Final answer:
High-resistance strength training results in all of the following changes in trained muscles except decreased capillarization.
Step-by-step explanation:
Resistance training results in changes in trained muscles such as increased muscle size, increased strength, and increased development of connective tissue. However, one change that does not typically occur with resistance training is decreased capillarization. Capillarization refers to the formation of more extensive capillary networks around the muscle fibers, which is usually seen with endurance training but not with resistance training.
