“…This difference might come from the training protocol that we applied and the period. Shaw et al (2015), it was reported that there were not significant difference in one session Crossfit training, systolic blood pressure (p=0.450) and diastolic blood pressure (p=0.844) (Shaw, Dullabh, Forbes, Brandkamp, & Shaw, 2015). The significant difference in both systolic and diastolic blood pressure of our study may be result of the regular application of the program during 12 weeks.…”

Aim: Group-based training through Crossfit has recently exploded in popularity. When the effects of Crossfit trainings on many basic component are considered, the aim of this study is to investigate the effects of high-intensity functional trainings on anthropometric and physiological characteristics of sedentary individuals. Methods: Their age averages are 23.62±5.39 (year), height averages are 177±0.06 (cm) and body weight averages are 79.88±12.14 (kg). Crossfit training system was applied during highintensity functional exercise planning at four days a week, for twelve weeks. Body weight, body fat percentage, body mass index (BMI), blood pressure, resting heart rate, hand grip strength, back strength, leg strength measurements were taken from the participants. Statistical analyses were done with SPSS 15.00 statistical package program. Results: In pre-test and post-test measurements, it was found that there are statistically significant differences between the participants' body fat percentage, systolic blood pressure, diastolic blood pressure, left and right-hand grip, back strength and leg strength values (p<0.05). Conclusion: As a result, it can be said that these high-intensity exercises that were applied has positive contribution to anthropometric and physiological characteristics in sedanteries.

“…It is worth noting that expired gases were not collected during the experimental sessions, and VO2 was calculated using a regression equation for each subject based on heart rate data. Another study by Shaw et al (Shaw, Dullabh, Forbes, Brandkamp, & Shaw, 2015) noted significant increases in heart rate and blood lactate levels as well. At present, no data exits documenting VO2 collected during CrossFit performance.…”

CrossFit is a physically and metabolically-demanding training mode increasing in popularity among recreational athletes. Presently, however, scarce evidence is available documenting its energetic profile. This study investigated the metabolic characteristics of a CrossFit training bout as measured by expired gases and blood lactate. Eleven females and 7 males completed a 12-minute CrossFit bout on two occasions separated by three days. During both experimental sessions (Pt1, Pt2), subjects performed as many rounds as possible (AMRAP) within the timed workout which consisted of consisted of 12 box jumps (30" for males, 20" for females), 6 thrusters (24 kg for males, 16 kg for females), and 6 bar-facing burpees in sequence. Oxygen consumption (VO2), respiratory exchange ratio (RER), blood lactate (BL), and repetitions completed were measured during both experimental sessions. The average VO2 and RER of both bouts (Pt1 and Pt2) was 37.0 ± 4.8 ml/kg/min and 1.04 ± 0.1, respectively. Average BL significantly increased above pre-exercise concentrations (3.0 ± 1.3 mmol/L) at 4 min (10.1 ± 3.2 mmol/L; p < 0.01), 8 min (12.3 ± 3.5 mmol/L; p < 0.01), and immediately post at 12 min (12.6 ± 3.9 mmol/L; p < 0.01). Repetitions completed in Pt2 (140.2 ± 25.9) were significantly different to repetitions completed in Pt1 (131.2 ± 27.2) (p = 0.023). Average repetitions completed in Pt1 and Pt 2 was 135.7 ± 26.6. These data suggest that CrossFit is a metabolicallydemanding conditioning method that relies heavily on both aerobic and anaerobic energy production and may represent an alternative to traditional methods of exercise to improve fitness and longevity.

“…The training intensity was verified in a few studies through heart rate (HR) assessment, in which the HR remained between 85.9 and 97.4% of the maximum HR (Fernandez-Fernandez et al, 2015 ; Murawska-Cialowicz et al, 2015 ; Kliszczewicz et al, 2018a , b ; Maté-Muñoz et al, 2018 ; Tibana et al, 2018 ; Ahmad et al, 2019 ; Feito et al, 2019a ). Regarding the WOD time, 10 studies used protocols with times <10 min (Fernandez-Fernandez et al, 2015 ; Kliszczewicz et al, 2017 , 2018a , b ; Maté-Muñoz et al, 2017 , 2018 ; Mangine et al, 2018 , 2019 ; Tibana et al, 2018 ; Timón et al, 2019 ), 13 studies used protocols with times between 10 and 19 min (Murawska-Cialowicz et al, 2015 ; Shaw et al, 2015 ; Escobar et al, 2016 , 2017 ; Kliszczewicz et al, 2017 , 2018a , b ; Maté-Muñoz et al, 2017 ; Durkalec-Michalski et al, 2018 ; Mangine et al, 2018 , 2019 ; Tibana et al, 2018 ; Feito et al, 2019a ), and five studies used protocols with times over 20 min (Fernandez-Fernandez et al, 2015 ; Maté-Muñoz et al, 2017 , 2018 ; Mangine et al, 2018 ; Tibana et al, 2019b ).…”

Background: CrossFit® training is a high-intensity functional training program that aims to increase physical functional performance through biochemical responses, i.e., hormonal, metabolic, and inflammatory responses. Most hormonal, metabolic, and inflammatory changes induced by CrossFit® training have been reported in isolated clinical studies. The purpose of this review was to systematically explore the existing literature on characterization of hormonal, metabolic, and inflammatory responses resulting from CrossFit® training. Methods: A systematic search of the literature was conducted in PubMed, Web of Science and Scopus from August 2019 to October 2019. Studies were selected through critical review of the content. Using specific keywords, 623 articles were found, of which 597 were excluded for ineligibility, and 25 were eligible. The papers were separated according to subject area: hormonal ( n = 8), metabolic ( n = 19), and inflammatory ( n = 6) changes. All were published between 2015 and 2019. Results: This review reveals potential effects of CrossFit® training on hormonal, metabolic, and inflammatory responses. However, studies had low levels of evidence and reliability due to methodological limitations. Conclusion: In summary, the results showed a greater volume and intensity of workouts accentuate the responses, that are of paramount importance for improving understanding of the effects of CrossFit ® training and serve as a basis for prescribing future exercise protocols.
