The Science Behind Your Golf Game: Understanding the Energy Systems That Drive Performance
Understanding how your body produces energy can help you train smarter, recover better, and perform consistently from the first tee to the final putt.
When we think about golf performance, we often focus on swing mechanics, clubhead speed, strength, and mobility, like Roger talked about in his article last week.
While all of these are important, there’s another piece of the puzzle that I’ve never discussed before: how the body produces and uses energy.
A golf swing is a short-duration, explosive movement that requires the body to generate force and power quickly. However, a typical round lasts four to five hours, involves several miles of walking, and requires golfers to repeatedly produce these explosive movements while managing fatigue.
So how does the body meet these demands?
To understand this, we need to look at the three energy systems responsible for producing the energy our muscles need to work: the ATP-PC system, glycolytic system, and oxidative system.
Understanding the Three Energy Systems
Before connecting energy systems to golf, we need to understand ATP (adenosine triphosphate). ATP is the body’s immediate source of energy for muscular contractions. Because our muscles store only a limited amount, the body must constantly regenerate ATP to keep us moving.
This is where the three energy systems come into play.
All three systems work simultaneously, but their contributions change depending on the intensity and duration of activity.
1. ATP-PC System (Phosphagen System)
The ATP-PC system provides immediate energy during short-duration, high-intensity activities. It uses stored ATP and phosphocreatine (PCr) to rapidly regenerate ATP.
Think about a sprint, vertical jump, medicine ball throw, or your golf swing. These movements require the ability to produce high levels of force and power in a short amount of time.
2. Glycolytic System
The glycolytic system breaks down glucose and stored muscle glycogen to produce ATP. It becomes increasingly important as exercise intensity and duration increase.
It contributes during repeated high-intensity efforts, demanding intervals, and sustained muscular work.
3. Oxidative System
The oxidative system uses oxygen to produce ATP from carbohydrates and fats. It supports prolonged, lower-intensity activity and plays an important role in recovery between higher-intensity efforts.
Walking, cycling, and longer-duration activity are examples of where this system contributes significantly.
How Do These Energy Systems Apply to Golf?
The Golf Swing: ATP-PC System
The golf swing is an explosive movement requiring the body to generate force quickly and coordinate multiple segments to produce rotational speed and clubhead speed.
These demands rely heavily on the ATP-PC system.
This is one reason why developing strength and power should be an important part of a golfer’s physical preparation. Exercises such as medicine ball rotational throws, jumps, and other explosive movements can help develop the ability to produce force quickly.
Between Swings: Oxidative System
A golf swing might last only a couple of seconds, but golfers spend several minutes walking, waiting, and preparing for their next shot.
During this time, the oxidative system supports ongoing activity and recovery. One important role is helping restore phosphocreatine levels after explosive efforts so energy reserves are available for the next swing.
This is why aerobic capacity matters in golf. It’s not just about walking 18 holes without getting tired. It’s also about supporting recovery and maintaining performance throughout the round.
Repeated Efforts: Glycolytic System
The glycolytic system also contributes to golf performance, particularly during more demanding physical activity and higher-intensity efforts.
Although it isn’t the primary energy system for an individual golf swing, it plays a role in the body’s overall ability to produce energy. All three systems contribute to meeting the physical demands of golf.
Why Recovery and Fatigue Matter
Have you ever felt like your swing was different on the back nine compared to the front nine?
Maybe your body feels heavier, your rotation doesn’t feel as smooth, or you’re having a harder time maintaining focus.
Physical fatigue can influence force production, movement quality, and the ability to repeat high-quality efforts. Mental fatigue can also affect concentration and decision-making.
This is where physical preparation becomes important. Developing strength, power, and aerobic capacity can help golfers better manage the physical demands of an entire round.
The goal isn’t to turn golfers into endurance athletes. It’s to build the physical capacity to produce power, recover between efforts, and maintain performance for 18 holes.
How Should Golfers Train?
Understanding the energy systems is great, but what should golfers actually do with this information?
A well-rounded golf performance program, like the GPC Performance System, develops several physical qualities rather than focus on one energy system exclusively.
ATP-PC: Develop Power
- Medicine ball rotational throws.
- Explosive jumps.
- Short acceleration sprints.
- High-intensity strength efforts with adequate recovery.
The goal is to produce force quickly while maintaining movement quality. These are programmed as low repetitions with maximal effort. This is the style of exercise you will see in the Power Phase coming in late March, early April, after our Maximal Strength Phase.
Glycolytic: Develop High-Intensity Capacity
- Structured interval training.
- Repeated higher-intensity efforts.
- Controlled conditioning circuits- like you see in the GPC Workouts!
These efforts are programmed carefully so they don’t interfere with strength and power development.
Oxidative: Develop Aerobic Capacity
- Walking.
- Cycling.
- Incline treadmill work.
- Longer-duration, lower-intensity conditioning.
Improving aerobic capacity can help support recovery between explosive efforts and maintain performance throughout a round.
Nutrition and Hydration: Fueling 18 Holes
We can’t talk energy systems without talking about nutrition.
Carbohydrates provide glucose for energy production and help maintain muscle glycogen stores. For golfers playing four to five hours, proper fueling and hydration are important.
A few things to consider:
- Before your round: Eat a balanced meal containing carbohydrates and protein. Think of your classic breakfast: 3 eggs, oatmeal and a banana!
- During your round: Bring easily digestible carbohydrate and protein sources to maintain energy availability. I’ll have an article about what exactly to eat and when to eat it as next season gets closer!
- Hydration: Drink consistently throughout the round, especially in hot and humid conditions.
- After your round: Prioritize carbohydrates, protein, and fluids to support recovery. A nice big steak and a potato with some veggies should do the trick!
The goal is to avoid starting a round under-fueled and running out of energy before reaching the 18th green. If done correctly your system will have plenty of sources to generate ATP from for energy production!
If you do not fuel properly, your body will find other ways to create ATP to keep you going. This is called Gluconeogenesis. Where the body determines it needs energy and it looks for Carbs first then fat, but neither are available, it will pull proteins directly from the muscle tissue. This is why in season it is difficult for golfers to maintain strength and body weight. It is pivotal that a golfer properly fuels!!
The Takeaways:
Golf requires more than the ability to produce power. It requires the ability to repeatedly produce explosive movements, recover between efforts, and maintain performance over several hours.
The three energy systems work together to meet these demands.
Here are five key takeaways:
- Power matters. The golf swing requires rapid energy production and the ability to generate force quickly.
- Aerobic capacity matters. It’s not just about walking 18 holes; it’s also about supporting recovery between explosive efforts.
- All three energy systems work together. Their contributions change depending on the demands placed on the body.
- Fatigue matters. Maintaining physical and mental performance throughout a round requires preparation.
- Train with purpose. Our program develops strength, power, mobility, and conditioning for humans that transfers to golf!
Final Thoughts
Being physically prepared for golf means more than simply hitting the ball farther.
Yes, we want to develop strength, rotational power, and clubhead speed. But we also want the physical capacity to recover between swings, maintain movement quality, and perform consistently throughout an entire round.
The better we understand how the body produces and uses energy, the better decisions we can make about how we train, recover, and fuel ourselves. Or have the knowledge to question if your current program is attacking all of these systems.
The goal isn’t just to have your best swing on the first tee. It’s to have the physical capacity to perform your best from the first swing to the final putt.
If you feel like your current workout program does not provide any of this for you let us know! We have a virtual program that you can follow that is backed by science to improve all of these systems as well as how your body moves from a mobility/stability, strength/power perspective for your golf game!!!
