The emphasis of many athletic development programs is typically rooted in developing the physical qualities needed in the sport of competition. Physical qualities usually emphasized are endurance/work capacity, strength, body awareness, agility, quickness, speed, and explosive power. Improvements made in any of the previously mentioned physical qualities can certainly improve an athlete’s fitness and physical preparedness for competition. But great athletes are rarely defined by their level of fitness and how ‘in-shape’ they are. They are defined by their ability to play the game and perform the skills of the sport. Great coaches and trainers understand this, being able to take an athlete’s newly developed physical qualities and transfer them to into improved skill execution or technical mastery of sport related movements.

This is accomplished by specificity of training.

In order to ensure specificity of training, it is first necessary to determine the exact physical qualities an athlete is in greatest need of. Many coaches and trainers refer to this as ‘identifying the deficiency’. Once the deficiency is identified and an understanding is developed as to how the deficiency is limiting on-field performance, the deficiency can be trained appropriately.

To identify deficiencies, the majority of coaches and trainers utilize tests to determine an athlete’s level of strength, endurance, explosiveness, and even flexibility. While these tests are often necessary and provide quantitative information that will help assess how an athlete stacks up in comparison to others, what these tests fail to indicate is how efficiently an athlete can perform sport-specific skills or maneuvers.

Physical performance tests fail to indicate an athlete’s needs in relation to game performance. To ensure transfer of training into improved sport performance, identifying an athlete’s developmental needs must take into account an analysis of all components involved in successful competition. Often, this involves a complete biomechanical analysis of movements related to sport-skill execution.

For example, the deep squat is often a staple of many strength and conditioning programs. It can be a tremendous exercise for building hip strength and power and for a variety of other reasons. But when you examine the sport-related movements of many athletes, one can come to the determination that the need to deep squat is not a priority for many athletes. Consider hockey and basketball players. These sports require hip external rotation strength and power to execute sport-specific movements (skating, lateral cuts, change of direction, etc.). Rather than placing greater and greater emphasis on improving strength in the deep squat, these athletes will be better served in developing hip external rotation through other exercises which more closely mimic the external rotation demands of the hips in competition.

Again, great athletes are rarely the strongest or the fittest. There are studies that demonstrate Olympic-level athletes and World Record holders are not the strongest athletes (with the exception being in strength sports such as powerlifting and Olympic weightlifting). Athletes on the highest levels of performance do not lift the greatest amount of weight in commonly used exercises, such as the clean, squat, bench, or deadlift.

More commonly, athletes will fall in the midrange of strength numbers. What this is demonstrating is a ‘point of diminishing returns’. Many athletes reach a point at which increases in strength or other physical qualities do not always equate to improved sport performance.

Successful athletes must be able to execute sport skills with technical mastery and precision. Regardless if you are a hockey, football, soccer, lacrosse, baseball, tennis or track athlete, you need great acceleration, speed, agility (ability to change direction quickly), and the ability to jump high (which also requires explosive power). But arguably most important is the ability to perform all sport skills with mastery and precision of movement.

An athlete will never be successful if they do not have the ability to execute sport skills successfully. This is why technique must be closely analyzed and why the training of physical qualities must directly enhance the performance of sport-specific skill execution.

Analyzing an athlete’s sport skill technique and the demands of game play becomes a necessary first step to determine exactly what their training program should consist of. Often to correct and/or enhance technique, special strength exercises are implemented to develop the specific strength an athlete needs to execute movements more efficiently.

We addressed special strength exercises in this article. Special strength exercises are intended to replicate the exact neuromuscular pathways utilized in the execution of specific sport skills.

With proper analysis and identifying the ‘deficiency’ of the athlete, it enables the training program to have greater transfer into sport performance. The training program is continually adjusted as improvements in strength, speed, agility, and explosive power are integrated into technical mastery of skill execution.

High-intensity interval training (HIIT) is a system of training characterized by high-intensity resistance or metabolic training with short/incomplete rest periods in between working sets. An example of HIIT is often advocated by Crossfit WODs (workout of the day) and other similar programs.

According to the American College of Sports Medicine, HIIT is now the most popular fitness trend. HIIT has tremendous appeal to those looking to shed unwanted body fat and ‘lean up’ or ‘get in shape’ quickly because of its ability to burn body fat more efficiently. HIIT has been shown to produce greater improvements in both aerobic and anaerobic capacity with less overall training volume when compared to individuals who only perform steady-state aerobic exercise. In the public eye, a huge upside to these workouts is they typically take less than 30 minutes to complete. Sounds too good to be true, right?

However, what is rarely if ever mentioned, is the number of injuries sustained by participants.

In my opinion and experience, which may be similar to what others are also observing, the number of injuries associated with HIIT appears to be on the rise. What is especially significant to note is that these injuries are often debilitating in nature.

Not only is HIIT growing in popularity among the general population, but it also seems to be a growing trend among athletes. The point of this article is to discuss why HIIT is not an appropriate training program for athletes and provide some insight into why athletes should avoid programs that advocate high-frequency application of HIIT methods.

Why Athletes Should Avoid HIIT
First and foremost, when training with heavy weights or performing complex motor skills (i.e. jumps, throws, sprints) it is highly critical that proper technique is learned during the initial stages of training. This is the key to not only continual development in regard to strength and all other physical abilities, but is fundamental to injury prevention.

Proper technique is the key to ensuring that strength developed becomes more useful not just in athletic skills, but also in everyday activities. For athletes, proper technique serves as the foundation for efficient execution of sport-related movement skills.

So why does HIIT fail athletes?

What appears to be most important in HIIT is overcoming a prescribed amount of resistance or finishing a prescribed number of reps in a designated amount of time, regardless of how it is done. From the start, HIIT does not place technique as the number one priority. For your viewing pleasure, Youtube provides numerous examples of this. I can recall watching a Crossfit workout during which a young female participant is doing her best to finish an overhead press. She had to contort her body in every way imaginable in her attempt to get the bar locked out overhead. Needless to say, I did not like what I saw.

What was even more disturbing to me was hearing the other members of the class cheering her on and applauding her when she finally locked out the bar overhead. They were encouraging her effort with absolutely no attention or care about her technique and safety. This is just one example of many that indicates how overcoming the weight was more important than how the lift was performed.
Other daily workouts may prescribe high-intensity metabolic conditioning that often requires participants to train to the point of exhaustion and, sometimes, to the point of throwing up. The mindset and main objective is primarily focused on overcoming a specific quantity of work as opposed to expressing quality in the work.
It is this mentality that can be detrimental to athletes and the general fitness population as well. There is a reason why physical therapists and chiropractors love Crossfit and other HIIT programs. HIIT programs are pretty good at producing patients.

Another unwanted factor associated with HIIT is the high degree of fatigue and lactate training loads. For athletes, how can they master movement and skill execution or build speed and strength in a fatigued state? The answer is they cannot. This is something the majority of coaches and trainers must understand. Lactate-based training is widely over-utilized and misplaced. This ultimately cuts into more productive training methods and increases the need for recovery. When it comes to HIIT programs, recovery is often not sufficient and will potentially push participants into a chronic state of fatigue or create an over-trained individual. Keep in mind, injuries are more likely to occur in a fatigued or over-trained state.

When it comes to HIIT, training principles regarding periodization, progressive overload, mastery of technique, specificity of training, and individualization of training are completely ignored. These principles, among others, are highly important when it comes to the safety and effectiveness of training athletes. They have been proven to be foundational in producing the most effective results from any training program.

Final Words
Training and sport science tells us that HIIT programs or any randomized high-intensity program is not conducive for efficient training and development of athletes in regards to strength, speed, power, and other physical abilities. Sure it may be trendy, but ask yourself does the program or exercise routine provide the development you want? Remember, development is always specific to your training demands. Also, ask yourself if your current training methods are more likely to make you a better athlete or a patient.

The Olympic lifts (snatch, clean and jerk) and their variations are often used in the training and preparation of athletes that require explosive strength and power. Although Olympic lifts may be useful for teaching an athlete of low preparation how to rapidly generate force, overall they are not ideal for developing explosive strength for a number of reasons. Of primary importance is the increased risk of orthopedic injury associated with Olympic lifts, namely the overhead portions. So how does one efficiently develop power and explosive strength without undue risk of injury?

If the end goal is to improve explosive strength of the leg and hip musculature, as measured through vertical jump and standing long jump, coaches must select the most efficient and safest means. Charlie Francis placed sprints, jumps, and throws just as high as the Olympic lifts on his motor unit recruitment chart. Sprints, med ball throws, weighted/unweighted jumps all become wiser alternatives for power development as they require far less time to learn and impose less risk of injury.

This is not to say Olympic lifts serve no purpose. They certainly can be useful, but their positive effects are greatly misinterpreted by most coaches. For instance, some coaches utilize various volume and intensity schemes with the Olympic lifts to develop bioenergetic pathways used in acceleration phase of sprinting. Others will use it to develop tremendous starting strength. Keep in mind, there have been Olympic-level weightlifters with remarkable vertical jumps. Some have the ability to keep pace with or beat Olympic-level sprinters in the first 30m out of the blocks.

This sounds like pretty amazing stuff, right? Simply hit some cleans and snatches to get powerful and fast?

However, there's a big problem.

You aren’t as good at the lifts as an Olympic-level weightlifter. Remember, weightlifting is a sport. It is a skill and unless you have a lot of years under your belt, perfecting the lifts, you aren’t even remotely close to having the lifts make a significant impact on your athletic performance.

If you are going to get the most out of training the Olympic lifts, it absolutely matters that you are skilled from a technical viewpoint.

For example, outside of elite status Olympic weightlifters, very few lifters actually achieve full hip extension during the lifts. Meaning, they aren't fully developing powerful hip extension. Full, powerful hip extension is essential to developing explosive athletic qualities seen in sprinting, jumping, and throwing.

So, as an athlete, why would you perform a series of exercises that are ultimately going to take years of practice to learn while reaping little benefit from that effort? Sure, plenty of people think they have "learned" the lifts, but reality is they are far off the mark.

It takes time, a lot of time, to learn how to do the lifts properly. Achieving rapid, full hip extension is not an easy task and don't let anyone convince you otherwise. Nobody ever mastered the lifts in a matter of weeks.

So when it comes down to appropriately addressing power-speed development in athletes, it should become clear that there is potentially wasted time and energy in truly learning the Olympic lifts. Similar training results can be achieved with more basic exercises without the high technical demands.

Looking for ways to develop powerful hip extensions? Variations of sprints, jumps, and med ball throws get the job done faster with greater dynamic correspondence. Unless you are competing in weightlifting, the Olympic lifts don't offer much in dynamic correspondence to many athletes. Consider movements specific to your sport. Whether it is skating or shooting in hockey, throwing a baseball, covering a wide receiver, or kicking a soccer ball, there are very few specific connections with the Olympics lifts when you look at the movement patterns.

For an athlete, the Olympic lifts become very general in their ability to train resisted hip extension and reactivity.

As an athlete, your goal is to get better at your sport. Specificity in training matters. You could be wasting valuable time and energy resources on learning lifts that have little impact on your abilities to perform in competition.

Concluding Thoughts
I’m not here to bash on the Olympic lifts. They can serve a purpose in developing explosive hip extension and reactive/plyometric qualities. However, there are problems that exist with their use and implementation in the training programs of athletes. As mentioned previously, outside of competitive weightlifters, the Olympic lifts lack specificity. Specificity and dynamic correspondence are critical for any athlete. The Olympics lifts also impose greater structural risk and this could be considered unnecessary when developing athletes. The goal of athletic development is to maximize training results while minimizing structural risk. Consider variations of sprints, jumps, and throws. These alternatives are easier to implement and progress, thus providing both athletes and coaches the ability to master power-speed qualities specific to the athlete's sport form.
