Define and Discuss the size principle and how it relates to neural firing rate and recruitment of skeletal muscle.
This will be a discussion post discussing the size principle and neuromuscular system within the field of exercise science. You must support your response with at least two new peer-reviewed articles, but can also cite any of the provided resources. For this particular assignment, using Kenney W. L., Wilmore, J., Costill, D. Physiology of Sport and Exercise (7th ed.). Human Kinetics, Champaign, IL. 2019 Ch. 1 & 3 “Structure and Function of Exercising Muscle” & “Neural Control of Exercising Muscle ”, respond to the following topic:
Define and Discuss the size principle and how it relates to neural firing rate and recruitment of skeletal muscle. Use a practical applied example as part of your response.
Discussions require a response to specific questions that results in collaborative conversations and construction of knowledge that builds and expands learning within the course. You must support your Discussion postings and responses with references, unless you are asked to provide personal opinion or personal reflection for a specific question. Unless noted otherwise, your initial discussion postings should be approximately 500 words in length, substantive and scholarly in nature. I have attached links to relevant videos explaining these topics and other recommended resources to elaborate on the assignment expectations.
