introduction: creating a calm and stress-free environment affects education significantly. the effects of the emergency department overcrowding (edo) on the training of emergency medicine residents (emr) is a highly debated subject. therefore, this study aimed to evaluate the effect of edo on efficiency of emr’s education. methods: in this cross-sectional study, the effects of overcrowding on e...

introduction: the prevalence of chronic diseases increases with age. increased production of reactive oxygen species (ros) involves in the pathogenesis of cardiovascular diseases such as coronary atherosclerosis, hypertension, diabetic vascular complications, and heart failure. the present study aimed to explore the effects of resistance training on plasma hydrogen peroxide level of ageing wome...

The purpose of this study was to compare the effects of combined strength and plyometric training with strength training alone on power-related measurements in professional soccer players. Subjects in the intervention team were randomly divided into 2 groups. Group ST (n = 6) performed heavy strength training twice a week for 7 weeks in addition to 6 to 8 soccer sessions a week. Group ST+P (n =...

BACKGROUND The benefits of community-based health programs are widely recognized. However, research examining factors related to community leaders' characteristics and roles in implementation is limited. METHODS The purpose of this cross-sectional study was to use a social ecological framework of variables to explore and describe the relationships between socioeconomic, personal/behavioral, p...

The aim of the present study was to examine the effect of in-season strength maintenance training frequency on strength, jump height, and 40-m sprint performance in professional soccer players. The players performed the same strength training program twice a week during a 10-week preparatory period. In-season, one group of players performed 1 strength maintenance training session per week (grou...

Aminimumweekly frequency of concurrent training (1 session per week of strength training and 1 session per week of cycle endurance training) may be an efficient stimulus in elderly in early phases of training; For concurrent-training protocols in which both strength and endurance training are performed on the same day, the strength gains may be optimized with strength training before endurance ...

The use of strength training designed to increase underlying strength and power qualities in elite athletes in an attempt to improve athletic performance is commonplace. Although the extent to which strength and power are important to sports performance may vary depending on the activity, the associations between these qualities and performance have been well documented in the literature. The p...
