Mark Stephenson explains the systems of stress response for tactical personnel and the cognitive influence on decision-making and reaction time.

Deloading is a period of reduced training stress where training demand is intentionally reduced to mitigate physiological and psychological fatigue and promote recovery. A deload is commonly implemented to enhance readiness for subsequent training and occurs between or during training phases. During a deload, training is typically modified by reducing the intensity of effort, training volume, duration, or frequency. Adjustments in exercise selection are based on recovery goals and the specific demands of the athlete’s training. Deloads are commonly preplanned and implemented into the training program every 4–8 weeks based on the structure of the training cycle and recovery needs. Alternatively, deloads are sometimes applied reactively using an autoregulatory approach to accommodate unexpected fatigue or performance decrements. While deloading shares conceptual similarities with tapering and training cessation, it should be differentiated based on its objective, structure, and positionality with the overall training program. The purpose of this article is to describe the current research landscape, propose areas for future research, and to provide broad practical recommendations for implementing deloading within the strength and physique sports training program.

Interlimb asymmetries have been recently investigated in athletic populations. However, the effects of training interventions on interlimb asymmetries have been scarcely examined. Therefore, the aim of this study was to determine the effects of training interventions on changes in interlimb asymmetries from pre- to post-training. Furthermore, to examine the effects of training programs on intervention groups compared with control groups. A database search was completed (MEDLINE, CINAHL, and SPORTDiscus). Eight studies were then included in the meta-analysis. Results showed small reductions in interlimb asymmetries in single-leg broad jump (SLBJ) and change of direction (COD) speed from pre- to post-training interventions, whereas moderate effects were found in single-leg countermovement jump (SLCMJ) and SL lateral jump. When comparing the training interventions with the control groups, results showed small effects in favor of the training groups for reducing interlimb asymmetries in SLBJ and large effects in SLCMJ and COD speed. Thus, training interventions can evoke small to moderate reductions in interlimb asymmetries from pre- to post-training programs. Strength training performed unilaterally or bilaterally may elicit these reductions. Furthermore, training interventions showed larger effects compared with the control groups in reducing interlimb asymmetries. However, further research is needed.

Various methods of eccentric training that aim to increase muscle mass or reduce ground contact time during a landing task have been extensively researched and practically examined. However, multiple methods to implement eccentric training currently exist; they differ in execution and intended training adaptions. There is a clear differentiation between an eccentric muscle action and an eccentric motion whereby a motion alludes to a downward movement of an exercise. The proposed eccentric motions are dissipating eccentrics, deceleration eccentrics, overcoming eccentrics, maximal eccentrics, and rebound eccentrics. These motions formulate into training methods and cues to allow practitioners to clearly differentiate the various eccentric training methods used in research and practice. This review proposes a new conceptual framework that clearly outlines the different forms of eccentric motions that fall into a desired eccentric training method.
