Aim of TodayOxygen Transport System Warming up Cooling down
Oxygen Transport System• As you breathe in oxygen goes into you lungs. From there it goes to the heart and mixes with the blood and gets pumped around the body to the working muscles by the heart.• You can get more oxygen by: Breathing faster Breathing deeper
Oxygen debt (Credit extension)• If you perform for long time intervals it is often difficult for your breathing to supply enough oxygen to working muscles. This leads to a build up of lactic acid in your muscles, which will eventually force you to slow down. This is because your muscles will have fatigue. Lactic acid can only be removed with oxygen and until more oxygen arrives by deep and frequent breathing you will suffer from oxygen debt.
Warm UpStage Description Explanation1. Jogging Jogging twice round the To raise body temperature pitch, changing direction, and increase heart rate side stepping, jumping , ready for the activity. running. Game movements.2. Stretching Stretching quad and To increase muscle hamstring, holding each suppleness and to prevent stretch for 30 seconds. an injury3. Skill related practices Passing/volleying ball with To gain confidence with the partner, dribbling and ball and practice the skills shooting into the goal. used in the game.
Cool DownStage Description Explanation1. Jogging Slow jog once round the pitch To gently lower body temperature/Heart rate2. Stretching Stretching muscles used in the game To reduce muscle feeling stiff the next day

Credit answers• Why – The body increases it’s work rate which requires more oxygen. The body needs to use more energy to fuel the muscles.• How – deeper breathes or quicker breathes• Oxygen is breathed in through the mouth into the lungs, mixes with the blood and pumped by the heart to the working muscles.• 1 – gentle movements for 5 mins• 2 – stretching muslces used in the game• 3 – skill related drills used in the game.• Mentally and physically prepared for game. Muscles were stretched and supple allowing full range of movement and I gained confidence by practicing my shooting before the game started.
