Artigo a ser publicado envolvendo uchi-komi intermitente em alta intensidade

Depois de um ano para ser rejeitado em outra revista, sairá em outra com FI maior. E depois dizem que uma das premissas da ciência é a lógida : )

Notem que as unidades saíram sem o -1. Acho que apagaram na edição final hahahaha

Tb tenho uma dúvida: no lattes, coloco em aceito como indica o CNPq ou faço como meus nobres colegas que colocam em publicado sempre com a mesma paginação (p.1-9)?

Abstract

ABSTRACT: The objective of the present study was to compare the physiological and performance responses to different judo techniques and time structure uchi-komi (technique entrance) protocols. Ten judo athletes (25±6 years old, 73±9 kg, 173±5 cm, and 15±6 years of judo experience) were submitted to nine all-out uchi-komi sessions. Three techniques (o-uchi-gari, seoi-nage, and harai-goshi) and three different time structures (18x10s/10s, 9x20s/20s, and 6x30s/30s) were randomly assigned. Two-way and three-way ANOVA with repeated measurements and the Bonferroni test were used. The significance level was fixed at 5%. There was no effect of the time structure or the technique on the absolute energy expenditure (P > 0.05), which can be attributed to the all-out characteristic of the exercise. However, more repetitions were executed during the o-uchi-gari protocol (F = 19; P < 0.001; η = 0.32) compared to harai-goshi and seoi-nage (P < 0.001 for both comparisons). Oxygen consumption differed over time during the activity (F = 767; P < 0.001; η = 0.904), with lower values during the 1 min (32.51 ± 3.21 mL.kg.min) compared to the 2 (41.47 ± 4.20 mL.kg.min) and 3 minutes (42.96 ± 4.29 mL.kg.min), and lower values were recorded in the 2 min compared to the 3 min (P < 0.001 for all comparisons). There was also an effect of technique on the total energy expenditure per repetition (F = 6; P = 0.001; η = 0.128), with o-uchi-gari resulting in lower values compared to seoi-nage (P = 0.003), as the former technique does not involve torso rotation and knee flexion, while the latter technique does. These training protocols resulted in similar oxygen uptake and heart rate responses compared to match simulations, and they can be used to simulate the match demand.
