Background: Angiogenesis is a physiological process leading to capillary density enhancement and better blood distribution in skeletal muscles, which triggers in response to physical training. The present study aimed to investigate the changes in physiological factors involved in angiogenesis in response to circuit or traditional resistance training.
Methods: Thirty-six healthy sedentary students who were studying at Shahid Rajaee Teacher Training University of Tehran (age: 22.1±2.3 years; height: 172.7±5.1 cm) volunteered to participate in the study (from October 2021 to February 2022). Following a pre-test to evaluate one repetition maximum (1RM) of selected movements (Leg Press, Leg Curl, Leg Extension, Bench Pull, Seated Row, Biceps Curl), subjects randomly divided into Circuit Resistance training (CRT) (training protocol included 4 circles/3 times a week/8 weeks circuit performance/50-55% 1 Repetition Maximum (1RM), n=12), Traditional resistance training (RT) (training protocol included 8 repetition/3 set/3 time per week/8 weeks of same movements with 75% 1RM followed by 2 minutes break to rest between the sets; n=12) and the control group without any regular training (n=12). We assessed the level of Vascular Endothelial Growth Factor (VEGF), plasma level of growth hormone (GH), and Basic Fibroblast Growth Factor (BFGF) to the mentioned training methods. Data were evaluated by utilizing SPSS version 14.

Results: Present findings showed that CRT and RT protocols resulted in significant increases in post-test compared to pre-test in VEGF (P=0.00), GH (P=0.04), and BFGF (P=0.00). In addition, the magnitude of changes in VEGF and GH were significantly greater than the magnitude of changes in control group in post-test (P=0.03, and 0.001, respectively). Furthermore, there was a strong correlation between absolute values of GH and VEGF (r=0.74 and r=0.71) following CRT (P=0.01) and RT (P=0.02).
Conclusion: This study demonstrated that CRT and RT might enhance angiogenesis through an increase in VEGF, bFGF and GH, leading to better blood distribution in muscles. |
