SUMMARY: This study looked at “normal weight female physique athletes” and how weight loss (specifically loss of visceral fat) decreased inflammation and increased enzymes that were beneficial for cardiovascular health. Results showed that weight loss upregulated genes that contributed to anti-inflammation and removal of fats from arteries; however, when participants gained the weight back, genes that could cause cardiovascular harm were upregulated. Researchers concluded that exercising and limiting calories improves cardiovascular health.
LESSON COMMENTS: Science topics that this paper applies to includes: contents of blood, lipogenesis, function of the liver, and gene regulation. Could the results of this paper address/support some of the common viewpoints we have about exercise and health?
