During muscular exercise‚ blood vessels in the muscles dilate and blood flow is increased in order to increase the available oxygen supply‚ to allow the muscles required to function properly. Up to a point‚ the available oxygen is sufficient to meet the energy needs of the body. However‚ when muscular exertion is very great‚ oxygen cannot be supplied to muscle fibres fast enough‚ and the aerobic breakdown of pyruvic acid cannot produce all the ATP required for further muscle contraction. During

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

INTRODUCTION Standing Broad Jump (SBJ) is a test for muscular power of the lower extremities‚ coordination of the upper and lower extremities‚ and a person’s ability to jump horizontal distances. The SBJ is a test station that has been used in official fitness tests in Singapore and has one of the higher failure rate (Wai Kit. L‚ 2014). There are many components that contribute to jump performance; velocity of the centre - of - gravity (CG) at take - off‚ jumping technique‚ and magnitude of force

Abstract The major racket sports include badminton‚ squash‚ table tennis and tennis. The growth of sports science and the commercialization of racket sports in recent years have focused attention on improved performance and this has led to a more detailed study and understanding of all aspects of racket sports. The aim here‚ therefore‚ is to review recent developments of the application of motor skills to racket sports specifically on badminton. It is evident that a great deal of scientific endeavor

Muscle Fatigue Monira Begum How muscles work and get the energy they need to work. Muscles need energy to work and move. (1) Their main source of energy is glucose. Glucose is made of a number of different types of carbohydrates (usually sugar) as well as milk and fruits. Glucose turns into other chemicals such as water and carbon dioxide which releases energy. (2)Your muscles get warm when using or burning energy. Glucose is sent to muscles through red blood cells; this is how muscles get

(a) Give generalized conclusions (in point form) according to your observation in (a). 1. systolic pressure increases when the degree of exercise increases Systolic pressure increases gradually from 115 mmHg at rest to 150 mmHg during severe exercise. When thr degree of exercise increases‚ the skeleton muscle needs more energy(ATP) for rapid contraction by carrying out aerobic respiration. The skeleton muscle required faster uptake of oxygen and removal of carbon dioxide. At the same time‚ skeleton
