Coffee…everybody’s favorite drink…Caffeine affects almost every system in our body, but its impact on mood, alertness, metabolism, and exercise performance are produced by some pretty specific physiological interactions.
How does caffeine in coffee works its magic on your workout?
Mobilizes Fat From Fat Tissues
The epinephrine travels through the blood to the fat tissues and sends signals to break down the fats and release them as free fatty acids into the blood, where they can then be used as fuel. More fuel equals stronger and longer workout. This reaction especially enhances endurance exercise.
Delay Of Muscle Pain
The effect of caffeine on strength training is less well-documented, although recent studies have shown that ingesting caffeine prior to weight training increases the amount of weight lifted,as well as number of reps.
This is possible, due to caffeine’s ability to blunt pain responses so that your muscles don’t get fatigued as quickly during resistance training
Boost Energy And Mood
By blocking neurotransmitter adenosine,caffeine boosts the firing of neurons and the release of neurotransmitters, including dopamine and norepinephrine. This affects vary brain functions: memory, mood, vigilance, energy levels, reaction times, and even general cognitive function.
More Calories Burn
This one doesn’t directly affect your workout, but it goes hand in hand with the results of your workout. Ingesting caffeine before a workout can actually increase the number of calories you burn from the workout.
A study published in the International Journal of Sport Nutrition and Exercise Metabolism found that trained athletes who took in caffeine pre-exercise,burned about 15 % more calories for three hours post-exercise, compared to those who took a placebo. Caffeine also blunts your appetite, which could also aid in weight loss.
Caffeine can also affect how well your body burns calories when you’re not even exercising. Studies show that caffeine can increase our resting metabolic rate (how many calories we burn when we’re doing nothing) by 3 to 11% Larger doses have an even bigger effect.
So What Does This All Mean?
Should you drink 10 shots of coffee before each workout? The answer is no.
Yes, caffeine may help you push just a little bit harder during your workouts, resulting in improvements in muscle strength and endurance.
But there are also side effects of drinking too much caffeine, including:
- inability to focus
- gastrointestinal unrest
- increase of risk of heart arrhythmia and mild hallucinations
Obviously, any of these could have a negative impact on your race or workout.
Therefore,be moderate in everything you do!
