Factors Affecting Human Performance
In order to maximize human performance, you must have a good understanding of what affects performance. The factors that play the greatest role in performance are:
Power (Strength and Speed) - Agility (Flexibility/Mobility/Stability)
- Cardiovascular and Respiratory Conditioning
- Sport Skill (Neuromuscular Coordination and Efficiency)
- Genetic Potential
Let's take a look at each factor and determine which training methods are going to deliver optimal results. By optimal results, I mean the greatest amount of improvement, with the least amount of risk, and in the shortest amount of time.
Power
Power = Force x Distance / Time
Power can be increased three ways:
- Increase Force (Strength)
- Increase Speed
- Increase Distance (flexibility/range of motion
1. Increase Force (Strength)
What is the most effective method of increasing strength and/or muscle tissue? In my opinion, High Intensity Strength Training is the most productive, safe, and time efficient approach available. I am not stating that one set of each exercise is the best choice. My definition of High Intensity Training is: training to momentary muscular failure, with brief and infrequent workouts in which all variables are prescribed based on the individuals: goals, age, current fitness level, fiber types, personal preference, and past experience.
The purpose of strength training is to increase strength and lean body mass, NOT for training a specific skill or movement-that's called practice! People strength train for many reasons and there are many methods that work. For years, many trainers and coaches have had their clients and athletes perform Olympic lifts because they feel it will transfer over into the performance of their skill.
Numerous studies have shown that the neurological transfer of skills is not optimal unless the skill is practiced EXACTLY as it is performed in competition. Therefore, performing power cleans because you play football is NOT optimal. Performing power-cleans will only get you better at performing power-cleans! Focus on increasing strength and lean body mass, and practice your skill exactly as it is performed during competition.
2. Increase Speed
Increasing the speed at which a skill is performed is another great way to improve power. Speed is primarily predetermined by the individual's genetic make up. However, that does not mean that you cannot improve speed by practicing the skill EXACTLY as it is performed in competition. A great deal of focus should be placed on perfecting the technique. By practicing the skill in this manner, you will improve neuromuscular efficiency, which will result in faster and more accurate performance.
3. Increase Distance (flexibility/range of motion)
Increasing flexibility is another way to improve power. By increasing flexibility, you increase the distance that force is applied which results in an increase in power.
The safest and most effective method to increase flexibility is by performing full range of motion exercises and incorporating a sound stretching routine.
Agility
Improving ones agility is another way of optimizing performance. Agility drills should be SPECIFIC to the activity or event. For example, having someone do Plyometric jumps off of boxes is NOT specific to someone who plays basketball! Yes, a basketball player jumps, but not off of boxes. Having the athlete practice jumping from the floor would be much more specific to their sport. Always ask yourself, "What is the goal?" "Is what I'm doing going to give me the outcome I desire?" "Is it optimal?"
Cardiovascular and Respiratory Conditioning
Increasing cardio/respiratory output and endurance is another factor that has a major impact on performance. This topic is one of such importance that it is beyond the scope of this article. In general, if you increase the individual's cardiovascular and respiratory output and endurance, there will be a corresponding increase in performance.
Cardiovascular training should also be specifically geared towards improving the individuals conditioning in the metabolic pathway in which they compete or perform. For example, someone who plays tennis should primarily train at a slow to moderate pace and incorporate bursts of high intensity effort. Interval training would be a good choice for this individual. Keep the training specific to the individual.
Sport Skill
This is an area in which there is a lot of confusion among many athletes, coaches, and trainers. Skill acquisition and strength levels are two completely different things. Therefore, they should be trained separately, and with different methods. In order to optimize the performance of a specific skill or movement, it needs to be practiced EXACTLY as it is performed in competition. It has been shown that each activity or movement has it's own neuromuscular pathway, and that just because a movement is similar does NOT mean there will be a positive transfer or carryover of skill.
In order to maximize performance the individual should attempt to perfect their movement or skill with endless hours of practice. The goal of practice should be to improve the technique, accuracy, and increase the speed at which the skill can be performed. This topic was addressed earlier in the section titled "Increase Force."
Genetic Potential
This is the factor that I have found to have the greatest impact on human performance. Genetic potential is something many people overlook. Regardless of what methods of training I use, I will never be a world-class marathoner. I can train twice a week or I can train 5 hours a day, it still won't change the fact that my body wasn't designed to excel at endurance activities. I hear of too many coaches and trainers having people follow dangerous training programs in an attempt to drastically improve their performance. This is not to say that you cannot improve performance. When training yourself or a competitive athlete, always set realistic goals. As stated earlier, the best thing to do is utilize the most effective methods available and work hard!
