The role of GTOs in monitoring muscle tension 

Following on from our last blog on Muscle Spindles, today’s fitness blog maintains the same theme. It breaks down further complexities of the muscular system, spotlighting the pivotal role of Golgi Tendon Organs (GTOs). This in-depth knowledge is essential for anyone involved in fitness or looking to embark on online personal training courses.

Golgi Tendon Organs, a vital part of our muscle physiology, are located where a tendon connects to a skeletal muscle – often called the Musculotendinous Unit (MTU). These specialised proprioceptive sensory organs communicate with the central nervous system via their afferent nerve, playing an integral part in any advanced fitness course online.

Muscle Tension

The primary job of GTOs is to act as tension detectives in our muscles, continuously gauging the force exerted by a muscle during both contraction and stretch. So, in contrast to Muscle Spindles, which measure the rate of which muscle length changes, GTO’s measure the amount of tension being applied through the muscle.

Additionally, GTOs can inhibit muscular contractions when excessive force is detected, a safety mechanism designed to prevent potential damage to the tendons and muscles – an important lesson for any personal trainer and a key topic covered in our online personal training course.

While some discussions revolve around the complete inhibitory capacity of GTOs, it’s more widely accepted that GTOs collaborate with muscle spindles. Together, they work towards preventing a muscle from over-stretching or being overloaded.

Application to Exercise Prescription

Understanding the role of GTOs can guide the design of a progressive weight training programme. Gradually increasing the intensity ensures that the GTOs adapt to the increasing resistance, enabling muscles to develop with minimum discomfort and maximum adherence. This strategy is an essential component of progressive overload and the development of clients central nervous system, which is essential to understand for any personal trainer or online coach.

GTOs also play an important role in Proprioceptive Neuromuscular Facilitation (PNF) stretching, a method often included in a personalised training programme to ensure. When an individual performs a specific stretch, GTOs, working with the muscle spindles, monitor the tension build-up in the muscle. As the muscle relaxes, GTOs facilitate further relaxation, allowing the muscle to lengthen. This approach, when repeated, can result in a greater range of movement.

Summary

Those interested in delving deeper into muscle physiology and its application in fitness training may consider enrolling in online personal training courses. With the availability of advanced learner loans, getting a Level 3 Diploma in Personal Training is now more accessible than ever.
