American Journal of Medicine Suggests Crossfit Does More Harm Than Good: But Is It True?
Crossfit and other forms of HIIT (high intensity interval training) are the current big things in the fitness world, and with good reason. HIIT allows you to burn a lot of calories in a little amount of time. This is achieved by getting your body to a high level of exertion and then doing bursts of intense exercise such as sprinting in twenty to forty second intervals. One of the best results of this is that your metabolism receives a nearly 24 hour long boost.
It cannot be denied that you can achieve some impressive results with crossfit and other forms of HIIT. There is a good reason why schools promoting these methods have sprouted all across the country. However, in a new article from Telegraph we may see how chasing the trend could actually be sabotaging the fitness regiments of millions.
A new study from the American Journal of Medicine found that many newcomers to HIIT exercise are developing symptoms similar to rhabdomylosis, a condition that is commonly associated with military training. This is a condition in which the muscles essentially begin to break down. As they break down muscle constituents begin to leak into the blood stream. Over time this can lead to serious kidney damage. This makes sense given how many people will brag about how badly their Crossfit session “wrecked” them.
So does this mean that Crossfit and other forms of HIIT are bad? No, of course not. What it does mean, however, is that if you are just starting to get into fitness and exercise then you do not need to attempt HIIT. Crossfit and HIIT are intended for people who have worked to the level of being able to handle that level of exercise. Build up to it. Condition your body and when you are more comfortable with exercising on a regular basis you should be ready to start.
It also needs to be said that a major reason for this painful phenomenon is that some people are becoming addicted to their workouts, or at least act like they are. There are people who will do crossfit and HIIT sessions everyday with little to no rest. They think because they are not exercising for extended sessions that doing HIIT everyday is benefiting them. The truth is that they are burning out their bodies. Days dedicated entirely to rest are absolutely essential to those who want to get fit because they ensure that the body has time to recover from the exercise.
There are 3 basic factors that you need in order to get and stay fit. Diet, rest, and exercise. You cannot cut out one of these factors and expect to have any level of success for any real length of time.
Crossfit or HIIT should be no more than 2 to 3 days a week, and the harder you push in a workout, the more recovery time your body needs to repair the damage and allow lactic acid to subside within the muscles.
When you push your body hard, you have to feed it correctly or it will ultimately damage your body. This is where supplements and protein powders come into play, and should be taken seriously by both women and men. They help repair your body and get you ready for the next round of exercise.
Crossfit and HIIT are fantastic tools. They help people lose weight, stay fit, and improve their conditioning. However, you cannot overdo a fitness regiment and get positive results. All you will do is burn yourself out, lose motivation, and possibly injure yourself. Make sure that you are ready to take on a more intense fitness regiment by talking to your doctor about what you need to do. And if you are already doing HIIT then make sure you are taking the necessary recovery days, otherwise all of your efforts could be for nothing.
