voluntary muscle the different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction. It is generally accepted that muscle fibre

Vibration- Rotation Spectroscopy of HCl and DCl Purpose: To determine the fundamental vibration frequency and bond length for H35Cl‚ H37Cl‚ D35Cl‚ and D37Cl and to compare the isotope effects to theoretically predicted values. Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the

In the town of el Valle there were always golden frogs‚ she liked those frogs so much that she went on and established a research site so later she could study them. Lips decided she wanted to study the local frogs

1. Based on the results of your investigation‚ what conclusions can you draw about the relationship between a muscle’s workload and its threshold of stimulation? The conclusions I was able to determine about the muscle’s workload and its threshold of stimulation was that the threshold stimulus will increase by one when the workload doubles. The muscles can hold a higher workload if they originally have a higher threshold of stimulation with no workload at all. 2. Why would a muscle’s threshold

and unfamiliar exercise‚ particularly which involves eccentric muscle actions can cause muscle damage and lead to delayed-onset muscle soreness (DOMS)‚ which may impair performance. This is due to the high force features of eccentric contraction (Starbuck & Eston‚ 2011). It can also cause muscle shortening‚ swelling and loss of strength in the muscles. Injuries commonly occur during eccentric loading of the muscle; that is‚ when the muscle is contracting while it is lengthening. (LaStayo‚ et al.‚ 2003)

Biceps Femoris Muscle The Biceps Femoris is a muscle of the posterior (the back) thigh. As its name implies‚ it has two parts‚ one of which (the long head) forms part of the hamstrings muscle group. Origin and insertion It has two heads of origin; one‚ the long head‚ arises from the lower and inner impression on the back part of the tuberosity of the ischium‚ by a tendon common to it and the semitendinosus‚ and from the lower part of the sacrotuberous ligament the other‚ the short head‚
