Why caffeine is not a consistent performance aid for all recreational athletes?
I recently did an ancestry gene test and discovered that I'm in the 50% of the population who are slow caffeine metabolisers (CYP1A2 AC and CC genotype). I was a little curious to find out what this means and what positive or negative effects caffeine can have on our health and performance?
Numerous studies have linked caffeine with positive health effects like reduced risk of obesity, diabetes, and heart disease. However, recent research suggests that the effects of coffee on health aren’t the same for everyone, and may depend on genetics and other factors.
I love coffee—and I know I’m not alone.
Recreational athletes body types and energy system demands
When working with recreational athletes, it's important to understand their body type and the energy demands of their training and competitions. In a future post, I want to write about the protein demands for different sports. Still, it's critical to understand how to exercise's frequency, volume, and intensity impact the macronutrient (protein, carbohydrate and fat) intake requirements.
No one diet is right for everyone. The right diet should be based on many individual factors. The food we eat contains information that speaks to our genes, not just calories for energy. Science tells us that obesity is ultimately the result of a hormonal imbalance, not a caloric one. It's not about "eating less". It's about eating more of the right foods that nourish and fuel the body and mind. It's not about "moving more," it's about how movement supports your health and encourages positive adaptation, not fatigue.
Fuelling for the demands of training
A low dietary energy intake relative to exercise energy demands (ie low energy availability) may result in an array of medical issues. Many recreational athletes following mainstream diets are under-eating. Most are not eating enough to fuel their training, to improve their body composition (decrease body fat and maintain/increase lean muscle). 99.9% of recreational athletes are not getting enough micronutrients, like vitamins and minerals, in their diet to balance their hormones, strengthen their immune system, achieve their fitness goals, and increase their healthspan.
