Shane's target heart rate zone is 130 - 168. during a race, he checks his wrist monitor, which indicates that his heart rate is currently 142. which of the following will him get the most productive work out, based on the information he has gathered? a) take a water break and reduce his heart rate. b) decrease to a job then run again. c) keep running at the same speed and intensity d) walk one minute, then begin running at the current pace

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 )
