| ABSTRACT | |||
| Obesity and its metabolic consequences are major risk factors
for cardiovascular morbidity and mortality. However, lifestyle interventions,
including exercise training and dietary components may decrease cardiovascular
risk. Hence, this study was conducted to assess the effects of ginger supplementation
and progressive resistance training on some cardiovascular risk factors
in obese men. In a randomized double-blind design, 32 obese Iranian men
(BMI > 30) were assigned in to one of four groups: Placebo (PL, n = 8);
ginger group (GI, n = 8) that consumed 1 gr ginger/d for 10 wk; resistance
training plus placebo (RTPL, n = 8); and 1gr ginger plus resistance exercise
(RTGI, n = 8). Progressive resistance training was performed three days
per week for 10 weeks and included eight exercises. At baseline and after
10 weeks, body composition and anthropometric indices were measured. To
identify other risk factors, venous blood samples were obtained before and
48-72 hours after the last training session for measurement of blood lipids
(LDL-C, HDL-C, TG), systemic inflammation (CRP), and insulin resistance
(HOMA-IR). After 10 weeks both RTGI and RTPL groups showed significant decreases
in waist circumference (WC), waist-to-hip ratio (WHR), body fat percent,
body fat mass, total cholesterol, and insulin resistance (p < 0.05) and
a significant increase in fat free mass (FFM) (p < 0.05), while it remained
unchanged in PL and GI. Further, significant decreases in the mean values
of CRP were observed in all groups except PL (p < 0.05). Our results
reveal that resistance training is an effective therapeutic strategy to
reduce cardiovascular risk in obese Iranian men. Further, ginger supplementation
alone or in combination with resistance training, also reduces chronic inflammation.
However more research on the efficacy of this supplement to reduce cardiovascular
risk in humans is required. Key words: Cardiovascular risk factors, resistance training, ginger supplementation. |
