Background Information Muscles in the human body can be classified into three different types- cardiac‚ smooth and skeletal muscles. The skeletal muscles are the muscles that can be controlled voluntarily‚ in things such walking and picking things up. The skeletal muscles are made up of bundles of muscle fibres (which are also known as myofibrils‚ as can be seen below). Each of the muscle fibres contain many sarcomeres‚ which is the most basic form of striated muscle tissue- they consist of two

When trying to reach your muscle growth goals‚ it is important that you have a customized body building workouts that are meant for you. What it means is that you have to take into consideration of your body type and genes‚ and how your metabolism rate is like when determining your workout routine as well as your muscle building diet. Following blindly without being able to improvise and improve will be as effective as compared to body building workouts just for you. One common mistake that most

There are many different things that contribute to the elasticity of muscles‚ but the focus of Aboodarda and colleagues is specifically on myofascia‚ the irregular dense connective tissue that connects and encompasses every muscle and organ in the body‚ as it is the component that is thought to have responsibility for the elasticity of muscle tissues. As a response to injury‚ among other factors‚ myofascia may bond to abutting structures and contract‚ which may cause adhesions. These adhesions may

INTRODUCTION An electronic muscle stimulator is a circuit designed to stimulate nerves of that part of the body by attaching electrodes. It is used to revive frozen muscle that impair movement‚ it aid in building up muscles and it also helps in removing cellulites in the body EMS causes adaption‚ i.e. training of muscles fibers and can be used as a therapeutic tool. In medicine it is used for rehabilitation purposes‚ for instance in Physical therapy in the prevention of disuse muscle atrophy which can
