Improving Army Fitness Test (AFT) Performance: Will Creatine Supplementation Help?

First, a disclaimer: We're not doctors and we don't play them on TV -- always use common sense and seek second and third opinions from experts when considering supplements. Always buy from a reputable source.

If you're serious about optimizing your performance on the Army Fitness Test (AFT), then you've likely heard about creatine supplementation. As one of the most researched and proven supplements available, creatine has earned its reputation as an effective performance enhancer for both strength and power activities. But how exactly can it benefit service members preparing for the AFT, and what's the most effective way to use it?

This comprehensive guide breaks down everything you need to know about creatine supplementation specifically for military personnel, helping you make an informed decision about whether this supplement is right for your AFT preparation.

What Is Creatine and How Does It Work?

Creatine is a naturally occurring compound found in muscle cells that plays a crucial role in energy production during high-intensity, short-duration activities. Your body produces about 1-2 grams of creatine daily, primarily in the liver, kidneys, and pancreas. Additional creatine comes from dietary sources like meat and fish, with beef, pork, and salmon containing approximately 2-5 grams per pound.

The Science Behind Creatine

At its core, creatine functions as part of the phosphocreatine energy system, which is your body's fastest way to regenerate ATP (adenosine triphosphate), the primary energy currency of your cells. During intense exercise like maximum deadlifts or sprint-drag-carry, your muscles rapidly use ATP. When this happens, creatine phosphate donates its phosphate group to ADP (adenosine diphosphate) to quickly regenerate ATP, allowing continued high-intensity effort.

By supplementing with creatine, you increase your muscle's phosphocreatine stores by approximately 10-40%, enhancing your capacity to regenerate ATP during high-intensity exercise. This translates to:

1. Increased power output during short, explosive activities

2. Enhanced strength for maximal efforts

3. Improved endurance during repeated high-intensity efforts

4. Faster recovery between sets or efforts

How Creatine Can Benefit Your AFT Performance

The Army Fitness Test consists of five events that measure different aspects of military readiness. Let's break down how creatine supplementation can specifically benefit each component:

1. 3-Repetition Maximum Deadlift (MDL)

The deadlift event directly tests your lower body and grip strength by requiring three consecutive repetitions at maximum weight.

Creatine Benefits:

• Increases phosphocreatine availability for ATP regeneration during maximal strength efforts

• Enhances neuromuscular recruitment, potentially allowing you to activate more muscle fibers

• May allow for 5-15% improvements in maximum strength performance

• Supports recovery between the three repetitions, helping maintain form and power on the final rep

2. Hand-Release Push-Up with Arm Extension (HRP)

This event measures upper body endurance over a 2-minute period, testing your capacity to repeatedly generate force with your chest, shoulders, and triceps.

Creatine Benefits:

• Improves performance in repeated, high-intensity muscle contractions

• Delays fatigue during high-rep sets

• Enhances recovery between repetitions

• Particularly beneficial for the first 30-60 seconds when maximum output is possible

3. Sprint-Drag-Carry (SDC)

This multi-element event combines sprinting, dragging, lateral movement, and weighted carries—all activities that heavily tax your anaerobic energy systems.

Creatine Benefits:

• Significantly enhances performance in short sprints (up to 30% improvement in some studies)

• Improves power output during the sled drag portion

• Helps maintain high effort across all five shuttles

• Potentially reduces the performance decline between the first and last shuttle

4. Plank

The plank tests your core endurance and stability while maintaining proper body alignment.

Creatine Benefits:

• May enhance isometric muscular endurance

• Could help maintain proper form during extended holds

• Provides additional benefits when combined with core-specific training

5. 2-Mile Run

The 2-mile run assesses aerobic endurance and cardiovascular fitness.

Creatine Benefits:

• Mixed evidence for endurance performance benefits

• Some research suggests potential benefits for interval-based training to improve run times

• May indirectly benefit through enhanced training capacity in preparation phases

Total AFT Performance

Beyond individual events, creatine offers holistic benefits for your AFT preparation:

• Enhanced training capacity: Train harder and recover faster between sessions

• Improved body composition: Potential increases in lean mass without significant fat gain

• Injury prevention: Some evidence suggests reduced risk of muscle strains and injuries

• Cognitive function: Emerging research shows potential benefits for mental performance under stress

• Recovery enhancement: Faster recovery between training sessions

The Military Perspective on Creatine

Creatine usage is widespread among military personnel. Surveys of military populations consistently show that approximately 27% of service members who use supplements choose creatine. Despite this popularity, there's been debate about its appropriateness for military fitness.

Some military fitness experts have historically expressed concern that creatine supplementation might hinder endurance performance required for military activities. Former Navy SEAL Stew Smith has written that creatine's benefits for strength and power might come at the expense of endurance capabilities in military settings.

However, recent scientific consensus supports creatine's overall benefits for military fitness. The International Society of Sports Nutrition (ISSN) has stated that creatine monohydrate is "the most effective ergogenic nutritional supplement currently available to athletes in terms of increasing high-intensity exercise capacity and lean body mass during training."

Current research indicates that:

1. Creatine supplementation does not impair endurance performance

2. The strength and power benefits outweigh any potential concerns

3. Proper dosing and timing can optimize benefits across multiple fitness domains

4. Water weight gain typically stabilizes after the initial loading phase

The key for military personnel is finding the right protocol that enhances AFT-specific elements without compromising overall military readiness.

Optimal Creatine Protocol for AFT Preparation

Based on current scientific consensus and military-specific considerations, here's the optimal creatine supplementation protocol for AFT preparation:

Form Selection

Recommendation: Creatine Monohydrate

Despite numerous alternative forms on the market (ethyl ester, HCL, buffered, etc.), creatine monohydrate remains the most well-researched, effective, and cost-efficient form available. Don't be swayed by marketing claims—stick with what science consistently supports.

If you're concerned about digestion issues, consider micronized creatine monohydrate, which has a finer consistency and may dissolve more easily, but maintains the same effectiveness.

Dosing Strategies

A few caveats -- not everyone weighs 185 lbs (which is likely the average weight of participants in creatine studies). So it follows naturally that some people may need a higher dose to maximize effectiveness. Test it out. Start with moderation. If you tolerate creatine well, you may choose to explore daily doses greater than 5 grams.

Option 1: Loading Protocol (Fastest Results)

• Loading Phase (5-7 days): 20-25g daily, divided into 4-5 doses of 5g each

• Maintenance Phase: 3-5g daily in a single dose

Option 2: Gradual Protocol (Fewer Side Effects)

• Daily Dose: 3-5g daily consistently

• Timeline: Takes approximately 3-4 weeks to reach full saturation (vs. 5-7 days with loading)

For military personnel preparing for an upcoming AFT, the choice often depends on your timeline:

• If your test is 4+ weeks away: Consider the gradual protocol to minimize potential digestive discomfort

• If your test is within 2 weeks: The loading protocol may provide more immediate benefits

Timing Considerations

Daily Timing:

• Take with meals to enhance absorption

• Consume with carbohydrates to improve creatine uptake (approximately 30-50g carbs)

• Consistent timing is more important than specific time of day

Training Timing:

• Post-workout may offer slight advantages for absorption due to increased blood flow to muscles

• However, total daily consumption is more important than specific timing

• Consistency is key—find a schedule that works for your routine

Cycling Protocol

Unlike some supplements, creatine does not require cycling for effectiveness or safety. Long-term studies show consistent benefits with daily use for years without adverse effects. The decision to cycle off should be based on:

1. Your training blocks and periodization

2. Specific AFT preparation phases

3. Personal response and needs

For most service members, maintaining consistent creatine levels year-round provides the best ongoing benefits for training and performance.

Creatine Safety and Side Effects for Military Personnel

The safety profile of creatine is extremely well-established through hundreds of studies across diverse populations. When used as directed, creatine is considered safe for healthy individuals, including military personnel.

Common Side Effects

1. Water Retention: The most consistently reported effect is an initial increase in body weight (1-3 pounds) due to water retention in the muscles. This typically stabilizes after the loading phase and is not associated with bloating or water retention outside the muscles.

2. Digestive Discomfort: Some individuals experience stomach cramping or diarrhea, particularly during the loading phase or when taking large doses at once. This can be minimized by:

   • Using the gradual protocol instead of loading

   • Dividing doses throughout the day

   • Taking with meals

   • Ensuring adequate hydration

3. Muscle Cramping: Despite anecdotal reports, research does not support any link between creatine and muscle cramping. In fact, some studies suggest potential protective effects against exercise-induced cramping.

Unfounded Concerns

Several myths about creatine persist despite scientific evidence to the contrary:

1. Kidney Damage: Multiple studies in healthy individuals show no adverse effects on kidney function with recommended doses. However, those with pre-existing kidney conditions should consult a medical professional.

2. Dehydration Risk: Research indicates creatine may actually have protective effects against dehydration and heat illness by increasing intracellular water retention.

3. Hair Loss: No scientific evidence supports the claim that creatine causes hair loss.

4. Hormonal Effects: Creatine is not a hormone and does not function like anabolic steroids. It will not cause hormonal imbalances when used as directed.

Military-Specific Considerations

For service members, a few additional considerations apply:

1. Hydration Management: Proper hydration becomes even more important during field exercises or deployments when using creatine.

2. Body Weight Changes: Be aware of the initial water weight gain if you're near weight requirements for your service branch.

3. Long-Term Sustainability: Consider whether you can maintain consistent supplementation during deployments or field training.

4. Medical Screenings: While creatine is not on prohibited supplements lists, be prepared to disclose usage during medical screenings.

Combining Creatine with Other Supplements for AFT Optimization

Common Questions About Creatine and the AFT

Will creatine make me fail the 2-mile run?

No, research does not support the notion that creatine supplementation impairs endurance performance. While the initial water weight gain (1-3 pounds) might theoretically affect run times slightly, this effect is typically outweighed by the training benefits creatine provides. Additionally, some studies suggest creatine may actually improve high-intensity interval training, which can enhance 2-mile run performance when properly implemented.

Will the water weight from creatine affect my military weight requirements?

Initial water retention from creatine supplementation (1-3 pounds) could potentially impact those who are borderline on weight standards. However, this weight gain is intramuscular water, not fat, and typically stabilizes after the initial loading phase. If you're concerned about weight requirements, consider:

• Starting creatine supplementation well before any official weigh-ins

• Using the gradual protocol rather than loading to minimize initial weight fluctuations

• Monitoring weight regularly and adjusting overall nutrition if needed

Do I need to cycle off creatine before my AFT?

No, cycling off creatine before your AFT would actually be counterproductive. The performance benefits of creatine are directly related to maintaining saturated creatine stores in your muscles. Stopping supplementation would gradually reduce these stores over 4-6 weeks, potentially decreasing performance. For optimal AFT results, maintain your regular creatine protocol right through test day.

Can women benefit from creatine supplementation for the AFT?

Absolutely. While much early creatine research focused on male subjects, more recent studies show that women receive similar performance benefits from creatine supplementation. In fact, some research suggests that female service members may see even greater relative improvements in upper body strength events like the HRP. Dosing recommendations remain the same, though smaller individuals may opt for the lower end of the dosing range (3g daily maintenance rather than 5g).

Is creatine allowed in the military?

Yes, creatine is not a prohibited substance in the military. It's classified as a dietary supplement and is widely used among service members. The Department of Defense's Human Performance Resource Center (HPRC) acknowledges creatine as one of the few supplements with strong scientific support for performance benefits. Always verify current regulations with your specific branch and unit.

Will creatine help me pass the AFT if I haven't been training?

No supplement, including creatine, can replace proper training. Creatine enhances the results of your training efforts but doesn't create fitness on its own. Consistent, structured training specific to AFT events remains the foundation of successful performance. Creatine works best when combined with appropriate training, nutrition, and recovery strategies.

Conclusion: Is Creatine Right for Your AFT Preparation?

Based on extensive scientific evidence, creatine supplementation offers significant potential benefits for service members preparing for the Army Fitness Test. Its strongest effects align well with the demands of the MDL, HRP, and SDC events, with potential secondary benefits for overall training capacity and recovery.

When deciding whether creatine is right for you, consider:

1. Your current fitness level and AFT readiness

2. Specific events where you need the most improvement

3. Your typical diet and whether you already consume creatine-rich foods

4. Any pre-existing medical conditions (consult healthcare provider if unsure)

5. Your ability to maintain consistent supplementation

For most healthy service members, creatine monohydrate represents a safe, effective, and evidence-based addition to a comprehensive AFT preparation strategy. When combined with proper training, nutrition, and recovery practices, it may provide the edge needed to achieve your best possible performance.
