This article discusses the influence of lower-body power on soccer performance in collegiate female soccer players. It also covers testing for muscular power qualities, different training modalities to use, and sample training programs as examples.

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.

Developing safe and effective exercise training programs requires the application of abundant training variables and the implementation of appropriate progression for each variable. Importantly, the outcomes of each training program are the product of these variables and their progression, so practitioners are keen to select methodologies and overload strategies that effectively support their target training outcomes. One such training variable is mechanical loading, which describes the forces of gravity, resistance, and muscle contraction and how these forces affect musculoskeletal adaptations. Numerous research articles and texts have been published regarding mechanical loading and its effects on exercise adaptations; however, these findings can be arduous to organize, which requires additional time investment by professionals. Developing a succinct system is critical because practitioners face clients and patients with a wide range of physical skills and challenges, and having an easily referenced loading guide may assist them in designing appropriate strength and conditioning or rehabilitation programs. Thus, the purpose of this review is to define and describe the mechanical loading continuum and its individual components to better assist the practitioner in identifying appropriate exercise modes and progression strategies.

Beyond the programming, exercise technique, and human physiology, it is also important to create a customized system for sales success. Re-framing the purpose of the sales presentation in the proper light and creating a customized system that will allow a fitness professional to sell their services with integrity can allow them to help more clients.
