It not so much about how much weight is lost, as it is how the weight is lost and over how long of time shoud it take. As HWT who for some readonpacks on weight over the summer and during football season will shead a ton of weight and his body fat % will change at a faster rate than a lightweight who is naturally skinny, eats decently healthy, andesd active override same time period.
Thus for most wrestlers it may not be about the weight cutting numbers as much as how it's accomplished. If you are correctly eating during the preseason and season that in most cases regular weight cutting to make your ideal weigh class (as body fat would indicate) will not be an issue. Obviously it will take a person with more body fat longer to get to their optimal weight but that just means starting the process early and continuing it ar a more rigerous level If the end goal is important then the process is worth doing unfortunately too many people want to cut corners to make those end goals faster and bt using less long term control of their habits. That is the much larger issue under the old system and still one the current weight management program doesn't have an answer for. Tooany wrestlers are continuing to eating improper foods (sometimes in large quantities) and then restricting food and liquid from there body later on during the week to make up for it. Heck many times even replenishment items after weigh in are not helpful and sometimes hindering. They are still within their weekly weight lose limits yet this is far from the best way of maintaining or losing weight.
In many cases these wrestlers have plenty of extra body fat and are not near their minimum weight class, yet they are still crash dieting. Why is this? It's not because they have tried everything and just can't get the last few pounds off. It's because they feel like taking the easy road to the results they want thinking that will work. This is a similar problem to when wrestlers dont want to work on technique and then as soon as they feel outclasses rely on the one big "Whammy" move that worked well in middle school. The move wasn't done because it was perfect timing or because all other options were exhausted. It was done put of despitation because they thought it was there only chance to win since they didn't know enough technique to compete. Likewise, these crash diets are done out of desperation because the wrestler didn't want to take advantage of other options for making weight.
Health wise it is bad since you are consuming large amounts ofunhealthy foods, as well as, deprivation it of nutrition afterward to make up the difference. This large fluctuation in eating habits not only messes with your body during a time of development, not to mention athletic activity. This leads to more physical and mental stress, muscle growth issues, sleep problems, irritability, and/or other short and long term health issues.
It also is bad for your sports preformance. By not building up of essential suppliments early in the week and then drain many that were already stored up in your system later in the week you are essentially running on a reserve tank. While this may carry you through to a win in one good match the effects wi show in your performance and your post match actions. It will also carry on with you through most of the day. Meaning even if you try to replenish your body afterward any additional matches you have will show residual effects from the actions you took during the earlier part of the week.
Psychologically wrestlers do this because they think the drain won't effect them. The idea they did it before and still won is enough to try it again. Or they don't have the self control to eat certain food while avoiding others. Yet, the result of this is a crash diet which everyone hates later in the week. This should be resolved by providing a better nutrition education to wrestlers and getting a parent and peer support system for these efforts Or they feel the weight cut is essential tigons them a size advantage. Yet you are the same weight as your opponent and your muscle depletion from losing weight makes up for the strength advantage you would have had. Sometimes the only reason these theories even work out for wrestlers is because there opponent was dumb enough to follow similar habits causing them to also have a disadvantage. Thus falsely giving the winner the feeling that this method was worth doing.
Thus, in most cases during the preseason and season a regular structured diet, the skipping of major gorging episodes, and a regular exercise routine will be enough to get an athlete to his optimal performance weight while still retaining the stamina and strength needed to preform well throughout a day of wrestling. Anything else is just playing roulette with your health, preformance on the mat, and your win/lose record.
