Few sports require the
degree of aerobic and anaerobic fitness, combined with the ability to withstand sometimes
violent collisions, needed to compete at soccers highest levels. Soccer players at
the club and recreational levels also must maintain top conditioning to compete
successfully. "You have to build not only a very strong aerobic base, but you have to
have an anaerobic base and an anaerobic endurance base," says Dr. Preston Wolin, head
team physician for Major League Soccers Chicago Fire. "Not only are you
constantly running, but you have to accelerate for extended periods of time. To be able to
do that, you have to be extremely well-trained."
Soccer is a team sport that is won or lost based on how well a team can
work together. Team strategy, execution and spirit are critical to success in the sport.
However, a team is made up of unique individuals all having different conditioning
requirements and abilities. Customizing a program to maximize each individuals
capabilities provides the best approach to building the most successful team.
One-size-fits-all conditioning programs typically provide only mediocre results since they
tend to over-train some athletes and under-train the others.
A conditioning program based on common goals that are focused on each
athletes primary weaknesses provides the best results. This study was conducted to
determine the most effective and efficient way for a coach to adapt his/her current
conditioning practices that would provide his team the best results. An eight week study
was conducted to develop and test an elite level soccer training program that can be used
by high school and club team coaches throughout the United States. The primary goals of
the program were to improve overall performance and minimize the chances of injuries.
The pilot program focused on:
- improvement in body control and flexibility
- improvement in overall body strength especially as it relates to muscular balance
- increased in mental concentration
- increased endurance and energy reserves
The study participants included 14 high school soccer players that were
at the varsity level and/or played select high school club soccer.
Baseline Assessments
Each athlete participated in a baseline assessment that included an
aerobic endurance test (sub-V02max, walking test on the treadmill), upper body and lower
body strength test, flexibility test and leg balance test. A sport psychological and
nutritional test were also administered during the eight weeks.
The baseline assessment data was compared to normative data collected
for the Australian National U17 Soccer Team. Each athlete was compared to the team average
and the goal established based on the normative data.
Program Implementation
The following program components were administered during the 8 weeks:
- Aerobic conditioning
using heart rate monitors and Technogym equipment
(treadmill and elliptical trainer), interval training was administered to improve the
cardiovascular endurance for each athlete between 2-3 days per week.
- Flexibility and muscular balancing
a rigorous Pilates and core conditioning
training program was administered to improve overall flexibility and muscular balance one
day per week.
- Strength/Power
focused strength training was provided with a focus on
muscular development and power two days per week. The program was based on the research
conducted by Technogym with the Italian Soccer Team.
- Sports nutrition
dietary habits were reviewed and discussed, based on a one
week nutrition log, to determine optimal levels and areas for improvement.
- Sports psychology
based on the psychological assessment each athletes
profiles were evaluated for implementing a customized guided imagery and visualization
program to improve overall game performance, skill consistency and concentration.
Each area was monitored and tracked using Vitals Proactive Health
and Sports Enhancement Database. All workout data was recorded using the Technogym
Training System and Smartkey technology.
Post Testing
At the end of the 8 weeks each athlete that completed the program was
re-assessed using the same process as the base-line assessment. In addition, a post
program survey was conducted to evaluate each participants expectations and satisfaction
of the program and how they felt the conditioning program improved their soccer playing
ability.
Results
Conditioning
The soccer conditioning program showed a significant improvement in
aerobic endurance (14.5%) and flexibility (34.2%) with each improving over 30%. The
overall team ranking in aerobic endurance improved to that of the level of the Australian
U17 National Team. The flexibility score improved to 20.1 which is still 2 points short of
the Australian U17 National Team average.
Upper body strength improved on average by 9.9%. Lower body strength
based on the leg extension test (quadriceps) improved on average by over 33% while the leg
curl (hamstrings) only improved by 8%. The leg balance ratio (hamstring
strength/quadriceps strength) went from 76% to 63%.

Nutritional
Results The nutrition analysis revealed that the majority of
athletes were not eating proper diets to improve energy reserves and performance. In
almost all cases, comparing the diet with that of recommended allowances showed
deficiencies in fruits, vegetables and complex carbohydrates. In most cases, athletes were
not consuming enough calories recommended for their body weight and activity levels. In
addition, most consumed less protein than the recommended amount for their weight.
Through making modifications to their diet to include enough complex
carbohydrates and nutrients these athletes can improve their overall performance by 186%.
Psychological Results
The psychological test was administered at the beginning of the
program. The tests were developed, reviewed and consolidated by Dr. John Chang. Through
analysis of the test Dr. Chang reviewed team level information with the Coach. Only
athletes that chose to work one-on-one with Dr. Chang participated in this part of
the program.
The primary areas analyzed included concentration, coachability and
pre-game anxiety. Visualization techniques were discussed to reduce pre-game anxiety. No
visualization suggestions were provided during this study. A number of the participants
participated in a muscular relaxation exercise.
Survey Results
Each athlete completed a subjective questionnaire relating to the
effectiveness of the program. The average score received on a 1-10 scale (10=outstanding)
was a 9.5. The part of the program that was liked the best was the reformer workouts.
Overall improvement to their performance on the field was rated on average as a score of
8.2.
Conclusions
Concentrated effort in aerobic endurance training and flexibility has a
significant positive effect on overall conditioning, improving both overall performance
and reducing chances of injury. Each athletes aerobic endurance score (VO2max)
increased to conclude that even with the extensive soccer practices and matches played by
the athletes tested, each showed a positive correlation between improved aerobic
performance and concentrated aerobic conditioning within predefined targeted heart rate
zones.
Flexibility improved which is directly related to reduced injury.
Pilates reformers provided for the significant increase in flexibility and overall
muscular balance and core stabilization.
The exercises chosen for lower body work included squats, lunges, low
pulley hip flexion-4 ways, and squat jumps. These exercises improved quadriceps strength
over 33% , however, only improved hamstring strength by 8% thereby causing a greater
imbalance than in the originally tested. This showed a strong indication toward more
concentrated hamstring work required to better balance the muscular strength in the legs.
The study is a basis for establishing a good case that soccer practice
and games are not enough to optimize an athletes overall condition. Individual
fitness levels play a big role in the athletes ability to improve their overall
performance. Therefore, cookie-cutter programs will not work in maximizing each
athletes performance level. Individual programs that are customized to meet the
requirements of each athlete are critical to success. In addition, educating in the proper
areas of nutrition and sports psychology can have a big impact on performance.

- Study released by Berstrum, et.al. revealed a diet including high carbs (204 mmol/kg)
allowed an athlete to remain at 75% of their VO2max for over 170 mins. compared to a low
