Intra-Workout EAA and Electrolyte Supplementation for Endurance and Hydration

Many athletes prefer endurance-focused workouts for their training regimen.  Whether the athlete runs, swims, hikes, cycles or does HIIT workouts, every cardio workout is focused on improving endurance.  Dehydration and fatigue are real factors to consider when engaging in cardio-specific activities.  Injury risk is heightened when the athlete is fatigued, and maintaining electrolyte balance is crucial for sustained activity.  Supplementing with Essential Amino Acids and electrolytes is crucial for improved performance and reduced fatigue.

Supplements for Endurance Activities

When actively partaking in cardio, EAAs and electrolytes will be of great benefit.  If rapid fatigue sets in, the athlete has a higher likelihood for injury.  If dehydrated, the athlete may need to stop the exercise entirely.  To understand how EAAs and electrolytes work against these negative outcomes, first one must know what these supplements are.

Essential Amino Acids

Essential Amino Acids are the building blocks for muscle.  When muscle is broken down during exercise, the body must use EAAs to repair and replace this worn tissue.  The body cannot produce EAAs on its own.  EAAs must be consumed to be available for the body to utilize.  EAAs are found in animal foods, but optimal muscle synthesis (growth and repair) can only be achieved via a balanced EAA supplement.

Electrolytes

Electrolytes are electrically charged molecules that regulate the body’s fluid levels.  These are lost through sweat.  When electrolytes are lost through sweat and not replenished, dehydration is the result.  Water is often enough to replenish the body’s store of electrolytes, however, it may not be entirely sufficient when the athlete is in a tough cardio session.  In this case, electrolyte supplementation is key. 

Combined 

Combining and consuming EAAs and electrolytes intra-workout is the optimal method of supplementation.  With both, the athlete’s muscles are properly fed and his fluid levels are balanced.  Muscle synthesis will be sustained, fatigue will be combatted and one will have a balanced level of electrolytes.  Enhanced endurance sessions will be the result of proper supplementation.

Sustaining Muscle Synthesis

Muscle synthesis is the process of repairing torn muscle tissue and making it larger and stronger.  This process is essential for the endurance athlete as muscle is broken down during long training sessions.  Without muscle synthesis, the athlete will be unable to perform at his highest capacity.  The body would be repairing slowly, thereby hindering performance.  With EAAs and electrolytes, improved muscle synthesis can be achieved. 

Essential Amino Acids

EAAs are the only nutrients that can stimulate increased muscle synthesis.  When taking EAAs during an endurance activity, the athlete’s muscles are continuously supplied with what is needed for recovery.  If muscle synthesis is not physiologically encouraged, the athlete will not be able to push as hard during each session.  His muscles will be attempting to heal instead of being at full capacity.  This full capacity can be reached more efficiently when supplementing with EAAs.

Electrolytes

During an endurance-centric workout, much of the body’s electrolytes will be lost through sweat.  When electrolytes are being spent without replenishment, the athlete’s fluid levels will be imbalanced.  Imbalanced fluid levels affect muscle cells, blunting the muscle synthesis process.  Additionally, key electrolytes are essential for proper muscle contraction.  If muscle contraction is being hindered by dehydration, fatigue and cramps will result.  

Intra-Workout Benefits

Supplementing with EAAs and electrolytes intra-workout is necessary to stimulate muscle synthesis.  With EAAs and electrolytes, the body will have enough fluid to adequately supply the amino acids to each muscle.  Muscle synthesis will be stimulated, leading to more endurance, less perceived exertion and no effects of dehydration.  Tomorrow’s session is improved when muscle synthesis is activated today.

Combatting Fatigue

Fatigue is a component of any workout routine, and to a certain extent, it is inevitable.  However, fatigue can be postponed.  Fatigue setting in during an endurance session usually marks the end of the workout, as energy dramatically drops and injury risk rises.  With proper supplementation, fatigue can be successfully mitigated.

Essential Amino Acids

EAAs help to battle fatigue by supplying the athlete’s muscles with what he needs for repair and growth.  Muscles fatigue when ATP is not present enough during athletic performance.  EAAs support ATP production and accelerates muscle synthesis, both of which give muscles an increased ability to work.

Electrolytes

When electrolytes diminish during cardio, overall strength output will weaken.  Fatigue will then set in, marking the end of the workout.  If electrolytes are supplemented, cardiovascular output will be maintained, therefore delaying fatigue.  Muscles need electrolytes to efficiently and consistently contract.  If smooth contraction is unavailable, fatigue will begin.  Supplementing with balanced electrolytes will encourage muscle contraction, as well as supporting ATP utilization.  With a more efficient use of ATP, the athlete will have more energy to spend throughout the cardio session.

Intra-Workout Benefits

Taking EAAs and electrolytes during a workout will give the athlete’s body what is required to stave off fatigue.  With fatigue leading to potential injury and discouraging the athlete from future workouts, it is imperative that proper supplements be utilized.  EAAs will support ATP production and encourage muscle synthesis, while electrolytes help muscles contract and support cardiovascular output.  With fatigue minimized, the athlete can focus on breaking plateaus.

Maintaining Electrolyte Balance

Electrolytes are lost through sweat and must be replenished.  Water is not always sufficient for true hydration, especially during and after intense cardio sessions.  This being the case, it can be tricky to maintain a proper electrolyte balance.  Not only will supplementing with electrolytes benefit this cause, but so too will EAAs.  Both are necessary to keep internal fluid levels consistent.

Essential Amino Acids

Many may not consider EAAs to be directly beneficial for electrolyte levels.  Electrolytes can be lost through muscle breakdown during exercise.  EAAs can stabilize electrolyte levels by reducing muscle protein breakdown.  EAAs also improve cellular hydration, which indirectly supports electrolyte levels.

Electrolytes

Naturally, the best way to maintain a healthy electrolyte balance is to supplement with electrolytes.  However, not every electrolyte product is made the same.  Some only have two electrolytes.  The most effective supplements contain a full profile of key electrolytes (like our Muscle Synthesis Activator).  Supplementing with multiple key electrolytes will replace what was lost during exercise, benefiting performance and recovery. 

Intra-Workout Benefits

Many athletes will consume an electrolyte supplement after a workout to replace what was lost through sweat.  This should be done, but electrolyte supplements are also essential for intra-workout consumption.  If only taking electrolytes post-workout, the athlete will be unable to accommodate for the poor training quality that resulted from an avoidable, dehydrated fatigue.  Preserving performance and delaying fatigue will only occur if electrolytes are supplemented.

Supplementation Strategies

Our Muscle Synthesis Activator comes with a patented blend of all nine EAAs, as well as five perfectly balanced key electrolytes.  It matters if an athlete supplements with electrolytes and EAAs (like our MSA), and it matters when he consumes them.  These supplements will benefit performance when taken pre-, intra- and post-workout.  Timing is crucial to achieve optimal performance.

Pre-Workout

Our MSA works best when one to two scoops is taken within 20 to 30 minutes of one’s training window.  This allows for the body to completely absorb the EAAs and offers a chance for fluid levels to balance.  The athlete will notice more energy at the beginning of his workout, with that energy being sustained throughout.  This is supported by intra-workout supplementation.

Intra-Workout

Taking one scoop intra-workout will keep the body fueled with EAAs and electrolytes.  This will result in less perceived exertion, delayed fatigue onset and more energy.  A balanced fluid level in the athlete’s body will stave off dehydration while allowing for the EAAs to successfully reach the muscles. 

Post-Workout

Taking one to two scoops of our MSA post-workout will promote speedy recovery; post-workout is when the body needs EAAs the most.  Giving the body EAAs post-workout will provide muscles with exactly what they need for complete recovery.  When muscle synthesis is reached, the athlete will feel energized and less sore.   The electrolytes consumed post-workout will enable full hydration, thereby reducing the chance for a dehydrated fatigue.  The next workout will be met with energy and vigor when supplementing with EAAs and electrolytes.
