As fitness awareness grows, more people are starting to focus on combining exercise with gut health. In addition to regular physical activity, experts are increasingly exploring how improving gut health can enhance workout performance and overall well-being. Award-winning registered dietitian and Yakult’s scientific manager, Dr. Emily Prpa, shares her insights on this topic.
The Connection Between Exercise and Gut Health
It’s no secret that exercise is beneficial for physical health, but in recent years, combining regular fitness routines with positive gut health habits has also been linked to improved overall wellness. So, how closely are these two factors related? Is there evidence to suggest that maintaining good gut health can enhance the effectiveness of your workouts?
According to Dr. Prpa, “Exercise plays a crucial role in promoting a healthy gut-brain axis by increasing the diversity of the gut microbiome. Physical activity also stimulates gut bacteria to release beneficial metabolites that can influence brain function and mood.”
“Moreover, the gut motility and blood flow changes induced by exercise help improve digestion and overall gut health, while also promoting oxygen- and nutrient-rich blood flow to the brain, enhancing the connection between the gut and the brain.”
To further explore this connection, Dr. Prpa shares insights on how focusing on gut health can enhance your training, as well as how certain types of exercise can help lead to a happier lifestyle.
1. Consistent Routine
Physical activities, especially those that focus on breath control, such as yoga and Pilates, are especially beneficial for the gut-brain axis. These exercises stimulate the vagus nerve, the direct communication channel between the gut and the brain.
By activating the vagus nerve, deep breathing and mindful movements help regulate the autonomic nervous system, promoting relaxation and reducing stress—two factors that are vital for gut health.
Practices like yoga, Tai Chi, and Pilates are particularly effective as they combine breath control with mindful movements. These exercises not only enhance physical flexibility but also promote emotional and mental well-being, further strengthening the gut-brain connection.
Additionally, outdoor activities during warmer months provide extra benefits for gut health through the gut-brain axis. Nature not only improves mental health—reducing stress, improving mood, and enhancing overall wellness—but it can directly impact your gut microbiome as well.
As summer approaches, adjusting gut health habits to maintain a balanced microbiome becomes crucial. Staying hydrated is key.
Higher temperatures increase the risk of dehydration, which can negatively affect gut motility and microbiome function. Dehydration slows down digestion, potentially causing constipation and gut microbiome imbalances.
2. Proper Fuel
If you prefer morning workouts, it’s important to fuel your body in a way that supports both your exercise and gut health. Here are a few strategies to consider:
Pre-Workout Nutrition: For a morning workout, opt for a light, easily digestible snack about 30-60 minutes before exercise. Choose something that combines carbohydrates with a small amount of protein, like a banana with nut butter or a slice of wholegrain toast with jam. This provides quick energy without overloading your digestive system.
Hydration: It’s essential to hydrate before your workout, especially after a night’s sleep when your body may be dehydrated. Depending on the length and intensity of your exercise, consider drinking a glass of water with a pinch of sea salt or adding some electrolytes to maintain hydration and electrolyte balance. Hydration helps support your gut during exercise.
Post-Workout Nutrition: After exercising, replenish your energy stores and aid recovery. Aim for a nutrient-rich meal within 30-60 minutes post-workout. Focus on a combination of protein (e.g., eggs, Greek yogurt, or plant-based proteins) and carbohydrates (such as sweet potatoes, quinoa, or fruit) to rebuild muscle and stabilize blood sugar.
For evening workouts, your nutrition and routine should focus on fueling your body for energy and recovery while avoiding heavy meals before bedtime. Here’s how to adjust your habits:
Pre-Workout Nutrition: About 1-2 hours before your evening workout, eat a balanced meal with fiber-rich carbohydrates, protein, and healthy fats. This meal provides sustained energy without feeling too heavy. Examples include a quinoa salad with chickpeas and vegetables or wholegrain pasta with a tomato-based sauce and lean protein.
Hydration: Stay hydrated throughout the day, but especially before and after your evening workout. Sip water throughout the day, and after intense exercise, replenish with water and electrolytes to balance minerals lost during the workout.
Post-Workout Nutrition: After an evening workout, replenish your energy stores and support muscle recovery. Opt for a meal or snack that combines protein and high-fiber carbohydrates, like grilled salmon or chicken with roasted vegetables and whole grains such as quinoa or brown rice. Avoid overly fatty or spicy foods, as they may disrupt your sleep or lead to indigestion.
3. The Right Investment
Exercise plays a crucial role in maintaining good gut health. Regular physical activity helps stimulate the growth of beneficial gut bacteria, promoting microbiome diversity and improving digestive function, which enhances overall health.
Exercise can improve gut motility, reduce the risk of constipation, and maintain the integrity of the gut lining. Research shows that exercise can reduce intestinal inflammation, lowering the risk of conditions like irritable bowel syndrome (IBS).
Moreover, physical activity promotes a healthy balance of hormones and neurotransmitters, contributing to both gut and mental health.
Hormonal imbalances are closely related to the gut-brain axis, and exercise plays a key role in supporting hormone regulation through this connection.
A balanced gut microbiome is essential for regulating hormones that affect mood, metabolism, and stress responses. Exercise helps balance hormones by positively impacting the gut-brain axis, reducing stress hormones like cortisol, boosting mood-regulating neurotransmitters like serotonin, improving insulin sensitivity, supporting thyroid function, and promoting a healthy, diverse gut microbiome.
Regular exercise—whether strength training, aerobic exercise, or mindful movement practices like yoga—can be a powerful tool for balancing hormones and supporting overall health.
