As a living, breathing, blog reading individual you’ve probably learned the basics around how food provides the body with energy. There are actually several different ways that this can occur and they depend on the activity being performed. Depending on our sport or activity, nutrition, genetics, and level of training will each play a role which energy system is primarily utilized. As you can see in the pictures above these athletes have trained to optimize a certain energy system in their body to improve performance at their respective sport. Regardless of which energy system is predominantly used all energy is stored in the form of ATP.

Adenosine Triphosphate or “ATP” is the energy currency of the body. Each of the energy systems in the body have their own way of producing ATP to power our daily activities. There are pro’s and con’s to each energy system but ultimately having a better understanding of how our body uses energy can help us make informed decisions on diet and exercise. Let’s learn about each energy system…

Alactic System aka the Creatine Phosphate System
Lactic Acid System aka Glycolytic
Aerobic System aka Fatty Acid Metabolism

“No matter how many mistakes you make or how slow you progress, you are still way ahead of everyone who isn’t trying.” —Tony Robbins

Alactic System

(aka the Creatine Phosphate System)
What is it: The alactic system utilizes creatine phosphate (CP) as an energy source. It fuels high intensity efforts. Creatine is able to donate its phosphate molecules to the the Adenosine Diphosphate (ADP) molecule allowing it to return to ATP, with potential energy stored in its chemical bonds. Creatine comes from the food that we eat with the highest levels in red meat, pork, poultry, and fish. It can also be supplemented for vegetarians and vegans.

Time domains: This energy system is exhausted in 8-12 seconds for most individuals and you will fatigue when your CP and ATP stores have depleted. It is great for quick bursts of energy.

Efficiency:It requires 30 seconds to 2 minutes to replenish energy stores.

By products: Heat released from the breaking of chemical bonds.

Examples of activity: You may see this energy system in action through the short powerful bursts seen in weightlifters, powerlifters, pitchers, and shot putters.
What training looks like: Training the CP system means using short time domains with long rest periods in between. In the gym this means keeping rep ranges to sets of 6 or fewer reps.

Lactic Acid System

(aka Glycolytic system)
What is it: The lactic acid system utilizes glycogen (glucose stored in the muscles and liver) as a fuel source. It is for longer lasting high intensity activities. Our body is able to store about 500 total grams of glycogen in the muscle and liver tissue which provides around 2,000 calories worth of energy. Running out of this fuel source is commonly referred to as “bonking.” Some athletes consume carbohydrate foods, drinks, and supplements during training and competition to prevent running out of this valuable fuel source.

Time domains: It is the primary fuel source for activities lasting from 30 seconds to about 3 minutes. You know you have fatigued this energy system when hydrogen ion accumulation causes a burning sensation in the muscles.

Efficiency: The lactic acid system is very efficient at providing fuel but fatigues quickly. Due to the long recovery time it is favorable to alternate levels of intensity between glycolytic and aerobic dependence to sustain high output.

By products: The byproduct of this system is pyruvate. Which must be cleared from the blood to continue to utilize this energy system. This can take 30-60 minutes.
Examples of activity: This energy system would rule during a 400 or 800 meter sprint, a hockey lines time on the ice, or most CrossFit workouts. It is seen in mixed use with the aerobic system during longer workouts or soccer and basketball games where the players alternate between a slower jog pace with periods of intense sprinting and jumping.

What training looks like: To train this energy system you can utilize interval style training. Intense bursts of energy followed by a recovery period that allows you to stay at a threshold of high output. These athletes tend to have increased muscle mass and ideally lower body fat percentage.

Aerobic System

(aka Fatty Acid Metabolism aka Krebs Cycle aka Citric Acid Cycle…)
What is it: This is the creation of energy from fat, glycogen or protein in the presence of oxygen used to power low and moderate intensity activities. The mitochondria present in muscle cells takes the available fuel source through a variety of reactions to produce ATP. Since fat molecules packs 9 calories per gram they tend to be the main choice for this energy system. Even the leanest individuals carry enough body fat to fuel many days worth of activity.
Time domains: Any activity lasting more than 3 minutes in duration.

Efficiency: This system produces energy much more slowly than the others. The good news is it can utilize an unlimited fuel supply of fat.

By products: The aerobic system only produces water and carbon dioxide when generating ATP.

Examples of activity: This energy system is your predominant fuel source for jogging, cycling, swimming long distances, and most of your daily activities.

What training looks like: Athletes who have become efficient at using fat as a fuel source are able to convert the energy from fat more quickly, allowing them to sustain higher levels of work capacity for activities with long durations. These athletes are usually easy to spot as they have exceptional muscle definition and extremely low body fat.

As you can see from the graph, our average work capacity is dictated by the length of time we are performing an activity.By training in all three energy systems we can become more efficient in all areas, thus increasing our work capacity across the board.Individuals who only try to utilize cardio or lifting heavy weights to improve work capacity will fall short of their well rounded counterparts. If you’re an individual who wants to improve general health it is beneficial to train each of the energy systems.

“An ounce of prevention is worth a pound of cure.” -Benjamin Franklin

Life is unpredictable and sometimes in our sports, exercise, and daily life we come out of these unpredictable situations a little bit worse for the wear…

Some folks try to prevent these situations from happening through avoidance, but if you want to have a high quality of life I highly recommend you adopt a strength training program as your physical insurance program. This is certainly a much more proactive approach to mitigating physical injury than hoping for the best.

“If you train hard, you’ll not only be hard, you’ll be hard to beat.” -Herschel Walker

Or if you are an athlete like Robert Griffin III (pictured above) you may want to consider the risk factors of your sport. Robert, aka RG3, came into the NFL and was an instant phenom and fan favorite for his dazzling display of athleticism that was so uncommon in quarterbacks. His jukes, spins, and leaps were no match for the demands professional football places on an athlete and RG3 has spent most of what was once a promising career watching from the sideline, injured.

You see, despite his athleticism, RG3 has not trained in a way that reinforced a fundamental movement pattern. As we look at the series of pictures highlighting the windup before an explosive jump, We see a valgus knee fault where his knees cave in creating a very compromised position for the joints of his lower extremities. Even though not all injuries are preventable, by focusing more on proper technique and exercises that stabilized the knee joint rather than increasing strength and speed RG3 may have avoided some major injuries in his career.

“There are no shortcuts to any place worth going.” -Beverly Sills

So what should a workout look like?
Exercise should replicate natural human movement patterns. The ones we encounter on a day to day basis. Squat, lunge, hinge, push, pull, rotate and walk. Most exercises fall into at least one and sometimes several of these movement patterns. By addressing all of them in our training we not only improve our functional strength but also prepare our bodies for anything life could throw at them.

In one study published in the American Journal of Sports Medicine there was an 88% overall reduction in ACL injury rate in an intervention group of soccer players who participated in an injury prevention program. The right knowledge and a little consistency can go a long way when it comes down to keeping your body healthy.

Is your current training program addressing mobility, recovery, full range of motion, and then total body strength?

If you have suffered from injuries in the past or have concerns with your mobility it is important to address those with your trainer or coach. They will be able to help you by assessing the area of concern and designing a program to help you improve function with goals and checkpoints along the way. It is not always fun, easy, or sexy to do but giving attention to our problem areas will be easier to do the sooner you start.

Fitness trends come and go and most fall to the wayside for good reason.

Most programs fail to produce consistent results. It’s a wonder why so many folks stray away from what is tried and true when it comes to exercise programs?

“The rule is: the basics are the basic, and you can’t beat the basics.” -Charles Poliquin

Despite what your goals may be, every individual can benefit from physical resistance training. Not only that, but the health benefits extend far beyond your short term fitness goals. Regardless of why you train, let’s take a look at some of the reasons you should incorporate strength training into your fitness regimen.

1. Training for strength produces results.

Whatever your goals, muscle will help you get there. Some companies in the fitness industry has made a fortune around buzzwords like “tone”, “lift”, and “sculpt.” The problem is there’s no way to measure those loose terms. If you want to change your body composition there is only the ability to gain or lose muscle while simultaneously gaining or losing fat. If you are looking for the most efficient way to do make a change then strength training is your best option.

Strength training, or physical resistance training, can be defined as a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles. When you gain muscle you increase your bodies basal metabolism (the amount of calories you burn each day before factoring in physical activity). It’s kind of like putting a bigger engine in a car. The car is capable of moving faster or pulling a heavier load (more muscle), but it also uses more fuel (fat) whether it’s cruising down the freeway or idling in the driveway. Strength training helps us “tone” through this muscle gain/fat loss trade.

2. “You can’t manage what you can’t measure.” -Peter Drucker

Training for strength provides a clear path for success. You can set training goals that are specific, measurable, and produce desired outcomes. A good coach will help you design a plan towards these goals with checkpoints along the way. Your strength training program is a road map to success with clear directions. Sets, reps, and weights lifted safely through the full range of motion are the signals that you’re on track. Many people find that a more detailed plan helps them stay motivated as they experience progress.

3. Age gracefully with more muscle mass.

As we get older strength training is one of the most important things we can do for our health. Physical independence is a key factor in a great quality of life.

A comprehensive study of strength training has been proven to:

• Improve motor function
• Lower resting heart rate
• Increase stamina
• Prevent sarcopenia (age related muscle loss)
• Improve bone mineral density
• Prevent and help rehab injuries

Functional strength training will be an asset in daily life too. From picking up grandchildren or bags of groceries to climbing stairs with confidence.

4. You’ll experience epic brain gains.

Did you know that lifting weights can strengthen your brain just as much as it does your body?
Dr. Yorgi Mavros from the University of Sydney has found that high‐intensity physical resistance training (PRT) results in significant improvements in cognitive function, muscle strength, and aerobic capacity in older adults with mild cognitive impairment. Adults who followed a resistance training routine in addition to cognitive training performed significantly better than control groups on a series of mental tests. A couple key factors to note:

The participants exercised 2x/ week working to at least 80% of their peak strength.
The benefits lasted one year after the exercise prescription had ended.

What does that mean? According to Yorgi, “The stronger people became, the greater the benefit for their brain.” Let that sink in for a minute. You actually grow your brain by training to become stronger! It makes me wonder if Einstein developed his Theory of Relativity in between heavy sets of back squats…

5. Strong moms have healthy babies.

During pregnancy, the question always arises of what does fitness look like for this stage of life? With so much on the line, it’s important to consult with a doctor before beginning any fitness routine. Luckily, there is a tremendous amount to be gained by incorporating a strength training routine under normal circumstances. Resistance training can help alleviate symptoms and improve health outcomes for the mother and child. According to the Mayo Clinic, women who follow a consistent strength training routine during pregnancy can experience:

• Reduce backaches, constipation, bloating and swelling
• Boosted mood and energy levels
• Better sleep
• Prevent excess weight gain
• Maintain levels of muscle strength and endurance
• Reduced incidence of gestational diabetes

Not only that but women who train during pregnancy report enhanced body image and better psychological well-being!
