The Biomechanics of a tennis forehand shot
- Hold racquet in dominant hand with other hand on the throat
Bring the racquet back - Level to your head
- not too low, not loo high
Hand on the throat is released
- Legs shoulder width apart
An activity that involves muscular movement, with the correct degree of muscular control, to complete a reasonably complex predetermined task. (Amezdroz, 2010).
Shoulders turned sideways to the ball
- Shoulders open by turning and taking the racquet back
Ensure wrist is locked
Biomechanics can be described as the "study of how living things move, and of the efficiency of the movement in particular" (Amezdroz, 2010).
After calculated approach of the ball - adjust yourself into the correct position
Force and Momentum
drop racket below level of ball with bending the elbow
Information processing
Eyes locked on the ball
Force
After impact continue arm extention around the body by whipping wrist
Hit the ball in the striking range or comfortable distance
- Discrete - Has a distinct beginning and end.
- Continuous
- Serial - Puts together several discrete tasks to form a continuous skill
- Fine Motor - The movement of small muscle groups
- Gross Motor - The movement of large parts of the body/ whole body
- Fine and Gross Motor Combined
"The pushing/ pulling or hitting/ throwing action which is applied to an object to start movement, stop movement or cause changes in movement" (Amezdroz, 2010)
- The racquet has zero force on the ball
- Once hit the force on the ball increases when it becomes distorted.
- Decreases when the ball returns back to original shape
Discrete
- A starting shot
- Beginning - throwing the ball up
- End - follow through at the end
Bring racquet to the other side of the body
Arm extended
Gross Motor
- Performing a forehand shot
- Open Skills - Performed in an unpredictable environment
- Closed skills
- Learning open and closed Skills
- Loco motor
- Non- Loco motor Skills
- Combined loco motor and non - loco motor skills
Fine Motor
- The movement of the feet and hands
Serial
- Performing a forehand shot on the run
use the wrist to keep racquet laid back
Open Skill
- The ability to quickly prepare for a certain shot in a short amount of time.
Stay locked and balanced
Tennis ball returned to original shape after being distorted
Momentum
Relation to tennis
Force gained by a moving object
A distorted tennis ball on racquet
Tennis ball has nonzero momentum
- qucikly process the opponents shot - what shot they did and where will the ball land
Things to consider
Low force therefore the momentum is not as fast
Tennis ball slow making it easier to hit
Is the ball going to the right or left?
Does the ball ave topspin?
What shot is required to return the ball?
Amezdroz, 2010
High force therefore fast momentum
Tennis ball faster making it harder to hit
"The instant meeting of object or of bodies in which each exerts a force upon the other, causing the exchange of energy or momentum" (Isenbert, 2016)
"Change of momentum that occurs when a force is applied to an object "
When the racquet and ball collide together and the ball compress agaisnt the string
Racquet - applying maximum force will change the momentum of the tennis ball
The spot of the racquet that is able to give the best return serve.
The sweet spot is the middle of the racquet head
"An object responsiveness or its resistance to attempt to change its motion"
The ability to be stable when performing a skill
"A body will continue in its state of rest or uniform motion unless acted upon by an applied force"
Body must be stable to perform a good forehand shot
Key to have control of the bodies movement execute the shot
1st Week - Forehand shot
The quality of being correct or precise
- Look at the height of racquet
- Angle of the racquet
- Lock wrist
- Follow through
- Position of your body
- Movement
When a tennis ball is hit by the racquet
The racquet is the applied force
Very important for a forehand shot
When accurate the forehand can be hard for the opponent to hit.
