Energy System Training: Sprints vs. Middle & Long Distances
Feedback is definitely a great tool for refining the communicative processes. After some great feedback on my last post concerning Energy System Training guidelines, I have to NOW clarify that the recovery guidelines (except for the short 0-6 second maximum sprints) were based on lower percentages of maximum speeds as used in Middle and Long Distance Training reps.
Since most readers of this Blog have read my book (or, at least have a copy), suffice it to say that the Energy System Charts with volumes, velocities and rest guidelines that appear in it, are for Sprint Training.
Once Sprinters/Hurdlers leave Extensive Tempo Training (75% or < Intensity), they move to Intensive Tempo (76% to 94% Intensity), Speed Endurance (7”-15” at 95-100% Intensity), Specific Endurance (Specific End. I =15”-40” and Specific End. II = 40-60” at 95-100% Intensity) and Special Endurance (Split Runs lasting over 7 seconds each).
Middle and Long Distance Training involves repetition speeds that are based on Onset of Blood Lactate, Lactate Threshold and MaxVo2 Values. When they do “real” speed work, such as Speed Endurance work like 4 x 150 meters at maximum effort or Flying 60’s at Maximum Velocity, they need much more rest than when doing 150-200 reps at 1500 pace.
Recoveries used for the Sprint Training energy system zones of Intensive Tempo, Speed Endurance, Special Endurance I and II, and Specific Endurance are as follows:
SPEED ENDURANCE (7-15” @ 95-100%) = Full (1-2 min/second of activity).
SPECIAL ENDURANCE I & II (15”-40+” @ 95-100%) = Full (0.5-1.5min per second of activity).
SPECIFIC ENDURANCE (Split runs over 7” each @ 95-100%) = Incomplete
It is important to note that Specific Endurance involves Split runs with incomplete rest between the two runs. An example would be sprinting a 200 at race speed, 45” -1’ rest then sprint 100 meters at race speed. This can be repeated 1-2 time with high level athletes with FULL rest between each Split run.
Another term that needs to be clarified is that of intensity. Sprint training intensity can be evaluated in relation to “absolute intensity” and “relative intensity”.
“Absolute intensity” involves intensity in relation to absolute human performance. This would involve maximum velocities reached for 100 meters “always” being at a higher “absolute intensity” level than the intensities reached for 400 meters. Velocities in the 100 meter race will always be higher than those achieved in the 400 meters, even though the 400 is a much more demanding race.
“Relative Intensity” relates to the individual’s personal best or “potential” performance over any distance. When using “relative intensity”, coaches design workouts where 100% Intensity is relative to the individual athlete’s personal best or “potential” best in the various race distances.
Determining individual “relative intensities” can be done by dividing the athlete’s 100% or potential performance time for an event by the percentage you want them to run a specific distance. For example, an athlete with a 200 meter best of 22.00 would run 200 reps at 90% of 22.00(24.44), or 80% of 22.00(27.50) if the plan was for Intensive Tempo 200’s. If the plan called for Special Endurance (95-100%), the target time for the 200 or 2 x 200 w/Full Rest, would be 22.0-23.2 seconds! Thus, the intensity of the workout is dictated by the type of training desired for the specific phase of the Training Year AND each athlete’s personal best times.
While on the subject of Energy System Training, I feel it is important to cover some of the adaptations that take place in Short Sprint (0-10 seconds) Work. Using workouts comprised of 20m to 100m (starting with 20m and working up to 30, 40, 50, 60 and so on) sprints 2-3 times per week can result in 25-50% increases in ATP/CP stores.
Studies also show that 6-8 weeks of short sprint training result in an increase in enzyme activity allowing for the break down and reconstruction of ATP. This enhanced enzyme activity allows for ATP to be broken down faster and energy released quicker in addition to increasing levels of both ATP and CP which are the energy sources of maximum speed/power efforts lasting less than 7”.
The next post will struggle to explain Lactic Acid and Lactate in relation to developing Speed Endurance and Special Endurance in Sprinters and also why improving Onset of Lactate or V4 values for Middle Distance and Distance Runners should be one of the emphases in designing Distance Training plans.

Energy System Training Methods: What do we want to accomplish?
For instance, sprinters who race 100 and 200 require a greater emphasis on training the Phosphagen (ATP-CP) energy system whereas the 400 meter sprinter would require a greater emphasis on the Glycolytic (especially Fast Glycolysis-Phosphagen) energy system. However, it is extremely important that both employ percentages of training the Phosphagen (ATP-CP) AND Glycolytic (Fast Glycolytic) systems.
Taking this up the event ladder, 800 meter runners would want to invest some training time in both Phosphagen and Fast Glycolytic areas but emphasize Fast Glycolytic + Oxidative systems training.
1500 runners would emphasize more Fast Glycolytic + Oxidative training while mixing in small amounts of Fast Glycolysis work and medium to high amounts of Oxidative work.
So, how do coaches without a Exercise Physiology background wrap their heads around applying the proper Energy System Training for their individual athletes?
Since Time and Intensity determine what energy system will be the primary energy source, it would be helpful to list the Systems with the specific durations and intensities of efforts unique to each Energy System.
Five Energy System Training Zones are shown below and linked to the intensity and time of efforts relative to repetitions used in each Energy System Training Zone.
1 Phosphagen System 0-6” (sec) Maximum Speed/Power
2 Phosphagen+F.Glycolosis 6-30”(sec) 90- 95% Mx Speed/Power
3 Fast Glycolosis 30”>2’ (min) 75-90% Mx Speed/Power
4 F.Glycolosis+Oxidative 2’-3’ 30-75% Mx Speed/Power
5 Oxidative > 3’ 20-35% Mx Speed/Power
Using the above as a means to determine workouts that would target each specific energy system for training can be a useful tool if used with the proper recovery times. Proper recovery times for each training zone are shown below.
LISTED AFTER EACH ENERGY SYSTEM IS THE AMOUNT OF TIME UTLIZED IN THE REPETITION, FOLLOWED BY THE WORK TO REST RATIO.
1 Phosphagen (efforts of 0>10 seconds) 1:12---1:20
2 Phos.+F.Glycolysis 15”-30” 1:3---1:5
3 F.Glycolysis 30”-60” 1:4---1:6
4 F.Glycolysis+Oxid. 60”>3’ 1:3---1:4
5 Oxidative >3’ 1:1-1:3
Without getting into the long distance training areas of Max Vo2 percentages, LT (Lactate Threshold) or OBL/V4 (Onset of Blood Lactate), it would suffice to say that from 100 to 800 meters there needs to be a certain percentage of training in the first Four Energy System Zones that occurs throughout the training year.
Obviously, the percentages of training in each zone would be based on event, time of year, training age of the athlete and specific body type of the athlete.
It is the attention paid to all these types of details that allows coaches to become true artists in drawing a training plan for their athletes. In the next post I will try and get to the sensitive area of explaining the adaptations that take place when proper training in the first three zones is applied and the what role Lactic Acid really plays in the training adaptation process.

Using Test Results to Design Training Plans
Strength Tests showed the following improvements in the Squat Maximums: 21.3%, 20.4%, 9.6%, 13.8%, 18%, 37%, 9.2%, 13.6%, 20.4% 29.3% and 17.5% for the 11 athletes who tested in all 3 Mesocycles. It should be noted that the three lowest percentage of increase values belonged to athletes who began in the program last Spring and lifted over the Summer. Deadlift improvements were as follows: 64.2%, 53.7%, NC, 8.9%, 19.9%, 28.9% 29.7%, 26.1%, 15.4%, 15.6% and 25.3%. Deadlift improvements seemed to be much greater than Squat improvements when looking only at the numbers but it should be noted that most athletes had no experience in executing the Clean Deadlift and emphasis on technique in the first Two Mesocycles yeilded impressive results. As with the Squat numbers, the lowest percentages of improvement were those of athletes who had been lifting over the Summer and already established good lifting technique.
Power/Speed and Special Endurance Testing showed maintenance of Maximum Velocity (as measured by flying 30 and 20m tests) with big gains in Special Endurance (as measured by 325m T.T.). Improvements ranged from 4.13 seconds (from Mesocycle One to Mesocycle Three) to 0.11 seconds with an average improvement of 2.11 seconds. The 0.11 second improvement represents an athlete who missed the all of the Second Mesocycle of training.
The Maximum Velocity and Special Endurance Tests validated the emphasis on Endurance Training and lower emphasis on Maximum Velocity.
In addition, the Multi-Jump and Multi-Throw training volume increases and attention to technique resulted in big increases in 5Double Leg Bound, Overhead Backwards MB Toss, Between the Legs Forward MB Toss Tests.
Care must be taken to look at testing results in relation to the athletes tested. In many cases there were special circumstances that dictated lower than expected improvements. Some athletes had recent illnesses or absences while some athletes are present on only 3 of the 4 days per week of training. Knowing the circumstances helps the coach to better asses what should be the areas of emphasis for the next Mesocycle of training.
Testing is not easy to implement but certainly plays a major role in helping coaches indentify areas of concern to target for the next training block. Also, the type of athletes plays an even larger role. For example, most of the athletes I work with are more 400/400h and Jumper types and five of them are Throwers. It is necessary to individualize drills, exercises, etc. that target explosive strength, speed, elastic strength, power and endurance according to the specific events of the athletes.
In the next post I will explain background information on Specific Energy System training methods to employ for sprinters of all types.

Fall Training Test Results for Special Endurance
325m T.T.
Wk.4 Test Wk.8 Test
46.81 45.40
46.33 44.43
45.28 DNT
43.46 41.43
Sick 47.07
42.90 41.43
44.05 42.54
44.61 Knee Inj.(Basketball)
The results for those who did both tests showed improvements of 1.41, 1.90, 2.03, 1.47 and 1.51 seconds for the 325 Time Trial #2.
Weeks 9-12 will involve a gradual shift from Extensive Tempo at 75-80% to Intensive Tempo at 80-90% with increases in Work to Rest Ratios. For example, the Mesocycle Two /Tuesday type workout of 2x4x200 at 75% w/1.5’ & 3’ would gradually evolve to 4 x 200 @ 85% w/ 4’-5’. Short Sprint work on MW would progress from 20-40m reps to 40- 60m reps while Thursday Endurance work would progress to 300-350m reps at 80-85% of 400m goal times w/1:3-1:5 work rest ratios.
The emphasis of the program is utilizing the Short to Long Sprint work while integrating both short and long Extensive Tempo to allow for energy system training between 20” and 80” at speeds between 75% of 200 goal times and 75-80% of 400 goal times.
THE ROLE OF STRENGTH/POWER TRAINING IN SPRINT ACCELERATION
THE ROLE OF STRENGTH/POWER TRAINING
IN SPRINT ACCELERATION: PART ONE
In order for successful acceleration mechanics to be performed, the sprinter must execute a technically efficient and powerful start, so as to allow for the optimal body lean and posture necessary for a sound entry into the acceleration phase.
The role of Strength/Power Training in all phases of the sprint race cannot be underestimated. Any discussion of Acceleration Mechanics specific to teaching sprinters to properly execute the Acceleration Phase of the sprint race must take into account the relationship between proper mechanics and the strength/power required to do so.
In “The Mechanics of Sprinting and Hurdling” (Dr. R. Mann, self published, 2007), Dr. Ralph Mann points out several elemental relationships between strength and the ability to be more mechanically efficient or productive in the various areas/phases of the sprint race.
Dr. Mann cites three specific examples of this Strength/Mechanical Efficiency relationship affecting a proper Sprint Start and the ability to perform a successful acceleration phase.
1) Greater strength allows for the athlete to produce greater horizontal forces in the Start (pg. 52).
2) Greater horizontal force produced at the Start allows for the sprinter to stay lower at the Start (pg.52).
3) Success in the short sprint race is determined by the ability of the sprinter to generate great amounts of explosive strength at the proper time. (pg. 91).
Mann’s analysis of sprinters found that weaker athletes tend to “pop up” during the Start because lesser amounts of horizontal force produced at the Start creates the need for the athlete to move the center of gravity vertically in order to maintain balance.
Given the need for the “falling or leaning” body position to properly execute a successful acceleration phase, block start mechanics must be incorporated into the drills used in teaching proper acceleration mechanics.
Glen Mills, coach of Usain Bolt and many world-class sprinters, alluded to the role of strength in the acceleration phase (termed Drive by many coaches) in an interview where he echoed the statements by Dr. Mann; “…the athlete has to stay in the crouch position while developing maximum power. If the athlete does not have the strength to carry the drive phase long enough then it has to be aborted so he can go into the transition earlier.”
Incorporation of relevant MAXIMUM STRENGTH (also termed Static), EXPLOSIVE STRENGTH (also termed Dynamic) AND ELASTIC STRENGTH development exercises into the overall sprint-training program cannot be argued in view of the proven interdependence between Strength and the ability to optimally perform the proven principals of Sprint Mechanics in all phases of the short sprint race.
Since Part 4 of this Acceleration Article will deal with Elastic Strength (or Plyometric Training), this section will focus on Maximum Strength and Explosive Strength Training exercises proven to be relevant to proper execution of Start, Acceleration and Maximum Velocity phases of the sprint race.
Both Maximum Strength and Explosive Strength exercises must be used in order to address both Intramuscular and Intermuscular coordination factors. Through the proper mixing of Maximum and Explosive Strength exercises, Recruitment, Rate Coding and Synchronization can be optimally developed through use of exercises that coordinate the amount of force, speed of movement and precision of movement patterns applicable to effective sprint mechanics. Use of exercises that cover the entire Force-Velocity Curve, with an emphasis on moving the curve to left over time, cannot be done with a proper mix of Maximum, Explosive and Elastic Strength exercises.
There seems to be a considerable amount of confusion among coaches about the need for Maximum Strength exercises to be included with Explosive Strength exercises in the training of sprinters. The idea that lifting heavy loads in a relatively slow manner is of no use to the high speed movements of sprinters needs to revisited in light of the specific research findings provided in “Strength and Power in Sport”, (P.V. Komi, IOC Medical Commission, 1992). Some of these specific findings are listed below.
1) High threshold Fast Twitch Glycolytic (FTb) Muscle Units are NOT recruited UNTIL force exceeds 90% of Maximum Strength (pg. 250).
2) Training with high velocity movements increases high velocity strength (pg. 263).
3) The load to be overcome and the movement time are the main factors in developing Rate of Force Development. If the load to be overcome is light, IRFD (Initial Rate of Force Development) predominates. If the load to be overcome is high, then MRFD (Maximum Rate of Force Dev.) predominates. For movements with a duration of 250ms or less (sprinting), BOTH IRFD and MRFD are the main factors (pg. 381).
4) Maximal Strength and Power are not distinct entities. Maximum Strength is the basic quality that influences power performance (pg. 383).
5) Improvements in Power have been shown to result from high intensity strength training, jump training under increased stretching loads and movement specific exercises requiring muscular coordination training (pg. 384, 385).
6) The use of training methods involving, maximal and near maximal contractions, cause a remarkable increase in RFD accompanied by an increase in movement speed (pg. 392).
7) RFD directed training should take precedence in the Preparation Phases but not be completely eliminated at any time of the training year (pg. 392).
Understanding the neural adaptations to the various strength training methods will allow for an intelligent selection of specific exercises and their proper integration into the overall training plan of each individual.
Strength/Power Training Plans must address the training age of the individuals within the sprint group. Beginning/Novice sprinters require different considerations than Intermediate and Advanced athletes. For example, research shows that Maximum Strength increases will also lead to increases in Power and the ability to generate force at fast speeds, especially in less experienced athletes. Training plans for Beginning/Novice athletes should contain more emphasis on Maximum Strength development and the teaching of proper lifting mechanics.
