2 Background of Volleyball Bump A 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 set up for a spikeHow to bump a volleyball…
3 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.
4 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.
5 Phase 2: Bump BallWhen 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.
7 Shoulder Muscles Stretch/Strengthen Trapezius 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.
11 Knee Muscles Strength/Stretch ExtensionRectus femoris strength- squatsRectus femoris stretch- knee flexionVastus lateralis/ intermedius/ medialis strength- knee extension, squatsVastus lateralis/ intermedius/ medialis stretch- knee in full flexionFlexionBiceps femoris strength- hamstring curlsBiceps femoris stretch- max extending the knee while flexing the externally rotated and slightly adducted hipPopliteus strength- hanging from a bar with legs flexed at the kneePopliteus stretch- full knee extension without flexing the hipSemitendinosis/semimembranosus strength- hamstring curls, leg curlsSemitendinosis/semimembranosus stretch- max extension of the knee
12 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.
