Results A left gastrocnemius muscle of a frog (L=3.2cm in situ) was used in experiment 1 and 2‚ while a right gastrocnemius muscle of a frog (L=3.4cm in situ) was used in experiment 3. The sciatic nerve of the frog was placed over the stimulatory electrodes covered with a piece of a Kimwipe moistened with Ringer’s solution. The relationship between muscle length‚ force production and velocity of contraction was studied. Force transduced calibration In order to get a more accurate data from force

It has three phases known as the latent‚ contraction‚ and relaxation phase. • threshold - the threshold is the minimal stimulus needed to cause a depolarization of the muscle plasma membrane (sarcolemma

1. Describe the main muscle groups of the body and their function There are three main categories that the muscles in the human body fall into: • Skeletal Muscle Skeletal muscle is the foremost area of concern for a sports masseuse. The main functions of this muscle group is to move the body in a voluntary manner‚ for example‚ if you want to kick a ball you will voluntarily have to send a signal through your brain to inform the muscles in your legs to contract/flex/extend and execute the skill

These are but not limited to techniques such as: Super Sets‚ Forced Reps‚ Pyramid System and Periodization. Super Sets are when you do two exercises one after the other with no rest in between sets. Depending on the goals that you have set‚ the exercise can be for the same or different muscle groups. (Waehner‚ 2011) If you have limited time to

Slow-Oxidative (Type I) Muscle Fibres Shelby Daye Skeletal muscles are classified as striated and voluntary. They are found in muscles that maintain low-intensity contractions for long periods without fatigue. A single skeletal muscle cell is referred to as a muscle fibre. There are three types of muscle fibres found in the human skeletal muscle system including slow-oxidative fibres‚ fast-oxidative fibres and fast-glycolytic fibres. These three fibres are each defined by their biochemical capacities1
