Caffeine is a widely available stimulant that many people consume to increase alertness and energy levels. It is present in coffee, tea, chocolate, cocoa, energy drinks, and soda. While caffeine can enhance athletic performance and physical endurance, its impact on muscle growth and burning is more complex. Some believe that caffeine may stunt muscle growth, while others suggest that it can help muscles burn fat more efficiently, leading to increased endurance during workouts. Research indicates that caffeine can positively influence muscle contraction and reaction rate, but its direct impact on muscle building is minimal. Understanding the effects of caffeine on muscle burning and growth requires further investigation.

What You'll Learn
Caffeine can increase endurance and strength
Caffeine is a widely available stimulant that can increase endurance and strength. It is commonly used as an ergogenic aid to improve exercise performance, particularly in endurance-type exercises. Research has shown that caffeine can increase muscular endurance, movement velocity, muscular strength, sprinting, jumping, and throwing performance. The performance-enhancing effects of caffeine are supported by various studies, including a January 2019 paper in Sports Medicine and a September 2016 paper in the European Journal of Sport Science.
The positive effects of caffeine on endurance and strength can be attributed to several factors. Firstly, caffeine increases thermogenesis or heat production, which raises body temperature and may help burn more calories. Secondly, caffeine spares muscle carb stores by increasing fat burning, thereby enhancing endurance performance. Additionally, caffeine can reduce the perception of pain and anxiety associated with strenuous exercise, which may contribute to improved endurance and strength.
The recommended dose of caffeine for enhancing endurance and strength is typically between 3 to 6 mg per kg of body weight. However, the optimal dose may vary depending on individual factors such as gender, age, body mass, and overall health. It is important to note that very high doses of caffeine (e.g., 9 mg/kg) are associated with a higher risk of side effects and may not be necessary to achieve the desired performance enhancement.
While caffeine can have performance-enhancing effects, it is important to consider potential side effects and individual responses. Some people may experience negative side effects such as increased anxiety, heart palpitations, insomnia, and hindered sleep quality. Additionally, excessive caffeine consumption can cause muscle twitching and interfere with calcium absorption, contributing to bone thinning. Therefore, it is advisable to be cautious and aware of how your body responds to caffeine before incorporating it into your routine.

It can help reduce muscle soreness
Caffeine is a widely available central nervous system stimulant that affects the body in numerous ways. It is often referred to as a nutritional ergogenic aid, meaning that it can enhance physical performance, but it has no nutritional value by itself. The average caffeine consumption for Americans is about 2 cups of coffee per day, but you can also find caffeine in tea, chocolate, cocoa, energy drinks, and soda.
Caffeine has been shown to assist with blocking pain associated with Delayed Onset Muscle Soreness (DOMS). A study published by the Department of Kinesiology at the University of Illinois found that people who drank caffeine before a workout experienced less anxiety associated with strenuous exercise, which may account for their lower perception of pain. This lower perception of pain can be attributed to caffeine's ability to dull the sensation of muscle burn during intense exercise.
Additionally, a study conducted by the University of Georgia found that moderate doses of caffeine, roughly equivalent to two cups of coffee, cut post-workout muscle pain by up to 48% in a small sample of volunteers. This finding may be particularly relevant to people new to exercise, as they tend to experience the most soreness. Furthermore, caffeine has been shown to be more effective in relieving post-workout muscle pain than several commonly used drugs, such as naproxen, aspirin, and ibuprofen.
However, it is important to note that the effects of caffeine can vary from person to person, and excessive caffeine consumption can lead to side effects such as jitteriness, heart palpitations, and sleep disturbances. Therefore, it is recommended to use caution when using caffeine before a workout and to know how your body will respond to it.

Caffeine may cause muscles to twitch in large amounts
Caffeine is a widely available central nervous system stimulant that affects the body in numerous ways. It is often referred to as a nutritional ergogenic aid, meaning that it can enhance physical performance, but it has no nutritional value by itself. The effects of caffeine can vary from person to person, and factors such as age, body mass, and overall health can determine one's tolerance to it.
While caffeine does have performance-enhancing effects for some athletes, it is important to note that consuming large amounts of caffeine may cause muscle twitching. Caffeine can trigger muscle twitches or spasms in various parts of the body. This occurs due to the increased mobilization of calcium ions under the influence of caffeine, which slows the rate of muscle relaxation. Additionally, muscles exposed to caffeine show a reduced ability to restore homeostasis, which may be associated with increased damage caused by caffeine-induced high muscle work intensity.
The link between caffeine and muscle twitching is supported by various studies and reports. A renowned neurologist, Dr. Vikram Sharma, affirms the connection, stating that caffeine and twitching muscles go hand in hand. Research has also shown that caffeine can affect muscle activation time, contraction time, and maximal displacement in athletes who regularly consume caffeine. Furthermore, a study on laboratory animals by Brigham Young University in 2015 indicated a catabolic (tearing-down) effect of caffeine, although this effect was found to be temporary.
It is worth noting that muscle twitching can be caused by various factors, including stress, anxiety, exhaustion, sleep deprivation, and excessive exercise. Additionally, dehydration and inadequate electrolyte levels can contribute to muscle twitches and cramps. While caffeine may not be the sole cause of muscle twitching, excessive consumption can increase the likelihood of experiencing these symptoms.

It can help muscles burn fat more quickly
Caffeine is a stimulant that affects the body in numerous ways. It is a widely available plant product and is one of the most commonly used stimulants in the world. The average American consumes about 2 cups of coffee per day, but caffeine can also be found in tea, chocolate, cocoa, energy drinks, and soda.
Caffeine has many performance-enhancing effects. It increases endurance and strength, and can help muscles burn fat more quickly. Muscles use glycogen, a stored form of glucose, for energy. When glycogen stores run out, muscles get weaker and less efficient, leading to exhaustion. However, muscles can also burn fat, and when they do, they don't tire as easily. Caffeine can shift muscles to burn fat more quickly, which can preserve glycogen stores and give muscles more time before they wear out. This leads to a longer and less painful workout.
Research has shown that caffeine can prevent fatigue during repeated cycling sprints in fit men. Another study found that ingesting coffee with 3 milligrams of caffeine per kilogram of body weight can make runners faster. Compared to decaffeinated coffee, drinking coffee caused a 1.3% decrease in the time needed for men to complete a 1.6-kilometer race.
Caffeine can also have a positive effect on delayed-onset muscle soreness, in addition to increasing performance. This means that caffeine has both immediate and delayed effects on the body. It is important to note that the effects of caffeine can vary from person to person, and excessive caffeine consumption can have negative side effects.

Caffeine does not dehydrate you unless you drink over 500-600 milligrams a day
Caffeine is a diuretic, which means it can increase urination frequency. However, it takes a large amount—more than 500-600 milligrams per day, or the equivalent of 5-7 cups of coffee—to have a significant dehydrating effect. Below this level, your body does not lose more fluid than the beverage itself provides. For context, an 8-ounce cup of coffee has about 100 milligrams of caffeine, and an energy drink can have up to 242 milligrams per serving.
While caffeine may cause a slightly higher urine output over 24 hours when compared to water, this effect is mild and does not impact hydration levels. In fact, drinking a cup of coffee can be hydrating and help you meet your daily fluid needs. Regular coffee drinkers may experience even less of caffeine's diuretic effects, as their bodies can build up a tolerance over time.
It's important to note that other factors, such as age, body mass, and overall health, can also influence your tolerance to caffeine. Additionally, if you have stomach issues like acid reflux or ulcers, it's advisable to consult a doctor before consuming caffeine, as it increases stomach acid and may cause heartburn or an upset stomach.
Although caffeine does not directly burn muscle, it can have both positive and negative effects on muscle-related processes. For example, caffeine can increase endurance and strength, but it may also interfere with calcium absorption, contributing to bone thinning if consumed in large amounts. Furthermore, while it doesn't impact muscle growth, caffeine has been shown to positively influence delayed-onset muscle soreness.
