Ihave a whole lot of questions, so i hope someone can .
when you stretch a muscle, the
1muscle fibers tighten
2. blood flow decreases
3. myofibrils slide apart
4. myofibrils slide together

what type of stretching should you never do?
1. ballistic stretching
2. dynamic stretching
3. static stretching
4. non of the above

if ray makes sure to hold a stretch for 30 seconds, he is doing a
1. ballistic flexibility exercise
2. cool-down
3. warm-up
4. static stretching activity
anything , !

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )

take a nice, long walk. walk, feel the wind through your hair and your it is very relaxing.
