Any TWO of the following – Sport choice – Tennis
Dynamic stretching
- Involves continuous movement through range of motion to prepare muscles for activity. This occurs because the controlled movements gradually increase muscle temperature and blood flow. A tennis player performing leg swings leads to improved hip flexibility and hamstring length. The result is enhanced stride length during court coverage and the production of more powerful serves through increased shoulder rotation. As a result, the athlete can cover the court more efficiently and hit winners from wider positions.
PNF stretching
- Combines passive stretching with isometric muscle contractions against resistance. This works by overriding the stretch reflex, allowing muscles to relax and lengthen further. A tennis player using PNF for shoulder flexibility creates greater racquet head speed during groundstrokes. The reason for this is increased range of motion at the shoulder joint enables fuller backswing and follow-through movements. Consequently, the athlete generates more power and accuracy in shot placement whilst reducing injury risk.
Static stretching
- Involves holding muscles in lengthened positions for extended periods. This happens when muscle fibres gradually relax under sustained tension. A tennis player performing static calf stretches results in improved ankle flexibility for better court movement. This mechanism allows enhanced push-off power during explosive directional changes. Therefore, the athlete achieves faster acceleration and deceleration, improving reaction time to opponent shots and reducing lower limb injury risk.
Ballistic stretching
- Uses bouncing movements to force muscles beyond normal range of motion. This works through momentum forcing muscle lengthening beyond typical limits. A tennis player using controlled arm circles causes increased shoulder mobility for overhead shots. This process enables greater racquet extension during serves and smashes. As a consequence, the athlete generates higher ball velocity and improved court angles whilst maintaining technique consistency.
