The gut microbiota is one of the crucial factors that affect human health and, by extension, athletic performance. It is an essential part of a complex network of interactions between the gastrointestinal system, immune system and brain. If any external or internal factor alters this equilibrium, it will inevitably have repercussions on your overall health.
There are several ways a healthy gut can influence your performance and help you stay at your peak longer.
To enhance your athletic performance, you need nutrients in a trusted diet plan — macro and micronutrients that support all physiological functions to perform better and recover faster.
Good bacteria populating the intestine are essential for synthesizing vitamins like K, B₁, B9 and B12, minerals, and other essential nutrients. If these bacteria are in excess, or there is a presence of harmful bacteria, the digestive process slows down — consequently, the body’s ability to absorb nutrients decreases. You will get absolutely no benefits from eating healthy if your body does not absorb the nutrients you consume. The eventual deficit in essential nutrients will negatively impact your performance and recovery.
Bone health is an essential factor for athletic performance. Short-term risks like injuries or long-term risks like osteoporosis are not worth chancing. A healthy gut promotes nutrient absorption. Intestinal calcium and magnesium absorption are essential for maintaining optimal levels of these minerals and strengthening bone health.
Gut microbes, or the so-called good bacteria, help us maintain a proper-working antioxidant defense system that effectively neutralizes the excess of free radicals.
Physical activity has a beneficial effect on gut health as it can enhance the number of good bacteria. Still, harsh and long-lasting physical activity can alter the intestinal microbiota and damage the intestinal barrier. As an athlete, you should focus not only on your training programs but also on your gut health. Achieving a balanced gut microbiota should be a fixed part of every nutrition and training program. Many athletes, especially long-distance runners, experience gastrointestinal disorders during or shortly after training or competition. Maintaining your gut health can reduce and, in some cases, prevent the symptoms of gastrointestinal distress.
Every athlete knows that a good night’s sleep is the holy grail for performance and recovery enhancement. Around 80% of serotonin, which is the precursor of melatonin, is produced by gut bacteria. Low levels of this neurotransmitter can cause sleep disturbances and therefore affect your athletic performance negatively.
A healthy gut will allow adequate water reabsorption and solute transport, resulting in better hydration.
Numerous factors can cause a reduction in the effectiveness of your immune system, especially before competitions. This could expose you to a greater risk of catching upper respiratory tract infections. The gut microbiome is closely related to the immune system. It is a bi-directional relationship that favors both parties. The gut microbiome is crucial for the development of the immune system from birth.
According to research, if you don’t consume enough fiber, your gut microbiota can cause inflammation because the bacteria in the absence of fiber attack the intestinal mucus. Mucus also acts as a protective barrier against microbes, and when they come into direct contact with the intestinal cells, they cause inflammation. Exercise-induced oxidative stress, leukocyte infiltration, and the production of pro-inflammatory cytokines cause a wide array of inflammation symptoms. High-fiber foods stimulate bacteria to produce chemical compounds beneficial to the body, such as butyrate, which, according to researchers, can protect us effectively against inflammation.
There are many ways you can improve your overall gut health. Focused training and preparation of your gastrointestinal organs will improve the absorption of nutrients during practice, training, and racing. Having a well-prepared gut will prevent bloating, flatulence or malaise. Through slow adjustments of the amounts of nutrients, the gastrointestinal system will get used to handling the quantities needed.
What to pay attention to:
A healthy gut can influence your performance and help you stay at your peak longer. Paying attention to what and when you eat will pay off in increased athletic performance.
