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.

This course is an introduction to force plates and performance testing. This course covers the basics of setup and calibration of force plates, and then walks through several fundamental performance tests including squat jumps, countermovement jumps, drop jumps and loaded jumps. Two versions of the isometric mid-thigh pull as well as an isometric squat are also covered in the course. Real-time data collection from the software is also shown as the athletes are performing the tests. A module on data analysis rounds out the course, which includes five metrics collected from the force plate, as well as calculations from this data, including relative strength index - modified, and dynamic strength index.

Spinal cord injury (SCI) is a result of disease or injury that results in the loss of sensory, motor, and autonomic function, or a combination of these functions below the level of injury. Research suggests that, along with medical treatment, exercise may aid in the maintaining of cardiovascular, muscular, and osteogenic health in individuals with an SCI. Practices, contraindications, special considerations, and general recommendations for whole-body cardiorespiratory and resistance exercise programming and progression for individuals with an SCI are discussed throughout.

Maximal force can be expressed across a range of conditions influenced by the external load and the time available to express force. As a result, several distinct and specific strength qualities exist. Conversely, some expressions of maximal force are similar and can be categorized as a single quality. Therefore, strength assessment systems must be sophisticated enough to isolate and measure each quality while minimizing redundant information. This article presents a contemporary, evidence-based and practical framework that reduces the many strength and speed-strength metrics into 5 distinct qualities. Alongside this, we present case examples of the application of strength diagnosis.
