“…Due to the physical demands of various “tactical athlete” populations (e.g., military, fire service, etc. ), training needs have changed and adapted over time, with a clear “grass-roots” interest in and demand for improving fitness for job duties, and law enforcement (i.e., combat, fire suppression and rescue) [ 37 ]. For example, there has been a shift to the development and use of both combat readiness tests in the military and physical agility tests used in the fire service and law enforcement, which mimic actual job-related tasks rather than traditional fitness tests, which typically include a run, bodyweight exercises (e.g., sit-ups and push-ups), and a flexibility measure [ 38 ].…”

High-intensity functional training (HIFT) is an exercise modality that emphasizes functional, multi-joint movements that can be modified to any fitness level and elicit greater muscle recruitment than more traditional exercise. As a relatively new training modality, HIFT is often compared to high-intensity interval training (HIIT), yet the two are distinct. HIIT exercise is characterized by relatively short bursts of repeated vigorous activity, interspersed by periods of rest or low-intensity exercise for recovery, while HIFT utilizes constantly varied functional exercises and various activity durations that may or may not incorporate rest. Over the last decade, studies evaluating the effectiveness of HIIT programs have documented improvements in metabolic and cardiorespiratory adaptations; however, less is known about the effects of HIFT. The purpose of this manuscript is to provide a working definition of HIFT and review the available literature regarding its use to improve metabolic and cardiorespiratory adaptations in strength and conditioning programs among various populations. Additionally, we aim to create a definition that is used in future publications to evaluate more effectively the future impact of this type of training on health and fitness outcomes.

“…HIFT challenges physical work capacity through four mechanisms: (1) by addressing multiple fitness domains (e.g., aerobic and resistance training) [9], (2) in emphasizing functional exercises that require universal motor patterns (e.g., pushing and squatting) [10], (3) by temporally combining aerobic and resistance training elements within exercise sessions [11,12], and (4) with consistent focus on high effort or intensity [8]. Further, these mechanisms are incorporated into training sessions in variable patterns across multiple time domains (i.e., short and long durations), creating a unique stimulus virtually every day.…”

High-Intensity Functional Training (HIFT) is a novel exercise intervention that may test body systems in a balanced and integrated fashion by challenging individuals’ abilities to complete mechanical work. However, research has not previously determined if physical work capacity is unique to traditional physiologic measures of fitness. Twenty-five healthy men and women completed a six-week HIFT intervention with physical work capacity and various physiologic measures of fitness assessed pre- and post-intervention. At baseline, these physiologic measures of fitness (e.g., aerobic capacity) were significantly associated with physical work capacity and this relationship was even stronger at post-intervention assessment. Further, there were significant improvements across these physiologic measures in response to the delivered intervention. However, the change in these physiologic measures failed to predict the change in physical work capacity induced via HIFT. These findings point to the potential utility of HIFT as a unique challenge to individuals’ physiology beyond traditional resistance or aerobic training. Elucidating the translational impact of increasing work capacity via HIFT may be of great interest to health and fitness practitioners ranging from strength/conditioning coaches to physical therapists.

“…The variety in a training program dictates the athlete's general physical preparedness. Improving anaerobic and aerobic capacity will allow the athlete to excel in all aspects of performance as opposed to suffering from training decrements (Haddock et al, 2016). The improvement of the anaerobic threshold in skiers and rowers is linked to the nature of their training regimens.…”

Ergometers have been developed as off-season or dryland training tools for sports such as rowing and crosscountry skiing. These ergometers have recently been staples in the training methods for functional fitness athletes. Purpose: To examine the relationship between athlete strength and power with rowing ergometer and ski ergometer performance. Methods: Eight healthy college-aged participants, age 18-26 years volunteered to go through a series of strength and ergometric exercises while being assessed with a metabolic cart to measure gas exchange. The three strength measures were a maximal effort on bench press, back squat, and deadlift. A watt bike was also used to assess lower body power output. All strength tests were performed following the National Strength and Conditioning Association protocols. The ergometric performances on ski ergometer and rower were performed both using the Concept2 model with the damper settings at 10. Results: A significant relationship exists between strength and ergometer performance at both sprint and mid-distances. Conclusions: Athlete strength is a significant contributor to ski ergometer and rowing ergometer performance at 100-meter and 2000-meter performances. When considering training protocols for rowing and crosscountry skiing, athletes and coaches should invest in addressing strength as a meaningful portion of the training effort. Contribution/Originality: The paper's primary contribution is finding the relationship athlete strength and power have with ergometer performance.
