How Does Caffeine Affect Your Workouts?

Athletes typically consume caffeine in the form of coffee, energy drinks, gels, or dietary supplements. It is a substance that can be found in many different products. To what extent are you aware of it?

Caffeine has been a part of human culture from the dawn of time, and there is little danger to health from this haabit. From an ethical perspective, the substance is entirely lawful.

Mechanism of Action of Caffeine

Our body contains adenosine receptors, which, when occupied, carry out processes like regulating sleep-wake cycles and inhibiting nerve excitation, which results in a sedative effect. Caffeine will compete with adenosine for these receptors when consumed, occupying them with caffeine rather than adenosine. Due to caffeine’s stimulation of our central nervous system, which results in the effects we will discuss next, this causes very noticeable changes.

Caffeine’s Effects on the Body

  • stimulates the brain and spinal cord
  • increases the release of norepinephrine and adrenaline, two catecholamines.
  • raises heart rate and blood pressure.
  • increases the production of urine.
  • decrease in fatigue.
  • reduces the feeling of perceived effort.
  • boosts the oxidation of fat.
  • improves athletic performance.
  • raises the level of mental activity

The Optimal Quantity of Caffeine: Posology

A dosage of 3.2 to 4.5 mg/bodyweight kg would be ideal. This enhances performance in resistance exercises that are longer and more intense as well as those that are shorter (up to five minutes).

Since the plasma concentration peak would be reached in about an hour, the majority of studies suggest that caffeine should be taken at rest, one hour before beginning the activity.

Caffeine intolerance

Most people are aware that consuming excessive amounts of caffeine daily can lead to tolerance, requiring higher and more doses to produce the desired effects. This makes sense because our bodies will produce more adenosine receptors, which means we’ll require more caffeine to fill them all.

That is why we employ various strategies, such as temporarily stopping the substance’s consumption, to eradicate this tolerance. As a result, the adenosine receptors are reset, restoring our body’s high sensitivity to that chemical.

Although we can also employ other highly recommended strategies, the most general recommendations establish a two to three-week break for every three months of taking. To avoid taking shots for the remainder of the week, one could, for instance, consume caffeine two to four days a week and time the shots with the most strenuous workouts.

Caffeine withdrawal syndrome is another crucial issue. A drastic reduction in your intake can result in symptoms like headache, lethargy, and low mood. Therefore, we should gradually cut back on the shots rather than stop them abruptly if we experience these symptoms when we stop drinking caffeine.

Caffeine’s Effects on Performance

On Prolonged Aerobic Workouts

The majority of studies demonstrate enhanced performance in resistance exercises where fatigue is postponed for 30 to 60 minutes following caffeine administration. When exercising at 80% of VO2 max, scientists saw a 13-minute increase in exercise duration following the administration of a 5-milligram/kg dose of caffeine.

Regarding Brief Anaerobic Workouts

Researchers looking at 100-meter freestyle swimmers in 2002 found that caffeine consumption increased swimmers’ times by roughly one second. The inexperienced people did not get any better. Additionally, it has been noted that caffeine increases the Wingate Test’s maximum potency (6 seconds).

About Strength

To fulfill the functional requirements of their role in movement or posture maintenance, muscles change the composition of their fibrils. A high degree of heterogeneity in the topological distribution of the fibers within each muscle or muscle fascicle is another indication of this.

Caffeine and Creatine interactions

The study from 1996 that started this whole controversy about creatine and caffeine interference found that while the group that drank only creatine improved their performance, the group that drank both did not.

For many years, theories have been put forth in an attempt to explain why this interference happens.

Some claimed that because caffeine resembles adenosine and ATP is adenosine triphosphate, it would block adenosine receptors and cause interference. Some explain it by saying that because caffeine tends to decrease intramuscular water content and creatine tends to increase it, the two have opposing effects on water regulation.

Conversely, some contended that while creatine increases muscle relaxation time (TRM), caffeine decreases it. And lastly, some believe that these interferences are caused by the gastrointestinal issues that these two drugs may cause.

As a result, we are unable to guarantee that caffeine and creatine do not interact today. A variety of recently published studies indeed demonstrate the lack of this interaction. Therefore, more research is required to make sure that these two substances do not interact with one another.
