THE HUMAN BODY DOES NOT LIKE FATIGUE. The body in general wants food, sleep, and recovery. However, as human culture has evolved over time, movement and activity has grown in popularity, and looking good has become a cultural norm. Similarly, so has the need to move our bodies to play a sport or go to the gym. That’s the moment when they meet an awful feeling called fatigue.
Physical fatigue can be defined as the effect of a certain stress, that affects the body’s capacity to protract an effort. Its effects manifest in different ways. The more intense and extended the effort, the harder it becomes to accomplish the task, both physically and mentally.
From a mental standpoint, one of the effects of fatigue is to make you stop believing in yourself. Your brain can find endless reasons to stop. It’s your innate survival instinct that tells you things like “why are you doing that?” or “You are tired, you have to stop” and “You can’t”. An expert athlete knows how to shut off their brain and keep on going to reach the end result, regardless of fatigue. Often, it is this ability to overcome fatigue that makes a good athlete a champion.
From a physical standpoint, instead, the effects of fatigue are several. They lead your body to a progressively decreased ability to sustain an effort as long as it is protracted. A particular feeling of heaviness can be perceived. The same actions require an augmented voluntary mental focus, but despite all your efforts, your movements will be harder and slower. This explains why the barbell is lifted very slow when you’re attempting a maximal lift (1RM)! The reasons for the phenomenon of velocity loss have to be investigated in the workings of the various chemical reactions that occur in your muscles, while you’re struggling under the barbell during a bench press or a squat.
The question is: why is the loss of velocity significant in training? Because it has been shown that the rate of velocity loss is fixed and directly correlated to the amount of effort required in a certain activity. So, when you know the relationship between effort and velocity loss, and you can measure the velocity of the lifts, thanks to a device like the Beast Sensor, you’ll automatically be able to fix the exact amount of effort required for every training session in advance, accordingly with your periodization, and control the level of fatigue.
I know, the laziest amongst you are already celebrating, thinking that this means less fatigue. But I have bad news for you: fatigue can’t be avoided! However, the good news is that through the measurement of speed, you can control fatigue and your workouts will be elevated to another, greater and smarter level!
