Look at the records being broken this year in baseball. If I lift weights, I will become more uncoordinated. In the long run, weight training should improve coordination. There is some neuromuscular adjustment to an increase in strength, which can affect athletes. However, athletes do their hard weight training in the off season and do a maintenance program during competition, which allows for peak performance and timing.
Weight training produces faster results and helps prepare the body to participate in sports.
Many personal trainers specialize in helping both professional and recreational athletes condition themselves for both fitness and the sports they play. Research shows that gains in strength and muscle mass can occur at any age. Find a qualified personal trainer or instructor who can teach you the best tachniques of weight training and get you started on a simple program. The believers in weight training, who do it regularly, should evaluate the quality of their program design, making sure it is balanced and safe. Constantly seek to improve you form and technique, not just increasing the amount of weight you lift.
