Energy system
Standing long jump
Due to the quick burst of energy required for the standing long jump, the anaerobic system is utilized. More specifically, this activity utilizes the ATP-PC system. In order for a maximum distance to be achieved, an explosive burst of the entire lower body is required. This indicates the initial usage of an anaerobic system as the action is under 10 seconds.
Stepping Test
Unlike the standing long jump, this test requires the use of both energy systems - Anaerobic system & Aerobic system, and more specifically all pathways (ATP-PC, Glycolysis, Cellular respiration). Within the initial start of the test, the ATP-PC system is used as muscles only store small amounts of ATP and creatine phosphate. After …show more content…

Muscle fibres
Standing long jump
During this activity, the fast-twitch fibres were used. Fast twitch fibres are muscle fibre types which are used without oxygen (anaerobic), and allow for extremely quick tension and relaxation. Due to the standing long jump requiring and immediate burst in the lower body, the muscles quickly tense and relax, making them fast twitch fibres. More specifically this activity uses type IIB fast glycolytic. This is due to the high force production and high anaerobic capacity allowing a person jump as far as possible.
Burpee and stepping
Due to these two exercises being endurance oriented, they both utilize slow-twitch muscle fibres. More specifically the type I - slow oxidative muscle fibre. Slow twitch fibres (type I) have a high aerobic capacity which allow us to continue the burpee and stepping test for an extended period of time. Furthermore, it is highly efficient in terms of energy and has a high fatigue resistance. With these factors and a slow contraction speed, this makes the type I fibre the most efficient system for these two exercises/tests …show more content…
Through the utilization of my anaerobic system I was able to produce and explosive jump resulting in an “average” performance (215 cm). In the stepping test, which used a greater amount of the aerobic system, my measured heart rate was approximately 60 heart beats within a minute (score of 88). Through this it, is evident that my aerobic system was efficient placing me in the “good” range of the benchmark. Lastly the burpees test relied on endurance, and how long your body can handle the activity. With 41 burpees I was placed in the very good range. The results I achieved within all the tests were greater than I hypothesised. However my aerobic system was much more efficient than my anaerobic
