Additionally, a small study of Spanish Jiu-Jitsu athletes found that consuming 3 milligrams (mg) of caffeine per kilogram (kg) of body weight before a workout increased their one and two leg vertical jump height.
A 2018 review investigated this by looking at the influence of caffeine on physical and cognitive performance. It indicated that caffeine may improve cognitive states associated with better athletic performance, such as:
One study conducted in healthy males looked at how caffeine timing affected performance in different types of exercises. It showed that consuming caffeine 1 hour before exercise improved explosive vertical jumps and isometric muscle contractions.
However, consuming caffeine 30 minutes before exercise improved isokinetic performance. Isokinetic exercises are dynamic, and while the resistance may vary, the speed stays the same. Isokinetic exercises include pushups and pullups.
High doses (9 mg per kg) may cause side effects unnecessary for performance enhancement, such as upset stomach and insomnia. Research on smaller doses of caffeine is limited, but one study indicates that they can improve alertness with fewer side effects than higher doses.
They can also try drinking a smaller quantity of stronger coffee. For example, one espresso is 2 fluid ounces (oz). It has less liquid volume but more caffeine (roughly 130 mg) than regular brewed black coffee, which provides around 95 mg of caffeine per 8 fluid oz.
Overdosing on caffeine is very rare, and it is usually a result of accidentally consuming too much in the form of supplements or energy drinks. People should be sure to read the labels of products with caffeine to make sure they are not overconsuming them.
Certain products contain potentially beneficial ingredients, such as theacrine, beta-alanine, and arginine silicate. These ingredients increase blood flow and claim to produce more noticeable post-workout muscle swelling.
For example, during a 2019 study involving 12 resistance-trained males, researchers compared TeaCrine (the branded version of theacrine) and 300 mg of caffeine. They found that the caffeine improved focus, energy, and motivation, while TeaCrine did not. However, it is important to note that these findings were self-reported by the participants.
People should always be careful when purchasing and consuming supplements, as these products are not regulated as tightly as pharmaceuticals. They should contact a doctor or pharmacist if they have any concerns.
