A3–AGILITY TRAINING & ACCELERATION (QUICKNESS) DRILLS
Tennis is a sport with high demands in all of the physical components including suppleness (flexibility), stamina, strength, speed and skill (Dick, 1985). When speed and skill are combined they give rise to improvements in agility and optimize fast feet on and off the court. Tennis is an explosive sport, requiring players to react to numerous emergencies with movement in multiple directions and through multiple planes of movement for short bursts of time. Movements include sprinting, side-to-side running, cutting, twisting, sliding, and quick stops and starts (Pluim & Safran, 2004).
The average point length in tennis is less than ten seconds. On average, 3 to 5 directional changes are required per point, and it is not uncommon for players to perform more than 500 directional changes during a single match or practice (Roetart & Kovacs, 2011). As well, in ‘professional players’, it was found that more than 70% of movements were side-to-side with less than 20% of movements in forward linear direction and less than 8% of movements in a backward linear direction (Weber et al, 2007). These quick movements pass through many planes of motion and create rotational and torsional forces on numerous joints and muscles at the same time. Individuals including coaches who design training programs for tennis players must keep these time frames, directions of movement and additional needs in mind when setting up footwork drills.
Square Run Drill
Arrange five cones or half tennis balls as shown in the diagram approximately
10 feet (3–4 meters) apart. Start in the middle of the square and always facing
in the same direction side shuffle step to the two front cones and back after circling them with short steps. Then proceed to the two back corner cones.
Repeat 2–3 times.
Training tips to remember when training for agility are these:
· Always start with a good athletic stance (soft knees and core switched on).
· Agility and acceleration (quickness) drills must be structured so the muscles learn to fire quickly and in a coordinated manner.
· Quickness within two steps in all directions is key in tennis.
· Agility and acceleration allow smaller athletes to be able to compete well and gives larger athletes another weapon in their arsenal.
· Agility can be gained by playing different sports and dynamic games that involve lateral movement and quick stops and starts, or by doing circuit drills that incorporate different exercises.
