Do interlimb asymmetries impact performance and what are some training programs to reduce them?

The strength and conditioning profession involves combined competencies for the application of sport/exercise science, administration, management, teaching, and coaching. Its professionals must also comply with various laws and regulations while responding to instances of potential injury, and related claims and suits. This creates remarkable challenges, and requires substantial experience, expertise, and other resources to effectively address them, especially in multi-sport (e.g., collegiate and scholastic) settings.

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 article contains examples of how to periodize training programs to help aerobic endurance athletes reach their peak condition at the appropriate time of the year.

This article highlights four non-traditional calf exercises that can immediately be used in strength programs for improving calf strength while also increasing ankle dorsiflexion mobility.

Athletes must be able to express strength, power, and speed in multiple directions, and it may be beneficial to emphasize horizontally based movements in strength and conditioning programs.

CASCE accreditation is chosen by programs looking to be seen as a leader in strength and conditioning education.

The National Strength and Conditioning Association (NSCA) recognizes and supports the premise that many of the benefits associated with adult resistance training programs are attainable by children and adolescents who follow age-specific resistance training guidelines.

The NSCA Education Recognition Program (ERP) recognizes regionally accredited academic institutions for their educational programs that have met, and continue to meet, educational guidelines recommended by the NSCA. ERP recognitions are good for three years and schools are eligible for renewal following this three-year period.
