And Now for some news ….
Exercise and DNA
A study in the journal Epigenetics looked at the connection between Exercise and our DNA.
Regular endurance exercise training induces beneficial functional and health effects in human skeletal muscle. The putative contribution to the training response of the epigenome as a mediator between genes and environment has not been clarified.
The authors of the study investigated the contribution of DNA methylation and associated transcriptomic changes in a well-controlled human intervention study.
Training effects were mirrored by significant alterations in DNA methylation and gene expression in regions with a homogeneous muscle energetics and remodeling ontology.
Moreover, a signature of DNA methylation and gene expression separated the samples based on training and gender. Differential DNA methylation was predominantly observed in enhancers, gene bodies and intergenic regions and less in CpG islands or promoters.
The study concluded that highly consistent and associated modifications in methylation and expression, concordant with observed health-enhancing phenotypic adaptations, are induced by a physiological stimulus.

Weight Loss and Exercising in Cold Temperatures
A recent study about to be published in the journal Medicine & Science in Sports & Exercise researched the effects of exercising in cold temperatures may have on weight loss.
Exercise in cold water has been shown to simulate postexercise energy intake (EI) in normal-weight individuals. However, the effect of cold exercise on EI in overweight individuals has yet to be examined.
The present study investigated the effect of brisk walking in a cold (8°C) and neutral (20°C) environment on postexercise EI and appetite hormone responses.
The study concluded that these findings show that in overweight individuals, exercise in the cold stimulates postexercise energy intake to a greater extent than exercise in a neutral environment.
Remember to discuss all Exercise and Nutrition related questions with your Qualified Health Care Provider.
