this study was to examine the effect of age and sex on the relationship between fat-free mass (FFM) and fat mass (FM), fat-free mass index (FFMI) and fat mass index (FMI) in Chinese children using body composition chart analysis, and to compare the changing pattern with Caucasian and Japanese counterparts.

Methods: A total of 1458 children (790 boys and 668 girls) between 5 and 18 years of age were studied to determine a body composition by bioelectrical impedance analysis.

The effects of an early return to training on the bone-tendon junction post-acute micro-injury healing.

Bone-tendon junction (BTJ) overuse injuries are common athletic and occupational problems. BTJ injuries may sometimes be caused by resuming training too early after injury. To study the effects of post-injury resuming training within 48 hours on the acute injury healing process, as it is often the case for athletes.
