Acute physiological responses and performance following subsequent CrossFit ‘CINDY’ workout with Zea Mays juice

Abstract

Purpose: The purpose of this study was to investigate the physiological responses and performance following subsequent repeated high intensity exercise with consumption of Zea may juice ( ZM ) Materials: Total of seventeen participants involved in the study. They were physically active who had cardio and strength training at least 3 times per week. The age of participants was 21.8±1.7 years old, body weight 65.4±11.2 kg and height 169.7±7.2 cm. Crossfit ‘CINDY’ exercise were repeated between two hours of rest. Treatment beverage of ( ZM ) juice vs Carbohydrate-electrolyte (CE) drinks were consumed immediately after exercise in double blind cross over manner. Number of complete set of exercise, heart rate, blood lactate and rate of perceived exhaustion (RPE) were recorded at the end of each exercise session. Results: Total number of complete ‘CINDY’ exercise significantly increased in ZM juice group during second bout of exercise compared to CE drink group. There were no significant difference in heart rate, blood lactate and RPE in both groups Conclusions: ZM juice has potentials an alternative recovery beverage to promote subsequent repeated exercise within short rest time.

Characterization of Hormonal, Metabolic, and Inflammatory Responses in CrossFit® Training: A Systematic Review

“…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 ).…”

“…The studies that described the training protocols analyzed participants who performed different combinations of multiple types of exercise modalities. CV, gymnastic and weightlifting exercises): gymnastic ( n = 2; Shaw et al, 2015 ; Ahmad et al, 2019 ), G + W ( n = 4; Fernandez-Fernandez et al, 2015 ; Escobar et al, 2016 , 2017 ; Timón et al, 2019 ), CV + weightlifting ( n = 6; Perciavalle et al, 2016 ; Kliszczewicz et al, 2017 , 2018a , b ; Coco et al, 2019 ; Feito et al, 2019a ), and CV + gymnastic + weightlifting ( n = 9; Tibana et al, 2016 , 2018 , 2019a , b ; Maté-Muñoz et al, 2017 , 2018 ; Durkalec-Michalski et al, 2018 ; Mangine et al, 2018 , 2019 ).…”

“…Nineteen studies (Fernandez-Fernandez et al, 2015 ; Murawska-Cialowicz et al, 2015 ; Shaw et al, 2015 ; Escobar et al, 2016 , 2017 ; Perciavalle et al, 2016 ; Tibana et al, 2016 , 2018 , 2019a ; Kliszczewicz et al, 2017 , 2018a ; Maté-Muñoz et al, 2017 , 2018 ; Durkalec-Michalski et al, 2018 ; Ahmad et al, 2019 ; Cadegiani et al, 2019 ; Coco et al, 2019 ; Feito et al, 2019a ; Timón et al, 2019 ) investigated metabolic responses (see Table 2 ). The metabolic variables analyzed were lactate (Fernandez-Fernandez et al, 2015 ; Murawska-Cialowicz et al, 2015 ; Shaw et al, 2015 ; Escobar et al, 2016 , 2017 ; Perciavalle et al, 2016 ; Tibana et al, 2016 , 2018 , 2019b ; Maté-Muñoz et al, 2017 , 2018 ; Durkalec-Michalski et al, 2018 ; Kliszczewicz et al, 2018a ; Ahmad et al, 2019 ; Cadegiani et al, 2019 ; Coco et al, 2019 ; Feito et al, 2019a ; Timón et al, 2019 ), glycemia (Shaw et al, 2015 ; Perciavalle et al, 2016 ; Tibana et al, 2016 ; Kliszczewicz et al, 2017 ; Durkalec-Michalski et al, 2018 ; Cadegiani et al, 2019 ; Coco et al, 2019 ; Timón et al, 2019 ), cholesterol (Shaw et al, 2015 ), creatinine (Cadegiani et al, 2019 ), GOT and GPT (Timón et al, 2019 ).…”

“…However, blood lactate responses after the protocols were similar regardless of the WOD time. The values presented were 10.15–18.38 mmol·L −1 for protocols with a time <10 min (Maté-Muñoz et al, 2017 , 2018 ; Kliszczewicz et al, 2018a ; Tibana et al, 2018 ; Timón et al, 2019 ), 5.95–16.56 mmol·L −1 for protocols with a time ranging from 10 to 19 min (Maté-Muñoz et al, 2017 , 2018 ; Kliszczewicz et al, 2018a ; Tibana et al, 2018 ; Timón et al, 2019 ) and 11.79–17.43 mmol·L −1 for protocols ≥20 min (Fernandez-Fernandez et al, 2015 ; Maté-Muñoz et al, 2017 , 2018 ; Ahmad et al, 2019 ; Tibana et al, 2019b ). The values presented were 6.34–14.0 mmol·L −1 for studies that did not report the duration of the protocols (Fernandez-Fernandez et al, 2015 ; Perciavalle et al, 2016 ; Tibana et al, 2016 ; Coco et al, 2019 ).…”
