“…In contrast to these studies, our findings show that there are significant associations between aerobic (i.e., VO 2max ) and anaerobic capacity (i.e., peak power), in addition to whole-body muscular strength, with work capacity performance. Findings from Bellar et al [21] support these associations as they also show aerobic and anaerobic capacity relate to select modes (i.e., WOD selection and/or style) of work capacity performance. One reason for these differences in association could be the homogeneity of the respective study populations.…”

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.

“…CrossFit is a sport that includes a wide variety of generally short-duration, high-intensity exercises ranging from Olympic weight lifting to rowing exercises. Performance in this sport is highly dependent on peak power and fatigue resistance [12]. As such, dietary nitrate may be beneficial for CrossFit athletes.…”

BackgroundWhile it is well established that dietary nitrate reduces the metabolic cost of exercise, recent evidence suggests this effect is maintained 24 h following the final nitrate dose when plasma nitrite levels have returned to baseline. In addition, acute dietary nitrate was recently reported to enhance peak power production. Our purpose was to examine whether chronic dietary nitrate supplementation enhanced peak power 24 h following the final dose and if this impacted performance in a heavily power-dependent sport.MethodsIn a double-blind, randomized, crossover design, maximal aerobic capacity, body composition, strength, maximal power (30 s Wingate), endurance (2 km rowing time trial), and CrossFit performance (Grace protocol) were assessed before and after six days of supplementation with nitrate (NO) (8 mmol·potassium nitrate·d−1) or a non-caloric placebo (PL). A 10-day washout period divided treatment conditions. Paired t-tests were utilized to assess changes over time and to compare changes between treatments.ResultsPeak Wingate power increased significantly over time with NO (889.17 ± 179.69 W to 948.08 ± 186.80 W; p = 0.01) but not PL (898.08 ± 183.24 W to 905.00 ± 157.23 W; p = 0.75). However, CrossFit performance was unchanged, and there were no changes in any other performance parameters.ConclusionConsuming dietary nitrate in the potassium nitrate salt form improved peak power during a Wingate test, but did not improve elements of strength or endurance in male CrossFit athletes.

“…In this line of research, Butcher (17) conducted a study with CF Regionals and Open level competitors where he showed that performance in tests such as VO2max and Wingate were not correlated with performance in standard CF workouts, although correlation between Fran and Grace (CF's most common benchmark routines) and whole-body strength (1RM tests in specific exercises) tests was reported. In a study of 32 trained individuals, separated in two groups, with and without CF experience, Bellar (18) , found similar results.…”

Background:CrossFit is a functional training modality created by Greg Glassman in 1995 in the United States. Such modality is characterized by the execution of complex and high intensity movements with the purpose of preparing the participant for the unpredictable. It is observed the exponential increase in CrossFit practice across the world, with this increase there are a consolidation of this modality with as a very peculiar sport modality, since as tasks to be performed in the competitions are made public just before the events happen. Few studies have focused on the determinants of competitive success in CrossFit, both morphologically and performance.Objective: This present study dedicated to investigate, in the existing literature and in the results of the 2016 championship, variables that can be predicted the performance of these athletes. Methods: The performance of 40 2016 -CrossFit Games finalists of both genders were analyzed in the morphological variables (weight, height, body mass index), performance and specific tests (Benchmarks and 1 MR tests). Results: We found that among male athletes, it was not possible to identify variables that could predict a classification. However, among the women, we identified some variables that correlated with classification, such as the Benchmark Filth 50, Sprint performance of 400m and maximal loads in the Clean and Jerk and Snatch exercises. Conclusion: It was attributed to the correlations found among women the smaller participation in the Games, this allowed physical characteristics as force to influence in the final position.
