چکیده:
Introduction: CrossFit is recognized as one of the fastest growing modes of high-intensity functional training. Exercise training is a useful strategy for controlling blood lipid profile. The effect of CrossFit training on blood lipid profile is not well known. Thus, the aim of this study was to investigate the effect of 12 weeks CrossFit training on blood lipid parameters in overweight men. Material & Methods: Twenty sedentary overweight men (BMI: 28.4 ± 1.4 kg.m-2) participated in this study as the subject. The subject based on their maximum oxygen uptake were divided into control (n=10) or CrossFit (n=10) group randomly. The participants in CrossFit group were performed selected CrossFit training 3 days a week for 12 weeks. Blood samples were collected before and 48h after the intervention. Results: Date indicated that plasma glucose (96.2±7.1 to 78.5±4.3), total cholesterol (TC) (162.6±11.0 to 139.2±6.3), TG (98.2±33.4 to 58.4±13.4) and LDL (95.2±5.4 to 69.7±.7) were decreased and plasma HDL was increased (40.7±3.4 to 62.8±3.3) after CrossFit training in compare to the control group (p Conclusions: Data suggested that CrossFit training is a novel and useful strategy for controlling blood lipid levels and blood glycemia.

Thus, the aim of this study was to investigate the effect of 12 weeks CrossFit training on blood lipid parameters in overweight men.
However the effects of CrossFit training on obesity and blood lipid profile is not well known.
The present study aimed to assess the influence of CrossFit training on blood lipid profile in sedentary and overweight men.
2. Material & Methods Subjects 20 sedentary and overweight men who subscribed in fitness center for training and body weight control have been recruited to participate to the present study.
Plasma glucose and blood lipid profile of the participants in response to 12 weeks CrossFit training (mean±SD) / Glucose (mg/dl) TC (mg/dl) TG (mg/dl) LDL (mg/dl) ‒5.
The decrease of LDL level in the blood after this training period can be explained by the effect of aerobic exercise on fat.
5. Conclusion Data suggested that 12 weeks of CrossFit training is effective in modifying body composition, glucose uptake and blood lipid profile in overweight men.
Effects of CrossFit training on lipid profiles, body composition and physical fitness in overweight men.
Effects of 8 weeks of exercise training program on aerobic fitness, body composition, blood lipid and C-reactive protein in adolescents with obesity.
Effects of the CrossFit exercise data analysis on body composition and blood profiles.
