What You'll Learn
Creatine is a well-studied supplement
Creatine supplementation has been found to be an effective ergogenic aid for resistance training and intense, short-duration, intermittent performance. It elevates skeletal muscle phosphocreatine (PCr) stores, facilitating a greater capacity for rapid ATP resynthesis and buffering hydrogen ion accumulation. This increased availability of ATP may delay the onset of fatigue, allowing athletes to sustain higher intensities for repeated efforts. Additionally, creatine enhances glycogen resynthesis and content when co-ingested with carbohydrates, providing important fuel for high-intensity aerobic exercise.
While the effects of creatine on endurance performance are less known, there is a growing body of research demonstrating potential mechanisms to support its use in enhancing endurance performance. Creatine supplementation may increase power output at the electromyography (EMG) fatigue threshold, which could have implications for endurance exercise performed at or near the maximal metabolic steady state. It also appears to be beneficial for both recreational and highly trained endurance athletes, as it increases time to exhaustion during high-intensity endurance activities.
However, it is important to note that the effects of creatine diminish as the duration of exercise increases, and it may have limited benefits for lower-intensity endurance exercises. Creatine supplementation is associated with immediate weight gain due to water retention, which may offset its positive effects in weight-bearing sports. Nonetheless, creatine has a range of potential benefits for endurance athletes, and its ability to enhance anaerobic work capacity can be advantageous in various endurance sports.

Creatine is safe for long-term use
Creatine is a well-studied supplement with proven benefits for high-intensity exercise. It is a popular and safe dietary supplement, although some people may experience bloating. Creatine is safe for long-term use, and no research has shown any long-term issues in healthy individuals.
There have been concerns about the long-term safety of creatine supplementation. However, one study found no significant differences among groups in the 54-item panel of quantitative blood and urine markers assessed. Another study found that long-term creatine supplementation does not adversely affect markers of health status in athletes undergoing intense training.
Creatine is possibly safe when taken by mouth short-term by children. Creatine 3-5 grams daily for 2-6 months has been taken safely in children 5-18 years of age. Creatine 2 grams daily for 6 months has been taken safely in children 2-5 years of age. Creatine 0.1-0.4 grams/kg daily for up-to-6 months has been taken safely in both infants and children.
Pregnant and breastfeeding women should avoid creatine due to a lack of safety information. Creatine might make mania worse in people with bipolar disorder. People with kidney disease should also avoid creatine as it may worsen their condition. Finally, people with Parkinson's disease should not take creatine as it may worsen their symptoms.

Creatine may increase muscle power and strength
Creatine is a well-studied supplement with proven benefits for high-intensity exercise. It is safe for long-term use and has many benefits for health and performance. It can help increase muscle power and strength, which can be advantageous for endurance athletes.
Research has shown that creatine supplementation can increase muscle creatine stores by 10-40%, depending on the individual and their current levels. This increase in creatine stores can lead to a higher training intensity and improved workout quality. Creatine supplementation, when combined with heavy resistance training, has been shown to enhance physical performance, fat-free mass, and muscle morphology.
One study found that creatine supplementation increased power output at the electromyography (EMG) fatigue threshold by ~20 W (14.5%) in a group of recreationally trained female participants. This could have implications for endurance exercise, as it represents the highest power output that can be sustained for an extended period without neuromuscular fatigue.
Additionally, creatine monohydrate, the most studied and proven form of creatine, may delay the onset of fatigue and allow endurance athletes to sustain higher intensities for repeated efforts. It does this by increasing the availability of ATP, which is the body's primary source of energy for intense exercise.
While creatine may increase muscle power and strength, it is important to note that the effects of creatine supplementation can vary between individuals. The benefits of creatine are more pronounced when combined with high-intensity exercises or resistance training.

Creatine can improve recovery from intense exercise
Creatine is a well-studied supplement with proven benefits for high-intensity exercise. It is safe for long-term use, with no research showing any long-term issues in healthy individuals. Creatine can improve recovery from intense exercise in several ways.
Firstly, creatine supplementation increases the availability of adenosine triphosphate (ATP), which is a crucial source of energy for muscles. By increasing ATP levels, creatine helps to delay the onset of fatigue, allowing athletes to sustain higher intensities for longer and improve their performance over time.
Secondly, creatine reduces exercise-induced muscle damage and promotes faster recovery. This is achieved through the elevation of skeletal muscle phosphocreatine (PCr) stores, which facilitate the rapid resynthesis of ATP and buffer hydrogen ion accumulation. Creatine also enhances glycogen resynthesis, which is an important fuel source for high-intensity aerobic exercise.
Additionally, creatine supplementation has been shown to increase power output at the electromyography (EMG) fatigue threshold, which is the highest power output that can be sustained for an extended period without neuromuscular fatigue. This can have significant implications for endurance exercise, as it allows athletes to perform at a higher level for a longer duration.
Furthermore, creatine has cognitive benefits, reducing mental fatigue during sustained mental effort. Maintaining concentration and decision-making abilities is crucial for optimal performance in endurance events, and creatine supplementation can help athletes stay focused and make better decisions during their races.
While creatine is generally associated with immediate weight gain due to water retention, this may not necessarily be a negative side effect, especially in non-weight-bearing sports such as cycling and swimming. Creatine's ability to enhance anaerobic work capacity and performance through repeated surges in intensity makes it beneficial for various endurance sports.

Creatine may cause weight gain
Creatine is a well-studied supplement with proven benefits for high-intensity exercise. It is safe for long-term use and has many benefits for health and performance. It can help increase muscle creatine stores, which can lead to increased muscle mass, strength, and improved brain function.
However, one of the main concerns about creatine is that it may cause weight gain. This is due to water retention, which is independent of any additional muscle gain. The weight gain is typically about 1% or more of your total body weight. For this reason, creatine is more popular among athletes in non-weight-bearing sports, such as cycling and swimming, than in running or other weight-bearing sports.
An Australian cycling study tested whether the negative effects of weight gain would outweigh the positive effects of creatine. The study found that the benefits and drawbacks were about equal. However, it is important to note that creatine has a wide range of other potential benefits, given its role in the energy supply of cells throughout the body.
While creatine may cause weight gain, it is important to consider the potential benefits it can provide. It can improve muscle power and strength, even in endurance athletes. Creatine supplementation has been shown to increase cycling power output in well-trained triathletes, leading to improved performance. It may also have cognitive benefits, reducing mental fatigue during sustained mental effort, which can be advantageous during endurance events.
Overall, while creatine may cause weight gain, it also has a range of potential benefits for health and performance that should be considered.
