Two commonly used stimulants before training are caffeine and beta-alanine. Caffeine acts as a central nervous system stimulant, providing increased alertness, focus, and energy levels. It works by blocking adenosine receptors in the brain, which reduces the feeling of fatigue and promotes wakefulness. Caffeine can enhance physical performance, improve endurance, and increase the rate of calorie "burning". It also helps with mental performance, reaction time, and concentration.
Beta-alanine is an amino acid that enhances exercise performance by increasing muscle endurance. It combines with histidine in the body to form carnosine, which acts as a buffer against acid build-up in muscles during high-intensity exercise. By reducing the accumulation of lactic acid, beta-alanine delays muscle fatigue and allows for prolonged training sessions. It is particularly effective for activities that involve repeated bouts of intense exercise, such as weightlifting or high-intensity interval training.
Both caffeine and beta-alanine have been extensively studied and are considered safe when used in moderation. However, individual responses may vary, and it's important to be mindful of personal tolerance levels and any potential side effects. It is recommended to consult with a healthcare professional before incorporating these stimulants into a training routine.
