Question | Answer |
Name the three energy systems | Lactic Acid (LA) System//Aerobic Energy System//Creatine Phospate (CP) Energy system |
How long does the CP system last? | provides immediate energy for 8-10 secs |
Lactic Acid energy system is it aerobic or anaerobic? | anaerobic. It provides fuel for 2-3 mins of reformation of ATP. |
Match Lactic Acid with definition | Short term - high intensity - anaerobic - employs white fast twitch muscle fibres |
Match Aerobic Energy system with | long term - aerobic - employs red slow twitch muscle fibres |
How long does the Aerobic energy system last? | as long as there is sufficient oxygen to meet demand. |
Which fuels does the Aerobic Energy system use? | Glycogen from liver//fat stores from body//oxygen we breathe// and as a last resort protien from muscle. |
Which three food groups provide us with necessary energy | carbs//fats//protiens |
what does ATP stand for? | Adenosine Tri-phosphate |
Cp system is used in which activity | 100m sprint |
LA system | 400m sprint |
aerobic system | walking//jogging//cycliing//distance running |
average blood pressure reading for a healthy adult is | 120/80 |
average heart BPM for a healthy adult is | 60-80 bpm |
What is OBLA? | The onset of blood lacate accumulation |
The lactate threshold for untained people occurs | around 50 - 60% of their VO2 max |
The lactate threshold for endurance athletes can occur | around 70 - 80% of their VO2 max |
EPOC refers to | excess post exercise oxygen consumption |
EPOC is required to perform 3 tasks. What are they? | Replacement of ATP Removal of lactic acid Replinishment of myoglobin with oxygen |
What is the alactacid oxygen debt component? | Fast component of recovery that converts ADP back into ATP & PC |
What is the lactacid oxygen debt? | The slow component of the recovery process that oxidises lactic acid into CO2 and H2O and converts Lactic acid into glycogen for storage |
Restoration of muscle phosphagen stores takes place | When exercise has finished |
Lactacid oxygen recovery takes place | As soon as lactic acid appears in the muscle cell |
Anaerobic glycolysis takes place | in the sarcoplasm of the muscle cell |
Aerobic glycolysis takes place | in the mitochondria |
An equation which summarises the CP system | ADP + CP - ATP + Creatine |
strength uses which muscle fibres? | white fast twitch |
strength training uses which energy system | lactic acid |
endurance training use reps of | 15-25 50-60% 1RM |
endurance training uses which energy system? | aerobic |
which muscle fibres are used in endurance training? | red slow twitch |
Immediate muscle soreness is due to | the effects of an increase in muscle acidity |
muscular endurance training provides | developmenht of red slow twitch muscle fibres//muscle tone//aerobic and LA energy systems//capillarisation increase in worked muscles//neuromuscluar efficiency//increase no and size mitochondria |
Muscle soreness felt a day after activity is a result of | structural damage within the muscle cell membranes |
