Athletic Training

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.

How Much Exercise is Too Much? Avoiding Over Training

For many, exercise is a way of life.  A great exercise program can increase fat free mass, lower blood pressure, and stimulate cognitive function.  On the other hand, poor exercise selection can result in injury, over reaching and over training. Let’s start by defining over training (OT) and how you can select the right program to avoid OT.

OT is defined as excessive frequency, volume or intensity which can result in extreme fatigue, illness or injury (which is often due to lack of sufficient rest, recovery, and perhaps nutrient intake).  There are two types of OT: aerobic endurance and resistance training. The first type, aerobic endurance OT, results predominantly from an excessive volume overload related to cardiorespiratory exercises.  Such exercises may include running, walking, or cycling. Training within the appropriate heart rate zone is necessary to avoid OT and equipment like a heart rate monitor works great for those high intensity settings to avoid over training syndrome (OTS). For prevention of overtraining, an important component would be a properly planned periodization program. A periodization training model will strategically vary the specificity, intensity, and volume of prescribed exercises. The goal of this time of program is to maximize aerobic and strength gains while reducing the risk for injury and over training.

The second type of OT is resistance OT.  Resistance OT primarily results from excessive high-intensity overload or too many repetitions using heavy weights or too rapid a rate of progression. For prevention of OT, an important component would also be a properly planned periodization program. Working with an Exercise Physiologist is critical to help develop and progress said program appropriately. Different types of OT (aerobic, resistance) have been reported to have different signs and symptoms, although performance decrements are a key common aspect of both.

There is a high degree of variability between individuals with regard to developing OT. Training practices that cause some individuals to thrive may lead to over training in others.  It is critical to have sufficient rest between training days to facilitate the recovery process. The amount of rest, however, depends on the duration and intensity of the training program and should be individualized for each person.  Periods of high-volume or high-intensity training especially require sufficient recovery.

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)

Sports Injury Prevention Essentials

When playing a sport, training, or even performing everyday physical activities, you are unfortunately at risk of suffering an injury. Many times these injuries are accidents that can’t be predicted or prevented. But there are a couple things you can do to protect yourself from some common causes of injuries.

Warm-Up

  • A warm up is used to activate muscles groups before a bout of exercise, game, or activity.
    • Walk, jog, dynamic stretches (trunk twists, leg swings, shoulder circles etc)
  • “Cold” muscles are tight and have a great chance for being strained. Warm ups should increase your heart rate and increase blood flow to muscles (therefore warming them up).
  • Pre-activation exercises are a great way to target specific muscles groups in order to prepare them for a certain activity.
  • You either target the exact muscles that are going to be exercise or their antagonists (group of muscles that perform the opposite function).
    • Some examples of pre-activation exercises are:
      • Band resisted hip exercises before a leg work out
      • Band resisted ankle exercises before a run
      • Machine Rows (for your back muscles) before you do bench press

Stretching and Foam Rolling

  • Stretching and foam rolling can be performed either at the beginning or end of an exercise/activity
  • Both can relieve tension built up in muscles and decrease stress on joints
  • Foam rolling can be used to release trigger points in muscles to allow for better contractions and decrease the chance of any muscle damage during exercise.
    • Dynamic stretches before a workout, static stretches at the end
    • Foam roll your IT band and quads before a lower body exercise

During a Workout

  • It is very important to perform every exercise with the proper form and through the entire range of motion (as tolerated). The more strict and controlled you are with each movement, the less opportunity there is for injury.
  •  Completing the exercise through its full range of motion effectively strengthens entire muscles and leads to better mobility (ability to control muscle through entire range of motion).
    • Knees shouldn’t come over your toes and heels should stay down during a squat.
    • Bring your chest all the way to the ground before pressing all the way back up on a pushup in order to train through the full range of motion.

Don’t forget to finish with a cool down! A proper cool down should:

  • Bring your heart rate back down to normal levels
  • Prevent muscles from tightening up following an exercise
  • Better prepare you for your next workout!
