1. Why is the warm up period so important?
– Helps protect against injury by improving flexibility,
avoid muscular injury; done by raising internal temp
with light activity & stretch.
2. What are the 2 components of a warm up
program?
– General – 5-10 mins. of slow jogging/stationary bike;
rate & blood flow, etc. Specific incorporates
movements similar to the movement of the sport; 8-10
mins.
3. How can flexibility be important for an athletes
– Improve athlete’s performance by
injury.
joint’s movement,
KEY
a) Flex.-Measure of ROM.
b) Stat.F-Range of possible movement about a joint and its
surrounding muscles during a passive movement.
c) Dyna.F-Available ROM during active movements and therefore
requires voluntary muscle actions.
d) Mus.Spin.-Monitor changes in muscle length.
e) GTO-Sensitive to in muscular tension & cause muscle to
reflexively relax.
f) Str.Ref.-Motor neuron causes a muscle action of previously
stretched extrafusal muscle fibers.
g) Mech.Rec.-Receptor that reacts to mechanical stresses.
h) Auto.In.-Actively contracting a muscle immediately before a passive
stretch of that same muscle.
i) Rec.In.-Relaxation that occurs in the muscle opposing the muscle
experiencing the tension.
KEY
4. Compare and contrast static and dynamic flexibility.
Which one provides a better stretch? Which one is
better for the athlete?
– S-range of possible movement about joint & muscles during
passive movements. D-ROM during active movements &
requires voluntary muscle actions.
5. Name and explain each of the 6 factors that can affect
flexibility.
– Joint structure determines its ROM. Age and sex cause young
people > old people and females > males. Connective tissue
like tendons, ligaments, fascial sheaths, capsules, and skin
may limit ROM. Weight training with limited ROM may
decrease ROM so exercise through the full available ROM of
the involved joints. Activity level cause active people tend to
be more flexible than inactive people.
KEY
6.
What are the general guidelines for stretching? (F.I.D.)
–
7.
Frequency (F)-twice a week for 5 weeks. Intensity (I)-point of mild discomfort, but not pain for 30
secs. Duration (D)-5 to 6 mins of general WU, 8 to 12 mins of sport-specific stretching, & 4 to 5
mins of stretching.
Explain the times an athlete should stretch and the benefits for each.
–
8.
Before practice & competition improves performance by
available ROM & improving
functional abilities,
likelihood of injures like strains. After practice & competition to facilitate
ROM improvements from the
muscle temp, must be 5-10 mins after for greater stretch
magnitude.
IF the hamstring is stretched which muscle will be relaxed according to reciprocal
inhibition?
–
9.
Quadriceps
What muscle would be contracted according to autogenic inhibition?
–
Hamstring
10. Name and briefly explain the four different types of stretching. Name the
duration each should be held.
–
S-Slow and constant with end position held for 30 secs, does not elicit the stretch reflex of
stretched muscle, easy to learn. B-Involves active muscular effort and uses a bouncing-type
movement in which the end position is not held, may injure muscle or connective tissues. DInvolves flexibility during sport-specific movements, similar to ballistic stretching but avoids
bouncing. PNF-Method of
muscular flexibility, usually performed with a partner and involve
