Genetics May Impact Exercise Outcomes

You can’t blame your parents if you prefer a sedentary lifestyle. However, research has shown a link between physical activity and genetics. Physically active adults express a combination of social, environmental, and psychological factors, which inspire the desire to remain physically fit. Biology also plays a role, and genetic makeup may affect a person’s sedentary or active behaviors. For adults who come from health-conscious families, there is significant motivation to prepare to exercise, purchase activewear nz, and keep track of physical activity. According to studies, as much as 60 percent of an individual’s inclination to work out or not may have been inherited.


Genetics data for physical activity is limited. However, a study measuring genome-wide association was published in 2009. According to this study, there is an association between an individual’s interest traits, which was found using statistical methods. Researchers also noted an association between physical activity and genetics.

A HERITAGE Family Study of more than 740 sedentary subjects, followed a controlled training program over a 20 week period and revealed that genetics played a significant role in participants’ responsiveness to the exercise program. By monitoring heart rate, blood pressure, and cholesterol, researchers determined that responses to the training program revealed similar variation patterns, related to familial influences.

Researchers must measure the impact of endurance training from a hereditary perspective, because in this study there were distinct differences in training adaption, which left a number of questions about the role genetics plays in exercising. Is genetic diversity a variable in biological responses to physical activity? Are genes an indicator of an individual’s ability to positively or negatively respond to rigorous exercise? Responses to regular exercise during the course of this study directly corresponded with familial aggregation, as members of family groups exhibited similar responses. Exercise significantly increases enzyme levels and the study showed, between 78 individuals and 19 families, a lesser variance in enzyme levels within family groups.

Genetic predispositions may attribute to a person’s exercise tolerance or capacity levels. Gene defects may significantly limit the ability to perform certain physical activities and contribute to metabolic energy levels. Molecular makeup may also impact both cardio endurance and ability, because some genes are aligned with a lower exercise capacity. However, regardless of genetics, regular exercise has proven effective in improving and maintaining individual health.
