The Peroxisome Proliferator- Activated Receptor (PPARA) gene is associated with the synthesis of Peroxisome Proliferator- Activated Receptor Alpha (PPARA), a protein associated with the activation of other genes and also in regulation of fatty acid oxidation during exercise. A lack of energy in the cells activate this gene like during endurance exercises or when fasting. Variants of the gene are shown to be associated with endurance, power, aerobic capacity and cardio fitness (heart rate)
PPARA level is higher in tissues which catabolize fatty acids like skeletal and cardiac muscle and the liver while it is lower in other tissues like the pancreas
In a study conducted on athletes, people with G variant were associated with endurance. A similar study conducted on soccer players showed that people with the G variant were highly represented. People with the G variant were found to have higher amount of slow twitch fibers.
People with the C variant of the gene had better hand grip strength, thereby, better at power based activities than people with the G variant.
People with the G variant were associated with higher values of oxygen pulse.
[Advantage] More likely to have better endurance
[Advantage] More likely to have more slow twitch fibers
[Advantage] More likely to have better aerobic capacity
[Advantage] More likely to have higher oxygen pulse
|GC||Moderate power and endurance|
|CC||[Advantage] More likely to have better power
[Advantage] More likely to have more fast twitch fibers
[Limitation] More likely to have lower aerobic capacity
[Limitation] More likely to have lower oxygen pulse
