Explain The Sliding Filament Theory

Unit one

The sliding filament theory:

Before this unit I knew nothing about the sliding filament theory. After learning about the sliding filament theory, I discovered that, it is the contraction of a muscle. It slides the thin actin filament over the thick myosin filaments causing the muscle to shorten and create movement. When I researched more about the sliding filament theory I learned that each muscle fibre is made up by myofibrils, that consist of smaller structures called actin and myosin filaments. These filaments slide in and out between each other. The sliding filament theory is organized in steps. Step one is the process begins with a nervous impulse that arrives at the neuromuscular junction, causing a release of a chemical called

I also knew that is was important to learn activities/ sports the right way to begin with so that bad habits in sport are not developed. While learning about Motor development I discovered that it is a continuous process of sequential changes, where movements become increasingly organized and specialized. Influenced by growth, age, heredity, activity, family and culture. I learned the ages which certain movements occur in Ages 0 to 1, Reflective movement which includes grasping, sucking, Spontaneous movement which includes banging, kicking and Rudimentary movement which includes rolling, sitting, standing and reaching. From Ages 1- 10 Fundamental movements occur, which includes, walking, twisting, running, catching, leaping and drawing. From the ages Age 10-12 in girls and 11- 13 in boys Specialized movements occur which is, increasing sport- specific and can be used in various competitive or recreational movement (skiing, dancing,

It affects a child’s ability to do a wide range of everyday physical tasks, including, jumping, speaking clearly and gripping a pencil. This condition affects gross and fine motor skills. Different kinds of dyspraxia are, ideomotor which makes it hard to complete motor tasks such as, combing hair, or waving goodbye, ideational which makes it more difficult to perform a sequence of movements, like brushing teeth or making a bed and constructional have a hard time coping geometric drawings or using building blocks. Currently to help kids with this disorder they can go to occupational therapy which helps the child develop everyday skills needed to thrive in and out of school. This includes thins such as learning to use a knife or fork. They can also go to perceptual motor training which improves the child’s language, visual movement, hearing and listening skills. This involves giving the child tasks that are challenging, they are also given exercises that will help them better learn how to integrate language information. For parents that have a child with dyspraxia they can, learn as much as possible about dyspraxia, encourage physical activity, do jigsaw puzzles, this will help improve fine motor skills, toss a bean bag to develop hand-eye coordination, get pencil grips, to make it easier for the child to write, get some putty or playdough, to help strengthen the hand muscles and
