I haven't read the other answers so I hope I'm not being too repetitive.
Your girl doesn't have anything against you. She's just becoming more aware of herself as a person. She's interested in asserting herself.
This is a good thing! You did it when you were that age, too. But she can't use words yet to assert herself, so she does it bodily.
Wrap your mind around the idea of being both FRIENDLY and FIRM. Even though it might seem she isn't paying attention, talk to her as you buckle her into her car seat or change her diaper. Don't try to distract her if she's not distractible, but talk to her about what you're doing as you do it. It can't hurt, and it might help. Think of her struggles as her playing a little power game that she needs NOT to win. Babies can be real drama queens (and kings).
Having her do the things you need her to do may take some "physical wrestling," as you put it, but that's not the same thing as abusiveness. She may not like doing what you want done, but you're the mother, and it's your job to go ahead and do what you know is best.
Your daughter may be strong physically, but she's not as strong as you are! You can admire her strength, but you can still be firm and friendly. (I'm emphasizing those two words because it took me some time to get the notion that the two can go together!)
This is a reason God gave children parents. The baby is starting to grow up and have opinions about things - but opinions aren't the same as knowledge and wisdom. She wouldn't have the slightest chance to know what to do without a parent to teach and train her.
You can't reason with a one-year-old. You just need to lead. Don't think she should be appreciative of what you're doing for her, either. That won't happen until she's thirty! And yes, if she had the opportunity and the motivation, she would make the same power struggle with other people. It's part of her growing up.
Do you know some mothers where you live who have children a little older than yours, and whom you might consider role models for you in this baby-management period? Talk to them. Pick their brains. They'll help you learn how to do it and, hopefully, will encourage you. None of us was born knowing what to do. Maternal instinct doesn't go that far. Learning is good.
