Improving Game Speed & Performance

When working with athletes, speed and agility are training essentials, along with strength. However, it is common to mistake the difference between speed, agility and acceleration. The National Academy of Sport Medicine (NASM) refers to speed as the ability to move one’s body in one direction as fast as possible and acceleration is how quickly an individual can reach their top speed from a non-moving position. Agility is the ability to accelerate, decelerate, and quickly change directions while maintaining proper posture. It is incredibly important, when training athletes, to consider what planes of movement they will be using during the course of a game, tournament or outing. Increasing speed, agility and acceleration can be a daunting task for trainers, but understanding the difference between the 3 and knowing drills to supplement each aspect will allow athletes to reach new heights.

Speed is a quality, essential to most sports. Some sports are more reliant on it than others and sometimes, it can even determine the success of one athlete over another. But, how exactly do we train for speed?

Increasing speed initially revolves around the idea of “perfecting” running technique. Arm action drills can increase coordination between our upper and lower halves, while wall-drills teach the athlete to achieve triple extension. In tandem, these rudiments provide the base for producing the most power per step and ability to cycle when at top speed. Squats, heavy sled drags, and isometric/eccentric hamstring exercises, etc. attribute to muscular development in the groups essential to speed development. Increasing muscular development and being able to “shut-off” the muscles that are antagonistic when sprinting will result in a faster athlete. Lastly, it is necessary to get out and sprint, using proper technique. Filming or using apps like Hudl are great ways to critique and help identify breaks in form.

While speed sometimes steals the spotlight, agility can turn the tides for an athlete in most sports. Athletes are required to move laterally (side-to-side) in order to defend, make quick cuts to evade defenders, or sometimes full turn into a sprint to track down a ball. Whatever situation an athlete finds themselves in, being able to quickly perform any movement at any time will give them a competitive advantage. Training to improve agility has a similar pattern to training for speed. Agility is based around motor control and proper positioning of the body. Agility also heavily features deceleration, so being able to reposition the feet to create better angles for absorbing and then producing force will make a significant difference. The main strength component for agility is a strong core. Most movements will require the upper and lower halves of the body coordinating movements. Thus a strong core will allow for the ability to dynamically stabilize and distribute force within the body more effectively.

Athletes can have natural speed and strength, but even the fastest and strongest need to be able to control their movements as scenarios change game-to-game, play-to-play. Training should emphasize developing technique, gaining overall strength and putting practice into real scenarios. After all, as Mike Robertson says, “games are won in tight spaces.”

Be Efficient: Producing Power Inside and Outside of the Gym

In order to better understand what the word “power” describes in a sports or life setting, let’s take it back to high school physics.

Power = Work/Time OR (Force*Displacement)/Time OR = Force * Velocity

Power; typically measured in watts, quantifies how much force you apply over a distance, in an amount of time. Think of power as the rate at which you execute strength, or how hard/fast can you execute a movement. Walking Uphill= Less power than Running up the same hill. Easy Enough, Right?

“Whats the deal Matt, Why is this important? I came here to learn about getting fit, not to get a lesson in physics from a meathead with a nice haircut”

Well, the reason we get anywhere is because of power. Power is the ability to take our strength (force) and apply it to Movement at a rate of speed (See Equation).  Think walking down the stairs to catch the bus, throwing your coffee in the air when the neighbor’s cat scares you, chasing after the bus when you miss it because you spilled your coffee (but enough about my day, I digress). All of these actions are different measurements of power.

“Ah, I see where power fits into our lives, but I don’t play sports, how is power important to me?”

Not entirely! Yes, a softball player should be able to swing her bat hard, and a swimmer should be able to move quickly through the water, but all of these sports contain skills that we use in day to day life. Think throwing, jumping, running, twisting, changing direction, etc. Additional benefit to training power would be more applicable strength, improved athletic performance, joint resiliency, decreased fall risk, and improved cardiovascular health …(Don’t believe me? Try doing box jumps for 30 seconds, total soul crusher.)

“Onto the nitty gritty; how do I get better at this power thing?”

Reader, you’re in luck. Specificity states that in order to get better at something, we need to practice that thing. To become a more powerful everyday athlete, work in a power day or a few power focused moves into your current routines. Take a look back at our definition of power and we can see that it involves applying force quickly. Think jumps, tosses, slams, etc. A shoulder press translates to a med ball overhead toss, a box squat to a box jump, planking to heavy carries, and the list goes on. Talk with your exercise physiologist about incorporating power training specific to your goals and abilities!

Tapering for Optimal Performance

After periods of intense training, the best performances in strength or endurance sports usually occur following an appropriate taper phase.  A taper is a progressive and non-linear reduction of a workload during training for a period of time prior to competition.  In other words, after weeks of routine training workouts, where the intensity or volume is strategically increased for a period of time, there is a large reduction in the training load in the week or two before a competition or event.  This tapering technique is designed to avoid injury, overtraining, psychological stressors and/or extreme fatigue prior to the event in order to achieve maximal performance.

There are multiple facets as to why a pre-event taper is vital to achieving the best performance possible.  Changes in the cardiovascular system include an increase in maximal oxygen uptake (measurement of endurance), and possible hematological changes including increased blood volume, hemoglobin (oxygen carrier within the blood), hematocrit (volume of red blood cells within the blood), reticulocytes (indicator of bone marrow activity), as well as, a reduced red cell distribution width.

Tapering also causes positive metabolic changes as well.  These changes include a reduced daily energy expenditure, reduced respiratory exchange ratio (recruiting fat more efficiently for fuel) and an increased peak blood lactate concentration (greater exertion and higher threshold for work performance).  Lastly, muscle glycogen concentrations increase and calcium retention mechanisms are triggered during a taper, allowing for optimal muscle contractions and a greater stored energy within the muscles (2).

According to a research study completed in 2014 at the Laboratory of Sport, Expertise and Performance, the most efficient taper strategy for maximizing performance gains was to perform a 2-week taper with an exponential reduction in training volume by 41%-60% without any modification of either training intensity or frequency (1).  In other words, reducing load or speed and reducing the amount of exercise sessions per week were found less effective than reducing the volume of each workout.  For example, a reduction in volume could be performing 1 set of an exercise when you normally do 2 or 3 sets.  Another important finding of this study is that a period of overtraining prior to initiating a taper has been found to be even more effective than just a tapering phase itself.  However, the degree of overtraining prior to the taper is crucial because too much performance supercompensation can lead to worsening performance.

When working with a coach, whether it is for running, strength training, or general sports conditioning, be sure to discuss the appropriate taper period for you. Programming a reduction in the volume of exercise may be beneficial to your performance in your race, game, or competition.

ACL Injury Prevention in Young Athletes

Knee injuries are common among athletes of all ages. Mostly common are tears or sprains of the the anterior cruciate ligament, or ACL. This small but powerful ligament works with the posterior cruciate ligament (PCL) to allow the knee to bend back and forth. It also helps to prevent the tibia from sliding out in front of the femur. The ACL also works to keep the knee stable during rotational movements.?

Athletes who play high-demand sports such as football, soccer, and basketball are most at risk of tearing an ACL. There is a risk of both contact and non-contact injury while playing sports. Even still, a majority of ACL injuries are non-contact. Female athletes are at an even greater risk of tearing their ACL. There are several factors that put females at a higher risk, including: overall strength (specific to the hip joint & lower extremity muscles), high Q angle (angle from the knee to the hip), and an inward collapse of the knee upon landing (valgus). Two of these factors can be modified with proper strength training to reduce the risk of injury. More often than not, however, athletes are focused on skills for their sport rather than strengthening. This is the greatest risk of all because weak athletes get injured.

Implementing a program comprised of both strength exercises and jumping/ plyometric movements with younger athletes is key to help reduce the risk of injury. These types of programs are more often done at the collegiate level, however, youth and high school athletes should implement strengthening in addition to skill work.  Exercises, such as the ones below, should be performed regularly, and executing them with proper form is vital. Warming up is essential to prime the muscles and the joint for movement. As the athlete builds strength in both bi-lateral and uni-lateral movements, they can then progress to performing plyometric movements. These exercises focus on developing power and proper landing form. The best injury prevention is prehabilitation- strengthening before an injury occurs to ultimately decrease the athlete’s risk on the field.

The following are some examples of warm-up, strength, and plyometric exercises that could be used in an ACL prehab or rehabilitation program.

Warm-Up

  • Jog forward
  • Backwards fire up hip extensors and hamstrings
  • Side to side shuffle- engage inner and outer thigh muscles and hips

Strengthening

  • Squats (advance to Goblet squat)
  • Single Leg RDL (increase SL Stability & strength the posterior chain)
  • Split Squats
  • Planks (focus on core & glute strength)

Plyometrics

  • Jump/ Landing Technique
  • Drop Jumps
  • Box Jumps
  • Bounding (Forward/ Lateral)

Returning to Exercise After a Heart Attack

Myocardial infarctions, better known as heart attacks, are one of the leading causes of death in the United States. Generally, heart attacks are a result of coronary heart disease (CHD). With CHD, plaque begins to buildup in the coronary arteries leading to a reduction of oxygen-rich blood to our heart. If the plaque builds up too largely and the heart does not receive enough blood, the heart muscles start to die. At this point, heart damage is not obvious and severe or long-lasting complications can occur, including a heart attack.

Symptoms are not always present in CHD and but there are a few major symptoms associated with a heart attack. These include chest pain, upper body pain above the belly button and shortness of breath. Thankfully, heart attacks and CHD are preventable and many risk factors can be controlled. The risk factors include:

  • Smoking
  • High blood pressure
  • High blood cholesterol
  • Obesity/Overweight
  • Lack of physical activity
  • Unhealthy diet
  • High blood sugar due to insulin resistance or diabetes

*Items in BOLD can be further controlled by increased physical activity

In the event that someone has experienced a heart attack, it is possible to return to normal activity. Most people that do not experience chest pain or discomfort or other problems will typically return to normal activities within a few weeks and walking can start immediately.

When programming for an individual that has had a heart attack it is important for them to ease back into exercise. The key is to slowly build up to being able to withstand 30 minutes of moderate intensity activity. During this period, low-impact movements like walking or light gardening are preferred. As the individual gets stronger and gains stamina, others activities like swimming, cycling or non-contact sports can be added.

Strength training is not recommended in the short-term and, apart from light weights during the early recovery period should be avoided until a physician or cardiac rehabilitation team confirms approval to begin. This is due to the spike in blood pressure that is associated with heavy lifting.

If you would like information pertaining to CHD or myocardial infarctions be sure to check out my.clevelandclinic.org. Also, be aware that most patients will receive a prescription for cardiac rehabilitation, which has been an effective program for recovery post-myocardial infarction. Feel free to ask any of our fitness professionals any questions you may have.
