The guidelines for which warm-up activity include carryout out 5 to 10 repetitions for each movement, progressively increase the ROM on each repetition, increased the speed of motion on subsequent sets, and contracting the muscles while moving through the ROM.
a. stating stretching
b. dynamic stretching
c. PNF stretching
d. free weight exercises
e. ballistic stretches
Answer: b. dynamic stretching
Dynamic stretching is correct because this involves 5-10 repetitions of increased range of motion. There are also precautions for dynamic stretching. One should move progressively through the ROM, move deliberately but avoid bouncing and should not sacrifice good technique for additional range of motion.
Static stretching is incorrect because these stretches are held for time.
PNF stretching is incorrect because these do not involve increased range of motion or speed throughout the set.
Ballistic stretches is incorrect because these stretches begin with fast movements.
