Explosive Training

The following article is published here with the permission of the author, Ken Mannie, Head Strength & Conditioning Coach at Michigan State University

The subject of explosive weight training is one that has been in the center of a maelstrom among strength and conditioning practitioners for quite some time. Many individuals and some associations advocate the use of so-called explosive weight training movements, which purportedly offer trainees a distinct advantage in speed and power development over those who choose to incorporate more controlled movements.

It is also suggested by some that explosive weight training movements prepare the body for the exorbitant, potentially traumatic forces of competition more so than other strength training techniques.

For the purpose of this article, only the explosive lifts will be discussed. These include-but are not solely restricted to-the Olympic lifts (i.e., the snatch and clean and jerk), power clean, speed-squats, push jerks and any variations of these movements. Basically any movement performed in a rapid, jerky manner where momentum plays a key role in the execution and or completion of the movement would be included.

The intent of this article is three-fold:

  1. to elucidate the fact that ballistic weight training movements carry with them the highest injury potential of any resistance exercises performed in the weight room setting;
  2. to dispute the erroneous notion that there exists a definitive physiological or biomechanical mechanism by which ballistic weight training movements result in a distinct and irrefutable advantage over controlled, high tension resistance exercises in producing and/or enhancing speed, power or athletic skill development; and
  3. to offer safer more efficient and more productive training alternatives.

The Risk Factor

It is a an accepted premise that all types of resistance modes and/or ideologies will have a certain degree of risk attached to them. This is why instruction and supervision are paramount in resistance training programs, regardless of the lifting movements being performed. There will also be contradictions regarding exercise prescription in isolated cases due to past injuries, structural abnormalities and other physical impediments. As with any physical activity, there exists an assumption of risk with strength training and this is why the participants must be well-schooled regarding lifting/spotting techniques and the myriad of safety guidelines which are of utmost importance in the weight room setting. With judicious care, the majority of the environmental risks associated with the weight room can be effectively controlled.

However, the aforementioned ballistic lifts are immersed in inherent dangers even when supervision and correct techniques are evident. There exists a prepoderance of evidence (4,5,8,9,10,14,17,21,22,23,29,33,34,38) indicating that so-called explosive weight training movements carry a high risk of injury, both acutely and cumulatively, to muscle tissue, fascia, connective tissue and bony structures. Westcott (38) states that the acceleration and deceleration forces placed on involved tendons, ligaments, muscle fascia and bone create both initial and terminal stresses on these structures which are likely to produce training injuries.

Several of the lifts being examined here – primarily the Olympic lifts, power cleans and their analogs – cause repetitive forced hyperextensions of the lumbar spine. This forced hyperextension can lead to any number of physical anomalies and injury defects including lumbar sprain, strain, disc injury or a condition known as spondyloysis which consists of a fracture of the pars interarticularis (an area between the superior and inferior articulating facet on a single vertebra). Dangles et al. (3) noted a 44% incidence of spondolysis in a group of 47 Olympic lifters, while Kotani et al. (22) identified the condition in 30.7% of 26 male lifters. It is important to note that these were *experienced lifters*.

Dr. Lyle Micheli, past president of The American College of Sports Medicine (ACSM) has also indicated that ballistic weight training contributes to spondolysis (14).

While the low back region is a major concern with regard to the injury potential of these lifts, their nature embodies concern for other areas of the body as well. Dr. Fred Allman, another past president of the ACSM, has commented on numerous occasions on the danger in performing Olympic lifts, as well as the hazards of introducing speed to weight lifting movements. Dr. Allman has also stated that the performance of the Olympic lifts provides little benefit to athletes in their training programs for any sport other than Olympic lifting (9).

Kulund (23) has mentioned injuries to the wrist, elbow and shoulder while performing Olympic lifts – injuries which were obviously related to the acceleration and/or deceleration forces imposed on these areas.

Hall (17) concluded from her study on the clean and jerk that fast lifting speeds generate dramatic increases in compressive force, shear force, torque and myoelectric activity in the lumbar region.

Matt Brzycki, the Strength and Conditioning Coach at Princeton University, offers this perspective:

“Using momentum to lift a weight increases the internal forces encountered by a given joint: the faster a weight is lifted, the greater these forces are amplified – especially at the points of acceleration and deceleration. When these forces exceed the structural limits of a joint, an injury occurs in the muscles, bones or connective tissue. No one knows what the exact tensile strength of ligaments and tendons are at any given moment. The only way to ascertain tensile strength is when the structural limits are surpassed” (11).

Dr. Ken Leistner who has long excoriated ballistic lifting in training programs, points out that the inclusion of these movements in strength programs may, in fact be the genesis of injuries incurred later in practise in games. As Dr. Leistner states, “…the continuous exposure to acceleration/deceleration forces present when doing cleans, snatches and jerks can produce tissue damage which literally is an *accident waiting to happen*” (26). In younger athletes, the risks of damage to the epiphyseal are on the bones is also a cause for concern, as complete ossification may not take place until the late teens or older.

Some individuals take to task the injury potential of this type of weight training by citing the Zemper et al. study (40), which looks at time-loss injuries incurred in the weight room. These same individuals have interjected, “Many of the exercises used by those players would be considered speed-strength exercises…the average team can expect one time-loss injury from the weight room every three years.” The unanswered questions, however, include:

  1. How many of the injuries incurred were a result of *ballistic* training?;
  2. This survey measured acute injuries; what about cumulative trauma which was *aggravated* on the field and not attributed to the weight room?; and
  3. Is *any* injury in the weight room acceptable?

Many proponents of explosive training ignore the *single most* vulnerable area subected to the compressive and shear forces propagated by the majority of the ballistic lifts – the lower back region.

Some authors have suggested that explosive weight training movements are necessary in increasing the tensile strength of viscoelastic tissue as well as increasing bone density and strength. While it has been shown that progressive resistance training, in general, can accomplish these goals, there exists *no* definitive scientific finding indicating that explosive lifting induces a better adaption than high tension, velocity-controlled repetitions – relative to the parameters of the repetition scheme, safe range of motion, and controlled movement speed will strengthen the aforementioned tissues without the introduction of unnecessary momentum (6,7,11,15,21,25,26,31,32,38). You need not perform ballistic weight training movements for injury prevention purposes ANY MORE THAN YOU NEED TO POUND YOUR HEAD WITH A HAMMER IN ORDER TO PREPARE FOR A CONCUSSION.

Contrary to the suggestions of some individuals, injuries do occur in the weight room and have been documented in the literature (5,9,10,29,33,34). Many of these injuries can be directly contributed to ballistic lifting, not merely the failure of the participants to comply to safety guidelines. Also, it is categorically unacceptable to compare weight room injuries with sports-related injuries and to subsequently state that there are fewer injuries in the weight room. Strength training for athletes is NOT a sport, nor is it an activity where injuries should be commonplace. The comparison is ludicrious.

It should also be noted that certain sports, especially football, place inherent technique stresses on the lumbar spine (16,18,19,26,36). In light of this, performing ballistic lifts which have proven to be traumatic to the same region is hardly the prudent thing to do. For example, the Zemper study noted a total of 18 injuries involving either the lower or upper back. The majority of the total injuries were incurred by defensive linemen and offensive linemen/tight ends (19 total). It would be interesting to note the type of lifting which was being performed when these injuries were sustained, but the study fails to examine those important specifics. Zemper states that the most likely explanation for the higher incidence of injury positions is that “…they spend more time in the weight room and generally are lifting more total weight” (40). Could the actuality that these positions are also the ones most persistently directed by their coaches to perform cleans, snatches, etc., be a factor as well?

The underlying tone of explosive lifting proponents, when discussing injuries, is that they are a part of athletics, therefore the fact that certain lifts may carry inherent risks must be accepted. This thinking represents a negligent haphazard approach in the training of athletes who are not competitive weightlifters.

It is important to note that the American Orthopedic Society for Sports Medicine, an organization which happens to distinguish between *strength training* and *weightlifting* in it’s position paper, contraindicates the Olympic lifts in training regimens. Also, the ACSM, the world’s foremost authority on training protocol since being founded in 1954, recommends safer movements in their position paper and makes no mention of the inclusion of the Olympic lifts in training (6).

There is no question that the medical community needs to become more actively involved in this controversy. It is my personal belief that, with their continuous input, we will be able to slam the door on this dangerous and unnecessary type of lifting for the general athletic population.

Ballistic Weight Training is Unnecessary

It is the contention of explosive lifting proponents that ballistic lifting movements are necessary in enhancing athletic performance in addition to “simulation movement patterns and velocity and acceleration of many sports movements.” These claims are *not* supported with definitive, conclusive research data. Some individuals make numerous “suggestions” taken from bits and pieces of the scientific literature which fit into their ideology, but the smoking gun is nonexistent. At best, the conflicting data and/or lack of irrefutable findings on these matters render the entire controversy inconclusive.

Some explosive lifting proponents have conceded that, “Slow movement speed does not necessarily mean that an exercise is not explosive. A slow movement may be considered explosive if the athlete applies maximal force as rapidly as possible, although the weight moves slowly due to its great inertia.” If one performs a maximum or near maximum set of an exercise within a given repetition range, this “controlled explosion” will be in effect for the majority of the reps performed.

This type of training can be done with exercise machines, free weights and the various velocity-controlled modes (i.e., isokinetic devices). It is definitely a safer way to train and is a more efficient manner in which to train.

ANY type of progressive strength training will elicit gains in muscle hypertrophy and strength with concurrent enhancement in the contractile properties of muscle tissue (6,8,11,27,39). However, high force/low velocity movements produce longer periods of continuous muscle tensition during both the concentric and eccentric phases, thereby placing heavier demands on the target muscles (7,11,12,15,27,31,32,39).

There exists an inverse relationship between movement speed and muscle force production, which dictates that maximal tension is developed at slow velocities (though the “intent” to move rapidly is evident) and decreases as the speed of contraction increases (7,8,12,15,27,31,32,38,39). Low force/high velocity movements, are therefore less productive with respect to maximal force production and concomitant strength development.

While there exists considerable controversy in the scientific literature on the mechanisms of motor unit recruitment, the most widely accepted precept is the “size principle” of activation (7,12,15,27,32,39,40). Henneman (39) states that the size of the newly recurited motor unit increases with the tension level at which it is recruited. Basically, smaller motor units are recruited first, with successfully larger units firing at increasing tension levels. Slow twitch units (Type I) ten to be smaller and produce less overall force than the intermediate and fast twitch units (Type II A, Type II AB, or Type II B). A major difference in the speed of contraction between the Type I units and the Type II units (including the intermediate Type II fibers) is the fact that they have different degrees of myosin ATPase activity.

Myosin ATPase is intimately involved in the muscle contraction process and the fibers that have more of this activity can contract more rapidly. Also related to contractile speed is the fact that slow twitch fibers have a very poorly developed sarcoplasmic reticulum when compared to fast twitch fibers. This may help explain the response of slow twitch fibers to stimulation, as the sarcoplasmic reticulum is important for the quick release of calcium to trigger contraction. Couple this with the fact that the troponin of Type I fibers has a low affinity for calcium when compared to the continuum of Type II fibers, and a clearer picture of the differences in contraction capabilities surfaces.

There are also numerous metabolic differences between slow twitch and fast twitch units, due to oxidative properties which dictate energy production and endurance capacities (e.g., mitochondria supply, glycogen stores, etc.).

The element most germane to this discussion, however is that of neural innervation. Slow units are innervated by motor neurons that tend to be much smaller – both in the diameter of their axons and in the size of their cell bodies in the spinal cord – than that of fast motor units. In addition, the net conduction velocity is much slower in the nerves of slow motor units. These differences in innervation elicit a lower threshold of activation in the slow motor units as compared to the fast motor units. The net effect of this neural mechanism is that slow units are recruited first for nearly all activities, regardless of movement speed (7,8,11,15,27,32,39,40). It is only when the INTENSITY of activation is very great or when the slow twitch units are fatigued that the larger, more powerful fast motor units are brought into play.

Herein lies much of the controversy regarding fiber recruitment: Is there a preferential recruitment of the fast motor units when fast movement speeds are employed? Again, literature exists where “implications” and/or “suggestions” are made in favor of such an occurence, but the preponderance of currently available data do not support this viewpoint. Lesmes et al. (27) states that both muscle fiber types are actively recruited during maximal muscular contractions, regardless of the movement speed. The entire “size principle” of fiber recruitment is predicated on *muscle force production* NOT the actual *speed of movement*. Slow motor units are quite capable of inititating fast speeds of limb movement if the force requirements are low. Therefore, if the training goal is the recruitment and development of the fast twitch muscle fibers, fast weight training speeds at low intensity
(i.e., high velocity/low resistance movements) represent the *least* efficient approach. As stated by Pipes, “Speed of limb movement has little to do with intensity. If anything there is an inverse relationship… you can have speed or you can have intensity; you cannot have both” (31).

Studies by Palmieri (30) and Wenzel et al. (37) measured training speed and power development with no significant differences being found at slow, fast or a combination of slow and fast speeds. The relevance of these studies is in the conclusion of each that fast training speeds are not needed for power improvements. If controlled speed is at least as effective (if not more so) and safer than faster speed, wouldn’t the controlled movement speed be the more judicious option? More importantly, if the safety and welfare of the athletes entrusted to you truly superseded any personal preference or commercial bias in training techniques, then the choice should be quite obvious.

“Movement specifity” is a term that has long been misinterpreted by some explosive training proponents. To say that “the snatch and clean are very similar to other athletic movements such as “jumping”, is to contradict many of the basic principles of motor learning.

First of all, a clear definition of “specificity” is in order. The *encoding principle of specificity* states that the closer the influence of the practice on the test context characteristics (i.e., the competition situation), the better the practiced movements will be recalled during the test (1,2,28). Simply put, your practise drills, situations, etc., should mirror the conditions under which you will be tested. Performing a certain type of lifting movement with the hope that it will transfer to a sport-specific or position-specific task is *useless*. The central nervous system acquires, stores and uses only meaningful information when movement is required (28).

As once stated by Dr. Lyle Micheli, “…strength training has the potential to improve size and strength; skill development is something different” (25). That brief, candid statement says it all.

Perspective On Proper Strength Training

Strength training programs should be comprehensive in nature with the emphasis placed on exercising the major muscle complexes throughout their fullest range of functional motion. The selected movements should include a variety of multi-joint and single-joint exercises, utilizing a good mix of machines and free weights whenever possible, and be safe and relatively easy to perform in terms of technique.

Set and repetition schemes can be varied, but the program should strive for intense efforts, accurate record keeping, a system for progressive overload and time efficiency. Movements requiring excessive momentum for the execution and/or completion of the lift should be avoided.

Conclusion

This article was not written for individuals who are firmly entrenched in their thinking one way or another, but rather for those who are seeking to compare training information in order to make a rational, educated decision. It must be repeated and emphasized that any type of progressive overload strength training will elicit gains in muscular size and strength with concurrent enhancement in the contractile properties of muscle tissue. However, I caution the reader not to fall prey to the notion that there is a distinct advantage in producing “explosive” athletes by training them with ballistic weight movements. This erroneous proposition continues to be force-fed to the coaching community by organizations and individuals who, because of prejudiced thinking based on their backgrounds or vested interests, are married to this close-minded philosophy.

It is my personal opinion that many of the articles written by explosive training proponents are rife with ambiguous suggestions, one-sided half-truths, and incomplete misinterpretations of the scientific literature. If accepted as doctrine by those in the coaching ranks who are searching for training information, it could contribute to a higher incidence of weight room injuries – a situation that is totally unacceptable, both professionally and ethically.

    Olympic weightlifters have such a low injury rate that it’s actually statistically insignificant. You should have a chat with Gray Cook, one of the brightest physical therapists around. He has aligned himself with Dragon Door, the kettlebell (amongst other modalities) organization in Minneapolis. Can you say Ballistic!! Really, it all starts with good movement patterns, don’t have them..Get Them! Anyone walking around with impaired movement patterns will eventually hurt themselves doing just about anything, especially if it’s repetitive, ie. strength training…just cements mobility issues and postural issues and you will be in pain, sooner or later. I also don’t think that the “explosive” proponents are saying that snatching resembles a particular movement, therefore making you a better athlete, rather, snatching, jerking, etc. makes you better at movement in general…Big difference! By the way, Mannie needs to get with the 21st century, just look at his sources…so much has come out in the last 10 years. Would you like me to give a list ? Bottom line, if you are balanced (lots of people are not) and have good control of your body, snatch away! I’m going now and taking m 45 year old self (including a grade1 spondylolisthesis that I was born with) out to my garage and do some kettlebell swings and snatches.

    • Drew Baye July 9, 2009 at 5:50 pm #

      The low injury rate of Olympic lifters is more likely the result of survivorship bias than the safety of the activity. There is no general fitness or health benefit the Olympic lifts provide that can not be obtained more safely by performing other, safer exercises involving the same muscle groups.

      That’s great that you are able to train despite your spondylolisthesis, and I wish you lifelong health and functionality, but I would recommend against exercises like snatches and kettlebell swings.

  2. Erik petersen May 6, 2010 at 7:29 pm #

    Survivorship bias….that’s like a free pass for anything and everything! Like someone defending their religion, no way you will win that argument! Every “exercise” that you do must be performed slowly…yeah, just like actual human movement…R O B O T R O N I C. Apparently, all real human movement is therefore, wrong.How is it that you know more than Gray Cook, Gary Gray, Paul Chek, Mike Boyle, Stuart Mcgill…etc. Hell, even Westside Barbell! And yes, studies have shown that ballistic and plyometric movements work, that is how athletes train!

    • Drew Baye May 6, 2010 at 9:09 pm #

      Erik,

      Survivorship bias is not a “free pass”, it is a common logical error – in this case making assumptions about the appropriateness of something for the general population because of the success of a few – in this case, avoidance of injury – while ignoring or failing to consider those who were not successful.

      While many human movements are performed much faster than the speed of movement I recommend during exercise, this has no bearing on how you should strength train since there is no transfer of speed from one to the other. There is a big difference in the forces encountered between typical movements in daily living and sport and when performing movements holding a barbell or against a machine with a heavy weight selected. Fast lifting speeds do not provide any advantage over slower lifting speeds, but they do increase the likelihood of injury, which is why I don’t recommend them.

  3. Erik petersen May 8, 2010 at 6:09 pm #

    Maybe you should like at guys like Mike Boyle who trains mainly athletes. THE #1 job of an elite level strength and conditioning coach is to keep their athletes from injury, plain and simple. He uses various explosive movements. Do you know of Gary Gray, the “father of functional fitness”? Physical Therapist extraordinaire! Yes Drew, same here. I am glad the our ancestors understood this, otherwise we would not be talking.

    • Drew Baye May 8, 2010 at 7:02 pm #

      Erik,

      Pointing out that a supposed expert uses a particular method is not a valid argument for it. If the people you mention recommend explosive lifting speeds for anyone other than competitive weight lifters, I wouldn’t consider them to be experts any way. In fact, I’ve seen some of Mike Boyle’s training videos on youtube, and to call them idiotic would be a polite understatement.

      I could name professional strength coaches and physical therapists who recommend not lifting explosively, but just because someone who should be an authority on the subject says something doesn’t make it so. It’s not who says it, it’s the evidence and reasoning behind what is said that matters. So you can keep saying that so-and-so says this, and so-and-so says that, but unless you can provide a good reason for it, I’m not interested.

      Since there is no transfer of skill, including speed of performance, from strength training exercises to other activities, and since moving faster during exercise does not improve your results in any other way, there is no reason to recommend explosive lifting over slow, controlled lifting. However, since explosive lifting is more likely to injure you there is a good reason not to recommend it.

      • Kevin O'Toole February 26, 2013 at 7:50 pm #

    How should someone combine proper strength training with powerlifting or oly-lifting? Instead of doing strength workouts, say, three times a week, should strength workouts be performed twice a week and “skill” workouts once a week?

    • Drew Baye July 29, 2010 at 10:39 pm #

      AJ,

      If a person wishes to compete in powerlifting or weight lifting they should alternate general strength training workouts with workouts focusing on the specific competitive lifts. The frequency would depend on individual recovery ability.

    Sounds like Eric has his head up his ass. Since he’s 45 and has gotten away with lifting like an idiot, I guess that all the proof he needs. I’m willing to bet if he had a different experience in the past that resulted in an injury from his explosive training I think he would view this in a different light despite what his beloved Ballistic-Experts say. Then again…perhaps not.

    The connective tissues work in conjuction with the muscle. When your muscle encounters a heavy enough load at a moderate speed (such as “HUMAN MOVEMENT” in daily life) our connective tissues are able to handle the force upon the muscle with no problems. But when you try and move a heavier load deliberately fast it is very possible that those same connective tissues will NOT be able to accommodate the high forces that are now being placed upon them. You and anyone else that does this flirts with disaster. Force = mass x acceleration, Eric.

    It doesn’t take a genius to figure this out. What the so called experts are saying is very much incorrect. And although I don’t have a fancy degree or credential after my name, I do know truth when I see, hear and read it. I believe it was Mike Mentzer that once said “I don’t have exhaustive knowledge on the subject, but what I’m certain about I’m certain about”. Well I am certain about this!

  6. jay horn November 10, 2011 at 7:53 pm #

    To clarify, when I speak of forces on connective tissues, I am speaking on the joints as well. Makes sense to me. 2 + 2 = 4. Maybe it doesn’t now… Not sure.
