This article consists of five assessments that could be utilized by the tactical facilitator to measure upper- , lower- , and total-body power in law enforcement officers (LEOs). Although the focus of this article is LEOs, the assessments could also be used for other tactical populations.
Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
This Kinetic Select from NSCA’s Essentials of Personal Training, Second Edition gives a brief overview of respiratory adaptations, and how aerobic interventions of duration and intensity can be used for specific adaptations for endurance training.
