Are the bold claims made by pre-workout supplements real? |
In this fast-paced era, where almost everything is accessible at our fingertips, maintaining health has paradoxically become a luxury. This shift has led many, especially youngsters to focus on fitness. With gym sessions becoming a part of our daily routine, the demand to feel charged, and attain maximum effectiveness out of it has also increased. This rising urge has paved the way for pre-workout supplements, often marketed as performance boosters. Pre-workout supplements are a multibillion-dollar industry now and are expected to grow to $36.9 billion by 2033. But, the question is, do they really work? Are these bold claims met by these supplements? Here’s what the experts say.
What is in your pre-workout supplements?
Pre-workout supplements come in all shapes and forms. They are available as powders, pills, gummies, and drinks. And the big bold claims are quite tempting. They are specifically designed to boost energy, endurance, and focus before exercise.
The pre-workout supplements primarily contain caffeine, which plays a key role in enhancing alertness and reducing perceived exertion. This way, the people who take it put in more effort during workouts, making exercises feel less strenuous while potentially boosting performance. Some of the other key ingredients include beta-alanine – which reduces fatigue, creatine – which supports energy supply to muscles, and dietary nitrates like L-arginine which improves blood flow. Taurine is also added often for its supposed anti-inflammatory benefits. Though these ingredients are promising, the benefits are often minimal for casual gym-goers, which can be achieved through other simpler means.
David M. Kelly, a performance consultant and former head of sports science at Manchester United, told National Geographic that pre-workout supplements are not necessary for an average person. He stated that it is like comparing apples with oranges because a gym goer is not training intensely like a professional athlete. Professional athletes depend on supplements because they have a highly optimized training plan (with the advice of nutritionists, coaches, and psychologists) due to their demanding schedules and limited recovery time.
Simple strategies such as proper hydration, getting enough sleep, and having a pre-workout snack like a banana can provide similar effects to a pre-workout supplement.
The truth is, unless you’re training at an elite level with access to detailed performance data, pre-workout supplements likely provide minimal additional benefits compared to caffeine.
Studies suggest that it is rather the ‘placebo effect’ of such products is working rather than the product itself. Simply believing that you’re consuming something to enhance performance can boost focus, confidence, and gym results, even if the product contains no active ingredients.
Apart from the caffeine, music can also give you a similar effect. According to Brad DeWeese, director of human performance science at Penn State University and former NFL high-performance director, there is sufficient evidence to show that listening to music with higher beats per minute (BPM) during exercise can indeed result in higher outputs.
Risks of pre-workout supplements
Pre-workout supplements contain stimulants like caffeine, which can increase the heart rate. Overuse might increase your risk of heart disease, arrhythmias, or heart palpitations. As supplements are mostly in liquid form, it gets quickly absorbed, which can result in a rapid energy boost, and lead to a spike in certain compounds. The ingredients such as sodium bicarbonate, magnesium, and caffeine in the supplements can also upset the digestive system.
Amy Stephens, a sports dietitian for New York University and the Empire Elite Track Team, told NGC that if one decides to use pre-workout products, it’s important to choose reputable brands that undergo third-party testing and bear a United States Pharmacopeia (USP) or National Sanitation Foundation (NSF) seal.
