“Do you have a source of the information or somewhere to read further?”
Walk into any University bookstore that emphasizes athletics and pick up books dealing with exercise physiology, motor skill acquisition, anatomy, kinesiology, diet and energy plus many more and you will see that the direction of baseball training timelines for youth in particular has been evolved by monetary considerations, scouting opportunities and well meaning but incorrectly understanding of physiology coaches and establishment. Your son can’t be the best he can become with this current training understanding. If he is performing “general” training elements and not “sport specific”
he is susceptible to mediocrity in performance to the exercise physiology tenet the 20% principle.
Twenty Percent Principle Researchers found that increased muscle fiber cross-sectional diameter accounted for only twenty percent of those muscles increased weight lifting abilities. Consequently, the remaining eighty percent of the increased training abilities result from central nervous system adaptations. Training stimulates hormonal secretions that increase muscle growth, increase muscle contractility and decrease Golgi Tendon Organ dampening of trained reflexes. Training decreases cerebellum’s dampening effect on ballistic movements. Training increases myolinated motor nerve conduction velocities. These central nervous system adaptations and engram formations explain eighty percent of training benefits. Therefore, eighty percent of training must emphasize central nervous systems. The Twenty Percent Principle completes the circle back to the Training Specificity Principle. Training programs must specifically enhance specific motor skills at specific competitive intensities.
Training regression Whenever athletes of any age practice skills at increasing intensities, the involved bones, ligaments, tendons and muscles have to make physiological adjustments. During this physiological adjustment period, also called the regression period, the bones, ligament, tendons and muscles are not able to perform at their previous levels, such that athletes complain that they cannot perform the activity at earlier intensities.
However, when athletes continue to train through these regression period, the physiological adjustments will enable them to perform at greater and greater intensities.
When baseball pitchers say that they have 'tired or dead arm,' they mean that when they try to throw as hard as they can, the baseball does not go as fast as they thought it would.
'Tired or dead arm' is the normal response of baseball pitchers trying to achieve higher levels of fitness. When training overload stimulates a physiological response, the body mobilizes its resources to meet this training overload. That is, the body builds new bone, ligament, tendon and muscle tissue.
To Exercise Physiologists, this means that the body has entered regression. During regression, no matter how intensely they try; they are not able to get the results that they want. For deep training regressions, it takes about five weeks from the last time they increased the stress that they placed on their body to meet a training overload for these tissues to mature and respond. To varying degrees, all baseball pitchers, even those who maintained over the off-season will have 'tired or dead arms.' The length of time to come out of 'tired or dead arms' depends on the depth of the training regression.
When athletes apply stress greater than muscles are able to withstand, these muscles enter a state of regression during which they mobilize the recourses that they need to make the physiological adjustment required to meet this training overload. During regression, athletes should not add the stress of competition.
When baseball pitchers throw with greater intensity than usual, they stimulate a physiological response in the involved tissues. In Exercise Physiology, we call this process, 'Regression.' Regression is when the body is mobilizing its resources to meet the training overload. During regression, muscle fibers cannot contract as quickly. However, when athletes train through the regression, the involved muscle fibers will contract even more quickly.
During regression, no matter how intensely they try; they are not able to get the results that they want. For deep training regressions, it takes about five weeks from the last time they increased the stress that they placed on their body to meet a training overload for these tissues to mature and respond. Athletes cannot train and compete at the same time. and, they need three weeks to start to come out of the hard training regression. With lesser time and effort training the regression period shortens
The only way to come out of training regression is to train through it. Eventually, you will gain the fitness that will enable you to compete at the level of your new intensity.

“My son is 14 and has been working out for about 6 weeks and has made similar comments.”
Is your son biologically 14 also? Or is he chronologically 14 and biologically more or less than this, because it makes a huge difference at this age both ways when dealing with increases in duration and intensities!!
