| Question | Answer |
|---|---|
| What is the Fick Equation? | HR x SV x (a-v)O 2 diff |
| What does aerobic exercise yield at slower rates? | ATP |
| What is maximal oxygen uptake? | The max oxygen that can be used |
| How do you find gross efficency? | Mechanical power output/Metabolic power output x 100% |
| What is exercise efficency? | Biological work vs mechanical work |
| What is running economy? | The oxygen required to run at a given submaximal speed |
| In the study by barnes and kilding, who will diksplay better running economy? | The person who consumes less oxygen at each speed |
| What is the anaerobic threshold | Workload where body must rely on anaerobic energy sources |
| What is the recommended test for aerobic performance? | 1 minute ramp test |
| Who reaches anaerobic threshold at a higher V02max out of a trained and untrained athlete? | Trained, |
| What is the benfit of a higher anaerobic threshold? | The athlete can exercise at a higher intensity before lactate spikes |
| What is the best field based test for aerobic performance | YOYO intermittent test |
| Why is the YOYO test reliable? | Derives V02 max and velocity at V02 max |
| Why is the YOYO IRT2 more sports specific? | ↑ muscle lactate and ↑ PCr depletion |
| What does a shift in the curve down and / or to the right indicate for anaerobic thresholds | The athlete can exercise at a greater intensity for a given blood lactate |
| What does a shift in the curve up and / or to the Left indicate for | The athlete is exercising at a lower intensity for a given blood lactate |
| Who out of a marathoner and a sprinter would have a higher LT? | Marathoner, due to improved lactate clearance |
| T OR F: Lower intensity, longer duration are just as effective as influencing V02 max as higher intensity exericse? | T |
| How could strength training influence V02 max? | Increase neuromuscular capacity which leads to an increased endurance performance. |
| What is the best strength training intensity to improve exercise economy? | High intensity low rep, plyo work |
| Does stroke volume increse or decrease following endurance training? | Increase |
| What happens to HR max after endurance training? | Remains unchanged |
| Does maximal ventilation and tidal volume increase or decrease following endurance training? | Increase |
| T OR F: Slow twtich muscle fibres change substantially following endurance | F |
| Does capillarisation occur at a greater rate in type 1 or 2 muscle fibres? | type 1 |
| Wht happens to mitochondrial density after training? | Increases greatly |
