Multidirectional ground reaction forces (GRFs) and jump tests within baseball pitchers provide insight into athletic ability and coordination to produce lower-body force and power. Lower-body power is a biomechanical feature that denotes physiological capacity through dynamic and passive tissue stretch-shortening in transferring energy from the ground through the kinetic chain. Optimized lower-body power may lessen the magnitude of forces on the upper extremity. Insufficient lower-body power may create a greater risk of upper-body injury. Lower-body power and its relationship to ball velocity have been minimally investigated, yet some research points to a correlation between jumping ability and fastball velocity. Because pitching is unilateral, practitioners should consider unilateral jumps to determine the extent of bilateral asymmetry or stride to drive leg differences that can guide training to remediate deficiencies. The purposes of this brief review are to (a) examine factors that influence vertical jump performance among baseball players, (b) examine research on pitching multidirectional GRFs, and (c) examine literature concerning jump performances to baseball pitching performance. Collectively, this review can assist coaches and practitioners in lower-body power testing and training for baseball pitchers.

Falls resulting from trips are a leading cause of injury and can sometimes result in death, especially in the older population. Numerous researchers have studied the biomechanical mechanisms that differentiate fallers from nonfallers and determined whether training can beneficially impact those outcomes. Exercise and task-specific interventions have demonstrated fewer falls after trips but can be costly and often require specialized equipment, making their applicability less practical. Qualified health and fitness practitioners can develop evidence-informed, exercise-based programs focusing on 3 components (balance training, task-specific training, and resistance exercise). Such programs may help to reduce fall risk in older adults based on previously documented studies identifying the biomechanical demands of a successful fall arrest after a trip perturbation. These multicomponent programs should include a safe task-specific training element that does not require specialized equipment.

Agility is a key and complex concept within team sports performance. Because of its multidimensional nature, agility benefits from perceptual and cognitive skills as well as physical capacity (e.g., ability to exert acceleration, deceleration, and changes of direction). Agility should be integrated in different and complementary ways in team sports training. From more analytical to more ecological tasks, there is a need to comprehend the respective adaptations and identify how to integrate such a spectrum and, eventually, combine them in the training process and manage it accordingly to the player’s needs. Based on this premise, the purpose of this article is to present alternative methods and recommendations that may help to develop agility in field-based invasion sports. The main concepts pertaining to agility and associated capacities will be explored. Afterward, a proposal for a more analytical approach based on the use of cones and ladders will be introduced, as well as approaches based on small-sided games. Finally, an integration of agility training and a combination of approaches will be presented using soccer as an example.

The 3-minute all-out exercise test (3MT) was developed over a decade ago and enables the estimation of time for onset of momentary fatigue for a given speed or power output exceeding critical speed (CS) or critical power (CP), respectively. The 3MT has been validated for conducting high-intensity interval training, used with load carriage prediction and prescription, and validated for shuttle running. These prescriptions are novel because they allow for standardizing exercise intensities relative to metabolic parameters as opposed to a percentage of a given maximum or reserve. Research was identified using leading search engines (e.g., PubMed, Google Scholar, and Research Gate) and citations to similar articles. The objective of this review article was to summarize research that emerged on the CS/CP concept with emphasis on applications since the advent of the 3MT. The review concludes with application of the CS/CP concept to the frequency, intensity, time, and type of exercise for exercise prescription.
