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.

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.

The demanding and hazardous nature of firefighting necessitates a fitness testing framework that directly addresses the unique physiological challenges of the profession. This paper sought to identify gaps in the current fitness testing and training environment that are focused on cardiovascular, respiratory, muscular endurance, and muscular strength components of fitness and to advocate for a targeted, occupation specific fitness testing approach that aligns with the physiological challenges firefighters face. Ultimately, implementation of these plans should reduce the risk of injury and death and improve operational efficiency.

This is the NSCA’s Coaching Podcast, where strength and conditioning coaches share their experience, lessons learned, and advice about how to thrive in a highly competitive profession.

Dietary supplement use is quite prevalent among bodybuilders to enhance their physiques for competition. Many of the dietary supplements used by these athletes are neither safe nor effective. Several reviews have been published detailing the efficacy of dietary supplements for athletes; however, none have been written specifically for bodybuilders and physique athletes. Therefore, the aim of this article is to provide an evidence-based review of the top 5 dietary supplements for bodybuilding competitors: creatine, caffeine, protein powders, free-form essential amino acids, and beta-alanine. This review will provide bodybuilders, coaches, and practitioners with information on each supplement’s mechanism of action, seasonal benefits, protocol for use, and special considerations to optimize supplement strategies for performance, physique, and overall competitive success.

This course is an introduction to force plates and performance testing. This course covers the basics of setup and calibration of force plates, and then walks through several fundamental performance tests including squat jumps, countermovement jumps, drop jumps and loaded jumps. Two versions of the isometric mid-thigh pull as well as an isometric squat are also covered in the course. Real-time data collection from the software is also shown as the athletes are performing the tests. A module on data analysis rounds out the course, which includes five metrics collected from the force plate, as well as calculations from this data, including relative strength index - modified, and dynamic strength index.
