What Happens In The Body During A Weighted Workout?
If you’ve been training for a while, you know that physical activity leads to visual and functional changes in the body.
Weight training has been proven to lead to changes in the body, including muscle growth and development. And it all starts with a few minor exercises that stimulate your central nervous system (the brain). You know those sore muscles after working out for an extended period of time? That’s because we are activating our muscles during intense workouts by contracting them against weights or other resistance such as gravity itself!
Muscle fibers
Our bodies are made up a variety of muscle groups and each one has different fiber types.
We have slow twitch muscles for activities that don't require much force, like walking or climbing stairs; these take longer but can work steadily hours on end without getting tired because they're not strong enough to overpower the weight being pushed against them (that is why we call these type "endurance fibers").
On the opposite side there's fast twitch motor units which function better when you need more power in your movements--like sprinting across gymnasiums! Fast-twitch muscle fibers produce the greatest amount of force, but they fatigue quickly when under high exertion.
"During a weighted workout and more specifically during challenging working sets you activate your fast twitch muscles in order to endure heavy loads." "The heavier the load there are on these types or proteins their recruitment is greater as well because it takes an intense degree for them all work together at around 75% max strength capabilities.""
The heavier the load, the more fast-twitch fibers are recruited.
At around 75% of your maximum strength capabilities, all these muscle groups have been activated with a frequency that is predictable but not intense enough for significant bulk gains yet; increasing up to 80%. While there's no magic percentage when it comes down to just how much force you can produce without getting hurt (85%-100%), 85 - 100% represent an optimal range in which we would expect our performance and results from exercises/training sessions increase most drastically.
ATP, Creatine and glycogen
It takes energy to contract and relax muscles. The main sources of this fuel are adenosine triphosphate, also known as “ATP”; however it doesn't last for long in intense workouts that require more than 5 seconds worth of activity due mostly because there isn’t enough time before another source needs regenerating again like creatine does 10 additional seconds after high intensity exercises end.
Creatine grants temporary assistance during these times when ATP becomes depleted but once its spent then you will have lost some strength too unless something else is done/added which can create new muscle fibers or boost your current ones through supplementation.
When your stores of ATP and creatine are gone, the body starts relying on muscle glycogen to sustain activity. Muscle Glycogen is essentially glucose stored within muscles as a result from carbohydrate digestion; it can be broken down into blood sugar through exercise or metabolism by cells if necessary.
Muscle Protein Breakdown
Muscle protein breakdown is an essential process that occurs when your muscles contract repeatedly under a heavy load. This micro-damage to the muscle leads to growth and repair of damaged tissue, as well as enhanced performance during intense workouts due in part from increased output by our nervous system which uses up energy resources more efficiently than before while also stimulating new metabolic pathways involved with building stronger cells .
One of the most important parts about building muscle is giving your body enough carbohydrate energy to get through those heavy workouts. When we use up our muscles’ stored glycogen, it triggers a flurry recovery processes that help us recover and refuel while also repairing any damage on its way there too! So make sure you eat lot of carbs after every workout - this will keep them growing strong and consuming enough protein so that your body can maintain its recovery processes.
We all want to be in peak physical shape and we know that the more muscle mass you have, the better your overall performance. Muscle protein breakdown is a necessary process for growth and repair of tissue as well as improved athletic performance due to increased output by our nervous system which uses up energy resources more efficiently than before while also stimulating new metabolic pathways involved with building stronger cells. It’s important not only to work out hard but eat right too--including enough carbohydrate energy!
