Can your fitness level really be determined by DNA?

Spitting into vials in the hopes of discovering more about their genes is a common practice among millions of people worldwide; however, their search goes beyond simply learning about their lineage as they have curiosity about how their DNA might impact their diet, risk of injury, level of fitness, and overall health.

According to a Grand View Research market analysis report, the worldwide market for direct-to-consumer genetic testing is expected to grow rapidly over the next several years, leaping from $1.9 billion in 2023 to $8.8 billion by 2030. 

With 60.5% of the market, North America leads the way, but the data indicates that over the next six years, Europe will increase at the highest rate.

According to a study analysis, roughly 20 companies were offering direct-to-consumer genetic tests in 2013 that targeted sports performance and injury risk. By 2019, that number had increased to about 70. 

Furthermore, a 2020 study that was published in the Indian Journal of Orthopaedics revealed that Australia's National Rugby League players use DNA testing to customise their workouts for sprinting or explosive powerlifting, while China and Uzbekistan use genetic testing in their Olympic talent identification programmes, according to CNN.

However, there are a plethora of other variables that influence athletic ability and achievement, including nutrition, sleep patterns, motivation, training regimens, socioeconomic status, and even experiences during pregnancy.
