Avoiding Overtraining with Athletes

Exercise is an important part of a healthy, balanced lifestyle. Creating the habit of a regular exercise routine provides numerous health benefits including an increase fat free mass, lower blood pressure, and help stimulate cognitive function. It’s important to note that developing a safe and effective exercise regimen is key at any age from younger athletes to senior citizens. Poor exercise selection can result in injury, over reaching and over training. So how can you select the right program to avoid over training?

First, let’s define overtraining. Overtraining is the excessive frequency, volume or intensity of training that results 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 overtraining, aerobic and resistance. Aerobic endurance overtraining results predominantly from an excessive volume overload, this relates to cardiorespiratory training (i.e. running, cycling). Training within the appropriate heart rate zone is important for avoiding overreaching or overtraining. Equipment such as a heart rate monitors are great for those exercising at high intensity workloads to assess target heart rate zones and track progress over time.

The second type of overtraining is resistance overtraining. Resistance overtraining primarily results from excessive high-intensity overload; more specifically too many repetitions using heavy weights or too rapid a rate of progression. For prevention of overtraining, an important component would be a properly planned periodization program developed by an exercise physiologist. This type of programming allows the body to adapt to the stress (exercise) that it is being placed under at a safe rate of progression and volume of the workload.

Different types of overtraining (aerobic, resistance) have been reported to have different signs and symptoms, although performance decrements are commonly a key aspect of both. Signs and symptoms of over training are under or impaired performance, fatigue or exhaustion, mood disturbances, apathy, disturbed sleep, loss of appetite and irritability. There is a high degree of variability between individuals with regard to developing overtraining. Training practices that cause some individuals to thrive may lead to overtraining 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 in high level athletes) require sufficient recovery.

Set the Tone with Dynamic Stretching

When walking into the arena to begin exercise, whether that arena is in the gym or the great outdoors, it is important that you set the tone for the day. Your workout needs to begin with a warm-up that compliments the intensity of your exercise. The greatest threat to performance is the lack of preparation or a poor warm-up routine.  When going for a run or walk many people have a routine before they begin exercise: whether that routine is swinging their legs back and forth to create motion around the hips or twisting to the left and right to loosen up their lower back: Whatever it may be, are you consciously thinking about the activity you are about to engage in, the intensity you are about to give, the time in which you plan on exercising for and the current injuries or ailments you are battling at the time?  So much goes in to planning a workout therefore it is essential that equal thought is placed on planning your warm-up resulting in ultimately crushing your planned workout while minimizing injury or local muscle fatigue.

A large part of a dynamic warm-up is neurological in the sense that you are making a mind-to-muscle connection. The dynamic warm-up gives your body ample time to understand and process the stress you are about to place on your body so it can respond with the correct rate of force by recruiting select muscle fibers.  Take the guessing out of the equation and allow your body to go through a 15 minute dynamic warm-up to maximize efficiency.  If you’re going for a run ask yourself, what specific deficits do i have?  When you go for a run do you start to develop tightness around the ankles?  Adding in some ankle mobility would be a good idea with the objective to loosen up the ankles and get them tracking properly to disperse energy into the appropriate areas via tendons and ligaments.  Try performing walking heel raises to improve the elasticity in your calves, butt kicks to wake up the hamstrings, or work on mobility with deep squats to open the ankles and hips.

Everyone’s warm-up will be different and tailored to their specific needs required for the workout. Setting the tone with dynamic stretching  will help prevent injuries and keep your body working at maximal efficiency.

Strength Training for Endurance Athletes

Why would a runner or endurance athlete want to strength train? We all may have been the victim of a particularly brutal workout that’s left us too thrashed to go on the next days run; it would seem that the endurance and strength training mix about as well as oil and water. However, collections of studies have proven the health benefits of strength training and cardiovascular training, so there must be a way to harness the two and use them to improve our performance on the pavement.

Benefits of Strength Training:

  • Improvement of core strength (stability/form)
  • Increased muscular strength (speed)
  • Correction of imbalances caused by every day life (efficiency)
  • Decreased injury risk

Now, these benefits also cross over with endurance training right? The key is to incorporate the two correctly to receive maximal benefit.

An endurance athlete will need to consider a few things if they’re looking into start strength training in addition to their running protocol. Namely, the athlete would need to figure out when their big or tough runs are in the week and program heavy or higher intensity workouts around that. Next would be recovery. Is that athlete getting proper nutrition, sleep, and mobility work to assist with the work they’ll be adding in?

Here is a sample week- long program to get an idea:

Sunday

 Monday Tuesday Wednesday Thursday Friday

Saturday
Long Run Off Low intensity Lower Body and Easy Run Medium Intensity run Off High Intensity Lower Body

Low Intensity Upper Body/Core and optional light run

Looking at the example listed above, we can see that the lifts have a high or low intensity value, that’s used strategically to avoid overtraining or injury. Also strategically placed, the more taxing workout days (Sunday, Tuesday, and Friday) are placed a day or two apart in order to ensure that the athlete covers correctly. In most cases, an athlete will be able to complete a shorter run and a resistance training session in the same day, but this varies by person and goals. Talking to an exercise physiologist or performance professional before starting a program can increase the benefit and smooth out to programming process for someone looking to start.

The “Best” Workout for Weight Loss

Many people are constantly searching for the most effective workouts to lose weight as quickly as possible.  Unfortunately, this “magic” workout does not exist—different methods work for different people.  However, there are certain parameters that one must focus on in order to achieve a successful weight-loss program. Although it is not considered part of the “workout” section of a weight-loss program, if your diet is not in check you will most likely not lose weight.  Ask your physiologist for any recommendations they have to help kick start your journey to a lighter, healthier body.

Your first and most important priority with any weight-loss workout is cardio—increasing the number of times your heart beats per minute (through physical activity) for a prolonged period of time is essential to increasing your caloric deficit.  Caloric deficit refers to a higher amount of calories being burned from the body versus the amount of calories being taken in through eating and drinking.  That deficit is what causes our body to recruit calories from fat stores within us as metabolic fuel for normal bodily functioning and activity.  Therefore, doing cardio or moderate-intensity physical activity most days of the week will benefit you by helping create a larger caloric deficit.  According to numerous studies, including a 12-month study by Chambliss et al, exercise duration (at least 150 minutes per week) was more important than vigorous versus moderate intensity exercise to achieve weight-loss goals (1).

On average, a moderate intensity cardio workout of 30 minutes at a heart rate zone between 50-80% of a person’s heart rate reserve (HRR) can burn anywhere between 200-300 calories depending on intensity.  Other factors that determine the rate of calories burned include age and mass.  However, not only should a person attempting to lose weight perform moderate cardio or physical activity on most days of the week, they should also train one or more times at a higher intensity in order to improve their metabolic functioning. Some research experiments, including one by Yoshioka et al. explain that high intensity versus moderate intensity exercise yields significant benefits on post-exercise oxygen consumption (EPOC) as well as on fat oxidation (3).  What this means is that high intensity training causes a person’s body to burn calories at a faster rate after exercise as well as specifically burn fat more effectively.  Both of which have positive benefits in relation to weight-loss.

Another overlooked but important component of any “great” weight-loss workout includes resistance/strength training.  Building strength in the muscles that we use to perform our cardio exercises benefits us by improving our tolerance for work intensity and improving muscle endurance to last longer with our workouts. According to one study, 45 minutes of strength training created a greater EPOC and fat oxidation during the 2 hours after the exercise session (2).  This means that for two hours post-strength training, one can increase his or her metabolism and rate at which fat is burned.

In conclusion, there is no “perfect” workout for weight-loss.  Involving moderate and vigorous cardiovascular training sessions, day-to-day physical activity, and strength training combined with a proper diet are the keys to making your weight-loss program an effective one.

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.

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!
