“…During this period, the risk of mortality by coronary heart disease has been found to be two to 10 times higher for firefighters engaged in firefighting activities in comparison with other on‐duty activities . Different methods have been proposed to improve parasympathetic reactivation after high‐intensity exercise, such as cold‐water immersion or water intake . Future research studies using real interventions are required to confirm the results of the present study.…”

This study aimed to assess the effect of wearing a breathing apparatus during a simulated rescue intervention on psychophysiological responses and parasympathetic reactivation of firefighters. Thirty-four firefighters participated in this study which consisted of four experimental sessions conducted randomly: a maximal fitness test and three rescue interventions performed (a) with personal protective clothing (PPC); (b) with PPC and the full self-contained breathing apparatus (SCBA), including cylinder, full-face piece, and breathing regulator; and (c) with PPC and only the cylinder of the self-contained breathing apparatus (SCBAc). Physiological (heart rate [HR], breathing frequency [BF]) and perceptual (rating of perceived exertion [RPE]) responses were continuously collected during the three rescue interventions. Parasympathetic reactivation was assessed using HR recovery and variability indexes after experimental sessions. HR responses ranged between 63% and 95% of HR , and BF responses ranged between 22 and 55 breaths/min for the different activity tasks. Parasympathetic reactivation indexes were similar for the rescue interventions but lower than after the intermittent fitness test (P = 0.016 - P < 0.0001). Mean HR for both SCBAc (83.2 ± 4.1%HR ) and SCBA (83.1 ± 5.2%HR ) was higher in comparison with PPC (79.5 ± 5.3%HR ). RPE was higher for SCBA than for SCBAc which was higher than PPC. Mean BF for SCBA (34 breaths/min) was lower than PPC (40 breaths/min) and SCBAc (43 breaths/min). Based on HR, BF, and RPE, rescue interventions seem to be psychologically and physiologically stressful. Parasympathetic reactivation after PCC, SCBA, and SCBAc suggests that these conditions induce higher cardiac stress than the maximal fitness test. The study showed that SCBA increased psychophysiological perturbations.

“…It has been proven repeatedly that water intake accelerates parasympathetic activation. 37,38 HF specifically reflects parasympathetic nervous system activity, which was found to increase significantly post-WDT in this study. There was also significant correlation between SCAR and HF; HF increased and HR decreased concurrently at 15-minutes post-WDT, and there was a negative correlation between HF and HR (r ¼ À0.6115; P ¼ 0.0002), which indicated that activation of parasympathetic nerves might be involved in the collapse of SC during the WDT.…”

“…However, Peçanha et al 37 and Kawano et al 38 found a positive effect of water consumption on vagal activity after moderate-to-high intensity exercise. These authors have suggested that a vagal activity increase post-WDT occurs to counterbalance a potential sympathetic pressor effect evoked by exercise.…”

“…Vagal dysfunction appears to be associated with the onset of cardiovascular disease 2 in addition to being an important predictor for sudden death [2][3][4][5] . Thus, several research groups have dedicated themselves to investigating the effects of different variables on CVA, among which water intake is prominent [6][7][8] .…”

RESUMOO objetivo foi analisar o efeito da ingestão de duas quantidades de água na modulação autonômica. Participaram 26 homens, com idade entre 18 e 30 anos, foram submetidos a dois dias de intervenção e avaliação com intervalo de 24 horas. O protocolo consistiu na ingestão de 250 ou 500 mL de água, em ordem randômica. Para avaliar o TIFC no exercício dinâmico foi utilizado o índice vagal cardíaco (IVC) obtido por meio do Teste de Exercício de 4 segundos nos momentos pré e pósingestão (5º, 10º, 20º e 30º minutos). Para avaliar a modulação autonômica no repouso foi utilizada a VFC durante 30 minutos após a ingestão, quando foi registrado a FC de repouso. Os resultados apontam que após 5 minutos da ingestão de água houve um aumento do TIFC (p=0,02), sem que houvesse diferença em função dos volumes de água ingeridos (p=0,8). Na VFC não houve diferença entre os volumes ingeridos, tanto no domínio do tempo quanto no domínio da frequência. Em relação a FC de repouso, houve diferença no 20º minuto quando comparado aos demais momentos (p<0,05). Conclui-se que os nossos resultados demostraram que não houve diferença no TIFC, VFC e na FC de repouso quando foram comparadas a ingestão de 250 e 500 mL de água à temperatura ambiente em indivíduos saudáveis. Contudo, o TIFC e a FC de repouso demostraram diferença entre os momentos analisados. Palavras-chave: Hidratação. Frequência cardíaca. Sistema nervoso autonômico. ABSTRACTThe purpose was to analyze the effect of the ingestion of two amounts of water in the autonomic modulation. A total of 26 men aged 18-30 years under went 2 days of intervention and evaluation with 24 hours in between. The protocol consisted of the intake of 250 or 500 mL of water in a random order. To assess the initial transient HR during dynamic exercise, the cardiac vagal index was obtained using a 4-second exercise test during the pre-and post-ingestion periods (5, 10, 20, and 30 minutes). To evaluate autonomic modulation at home, HRV value 30 minutes after water intake was used when HR at rest was registered. The results shows: Five minutes after the water intake, the initial transient HR was increased (p = 0.02) with no difference in effect of the ingested volumes of water (p = 0.8). In HRV, there was no difference between the intake volumes in the time or frequency domains. There were differences in HR rest after 20 minutes compared to at other times (p < 0.05). In conclusion the results showed no difference in initial transient HR, HRV, or HR rest after the intake of 250 versus 500 mL of room temperature water in healthy individuals. However, resting initial transient HR and HR rest values differed among the analyzed times.

Water Intake Accelerates Parasympathetic Reactivation After High-Intensity Exercise

Abstract: The results suggest that WI accelerates the postexercise parasympathetic reactivation after high-intensity exercise. Such outcome reveals an important cardioprotective effect of WI.
