PDHPE - Training Types and Methods. Cards: HSC PDHPE Core Two - Characteristics of the Learner. What is the mnemonic for remembering the characteristics of the learner?
Personality An individual's characteristic way of behaving Traits. Anaerobic System (Anaerobic glycolysis) Energy Pathways. Energy Pathways for Exercise - Aerobic and Anaerobic Metabolism. How the body converts food to fuel relies upon several different energy pathways.
Having a basic understanding of these systems can help athletes train and eat efficiently for improved sports performance. Sports nutrition is built upon an understanding of how nutrients such as carbohydrate, fat, and protein contribute to the fuel supply needed by the body to perform exercise. These nutrients get converted to energy in the form of adenosine triphosphate or ATP. It is from the energy released by the breakdown of ATP that allows muscle cells to contract. However, each nutrient has unique properties that determine how it gets converted to ATP. Carbohydrate is the main nutrient that fuels exercise of a moderate to high intensity, while fat can fuel low intensity exercise for long periods of time.
Energy Pathways Because the body can not easily store ATP (and what is stored gets used up within a few seconds), it is necessary to continually create ATP during exercise. Source. A2 Energy Pathways. Anaerobic and aerobic Energy Pathways. Energy production is both time and intensity related.
Running at a very high intensity, as in sprinting, means that an athlete can operate effectively for only a very short period of time where as running at a low intensity, as in gentle jogging, means that an athlete can sustain activity for a long period of time. There is a relationship between exercise intensity and the energy source.
Energy Pathways Matthews (1971)[2] divides the running requirements of various sports into the following "energy pathways": ATP-CP and LA, LA-02, and 02. ATP - Adenosine Triphosphate: a complex chemical compound formed with the energy released from food and stored in all cells, particularly muscles. When working at 95% effort these energy pathways are time limited and the general consensus on these times are as follows: The result of muscle contraction produces ADP which when coupled with CP regenerates ATP. VO2 max test. Home > Fitness Testing > Tests > Aerobic Endurance > VO2 max The VO2max test is the criterion measure of aerobic power in athletes.
Described here is the method to measure VO2max directly by indirect calorimetry. equipment required: Oxygen and carbon dioxide analyzers, ergometer on which workload may be modified, heart rate monitor (optional) and a stopwatch. Expired air may be collected and volume measured via Douglas bags or a Tissot tank, or measured by a pnuemotach or turbine ventilometer. procedure: Exercise is performed on an appropriate ergometer (treadmill, cycle, swim bench etc.). The exercise workloads are selected to gradually progress in increments from moderate to maximal intensity.
The Dangers Of Dehydration. Dumbbell Exercises Complete with Animated Diagrams. Dumbbell exercises form an integral part of most strength training programs.
They can be used to develop the various different elements of strength such as maximal strength, hypertrophy or muscle mass, explosive power and strength endurance. Why Free Weights? Free weights such as dumbbells activate smaller stabilizing muscle groups to control the exercise. Resistance machines on the other hand, tend to work muscle groups in very strict planes of movement. The downside of this very strict movement is that while some muscle groups will become significantly stronger, other, smaller muscles are neglected.
The other advantage dumbbell exercises have over machines is that they fit around your body so the movement can be performed correctly. Athletes typically favor dumbbell exercises over machines as they can replicate sport-specific movements more accurately. Exercises By Muscle Group The dumbbell exercises below have been divided into the major muscle groups of the body. Flat Chest Presses 1. HSC PDHPE - Anxiety and Arousal. Supplements. Vitamin and mineral supplementation continues to be a contentious issue amongst health professionals.
The common catch-cry of the medical community is that vitamins and minerals are adequately available from our food. It’s hard to appreciate the credibility of this advice, when it is delivered from a profession that receives negligible nutrition training. In Australia, this claim contrasts in stark hypocrisy against laws prescribing the mandatory fortification of bread with thiamine and salt with iodine. In addition, folic acid supplementation in pregnant women is a recommended requirement to protect an unborn child from developing spina bifida. But we’re meant to be getting that from our foods, right? The inconvenient reality is that food ‘ain’t what it used to be. Whilst sustainable agricultural practices such as biodynamic farming aim to restore our soils to health, we have considerable work to do before this option is universally adopted and available to everyone. Vitamin C. Oper Test - 12 minute run to assess your vo2max. Testing and measurement are the means of collecting information upon which subsequent performance evaluations and decisions are made but in the analysis we need to bear in mind the factors that may influence the results.
Objective The Cooper Test (Cooper 1968)[1] is used to monitor the development of the athlete's aerobic endurance and to obtain an estimate of their VO2 max. Required Resources To undertake this test you will require: 400 metre track Stopwatch Whistle Assistant.
