Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.

The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.
Periodization of training is based on the principle that different loads (e.g., light, moderate, or heavy) or power requirements recruit different types and numbers of motor units. Recruitment order is important from a practical standpoint for several reasons.

Bone tissue is “alive” and is a dynamic tissue that can respond to resistance training. In addition to the obvious effects of resistance training on muscle mass and strength, resistance training may lead to decreased risk for osteoporosis, fractures, and falls in later life.

The exerciser with 8 to 12 months of training experience can begin to include exercise complexes that combine trunk movement patterns with multijoint movements. Single-plane and multiplane movements can be performed using both open- and closed-chain exercises.

Considering that the term "power" typically evokes the perception of high-speed movement, many people are inclined to take the tenets of specificity to literally mean “train fast, be fast.” However, to create the most strategic methods of training and adaptation, it is vital to compartmentalize power into the primary testable and trainable elements.

Coaches can use drills to improve quickness and agility. The training session can improve the specific areas needed to increase performance results by setting up appropriate intensity levels, duration of drills, recovery periods, and volume of drills.

It is apparent that speed plays a vital role in successful baseball performance. Because of the short distances involved in the game, players rarely, if ever, achieve maximum speed and in actuality, it is acceleration that plays a much greater role in baseball.
