You and another responder find an unresponsive adult on the floor in the locker room. you size up the scene, form an initial impression and perform a primary assessment. you find the victim is not moving or breathing, but has a pulse. you should summon ems personnel, then:

Give ventilation's at a rate of 1 about every 5-6 seconds.

Explanation: Cardiopulmonary resuscitation (CPR) is a lifesaving technique useful in many emergencies, including a heart attack or near drowning, in which someone's breathing or heartbeat has stopped. Both trained and untrained personnel can perform CPR.

If you're not trained in CPR, then provide hands-only CPR. That means uninterrupted chest compressions of 100 to 120 a minute until paramedics arrive without gibing rescue breaths.  

If you're well-trained and confident in your ability, check to see if there is a pulse and breathing. If there is no breathing or a pulse within 8-10 seconds, begin chest compressions. Start CPR with 30 chest compressions before giving two rescue breaths.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
