“…That is, during exercise, with the increase in HR, autonomic dysfunctions occur such as vagal inhibition and increased sympathetic activation ( Buchheit et al, 2009 ). This post-exertion behavior has been reported in several studies with varied efforts in soccer among young trained individuals, untrained individuals, players, and elite players ( Bricout et al, 2010 ; Boullosa et al, 2012 , 2013 ; Bara-Filho et al, 2013 ; Dellal et al, 2015 ; Flatt et al, 2016 , 2017 ; Hammami et al, 2016 ).…”

“…The temporal course of cardiac autonomic recovery reflects the restoration of cardiovascular homeostasis, which is an important component of general recovery ( Stanley et al, 2013 ). Thus, HRV indices may be useful for monitoring the effects of soccer training as they are sensitive to periods of stress and recovery ( Bara-Filho et al, 2013 ). In relation to this, the findings of Boullosa et al (2012) , with male and female Spanish soccer players, suggest that a higher baseline HRV may allow greater use of autonomic resources for responses of soccer players to stress.…”

Purpose: Training methods based on small-sided game (SSG) seem to promote physiological and tactical benefits for soccer players as they present characteristics more specific to the game. Thus, the main objective of the present study was to analyze the hormonal, biochemical, and autonomic parameters in an acute manner and the recovery dynamics (up to 72 h after) in a SSG.Methods: Thirteen professional female soccer players participated in the study (18.8 ± 0.8 years, body mass 59.4 ± 6.2 kg, and height 1.68 ± 0.05 m). During and after the SSG session (4 min × 4 min separated by 3 min of passive interval and 120 m2 coverage per player), autonomic modulation was analyzed in the time and frequency domains using heart rate variability, and blood samples (5 ml) were collected before (0 h) and after (10 min and 24, 48, 72 h) the SSG for biochemical and hormonal analysis.Results: The SSG induced an increase effect for LF (low frequency) (92,52%; Very likely increase) and a decrease effect for HF (high frequency) values (-65,72%; Very likely decrease), after 10 min of recovery. The LF/HF increase after 10 min of recovery (386,21%; Very likely increase). The RMSSD (square root of the mean squared differences of the successive N–N intervals) and pNN50 (measure of the number of adjacent NN intervals which differ by more than 50 ms) values presented a decrease effect 10 min after SSG (61,38%; Very likely decrease and-90%; Very likely decrease). The CK (creatine kinase) values presented no changes 10 min after SSG. The LDH (lactate dehydrogenase) values presented an increase effect 10 min after the SSG (19,22%; Likely increase). Both testosterone and cortisol concentrations presented the same behavior after SSG, where no alterations were observed with after 10 min (<0,37%; Most likely trivial).Conclusion: The SSG promoted significant cardiovascular stress that was restored within the first 24 h of recovery. Parasympathetic parameters continued to increase while sympathetic parameters declined significantly during the 72 h of recovery. In addition, the reduced game did not alter biochemical or hormonal responses during the 72 h.

“…Within the literature, the suggested 10-min ECG period is often divided into a 5-min stability period followed by a 5-min HRV recording period. However, some researchers have used <5 min (Kiviniemi et al, 2007;Plews et al, 2012Plews et al, , 2014Le Meur et al, 2013;Sartor et al, 2013), while others have used >5 min (Leicht et al, 2003;Bara-Filho et al, 2013;Botek et al, 2013b) for stabilization prior to HRV assessment. Therefore, there remains a wide discrepancy within sports science literature as it pertains to the allotted time frames provided for stabilization preceding the criterion segment.…”

Resting heart rate variability (HRV) is a potentially useful marker to consider for monitoring training status in athletes. However, traditional HRV data collection methodology requires a 5-min recording period preceded by a 5-min stabilization period. This lengthy process may limit HRV monitoring in the field due to time constraints and high compliance demands of athletes. Investigation into more practical methodology for HRV data acquisitions is required. The aim of this study was to determine the time course for stabilization of ECG-derived lnRMSSD from traditional HRV recordings. Ten-minute supine ECG measures were obtained in ten male and ten female collegiate cross-country athletes. The first 5 min for each ECG was separately analysed in successive 1-min intervals as follows: minutes 0-1 (lnRMSSD0-1 ), 1-2 (lnRMSSD1-2 ), 2-3 (lnRMSSD2-3 ), 3-4 (lnRMSSD3-4 ) and 4-5 (lnRMSSD4-5 ). Each 1-min lnRMSSD segment was then sequentially compared to lnRMSSD of the 5- to 10-min ECG segment, which was considered the criterion (lnRMSSDC riterion ). There were no significant differences between each 1-min lnRMSSD segment and lnRMSSDC riterion , and the effect sizes were considered trivial (ES ranged from 0·07 to 0·12). In addition, the ICC for each 1-min segment compared to the criterion was near perfect (ICC values ranged from 0·92 to 0·97). The limits of agreement between the prerecording values and lnRMSSDC riterion ranged from ±0·28 to ±0·45 ms. These results lend support to shorter, more convenient ECG recording procedures for lnRMSSD assessment in athletes by reducing the prerecording stabilization period to 1 min.

A medida do impulso de treino (TRIMP) é um método amplamente utilizado para aferir a carga das sessões de treinamento de futebol. Entretanto, poucos estudos investigaram o TRIMP de jogos oficiais desta modalidade. O objetivo do estudo foi analisar e descrever o TRIMP de partidas oficiais de futebol. Dez jogadores (19 ± 1,0 anos; 0,3 ± 7,2 kg, 181,3 ± 6,6 cm; 9,02 ± 1,8% de gordura; 56,4 ± 3,2 mLO2/kg/min-1) da categoria sub 20 participaram do estudo durante três jogos oficiais. A frequência cardíaca máxima (FCmax) foi avaliada em teste de campo. A carga dos jogos foi mensurada através dos valores de TRIMP (TRIMPMOD e TRIMPB) e do percentual do tempo jogado nas cinco zonas de intensidade da FC, sendo desde a zona 1= 65-71% da FCmax a 5= 93-100% da FCmax. O TRIMPMOD e TRIMPB mensurados foram, respectivamente, de 356,34 e 246,27, com diferença significativa entre eles (p<0,05) e baixa correlação (ρ= 0,32). A intensidade de jogo encontrada foi equivalente a 87,76% FCmax. A distribuição do tempo jogado em cada zona de intensidade foi: Z1= 2,46%, Z2= 6,72%, Z3= 20,14%, Z4= 37,03% e Z5= 33,65%. Concluiu-se a diferença entre o TRIMPMOD e TRIMPB deve-se a sua forma de cálculo e que sempre o mesmo deve ser escolhido para monitoramento longitudinal da carga interna de jogos de futebol. Os atletas passaram a maior parte do tempo nas zonas de maior intensidade (Z4 e Z5). No segundo tempo houve um aumento significativo nas zonas 1 e 2 e uma diminuição nas zonas 4 e 5, mostrando uma queda significativa da intensidade entre primeiro e segundo tempo.
