• i.e. same person will mark all papers related to the squat
• Please do your own work, no plagiarising or you will get zero!
Guidelines
Assignment Checklist!
?Intro/background to your exercise (1-2 pages double spaced)
• Why is this exercise commonly used, why is it an important exercise, what is it used
for (strength, hypertrophy, athletic development, etc.), what problems/injuries
could develop if done incorrectly?
?Step-by-step bullet point list of instructions (1 page)
• Lie on your back on a flat bench
• With an overhand grip (grip is important to include) grab the barbell with your
hands approximately shoulder-width apart……
• Make sure your feet are firmly on the ground, back in contact with the bench
?Include a picture of each phase of the movement
• Attach screen caps of your analysis
?Include graphs and results/calculations
?Complete an information table
?Conclusions (1 page)

You have to perform a video analysis (not nearly
as detailed as HLSC 4471):
Track the bar during 5-10 reps of your exercise (download
the free phone app “barsense”)
• If you do not have a smartphone (apple or android), work with a
classmate!

Perform a Video Analysis of your Exercise

Perform a Video Analysis of your exercise
Conclusion:
• In biomechanics we were focused on the person or “athlete”
• Now, we are going to focus on the bar (an important part of
performance and coaching)
• Bar speed (peak or average) and bar path/movement is vital to
improving training outcomes
• Now that you know bar path, what adjustments (coaching cues)
need to be made to the person to improve the analysis?
• What did you notice in your video that could be improved?
