The Effect of Gender Recovery in Spinning

The Effect of Gender Recovery in Spinning

Rossana F. and Kalile E. Rossana F. and Kalile E.

Introduction

Everyone gets dizzy at least once in their life. There are many ways of getting dizzy and sometimes it takes a lot of time to get over it.People who are used to spinning might get over dizziness faster.

Effect in Your Body After Spinning

Around Several Times +Symptoms:

Dizziness

Vertigo

Vomiting

Headaches

Vision (blurry)

Reactions

Proper Signal are not transmitted to the brain

Ear will not be able to maintain balance:

-Canals tell the brain the head is moving/rotating > fluid called endolymph (motion sensor with little hairs)

- constant rotational velocity > endolymph no longer pushes to the cilia (making the brain think the head has stop moving)

- Instant you stop (endolymph travels in a circle in the semicircular canal but because you were spinning as well) unable to detect the spin / forced to stop

- cilia > causes your brain to suddenly start thinking your head is spinning in the opposing direction / despite is not

Eyes will start moving in fast speed (blurry)from side to side, until the recovery...

How to Prove It?

Experiment Purpose: We want to find out what gender recovers faster after spinning

Hypothesis: If athletes can recover faster than none athletics, then the genders will affect the time of recovery

Independent: Male and Female

Dependent: Amount of time of recovery

Constant: # of spins

How we measured their reaction time? After spinning around ten time, we time how much it took for the eyes to stop moving...

Data

*They all do sports* Had to spin 10 times > the

reaction was measured with a timer... after their eyes stopped

moving we also stop the timer & record the information!

Graph

90%

*Percentage of the speed and time of recovery for both Genders From 10%

to 100% Males recovered 90% more than females..

Conclusion

After doing this experiment we found out that males recover faster than females...!!!
