Background of Volleyball BumpA volleyball bump is also known as a passIt is the first contact with the ball following a

serve from the other teamIt is usually hit close to the net so it can be

Muscle ContractionsWhile performing the bump eccentric and

isometric contractions occurEccentric contractions is a contraction in which the

muscle lengthens in an attempt to control the motion occurring at the joints that it crosses.

Isometric contractions is a type of contraction with little or no shortening of the muscle resulting in no appreciable change in the joint angle.

Phase 1: Pre-BumpPlace your feet flat on the ground and

spread equally apart. Stand stationary, with your knees slightly bent.

Extend your arms straight out with your palms supinated. Place one hand overlapping the other and press your thumbs side by side.

Phase 2: Bump Ball

When bumping allow the ball to bounce off of your forearms. If you need to give the ball more of a boost, bend down by flexing your knees and push up by extending the knees.

Phase 2: Shoulder MusclesJoint- shoulder girdleAction- elevationAgonist muscles-trapezius upper & middle fibers,

rhomboids, levator scapulae.Innervation- spinal accessory nerve and dorsal

scapula nerve.

Page 7: Volleyball Bump

Shoulder Muscles Stretch/StrengthenTrapezius exercise- shrugs, bent rows, dead liftsTrapezius stretch- use one hand to pull the head

and neck forward into flexion. Levator scapulae exercise- shoulder shrugsLevator scapulae stretch- rotating the head

approximately 45 degrees to the opposite side and flexing the cervical spine actively while maintaining the scapula in a relaxed, depressed position.

Rhombiods exercise- chin ups, dips, bent over rowsRhombiods stretch- passively moving the scapula

into full protraction while maintaing depression.

Phase 2: Elbow MusclesJoint- radioulnar joint.Action- elbow extension, supination.Agonist muscle- triceps brachii

(long, lateral, and medial heads), supinator, anconeus.

Innervation- radial nerve.

Page 9: Volleyball Bump

Elbow Strength/StretchTriceps brachii strength- push ups, dips, bench

press, over head presses, tricep curlsTriceps brachii stretch- shoulder and elbow in

maximal flexionAnconeus strength- any elbow extension exercise

against resistanceAnconeus stretch- maximal elbow flexion

stretchesSupinator strength- hammer exerciseSupinator stretch- forearm is maximally pronated

Phase 2: Knee Muscles

Joint- knee joint.Action- flexion and extension of knee.Agonist musclesExtension- rectus femoris, vastus intermedius, vastus

lateralis, vastus medialis.Innervation- femoral nerve.Flexion- biceps femoris, popliteus, semimembranosus,

semitendinosus. Innervation- tibial nerve, sciatic nerve (tibial division.)

Knee Muscles Strength/StretchExtension Rectus femoris strength- squats Rectus femoris stretch- knee flexion Vastus lateralis/ intermedius/ medialis strength- knee extension, squats Vastus lateralis/ intermedius/ medialis stretch- knee in full flexionFlexion Biceps femoris strength- hamstring curls Biceps femoris stretch- max extending the knee while flexing the

externally rotated and slightly adducted hip Popliteus strength- hanging from a bar with legs flexed at the knee Popliteus stretch- full knee extension without flexing the hipSemitendinosis/semimembranosus strength- hamstring curls,

leg curls Semitendinosis/semimembranosus stretch- max extension of the knee

Laws of MotionLaw of inertia- the resistance of any

physical object to a change in its state of motion or rest.

- The volleyball comes over the net down towards the person that is going to bump it and the person hits the ball back up into the air.
