Sports Performance, Protein, and Recovery: Build Strength That Lasts
Sports Performance, Protein, and Recovery: Build Strength That Lasts
You do not have to compete in a sport to care about performance.
Performance can mean returning to hiking after a knee injury, rebuilding strength after physical therapy, keeping up with your children, carrying groceries, climbing stairs, or continuing to live independently. For an older adult, getting out of a chair confidently is a meaningful performance goal. For someone recovering from pain or surgery, completing a workout without causing a setback is progress.
At Health and Exercise Prescriptions®, performance is not measured by how exhausted you can make yourself. It is measured by what your body can safely do, how well it recovers, and whether your capacity improves over time.
Protein powders, amino acids, creatine, electrolytes, and recovery products may support that process. However, they cannot replace the training signal, adequate food, sleep, hydration, appropriate medical care, or an exercise plan that matches your current condition.
The goal is not to collect performance supplements. The goal is to build a body that can move, adapt, recover, and continue participating in life.
Exercise Creates the Signal—Nutrition Supports the Response
Exercise gives the body information. Resistance training tells muscles that more strength is needed. Cardiovascular training asks the heart, lungs, circulation, and mitochondria to become more efficient. Balance and mobility work teach the nervous system to control movement more confidently.
Nutrition provides the energy and raw materials needed to respond to those signals.
This is especially important during post-rehabilitation. Finishing physical therapy does not automatically restore your previous strength, endurance, or confidence. The body still needs structured, progressive loading—and enough recovery resources to adapt to it.
A 2025 network meta-analysis involving 38 randomized trials and 2,610 adults over age 50 found that combining resistance exercise with protein supplementation was more effective for several muscle and functional outcomes than protein supplementation alone. Resistance training by itself also meaningfully improved strength and physical function. The Journal of Nutrition systematic review
Another 2025 review involving older adults with sarcopenia or physical frailty found promising improvements when protein supplementation was combined with exercise, although the researchers rated the overall evidence quality as very low. Archives of Gerontology and Geriatrics review
The practical message is clear: protein may support adaptation, but it does not replace the reason for adaptation.
Protein Is a Building Material, Not a Complete Recovery Plan
Protein provides amino acids used to build and maintain muscle, enzymes, hormones, immune compounds, skin, and other tissues. Exercise increases muscle-protein breakdown and synthesis, creating an opportunity for the body to repair and remodel.
The adult Recommended Dietary Allowance for protein is 0.8 grams per kilogram of body weight per day. That is a population-level baseline designed to meet the needs of most generally healthy adults—not a personalized sports, aging, or post-rehabilitation target.
According to the National Institutes of Health Office of Dietary Supplements, athletes may require approximately 1.2 to 2.0 grams of protein per kilogram per day to support training adaptation, repair, remodeling, and protein turnover. That range should not be applied automatically to everyone.
Needs vary according to:
Age and body size
Training volume and intensity
Total calorie intake
Injury or surgical recovery
Weight-loss goals
Appetite and digestion
Kidney and liver function
Medical conditions and medications
Plant-based or mixed dietary patterns
For many clients, a practical first step is not calculating a perfect number. It is looking at whether each meal contains a meaningful protein source. Breakfast is often the weakest point, so building toward approximately 20 grams of complete protein at breakfast can be a useful starting conversation.
That might come from eggs, Greek yogurt, cottage cheese, fish, poultry, tofu, tempeh, soy foods, beans paired with complementary foods, or a well-formulated protein shake.
Protein Timing Matters Less Than Consistency
The supplement industry often promotes a narrow “anabolic window,” suggesting that a shake must be consumed immediately after exercise or the workout will be wasted. Recovery is not that fragile.
The NIH reports that consuming high-quality protein during the first few hours after exercise can support muscle-protein synthesis, but the broader recovery response can remain elevated for up to 24 hours. Total daily intake and a reasonable distribution of protein across the day are generally more important than racing to drink a shake in the locker room.
For athletes, guidance cited by the NIH suggests approximately 0.3 grams of high-quality protein per kilogram—about 20 grams for a 150-pound person—within two hours after training and then at intervals throughout the day. Older adults or people with larger bodies, higher training demands, reduced appetite, or medical considerations may need a different plan.
The goal is a repeatable rhythm: train appropriately, eat enough, spread protein through the day, and give the body time to recover.
When a Protein Powder Makes Sense
Protein powder is a convenience tool. It can help someone who struggles to eat enough protein, needs a portable post-workout option, has a reduced appetite, or is trying to make a smaller meal more nutritionally complete.
Whey protein is a complete, leucine-rich protein that is quickly digested. Casein is also complete but digests more slowly. Soy is a complete plant protein, while many other plant powders use complementary sources—such as pea and rice—to improve the essential-amino-acid profile.
A protein powder should be evaluated for:
Protein amount per serving
Essential-amino-acid content
Added sugar and total calories
Dairy, soy, or other allergens
Artificial stimulants or unnecessary blends
Digestive tolerance
Independent quality certification
Whether it actually fills a nutritional gap
Collagen deserves a separate distinction. Collagen peptides may provide targeted amino acids associated with connective tissue, but collagen is not a complete protein and should not replace the protein needed for muscle maintenance and recovery.
Complete protein supports muscle-building needs. Collagen may serve as an additional connective-tissue tool. Exercise, vitamin C, micronutrients, hydration, and recovery help create the larger repair environment.
Essential Amino Acids Versus BCAAs
All protein is made from amino acids. Nine are classified as essential because the body cannot produce enough of them and must obtain them through food or supplementation.
Branched-chain amino acids—leucine, isoleucine, and valine—are three of those nine essential amino acids. Leucine is involved in signaling muscle-protein synthesis, but turning on a building signal is not the same as supplying every material needed to complete the job.
The NIH concludes that BCAA supplements have not consistently improved exercise performance, muscle growth, or recovery beyond what can be achieved with adequate high-quality protein. A complete protein or full essential-amino-acid formula generally provides a more complete set of building blocks than isolated BCAAs.
An essential-amino-acid product may still be useful when a full meal is impractical, appetite is low, or a person has difficulty tolerating a larger protein serving. It should solve a specific problem rather than become an automatic requirement.
Creatine Has Stronger Performance Evidence
Creatine monohydrate is one of the most extensively studied sports supplements. It helps replenish phosphocreatine, which supports rapid ATP production during repeated short, intense efforts such as resistance training, sprinting, and power-based activity.
The NIH reports that creatine can improve training capacity and performance during repeated high-intensity work. Creatine monohydrate is the most widely studied form, and more expensive versions have not been shown to be superior.
A common maintenance amount studied in adults is approximately 3–5 grams per day, sometimes following a short loading phase. Loading is not required to eventually increase muscle creatine stores.
Creatine can cause an increase in body weight, often partly related to greater water stored within muscle. That should not automatically be interpreted as fat gain. Individual responses vary, and creatine is not equally helpful for every activity—its benefits are more consistent for repeated strength and power efforts than for steady-state endurance exercise.
People with kidney disease, complex medical conditions, pregnancy, medication concerns, or abnormal kidney-related laboratory results should discuss creatine with an appropriate healthcare professional before using it.
Recovery Requires More Than Protein
Muscle soreness is not the only measure of recovery, and more soreness does not prove that a workout was more effective. Recovery also involves the nervous system, connective tissue, energy stores, hydration, sleep, and the ability to perform again without declining function.
A complete recovery plan includes:
Progressive exercise matched to current capacity
Adequate calories and complete protein
Carbohydrates appropriate to training demand
Hydration and electrolytes matched to sweat loss
Consistent sleep and planned recovery days
Mobility, breathwork, massage, or restorative movement when useful
Monitoring pain, fatigue, function, and performance trends
Carbohydrates help replenish muscle glycogen, especially after longer or more demanding training. Fluids and electrolytes become more important during heat exposure, heavy sweating, endurance activity, illness, or sauna use. Sleep supports tissue repair, nervous-system recovery, learning, and the consolidation of movement skills.
If performance continues to decline despite rest, consider whether the problem could involve inadequate calories, iron deficiency, sleep apnea, thyroid dysfunction, illness, medication effects, excessive training, or another condition requiring evaluation.
Supplement Quality Matters in Sports and Recovery
Performance supplements deserve extra scrutiny. The FDA does not approve dietary supplements before they reach the market, and bodybuilding products are among the categories most vulnerable to undeclared ingredients or misleading claims.
Independent certification provides an additional level of quality assurance. The NIH identifies NSF Certified for Sport®, Informed Sport or Informed Choice, and BSCG as established certification programs that screen products for label accuracy and many prohibited substances.
Thorne currently offers several NSF Certified for Sport® options in its performance categories, including whey protein, creatine, and amino-acid products. Certification does not prove that a product is necessary or effective for every person, but it provides greater confidence in manufacturing, label accuracy, and banned-substance screening.

The HEP® Strength and Recovery Prescription
At Health and Exercise Prescriptions®, we connect exercise, nutrition, and recovery instead of treating them as separate projects.
For a post-rehabilitation client, that may mean restoring joint confidence, rebuilding strength, and increasing activity without triggering another cycle of pain. For an active adult, it may mean improving hiking, running, cycling, or recreational performance. For an older adult, it may mean stronger legs, better balance, easier stair climbing, and greater independence.
The prescription begins with an assessment of where you are now. Training is then progressed according to your health history, movement quality, tolerance, and goals. Protein and supplements are considered only after we understand what the plan is asking your body to do.
