Summarise the positive and negative effects on the skeletal and muscular systems of a young person performing contact‚ high impact and repetitive sports. There can be both positive and negative outcomes to a young performer. Positive effects can be the strengthening of the body. Negative effects can be that serious injuries can occur to the undeveloped young performer’s body and not be able to do that sport after. The skeletal system and the muscular system are both systems in the body that can

improving the performance of the muscle to gain in size. He states that creatine phosphate (high energy molecule form‚ stored within cells) that is used to supply the type 11b muscle fibers which are the fast-twitch high glycolytic‚ to give energy right away. This actually helps the athlete perform and engage more forcefully since muscular contraction fibers are already being strengthened. In fact another article also states that creatine “enhances the ability of the muscle to maintain power output during

Your heart speeds up to pump extra food and oxygen to the muscles. Breathing speeds up to get more oxygen and to get rid of more carbon dioxide. When a fit person‚ such as an athlete‚ exercises the pulse rate‚ breathing rate and lactic acid levels rise much less‚ than they do in an unfit person. As the exercise intensity increases so do the heart and respiratory rates to supply oxygen to the working muscles at a faster rate so they can keep up‚ few athletes have perfected this to a point where they

the equipment (calibration) and environment (room temperature‚ humidity). With a small number of observations and participants cost of each error is reasonably high and more difficult to detect. Muscle power and muscle force are different terms and increasing the muscle force will not increase the muscle power if the speed of the action is decreased. The power is only increased with increasing force if velocity remains constant. The formula Power (P) = Force (F) * Velocity (V) is a basis for all

Introduction: Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise‚ cause soreness‚ muscle fatigue‚ does not contribute to exercise performance‚ muscle does not use it for fuel‚ and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion.

During this coursework‚ I would be investigating the concept of relational contracting and how it is used in the real world‚ this would be followed by a full explanation of the advantages and disadvantages of relational contracting‚ supported by real case studies and how some of the advantages in turn might lead to the saving in transaction costs. Managing the relationship between various parties is becoming crucial as the industry is moving from fragmented and adversarial ways of working. Under

Intolerance r/t decreased muscle strength secondary to old age | MusculoskeletalMuscle mass is a primary primary source of metabolic heat. When muscles contract‚ heat is generated. The heat generated by muscle contraction maintains body temperature in the range required for normal function of its various chemical processes. As early as the third decade of life there is a general reduction in size‚ elasticity and strength of all mass continues throughout the elder years. Muscle fibers continue to become

well the heart; lungs and blood vessels supply oxygen and nutrients to your muscles. Cardio Respiratory endurance is also reffered to as stamina or aerobic fitness. 2. Muscular Strength Muscular strength is the ability of a muscle or group of muscles to exert a force against a resistance in a single contraction. Strength is fundamental for all sports 3. Muscular Endurance Muscular endurance is the ability of a muscle to exert a force repeatedly over an extended period of time. 4. Flexibility
