Medicine ball workouts that can do wonders for your running velocity and powerWalt Reynolds takes us through some medicine ball drills. Most medicine ball drills involve lifting, throwing, and catching the ball, but the real focal point for such activities is the muscular 'corset' that surrounds the junction between the trunk and the legs. This meeting point, called the 'core' area of the body, is coordinated and held together by the abdominal, spinal erector, hip flexor, and gluteal (buttock) muscles. This central region is also called the 'power zone' of the body, because force 'moves' through this area, from one leg to the other during the act of running, and also because the core muscles must stabilise the body during footstrike so that unnecessary motions are minimised, and all the power created by the hip and leg muscles can be used to drive the body forward. Core strengthMost runners focus on the core area at least to a small extent in their training by carrying out conventional abdominal and low back exercises such as crunches and back extensions. However, during the running motion, the amount of active trunk flexion (carried out by the abdominal muscles) is negligible, as is the extent of trunk extension (a function of the low back muscles and gluteal). Compared with direct flexion and extension, there is much more rotational action in the trunk during running. Yet most runners ignore workouts that would improve the rotational strength of their core muscles. Medicine ball training, however, can give you additional specific strength, which can be used directly during your workouts and races to improve your running velocity and overall power. The following group of exercises can provide runners competing at all distances with improved core strength. Typical training weights for medicine balls range from two to 15 pounds. Larger balls (up to 25 pounds or so) are used by certain strength athletes (weightlifters, football players, bodybuilders) but are unnecessary for runners. Most runners will do very well with a set of three balls that weigh about two, four, and six pounds (one, two, and three kilograms, respectively).
The exercises1. The standing trunk twist (hammer twist)Muscle groups emphasised: Hip and leg muscles, abdominal and oblique muscles, and spinal erectors. Value for runners: This exercise develops dynamic stability strength for all of the core muscles in a standing posture, making the exercise more specific to running than many of the conventional abdominal and low back exercises that are performed in a seated position. Strong core muscles provide for an upright and economical running posture, as well as a strong anchor point for the propulsive muscles in the legs. Weight of ball: Two pounds for beginners, four to six pounds for advanced athletes. Other equipment: A towel. Instructions:
2. Hanging body flexMuscle groups emphasised: Abdominal, oblique, and hip flexor muscles. Value for runners: This exercise strengthens the integrative action of the muscles, which raise the thighs and stabilise the pelvis. This provides for a powerful knee drive and an economical running posture. Weight of ball: Two pounds for beginners, four to six pounds for advanced athletes. Other equipment: A horizontal/chin-up bar. Instructions:
3. Walking trunk twistMuscle groups emphasised: Hip and leg muscles, abdominals, obliques, and spinal erectors. Value for runners: This exercise develops stability of the core muscles, much like the hammer twist (exercise 1), but the walking twist also incorporates the integrated muscular action required during rhythmic movement. As the right leg moves forward, the trunk twists to the right, following the same oppositional pattern found in running (right leg forward, left arm forward). The added momentum gained by swinging the ball creates increased tension in the stabilising core muscles, thus strengthening them. Weight of ball: Two pounds for beginners, four to six pounds for advanced athletes. Other equipment: A towel. Instructions:
4. Jump and pick upMuscle groups emphasised: The hip and leg muscles. Value for runners: This exercise activates both the extensors and flexors of the hip during the jumping phase of the drill and thus improves explosive leg power for both the push-off and leg swing or knee-drive portions of the running stride. Weight of ball: Two pounds for beginners, four to six pounds for advanced athletes. Training note: To lessen the chance of injury, perform this drill on a resilient surface such as a wood floor, synthetic track, or grass. Instructions:
5. Knee throw and lungeMuscle groups emphasised: Hip flexors and quadriceps are utilised for the throwing action, quadriceps, gluteals, and hamstrings are used for the lunge, and core stabilisers are involved in both the throw and the lunge. Value for runners: This exercise develops explosive knee lift, eccentric leg strength, and coordination. The knee drive action is followed immediately by an energy-absorbing landing in the lunge position. This combination of throwing and lunging requires both strength and coordination to complete. Weight of ball: Two pounds for beginners, four to six pounds for advanced athletes. Instructions:
6. Squat, throw, fall, and chaseMuscle groups emphasised: Leg muscles, abdominals, spinal erectors, and shoulders are utilised for the squat and throw actions. Leg, abdominal, chest, and shoulder muscles are stressed during the fall and chase movements. Value for runners: This drill is the most dynamic of the six exercises. The squat and throw actions develop overall power in the muscles of the hips, legs, back, and shoulders, muscles which contribute to a strong push off and proper posture during running. The fall action improves coordination and whole-body control, as well as upper torso, abdominal, and leg strength. Although some runners may laugh at the idea of practising falling, knowing how to fall can prevent injuries during workouts and races. Most runners will fall at some point in their careers, and for runners in more northerly areas, where ice and snow cover the roads during the winter, slipping and falling are commonplace. Also, it is important to be able to recover from falls in race situations (remember Mary Slaney's unfortunate tangle with Zola Budd and subsequent tumble during the 1984 Olympic Games?). The chase part of the exercise teaches you to get back on your feet as quickly as possible after a spill and develops strength and coordination in the shoulders, chest, abdominal area, back, hips and legs. Weight of ball: Four pounds for beginners, six pounds for advanced athletes. Training note: Perform this drill on grass or another soft surface to minimise impact forces. Allow yourself at least 15 to 20m of space to sprint forward during the chase action. Instructions:
General training guidelines for medicine ball workoutsMedicine ball exercises represent a form of strength training and are typically performed with other strength exercises when you are fresh and non-fatigued. Perform all twisting and lifting exercises slowly and deliberately while you are learning the movements. After a few training sessions, the actions may then be speeded up to a moderate speed but remember to maintain good control at all times. Focus on developing good form while using light balls early on; progress to heavier balls after three to four weeks. Core strengthening exercises can be carried out frequently (four to six times per week) for brief periods (10 to 15 minutes). The sample programme given below is a guide for including core exercises in your overall training programme (many other programs are possible). Core exercise sample programme
