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.

Time-restricted eating (TRE) is an application of intermittent fasting where an individual consumes their calories in a specific eating window (e.g., 8 hours) followed by a prolonged fasting window (e.g., 16 hours). Several randomized controlled trials have analyzed the combined effect of resistance training (RT) and TRE on physical adaptations, including fat mass (FM) loss, fat-free mass (FFM) retention, hypertrophy, local muscular endurance, power, and strength. In this mini review, we highlight the methodology and results from these studies and conclude by providing practical application suggestions for fitness professionals striving to maximize RT + TRE with their clientele. Generally, RT + TRE leads to positive body composition changes, including FM loss and FFM retention, which culminates in improved body fat percentage. Similarly, RT + TRE consistently stimulates positive neuromuscular adaptations, such as increased hypertrophy, local muscular endurance, power, and strength. When positive changes are not observed, and when safely implemented, RT + TRE rarely confers negative effects on the abovementioned adaptations. In short, RT + TRE may be a beneficial dietary and exercise strategy to improve body composition and muscular fitness. However, there are several caveats for practitioners to consider, which are discussed at length in this article.

The NSCA-CPT Techniques of Exercise Online Practice Question Bundle helps candidates get familiar with the type, scope, and difficulty of the questions on the NSCA-CPT Certification exam.

Spinal cord injury (SCI) is a result of disease or injury that results in the loss of sensory, motor, and autonomic function, or a combination of these functions below the level of injury. Research suggests that, along with medical treatment, exercise may aid in the maintaining of cardiovascular, muscular, and osteogenic health in individuals with an SCI. Practices, contraindications, special considerations, and general recommendations for whole-body cardiorespiratory and resistance exercise programming and progression for individuals with an SCI are discussed throughout.

From the 2021 Personal Training Virtual Conference, Andrea Leonard thoroughly details the impact of various cancer surgeries on muscle balance and range of motion and necessary program considerations. She also discusses the acute and chronic side-effects of cancer treatment and how they may affect exercise programming. Another area that is highlighted is lymphedema. She details the cancer-related risk factors and how it can be prevented and/or managed with proper exercise programming and progression.

Adequate nutrition generally promotes training adaptations and thus optimal performance. Adolescence is characterized by a pubescence growth spurt, increasing energy and nutrient needs. Most team sports literature focuses on male athletes, with little on adolescent female team sports. Adolescent female athletes are at an increased risk of inadequate energy, and micronutrient intakes because of the pursuit of high fitness levels, and society pressures. This may cause hormonal irregularities, delayed development, poor bone health, and increased risk of injury. This review synthesizes information on the nutritional needs of adolescent female team sport players for performance and health.

A significant number of resistance training injuries occur at the shoulder complex. However, there is a lack of research identifying predictive variables, which may increase the risk of these injuries. Certain exercises, such as those requiring the apprehension position (glenohumeral abduction with external rotation), have been investigated and found to be associated with shoulder pain and injury. However, there are additional exercises or positions that may also be associated with increased injury risk. The position of end-range glenohumeral extension, particularly as it pertains to a dip, is a vulnerable position that may have previously been overlooked.

Verbal cues are tools used by practitioners in developing a youth athlete’s motor skill abilities. External cues may optimize athletic performance and movement competencies in adults with trends for youth athletic populations following suit. However, maturation, training age, and cognitive age may interact with the efficacy of cues used. To better assist practitioners working with youth, this article reviews current empirical evidence on how youth populations respond or may respond to cues and offers practical applications.

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.
