Component 3: Lab report on knee angle and jump height
For this re-sit, you will need to produce a 1300 word lab report that is related to the practical session
which investigated the relationship between knee angle and jump height. This is slightly different to
the original assessment. You will need to use the sub-headings of “Introduction”, “Results” and
“Discussion” only. Read through the following guidance to help you construct your work:
The Introduction (500)
The introduction allows you to present some background information on jump performance, the
influence of knee joint angle and muscle action.
You need to:
Introduce and explain what a vertical jump is, how it can be measured (e.g what field tests
etc) and what physiological components this represents [75 words]
List all the factors that have been shown in the literature to influence jump height
(Reference them!) [75 words]
Explain how joint angle and the use of the countermovement jump contributes to effective
jump height performance. Using academic resources, you should also briefly explain why the
length-tension relationship and stretch-shortening cycle is important. [350 words]
The Results (150 words)
The results should show the mean ±SD values for mass, height, age, jump height and knee
angle, clearly displayed as an academic table.
You will need to carry out a Pearson’s correlation coefficient analysis on the jump height and
knee angle of all participants.
You will need to describe what the results mean, this doesn’t mean just repeating what is in
the table but you need to demonstrate your understanding of the results.
The Discussion (650 words)
The ‘discussion’ section is where you explain the results and use other academic sources to support
your findings. A brief ‘conclusion’ is to be used to summarise your findings.
Explain what the results mean (i.e. did those with the greatest knee bend jump higher). [150
words]
How does this compare with the information that you reviewed in the introduction and
other literature. [250 words]
How would you use the findings from this experiment to improve vertical jump height in a
real-world scenario i.e. if you was a coach/trainer. [150 words]
