It can be very difficult working with athletes. What makes things even more difficult is working with athletes who have different coaches (HS Athletes). No matter how in sync you may think you and the coach are, your ideals are going to be different.
Differing ideas make sense. When personally training an athlete, or rehabbing an athlete, you have one goal, make that individual better than they were before you hooked up. Working with an individual gives you the chance to do so, however a coach doesn't have that ability. A coach must work with the team, and in doing so, must work with a variety of skill levels and abilities.
When it comes to designing a training regimen, a coach is going to generalize their attack. More often then not, they are going to create a work out for the AVERAGE athlete on their specific team. The better the coach, the more sport specific the work outs of course.
There are a few different types of coaches that you will deal with as either an Athlete, Strength Coach, Athletic Trainer, or even parent.
Seasonal Coach - The seasonal coach goes out their from day 1 of pre-season to the last game of the play-offs (hopefully not though, because he/she can't get paid extra). This type of coach is in it for the money, granted he/she usually has an interest and take enjoyment in the sport. He/she doesn't care if his/her athlete gets outside help, it means he/she can do less as a coach. Generally, not a great coach.
Overbearing Coach - This coach, on paper, is a great coach. He/she is 100% committed to his/her teams, to a fault. He/she will eat, live, and breathe the sport. Only problem with this coach is that everything must be done his/her way. If your ideas differ from his/her philosophies you are considered a cancer. If anything you do or say that is different, he/she will tell everyone that you do not know what you are talking about. Apparently being a professional in a specified area isn't enough for this coach.
Hungry Coach - This coach wants to get results. He/she is extremely eager to learn about every aspect of his/her specific sport. He/she is open to anything and anyone, as he/she hasn't really established himself/herself in the sport. As one professional to another, this is by far the best coach to work with, as this coach respects the ideas of outside help, especially when he/she truly does not know what he/she is talking about.
Burnt Out Coach - This coach has been doing things one way for years. Sure, he/she had results back in the 70s, but times sure have changed. He/she doesn't adapt to anything, and try to get everything to adapt to his/her ways. This coach has the love and desire, but is very stubborn. He/she has been around and if they had any success, it was in the beginning of their tenure.
There are plenty of other coaches, many that are combinations of the above. Coaches are a fickle bunch, no way around it. However, if you find yourself involved with any of the coaches, remember, keep doing things your way, as long as you continue to see results.
