Supplementing For Sport

Author: Rudy Mawer Contributing Author

Although supplements are extremely popular in the bodybuilding world, few recreational athletes are yet to take advantage and use them to their full potential.

While there is mounting evidence and research supporting their use in the fitness industry and bodybuilding, most supplement research begins with athletes in sport-based settings.

For any advanced athletes reading this, remember, a 5% improvement from supplements could be the difference between first or last place. In high end sport, the margin between the winner and loser is normally within only a 1 or 2 % range. Therefore, the power of these research-proven supplements should not be under-appreciated.

Here’s a list of the best supplements for a variety of short and long duration sports.

Beta Alanine

Beta Alanine is possibly one of the world’s leading supplements for any athlete, especially for those performing exercises or activities between 1 and 10 minutes.

It works by boosting your muscles’ carnosine levels, which can help reduce fatigue and enhance performance. When exercising, you are likely to be familiar with the “burning” sensation we receive from our muscles. This is caused by an increase in metabolites or waste products, such as hydrogen ions.

After some time, this accumulation causes the muscle to become acidic, which reduces its ability to contract or produce force. As you well know in the gym or during a competition, when that burn occurs your performance takes a rapid drop. Luckily, the boost in carnosine can fight off this process and reduce the buildup, helping you push one step further before fatigue kicks in.

As mentioned, beta alanine has uses in most sports except for steady state endurance exercise. Even in mixed team sports that may last for 1 hour or more, it can help with each individual bout. For example, sprints in football, soccer, rugby etc., or, 1 - 3 minute rounds in boxing or combat sport.

In one study they tested high intense sprints for cycling, which can have relevance for any sprint type activity and not just biking. They found that it improved time to exhaustion by 16% over the placebo (non-supplement group) (Hill et al., 2007).

For a specific sport, they tested beta alanine in college football players and found it helped reduce fatigue and improved several aspects of fitness testing, including bench press performance (Hoffman et al., 2008).


Along with Beta Alanine, Creatine is one of the most powerful supplements for athletes. Although its ability for boosting muscle growth is well known, it can clearly enhance high intensity and short duration exercise.

As it works to provide extra ATP energy, its main use remains in very sharp short bursts such as 1 - 15 second sprints. However, its use is supported by other research showing it can boost performance up to 60 seconds or several minutes.

Firstly, one meta-analysis, (a type of research which reviews all the current studies and trials), summarized it can provide a 1 - 15% performance benefit. As mentioned at the start, a small 1 - 15% improvement may not seem like much but, for a well-trained athlete, 15% improvements could take years or even decades to attain (Kreider et al., 2003).

Another study tested it in highly-trained soccer players, who perform multiple short sprints within a game, much like other sports such as football, tennis, basketball etc. In this study, they found each sprint was consistently faster for the athletes using creatine.

Finally, other research has shown improvements in explosive power and jump ability which, again, has application into most sports imaginable (Mujika et al., 2000).

Other Beneficial Supplements

While I’ve covered the main 2 supplements, there are still some key players that can help any athlete take their game a step further.

Here’s a brief overview of each:

  • Citrulline: Citrulline is a very promising supplement used to enhance exercise performance and cardiovascular (heart) health. It has been proven to reduce fatigue and prolong performance for both short and long duration sports.

  • Betaine: Betaine is derived from the vegetable Beetroot. It is provided in supplement form as it’s concentrated into a consumable amount (you would need 6-7 Beets per day to reach the required dose). It can improve both short and long duration sports and activities by working as a NO (Nitric Oxide) booster and blood flow. The research is only just emerging on Betaine; however, initial research has shown it can enhance power and performance.

  • BCAA: Although best known as a fitness or bodybuilding supplement, BCAA can also benefit athletes. It has multiple benefits, along with the most obvious one of protecting an athlete from muscle loss. It can help reduce muscle damage and aid in recovery allowing them to train more often and with more intensity. Additionally, other research has shown how BCAA can help reduce central fatigue in the brain, by blocking certain receptors that can become active during exercise.

  • Recovery Shake (RE-KAGED): Similarly to above, a complete recovery shake, or whey protein shake such as RE-KAGED, can be a valuable tool for an athlete to help them recover after the workout. Over the long term, this can play an important role in supporting an athlete’s training, especially during a competition season when games and training are back-to-back or even twice per day. It’s well known that most athletes under-consume on protein, making a whey shake a very important addition to help them increase their daily intake.

  • Caffeine: Last but not least, caffeine is one of the most beneficial supplements for enhancing sports performance. It has multiple benefits, affecting both the muscles that are being used along with the brain and central nervous system. Combined, this can reduce both central (brain) and peripheral (muscle) fatigue while, as you well know, enhancing focus and energy. It can also enhance fat oxidation or fat burning, which can help an athlete drop fat whilst also prolonging performance because it provides an alternative fuel source.

  • Add in PRE-KAGED

    As you can see, there’s a ton of options and brilliant supplements for the athlete. While it may be hard to pick just one (as they are all so great), you can just opt for a complete blend such as PRE-KAGED.

    When working with elite level athletes, I will personally recommend PRE-KAGED for a very easy and done-for-you work out solution, which includes every single ingredient discussed above. Best of all, PRE-KAGED is third-party tested, safe and completely legal, backed by Informed Choice approval and more.
