This excerpt from Developing Endurance goes over tapering and peaking in aerobic training for competition.

This episode recaps one of the sessions from the 2022 NSCA Coaches Conference in San Antonio, TX. Head Coach and Assistant Athletic Director for Athletic Performance at the University of Texas, Donnie Maib, discusses “the Golden Connection” as it relates to working with rotational athletes. Tune in as Coach Maib shares stories with NSCA Coaching and Sport Science Program Manager, Eric McMahon, on lessons learned from a 27-year collegiate strength and conditioning career, including paths for aspiring coaching, being a good father and husband, and areas of the field he sees on the near horizon.

Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.

Various aspects of resistance training, such as specific exercises chosen, workout structure, resistance used, volume (repetitions and sets), rest intervals between sets, and training frequency, can be manipulated to mold the strength training program to best meet an endurance athlete’s goals.

The private sector is growing, and so is the competition. With low barriers to entry and clients cycling in and out of programs, you need a strong business strategy to stand out and build staying power. Gini Grimsley draws on her experience across commercial fitness and National Strength and Conditioning Association (NSCA) leadership to address top questions coaches are asking: Where is the smartest place to start? How do you set your rates? How do you grow a client base in a new community? Grimsley distinguishes between being certified and being qualified, noting credentials open the door while applied experience takes you further. She introduces a framework for “periodizing your paycheck,” reverse-engineering income goals into a viable revenue model. Grimsley also outlines how to integrate into established communities and balance hybrid in-person and online coaching. If you are exploring the private sector or refining your approach, gain practical strategies to find your niche and achieve career flexibility.

The physiological response to breath holding includes bradycardia and peripheral vasoconstriction, which contrasts with that of exercise which includes tachycardia and peripheral vasodilation. This raises the question as to what the physiological response is to breath holding during exercise. During low-intensity exercise, the breath holding response of bradycardia and peripheral vasoconstriction prevails over the exercise response of tachycardia and peripheral vasodilation, but nevertheless the exercise may be sustained. Due to the lack of availability of extrinsic oxygen (O 2 ) from the atmosphere during breath holding, the energy demands can be met by increased reliance on intrinsic O 2 stores (i.e., O 2 that was in the body before the breath hold) via increased O 2 extraction at the muscle compared with exercise while breathing, or increased contributions from anaerobic energy systems. During high intensity exercise of short duration, the exercise response may prevail over the breath holding response due to the increased parasympathetic withdrawal and sympathetic drive of higher intensity exercise. If breath holding during high-intensity exercise was sustained for long enough, the breath holding response may eventually overcome the exercise response, although this may be difficult due to the inverse relationship between exercise intensity and breath hold duration.

Exercise is increasingly recognized as an effective, nonpharmacological approach for managing both acute and chronic pain. However, accurate pain assessment methods tailored to different exercise settings and populations are essential. This review evaluates existing pain assessment techniques, highlighting self-report measures such as the Visual Analog Scale and Numerical Rating Scale, as well as quantitative measures, such as Pressure Pain Threshold and Conditioned Pain Modulation. These techniques provide valuable insights into the neurophysiological mechanisms behind pain reduction. Although exercise commonly produces a temporary reduction in pain sensitivity known as exercise-induced hypoalgesia (EIH), the effectiveness of this response depends on various factors, such as exercise intensity, psychological state, and pre-existing pain conditions. In addition, exercise itself can sometimes lead to short-term discomfort due to muscle fatigue or delayed-onset muscle soreness. This review offers strength and conditioning providers, as well as researchers, a clear framework for (a) selecting appropriate pain assessment tools, (b) designing research protocols, and (c) customizing exercise interventions for specific populations and pain conditions. By examining self-report and quantitative assessment techniques, along with considerations for data analysis and practical application, this review helps strength and conditioning professionals interpret the literature surrounding EIH and apply practical pain monitoring strategies to guide training and recovery in various populations.

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.

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.
