all members in a group‚ not only because people have different physical traits‚ but also different diet and living habits. There are three major body types: Ectomorph‚ endomorph and mesomorph. People who are described as Ectomorphs usually have lean muscle mass; they have small frames and do not gain weight easily‚ and therefore‚ have a slim appearance. Ectomorphs have long limbs‚ narrow hips and small shoulder width; their muscule strength is usually unable to afford heavy training‚ and therefore‚

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

Exercise physiology Touch football is a game derived from Rugby League that requires the opposition to tag or touch the opponent to stop their progress. This assignment is centred on exercise physiology in relation to touch football and my performance in the position of centre. Exercise physiology is the study of the function of the human body during various exercise conditions. Throughout a game of touch football our bodies rely on various energy systems to meet energy demands. Whilst addressing

The Arctic wolf’s skeleton system is made for them to run‚ jump‚ and catch their prey. The part of the wolf’s skeletal starts with the part of the body that has bones of the limbs‚ skull‚ and a deep chest. 1. The limbs of the wolf include the legs and toes.
