Preparation and Maintenance of the Foundation
It is important to remember that all muscle
groups must be evenly developed and strengthened for any technique,
completely natural, or imposed, to work effectively and reduce the
likelihood of injury through running. As one muscle contracts and
shortens, the opposing muscle group must also elongate in controlled
fashion to generate a planned and even movement. In order for muscles
to work in concert in pure and powerful planes, their base of support
must be firmly stabilized and balanced. Therefore it is crucial
to insure a strong core prior to moving forward into plyometric
training. In reality, most may take interest in learning and applying
new techniques, but a vast majority within weeks will return to
what comes natural. What will be left with be your enjoyment for
running, and the routine that you’ve created to support it.
This routine should include exercises and drills that are believed
to make you not only more efficient on the run, but also a healthier
individual.
Core Training
The following program has been taken from:
“Core Stabilization Training for Middle and Long-Distance
Runners” by Michael Fredericson, Tammara Moore
Fundamental Lumbo-Pelvic
Stability
Frequency: 3 sessions per week
Sets: start with 1 – 2 sets of 15, progress to 3 sets of 20
Supine Bent-Knee
Raises
Purpose: To recruit deep abdominal muscles for lumbopelvic control.
Process: Lying on back, knees bent, feet flat. Alternately raise
feet to opposing knee height while insuring that pelvis remains
straight and lumbar curvature is kept in tact.
Progression: Add extending legs and lowering to the ground, and/or
raising alternate arm overhead.
Quadruped with Alternate
Arm/Leg Raises
Purpose: To engage the deep transverse spine stabilizer and extensor
of the lumbar spine.
Process: On “all fours”, raise right arm and left leg
into line while maintaining lumbar curvature and without rocking
the pelvis or spine. Alternate arms/legs.
Bridging
Purpose: Core stabilizing and gluteal strengthening exercise.
Process: Lying on back knees bent, feet flat, arms at sides, athlete
will contract abdominals and squeeze gluts followed by a lifting
of the hips off the ground until straight line is formed with hips,
knees and shoulders. Maintain lumbar curvature and insure no rotation
occurs in the pelvis. Hold for 10 seconds and then lower butt back
to floor.
Progression: In the lifted position, lift one foot off of the ground
by extending leg, and/or complete with arms across chest.
Prone Plank
Purpose: Static core stability exercise.
Process: Forearms resting on mat, elbows bent to 90 degrees, and
toes resting on mat. Contract gluteals while maintaining spine curvature
and head parallel to the floor, holding for 20 seconds and progressing
to 1, 2, and 3 minutes with no compensatory lumbar flattening lordosis.
Progression: Alternate lifting each leg off the mat for 5 seconds.
Side Plank
Purpose: Static core stability exercise, trains quadratus lumborum.
Process: Lying on right side with right arm extended less than perpendicularly
into mat, bent at elbow with forearm resting on mat. Raise pelvis
from the floor and hold in straight “plank” position
with minimal hip sag, holding for 20 seconds, working up to 1, 2,
and 3 minute intervals.
Progression: Raising top foot to challenge core and gluts.
Advanced Lumbo-Pelvic
Stability
2 sessions per week
1 – 2 sets of 10 – 15 repetitions
Seated Marching
on Physioball
Process: Sitting upright on physioball, spine curvature maintained,
feet hip width apart. Raise alternating feet to opposing shins while
contracting core and maintaining pelvic alignment
Progression: Addition of opposite arm lifts.
Spinal Flexion on
Physioball
Process: Lying on back with physioball positioned underneath spine,
knees bent slightly to position feet flat for stability, arms overhead
with elbows bent and hands resting behind ears. Brace abdominals
and raise head, neck and thoracic spine up in crunch fashion being
mindful of moving thoracic spine, neck and head in straight fixed
line. Visualize touching bottom of ribs to pelvis.
Progression: Performing while holding medicine ball with arms extended
overhead.
Alternate Leg Bridge
with Shoulders on Ball
Process: Start seated on physioball and walking feet slowly forward
while slowly leaning back until shoulders, neck and head rest on
ball, knees bent to 90 degrees with feet flat on ground. Abdominals
braced, foot raised as knee is extended. Stability should be maintained
with no pelvic tilting with position held for 10 seconds in alternated
legs.
Progression: Adding arms lifted into the air or out to the sides.
Leg Curls on Physioball
Purpose: Recruit both actions of hamstrings – hip extension
and knee flexion – while maintaining dynamic core stability.
Process: Lying on back on floor, place both shoeless feet on physioball,
with arms at sides on floor for balance, raising the hips off the
ground until the knees, hips, and shoulders create a straight line.
Push the ball forward while maintaining the bridge and stability
of the pelvis.
Progression: Progress to single-leg.
Abdominal Rollout
Process: Kneeling behind physioball with both elbows/forearms on
ball, brace abdominals and lower back with spine curvature maintained,
rolling the ball away until a straight line is formed from the shoulder
to the hips, pulling back, then rolling out again with movement
at shoulders and not in the back.
Progression: Straighten body fully until up on toes with straight
line from the back of the head to the knees, again moving ball to/fro.
Squat Ball Thrust
Process: In push-up position with lower legs resting on ball, bracing
abdominals with lower back and shoulder blades maintained, use abdominal
contraction to move ball forward onto toes with knees bent.
Progression: Single leg/toes on the ball at a time.
Development of Balance
and Motor Control
Forward/Backward
Rocking
Process: Standing with body fully aligned on rocker board or dynadisc,
shifting forward and backward for several minutes while maintaining
alignment from head to toes and spinal curvature maintained, arms
at rest at sides.
Progression: Progress to knees slightly flexed with alternating
quick/slow back/forth movements.
Single-Leg Balance
– 3 Planes
Process: Initiating a stepping forward and backward motion while
on rocker board or dynadisc, maintaining alignment.
Progression: Progressing to run-style motion with opposing arm and
leg swing phases while insuring no overflow or unstable accessory
movements through the pelvis or spine.
Weight Transfers
with Proper Alignment
Process: Leaning forward into fall with forward catching leg landing
on rocker board or dynadisc.
Functional Movement
Training
Single-Leg Balance
with Hip Flexion
Purpose: Provides a functional movement pattern that is similar
to running, increasing the stability of the lower abdominal muscles
while using forward motion at the hip.
Process: While balancing on one leg, initiate running motion in
both leg and opposing arm while insuring abdominal brace and spinal
curvature with no pelvic rotation.
Progression: Attach a pulley or resistive band to the ankle to challenge
hip flexors.
Multi-Directional
Lunges
Process: Perform a step into a forward lunge, stepping forward with
front knee bent to 90 degrees, patella in line with and no further
forward than ankle, and spinal curvature maintained
Progression: Perform in multiple directions and/or onto a dynadisc.
Standing Pulley
or Medicine Ball Rotation
Purpose: Dynamic challenge to the core with rotational movement
pattern while abdominals braced and rib cage and pelvis locked as
one to minimize torsional stress to spine.
Process: Standing with feet shoulder-width apart, knees slightly
bent, abdomen braced and spinal curvature maintained. Grasp medicine
ball with arms extended and rotate the trunk by activating the abdominal
obliques and spinal rotators while critically maintaining a stable
pelvis.
Progression: Addition of diagonal motions.
Forward Lunge with
Medicine Ball with Trunk Rotation
Purpose: Challenge core muscles with appropriate weight shift, balance,
and control on one leg.
Process: Using a 30 meter range, standing upright, holding medicine
ball with arms outstretched and perpendicular to body. Step forward
with medicine ball in front of chest, completing lunge motion and
bringing ball across chest to same side of body toward the same
side as the forward leg, then returning the midline for the next/opposing
step. The patella should not move in front of the ankle and should
be aligned with second toe.
Standing Reverse
Wood-Chop with Medicine Ball
Purpose: Combine dynamic upper and lower chain movement demanding
pelvic stability.
Process: Stand with medicine ball in hands with arms extended, feet
shoulder-width apart, move the ball from a lower position at the
hip, across the body to the opposite shoulder. Reverse in starting
at opposite hip and ending overhead at opposite shoulder.
Progression: Progress to performing while standing on one leg.
A potential recommended sequence for use
of core training exercises would start with the use of Mobility
Restoration and Fundamental Cores Stability Exercises in the Summer
or Fall Base Training Phase. Advanced Core Stability and Functional
Movement Training may assumed with the winter specific preparation
phase, and Plyometrics during the Spring/Summer Competition Phase.
Strength Training
Strength training goals may include the
recruitment of a greater amount of muscle fibers then when running
distance events, to minimize ground contact time, to improve posture
and as a by product, improve running mechanics. Strength training
will include the use of body weight, and magnified body weight,
during drills. Adding maximal/explosive strength training use other
mediums should require handling 85 to 90% of one-repetition maximum
weight for 3 to 5 sets of 5 repetitions.
Plyometrics
Plyometrics focus on enhancing the speed
component of muscle activation through providing a eccentric (lengthening)
contraction to a muscle immediately prior to a forceful concentric
(shortening) contraction.
Neither explosive strength training nor
plyometrics play a role in developing VO2 max (maximal amount of
oxygen transported in the blood) or lactate threshold (level of
lactic acid tolerated or accumulated for use in the blood). Substituting
a percentage of running workouts with both of these methods has
been found to improve performance more than running alone despite
having no effect on V02 and lactate threshold. It is believed that
these exercises adapt the nervous system to call forth a greater
number of muscle fibers for stronger, quicker and more powerful
muscles without added bulk. The result is more economical and efficient
running biomechanics and capacity. Explosive strength and plyometric
training should coincide with the speed phase or period of training
as opposed to during aerobic endurance phases.

A. Single leg hops: 1) On one leg, hop
up and down; 2) hop forward and back; 3) hop side-to-side.
B. Bleacher hops: Standing at the bottom of the bleacher steps on
one leg, hop up the steps. Walk back down and hop up again on the
other leg.
C. Double leg bound: From a squat position with both legs, jump
forward as far as you can.
D. Alternate leg bound: in an exaggerated running motion, bound
(which looks like a combination of running and jumping) forward
from one leg to the other.
E. Squat jumps: With hands on hips in a squat position, jump straight
up as high as you can. Upon landing, lower back into a squat position
in one smooth motion, and immediately jump up again. Bending the
knees upon landing, tour forward knee should not migrate past the
toes and the back knee should fall within 1 inch of the ground.
The upper body should be maintained with an erect posture.
a. Can insert split squat jumps wherein once airborne the legs are
quickly and smoothly switched front <->back.
F. Depth jumps: From a standing position on a one-foot tall box,
jump onto the ground and land in a squat position. From this squat
position, jump straight up as high as you can.
G. Box jumps: From the ground, jump with two feet onto a box about
one foot high, and then immediately jump into the air and back down
to the ground. As you get experienced with the exercise, try jumping
with one foot at a time.
* Sample Plyometric Training Program taken
from “An in-depth look at running economy”, Track Coach,
Winter 2008, by J. Karp.
Explosive arm movements should be
used in concert with leg movements in all exercises to aid with
height, distance, and explosion. Additional upper body power exercises
can be added the mix including the close grip snatch and one are
snatch. Correlations have been made between improvements in the
standing long jump, 2, 3, and 5-hop jumping with improved running
performance and as a gauge of adaptation to training loads and planning.
Plyometric exercises may prove not only vital foundations to appropriate
injury-free running biomechanics, but also can be used to measure
training effect and guide training programs.
