The PEP Program: Prevent injury and Enhance Performance
This prevention program consists of a warm-up, stretching, strengthening, and sport specific agilities to address potential deficits in the strength and coordination of the stabilizing muscles around the knee joint. It is important to use proper technique during all of the exercises. The coaches and trainers need to emphasize correct posture, straight up and down jumps without excessive side-to-side movement, and reinforce soft landings. This program should be completed 3 times a week. This program should take approximately 15 – 20 minutes to complete. Along side each exercise you will notice a box with the approximate amount of time that should be spent on each activity. This will serve as a guideline to you in order to conduct your warm-up in a time efficient manner.
1. Warm-up: Warming up and cooling down are a crucial part of a training program. The purpose of the warm-up section is to allow the athlete to prepare for activity. By warming up your muscles first, you greatly reduce the risk of injury.
A. Jog line to line (cone to cone): Elapsed Time: 0 – .5 minute
Purpose: Allows the athletes to slowly prepare themselves for the training session while minimizing the risk for injury. Educate athletes on good running technique; keep the hip/knee/ankle in straight alignment without the knee caving in or the feet whipping out to the side.
Instruction: Complete a slow jog from near to far sideline
B. Shuttle Run (side to side) Elapsed Time: .5 to 1 minute
Purpose: engage hip muscles (inner and outer thigh). This exercise will promote increased speed. Discourage inward caving of the knee joint. Instruction: Start is an athletic stance with a slight bend at the knee. Leading with the right foot, sidestep pushing off with the left foot (back leg). When you drive off with the back leg, be sure the hip/knee/ankle are in a straight line. Switch sides at half field.
C. Backward Running Elapsed Time: 1 – 1.5 minutes
Purpose: continued warm-up; engage hip extensors/hamstrings. Make sure the athlete lands on the toes. Be sure to watch for locking of the knee joint. As the athlete brings her foot back, make sure she maintains a slight bend to the knee.
Instruction: Run backwards from sideline to sideline. Land on your toes without snapping the knee back. Stay on your toes and keep the knees slightly bent at all times.
2. Stretching: It is important to incorporate a short warm-up prior to stretching. Never stretch a “cold muscle”. By doing the exercises outlined here, you can improve and maintain your range of motion, reduce stiffness in your joints, reduce post-exercise soreness, reduce the risk of injury and improve your overall mobility and performance e.
A. Calf stretch (30 seconds x 2 reps)
Purpose: stretch the calf muscle of the lower leg Instruction: Stand leading with your right leg. Bend forward at the waist and place your hands on the ground (V formation). Keep your right knee slightly bent and your left leg straight. Make sure your left foot is flat on the ground. Do not bounce during the stretch. Hold for 30 seconds. Switch sides and repeat.
B. Quadriceps stretch (30 seconds x 2 reps) Purpose: stretch the quadriceps muscle of the front of the thigh
Instruction: Place your left hand on your partner’s left shoulder. Reach back with your right hand and grab the front of your right ankle. Bring your heel to buttock. Make sure your knee is pointed down toward the ground. Keep your right leg close to your left. Don’t allow knee to wing out to the side and do not bend at the waist. Hold for 30 seconds and switch sides.
C. Figure Four Hamstring stretch (30 sec x 2 reps)
Purpose: To stretch the hamstring muscles of the back of the thigh. Instruction: Sit on the ground with your right leg extended out in front of you. Bend your left knee and rest the bottom of your foot on your right inner thigh. With a straight back, try to bring your chest toward your knee. Do not round your back. If you can, reach down toward your toes and pull them up toward your head. Do not bounce. Hold for 30 seconds and repeat with the other leg.
D. Inner Thigh Stretch (20 sec x 3 reps) Purpose: Elongate the muscles of the inner thigh (adductor group) Instruction: Remain seated on the ground. Spread your legs evenly apart. Slowly lower yourself to the center with a straight back. You want to feel a stretch in the inner thigh. Now reach toward the right with the right arm. Bring your left arm overhead the stretch over to the right. Hold the stretch and repeat on the opposite side.
Elapsed Time: 1.5 to 2.5 minutes
Elapsed Time: 2.5 to 3.5 minutes
Elapsed Time: 3.5 – 4.5 min
Elapsed Time: 4.5 – 5.5 min
E. Hip Flexor Stretch – (30 sec x 2 reps) Elapsed Time: 5.5- 6.5 min
Purpose: Elongate the hip flexors of the front of the thigh.
Instruction : Lunge forward leading with your right leg. Drop your left knee down to the ground. Placing your hands on top of your right thigh, lean forward with your hips. The hips should be square with your shoulders. If possible, maintain your balance and lift back for the left ankle and pull your heel to your buttocks. Hold for 30 seconds and repeat on the other side.
3. Strengthening: This portion of the program focuses on increasing leg strength. This will lead to increased leg strength and a more stable knee joint. Technique is everything; close attention must be paid to the performance of these exercises in order to avoid injury.
A. Walking Lunges (3 sets x 10 reps)
Purpose: Strengthen the thigh (quadriceps) muscle.
Instruction. Lunge forward leading with your right leg. Push off with your right leg and lunge forward with your left leg. Drop the back knee straight down. Make sure that your keep your front knee over your ankle. Control the motion and try to avoid you front knee from caving inward. If you can’t see your toes on your leading leg, you are doing the exercise incorrectly.
B. Russian Hamstring (3 sets x 10 reps) Purpose: Strengthen hamstrings muscles
Elapsed Time: 6.5 – 7.5 min
Elapsed Time: 7.5 –8.5 min
Instruction: Kneel on the ground with hands at your side. Have a partner hold firmly at your ankles. With a straight back, lead forward leading with your hips. Your knee, hip and shoulder should be in a straight line as you lean toward the ground. Do not bend at the waist. You should feel the hamstrings in the back of your thigh working. Repeat the exercise for 3 sets of 10, or a total of 30 reps.
C. Single Toe Raises (30 reps x 2 reps)
Purpose: This exercise strengthens the calf muscle and increases balance. Instruction: Stand up with your arms at your side. Bend the left knee up and maintain your balance. Slowly rise up on your right toes with good balance. You may hold your arms out ahead of you in order to help. Slowly repeat 30 times and switch to the other side. As you get stronger, you may need to add additional repetitions to this exercise to continue the strengthening effect of the exercise.
Elapsed Time: 8.5 – 9.5 min
4. Plyometrics – These exercises are explosive and help to build, power, strength and speed. The most important element when considering performance technique is the landing. It must be soft! When you land from a jump, you want to softly accept your weight on the balls of your feet slowly rolling back to the heel with a bent knee and a straight hip. These exercises are basic, however, it is critical to perform them correctly. Please take the time to ensure safe and correct completion of these exercises.
A. Lateral Hops over Cone (20 reps)
Purpose: Increase power/strength emphasizing neuromuscular control Instruction: Stand with a 6” cone to your left. Hop to the left over the cone softly landing on the balls of your feet land bending at the knee. Repeat this exercise hopping to the right.
B. Forward/Backward Hops over cone (20 reps)
Purpose: Increase power/strength emphasizing neuromuscular control Instruction: Hop over the cone/ball softly landing on the balls of your feet and bending at the knee. Now, hop backwards over the ball using the same landing technique. Be careful not to snap your knee back to straighten it. You want to maintain a slight bend to the knee. Repeat for 20 reps.
C. Single Leg hops over cone (20reps)
Purpose: Increase power/strength emphasizing neuromuscular control. Instruction: Hop over the cone/ball landing on the ball of your foot bending at the knee. Now, hop backwards over the ball using the same landing technique. Be careful not to snap your knee back to straighten it. You want to maintain a slight bend to the knee. Repeat for 20 reps. Now, stand on the left leg and repeat the exercise. Increase the number of repetitions as needed.

Elapsed Time 14 – 15 min
6. Alternative Exercises – Warm Down and Cool Down
We all know how imperative a cool down is. Please don’t skip it. It allows the muscles that have been working hard throughout the training session to elongate and deters the onset of muscle soreness. Please emphasize the importance of adequate fluid intake (optimally water). Athletes should have a water bottle by their side during the cool down. The cool down should take approximately 10 minutes. It should begin with a slow jog to allow the heart rate to come down before stretching. This should be followed by some light strength training exercises. We are recommending two strengthening exercises (see below). Finally, stretch the hamstrings, calves, inner thigh, quadriceps, and low back (all of these are explained in the protocol). In addition to those basic stretches, we are offering some additional stretches to target 3 muscle groups that are often forgotten.
A. Bridging with Alternating Hip Flexion (30reps)
Purpose: Strengthen outer hip muscles (Hip abductors, flexors) and buttocks
Instruction: Lie on the ground with your knees bent with feet on the ground. Raise your buttocks up off the ground and squeeze. Now, lift your right foot off the ground and make sure that your right hip does not dip down. Lower your right foot and now lift your left foot making sure your left hip does not dip down. Repeat 30 times on each side. As you get stronger, you will place your feet on top of a ball and repeat the exercise.
B. Abdominal Crunches (30repsx2reps)
Purpose: Strengthen n the abdominals (rectus abdominus, obliques)
Instruction: Lie on the ground with you knees bent. Place your hands behind your head with your elbows out wide. Support your neck lightly with your fingers. Take a deep breath in and slowly contract your abdominal muscles as you exhale. Repeat 30 times. Drop your legs off to the right side. Slowly crunch up with your elbows out wide. You should feel your oblique muscles working on the side of your waist. Repeat 30 times and switch to the other side.
C. Single and Double Knee to Chest (supine) (30 sec x 2 reps) Purpose: Elongate the low back muscles Instruction: Lie on your back. Bring your right knee toward your chest and hug firmly. Keep your left leg out straight in front of you. You should feel a stretch along your low back and into your buttocks. Hold the stretch for 30 seconds and switch sides. Now bring both knees to chest. If you feel any pain in the low back, discontinue the stretch and inform your coach/trainer.
