EXAMPLES OF CORE EXERCISES FOR TENNIS AN EXCERPT FROM THE NEW BOOK, DEVELOPING THE CORE The following is an exclusive excerpt from the new book, Developing the Core, the latest release in the NSCA’s Sport Performance Series with Human Kinetics. All text and images provided by Human Kinetics. Tennis is a physically demanding and complex sport that requires a high level of strength, power, speed, agility, coordination, balance, endurance, and flexibility. The players who are most successful are the best all-around athletes. Having strong, powerful, efficient core muscles is paramount to success in the sport. Tennis is a ground-based sport that requires efficient transfer of energy from the ground up through the trunk and finally out to the arms and racket and into the tennis ball. The conditioning of the core muscles helps improve energy transfer, resulting in greater movement speed, agility, and power production into the strokes (serve, forehand, backhand, and volley), while also reducing kinetic chain weaknesses and the likelihood of injuries. STABILITY BALL SUPINE BRIDGE (FIGURES 1 AND 2) Lie faceup on the floor, with hands palms-down at your sides, knees bent at a 90-degree angle, and the heels of your feet on a stability ball. Keeping your back straight, lift your hips off the floor. Your 4 2014 EVENTS BARBELL ROLLOUT (FIGURES 4 AND 5) Load a pair of small plates (five-pounders work well) onto the ends of a barbell. Grasp the middle of the bar with an overhand, shoulder-width grip, and kneel down so your shoulders are directly over the bar. Your upper back should be slightly rounded, with your butt off the floor as high as possible. Keeping your knees fixed on the floor and your arms taut, roll the bar forward as far as comfortably possible without allowing your body to touch the floor. Reverse direction by forcefully contracting your abs, returning along the same path back to the start position. Repeat for the desired number of repetitions. GLUTE-HAM RAISE (FIGURE 6 AND 7) Adjust the foot plate on a glute–ham bench for stability and comfort so that the lower thighs are pressed against the front rollers, with the knees resting on the supports below. From a kneeling position, the torso should be completely upright; the arms can be folded across the chest; the hands can be placed lightly on the back of the head; or the arms can be placed overhead, depending on the level of intensity desired. Slowly lean forward, flexing at the hip joint and keeping the back straight, until the torso is parallel with the floor, and then return to the start position. Repeat for the desired number of repetitions. Developing the Core features several other core exercises for basketball, along with exercises for baseball/ softball, football, golf, ice hockey, soccer, swimming, tennis, track and field, volleyball, and wrestling. The book is now available in bookstores everywhere, as well as online at HumanKinetics.com or at NSCA.com.
