What Does "Pre-Workout" Mean?


Pre-workouts are dietary supplements that might help you do better during your workout and recover faster afterward. Even though pre-workouts are generally safe, they do come with some risks, such as interactions with medications, and the research on how well they work is mixed.

If you're thinking about using these products, it's best to talk to a doctor or nurse first.

You may have heard of taking a pre-workout supplement, whether you've been working out for a while or are just starting out.

You can take nutritional supplements called "pre-workouts" before you work out. It has been suggested that taking these supplements will help you do better during your workouts. 

If you've never used a pre-workout supplement before, you may be interested in how they work and what they contain. Here are the important facts about pre-workout.

What is the point of pre-workout?

These kinds of supplements claim to do a few things, including:

  • Improving your energy levels
  • Improving how well you do during exercise
  • helping with recovery after a workout
  • Getting your body ready to work out
  • Lessening the chance of getting tired or hurt while training

What Does Pre-workout Have?

Pre-workouts can come in different forms, like pills, powders, or bars. They also have different ingredients. Dietary supplements for exercise or athletic performance can contain anything from vitamins and minerals to plant-based ingredients and proteins (e.g., ginseng or beet juice). 

There are 21 different kinds of ingredients that can be used in supplements for exercise and athletic performance. Some of them happen naturally in your body or in foods made from plants or animals. But not all of them work to improve how well you do in your workouts. 

Some of the things that might go into a pre-workout supplement are:

  • Caffeine: Caffeine is a stimulant that may help thinking and performance during exercise by making you less tired.
  • Branched-chain amino acids (BCAAs) are thought to increase muscle endurance and lessen the damage that exercise does to muscles.
  • Nitrates, which are nitric oxide agents, make more blood flow to the muscles that are being used.
  • Creatine: Improves performance and helps with challenging adaptations in training
  • Beta-alanine: Enhances exercise at a high-intensity level by reducing the build-up of lactic acid that can cause fatigue in athletes

It's important to know what your pre-workout of choice is made of. You'll want to check the label to ensure that all ingredients are listed with the amounts of each ingredient clearly indicated.

Also, only "dietary ingredients" should be in dietary supplements (e.g., vitamins, and herbs). No pharmaceutical ingredients (e.g., prescription medications) are permitted in supplements. Companies that make supplements are also not allowed to say that the supplements can help diagnose, treat, cure, or prevent diseases. 

How long until it starts to work?

You can take any pre-workout supplements right before you start your workout. One study found that participants who took pre-workout supplements did so between 15 to 60 minutes prior to exercise. However, most took the supplements between 15 to 30 minutes, which is the time interval matched with what most supplement manufacturers have recommended on their product labels. 

More research is needed to determine exactly when pre-workout kicks in and how long you might feel their potential benefits. However, the length of time it takes for pre-workout to work and how long the effects last may, in part, depend on the type of supplement you have taken.

For example, if you take creatine as a supplement on its own, it can be beneficial in the short term (i.e., for minutes) when you do an exercise such as a sprint. At the same time, creatine has not been shown to be helpful for longer periods of time. 

Does pre-workout effective?

Different pre-workout supplements work in different ways. Each ingredient in a supplement may have its own level of effectiveness, but when different ingredients are mixed together, these levels may change. 

For example, the use of caffeine has been mixed in studies when it comes to efficacy. One study found that people who took a supplement with caffeine had more power on average than those who took a placebo or treatment that was similar to what they were already doing. 

But other research found that using a pre-workout supplement or taking a similar amount of caffeine did not improve performance during resistance exercise.

Some people also think that different supplements may work better or worse for different types of workouts. Research has shown that multi-ingredient pre-workout supplements (MIPS) are great for muscle endurance but not for strength. MIPS also gave mixed results for strength exercises and maybe even good results for endurance exercises.
