Study on Physiological Functions Using Chronophotographic Gun

Étienne-Jules Marey's pioneering work in time-resolved photography for studying physiology inspires a proposal for a quantitative analysis of physiological functions using similar techniques. The project involves analyzing videos to study postures, locomotion, and other important physiological parameters. Pros and cons are discussed, along with the use of high-speed cameras, tracking software, and varying mass to conduct experiments. Results and conclusions are drawn, highlighting good conclusions that align with theoretical predictions. Points for discussion include the jumping distance of grasshoppers and the forces acting on them.

1. 17. CHRONOPHOTOGRAPHIC GUN TeamCroatia Opponent: Marko ari

2. PROBLEM TEXT tienne-Jules Marey pioneered the use of time resolved photography to study physiology of humans and animals, and in particular their postures and locomotion. Propose a quantitative study of important physiological functions or parameters that would require analysis of similarly taken videos. 2

3. THEORY Pros: Cons: Sketch Explained the anathomy 3

4. EXPERIMENT Pros: Cons: High speed camera Tracking software Multiple measurements Varying the mass 4

5. RESULTS AND CONCLUSION Pros: Cons: Good conclusions Results agree with theory No units on graphs 5

6. POINTS FOR DISCUSSION Jumping distance of different grasshoppers (smaller or larger)? What forces are acting on the grasshopper (sketch)? 6
