Puberty is a critical period for young athletes, characterized by significant physical, psychological, and social changes. During puberty, young athletes experience the adolescent growth spurt at the same time as intensified training regimens, which can affect performance, injury risk, and overall health. Systematic training can improve physiological and performance outcomes, but the increased training volume and changes to the body during adolescence can also heighten the risk of injuries. This article discusses the injury risks associated with adolescent growth and provides comprehensive recommendations to mitigate these risks. Key recommendations include limiting training hours to the athlete’s age, monitoring growth and maturation to adjust training loads and content, and incorporating and modifying consistent strength and conditioning prescriptions. In addition, optimal nutrition, sleep, and interdisciplinary planning among coaches, parents, and stakeholders should be emphasized to support young athletes’ holistic development and well-being during the adolescent growth spurt.

Athletes engage in training programs that develop physical and physiological attributes to improve performance over time. However, ensuring athletes are optimally prepared just before competition is also of utmost importance. Indeed, such approaches may often adopt 1 or more strategies in the days, hours, and minutes preceding competition, including exercise priming, active warmup, and/or postactivation performance enhancing (PAPE) activities. Despite a plethora of discrete research, such information seems poorly synthesized, making it difficult for coaches and athletes to implement optimal evidence based physical preparation approaches in many sporting contexts. This article aims to provide a scoping overview of evidence, facilitate discussion, and where possible, propose practical exercise based recommendations that may be useful leading up to (~48 hours–~1 minute) tasks with a short or prolonged endurance component or requiring repeated intermittent efforts (e.g., team based field sports). Well-timed and –designed activities can facilitate several aspects of physical performance, potentially improve athletes’ psychological state(s) and mental preparedness. The benefits of a warm-up are most well documented, but priming and PAPE strategies also warrant consideration. It is intended that the evidence and suggestions presented will be useful for strength and conditioning professionals preparing athletes for competition.

A common obstacle to achieving recommended physical activity and desired training goals is time. This is true for recreationally trained adults and athletes, particularly at the collegiate level, where greater restrictions on practice time and training are in place. One possible solution is to implement time-saving and time efficient training routines and methods that may limit the amount of time needed to attain desired physiological adaptations—by decreasing the time needed to train and/or by increasing the frequency with which brief workouts are completed throughout the week (e.g., “microdosing”). To provide the most optimal training stimulus, the correct method must be used. Unfortunately, numerous terms describe routines and methods discussed in the current body of available literature, many of which may seem similar and lead to confusion. The purpose of this article is to outline the similarities and differences of the numerous timesaving and time-efficient training routines and methods. Ultimately, this article synthesizes the current research into practical recommendations as programming options for strength and conditioning coaches and personal trainers. The information provided may also serve as a foundation for future research opportunities in time-saving and time-efficient training.

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.

This review analyzes relevant variables involved in acute interference effects of concurrent training (CT) sessions of aerobic exercise followed by strength exercises. The aerobic exercise intensity, mode, volume, duration of recovery interval between exercises, muscle groups involved, and utilization of ergogenic aids are the variables identified in this review. High-intensity interval aerobic exercises result in more pronounced negative effects on strength-endurance exercise but not in maximal strength. Cycling results in more negative effects on strength endurance performance exercise than running. A 4-hour to 8-hour recovery interval seems to be enough to avoid interference on strength-endurance performance. Reduction in strength-endurance performance is located in muscle groups involved in both exercises. Low aerobic exercise volume (3 km) with; 18 minutes of duration does not diminish strength endurance, whereas higher volumes (5 and 7 km) with ;30 and ;42 minutes of duration, respectively, generate impairments. Caffeine, carbohydrate, and beta-alanine are not able to revert the deleterious effect on strength-endurance performance, whereas creatine and capsaicin analog supplementation are. Thus, these variables must be taken into consideration to prescribe and organize a CT session. This information may help coaches to organize exercise sessions that minimize or avoid the impairment in strength performance after aerobic exercises.

Hybrid fitness competitions such as HYROX have rapidly gained popularity, blending aerobic endurance running with a variety of high-intensity resistance and ergometer-based stations in a globally standardized format. The sport’s unique structure, comprising eight 1-kilometer runs interspersed with diverse workload stations, presents distinct physiologic, biomechanical, and technical demands. This review synthesizes existing research on hybrid fitness events to identify the key determinants of HYROX performance, emphasizing aerobic capacity, anaerobic power, local muscular endurance, and maximal strength. The aerobic system is foundational, enabling recovery between high-intensity efforts and sustaining performance during the event’s prolonged duration. Conversely, anaerobic capacity is critical for executing the high-intensity efforts demanded by each fitness station. Local muscular endurance supports repeated submaximal contractions, while strength and power underpin performance in movements such as sled pushes and running economy. Technical proficiency and injury prevention strategies are also discussed, alongside targeted programming recommendations, including high-intensity interval training, circuit training, and blood flow restriction methods. Despite its growing popularity, limited sport-specific research exists, necessitating further investigation to refine training and performance strategies. This review provides a comprehensive framework for athletes and coaches to optimize preparation and performance in HYROX, contributing to the broader understanding of hybrid fitness competitions.
