Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Vitamin K includes a group of structurally related compounds named phylloquinone (vitamin K1) and menaquinones (vitamin K2s) of which MK-4 and MK-7 are the most important. Vitamin K is an essential cofactor for gamma carboxylation, required for the effective function of a range of proteins and has been linked to chronic disease and inflammation. Muscle cell studies suggest that vitamin K2 increases expression of myogenic transcription factors such as MyoD and promotes muscle cell proliferation. There are 20 described vitamin K dependent proteins (VKDPs). It is also known that vitamin K2 inhibits the activation of NFkB independently of gamma-carboxylation. This prevents nuclear entry of NFkB and therefore, consequently, vitamin K2 inhibits NFkB to interact with its nuclear receptors. In addition, Vitamin K2 can function as an electron carrier in mitochondria, and therefore play an inhibitory role on oxidative stress and release of ROS. There is, therefore, a strong rationale for investigating the effects of vitamin K2 during ankle immobilisation. The aim of the study is to investigate the effects of vitamin K2 on skeletal muscles after ankle injury and in the recovery process.
