the aim of this study was to investigate the effect of 10 weeks of resistance training on serum levels of heat shock protein 70 (hsp70) and insulin resistance in type 2 diabetic women. 20 women with type 2 diabetes were selected by purposive sampling method and randomly divided into experimental group (n = 10, mean age 47.13±6.27 year, bmi 28.45±3.32 kg/m²) and control group (n = 10, mean age 5...

Importance More research is required to clarify the association between physical activity and health in "weekend warriors" who perform all their exercise in 1 or 2 sessions per week. Objective To investigate associations between the weekend warrior and other physical activity patterns and the risks for all-cause, cardiovascular disease (CVD), and cancer mortality. Design, Setting, and Parti...
