“…As described earlier, the increased training load and stress were highlighted by increased sympathetic activation and parasympathetic withdrawal 20,21,25 , which might be accounted for reduced salivary flow rate and lower levels of Cl and K in saliva during the intense training period. Other authors described low levels of salivary K found in young female fencers and field hockey athletes in relation to control subjects 4 . The authors correlated the low level of salivary K to increased loss of the element due to training since athletes presented increased concentrations of K in hair samples 4 .…”

“…Athletes at rest and under high physical efforts differently modulate the circulating, urinary, and salivary concentrations of several chemical elements [1][2][3][4][5] . This fluctuation in body fluid chemical content may be related to physical and metabolic demands (aerobic x anaerobic adaptations), oxidative stress, inflammatory status, nutritional strategies, and muscle damage 1,2,6,7 .…”

The saliva analysis by Total Reflection X-Ray Fluorescence (TXRF) for monitoring training loads could be useful due to the ease of sample analysis and a large range of chemical elements can be detected. Twelve BJJ athletes were submitted to 7 weeks of training scheduled with high training loads (weeks 1 to 4) and tapering (weeks 5 to 7). Saliva samples were collected before (Pre), at week 4, and at week 8 (Post), to quantify chemical element concentrations by TXRF. The internal training load was monitored using the session rating of perceived exertion of session (RPE) method for physical and technical-tactical training sessions. All the saliva samples presented Phosphorus (P), Sulfur (S), Chlorine (Cl), Potassium (K), Calcium (Ca), Zinc (Zn), Bromine (Br), and Rubidium (Rb) at Pre, 4 weeks and Post time points. Salivary concentrations of Cl, K, Manganese (Mn), Copper (Cu), Br, and Rb significantly decreased in 4 weeks (p<0.05); and K, Cu, and Rb concentration remained at low levels at Post (p<0.05). Medium to large Cohen´s effect sizes for decrements in element concentrations from Pre to 4 weeks was observed for all the elements except Zn. Reduced S concentration at 4 weeks was negatively correlated to high training load period (r=-0.56, p=0.05). The results suggest that BJJ training modulates salivary electrolyte composition and salivary P, S and Rb are correlated with training loads in BJJ athletes.Keywords: Ions. Martial Arts. Exercise.

Doze atletas de BJJ foram submetidos a 7 semanas de treinamento programado com altas cargas de treinamento (semanas 1 a 4) e polimento (semanas 5 a 7). Amostras de saliva foram coletadas antes (Pré), na semana 4 (Meio) e na semana 8 (Pós), para quantificar as concentrações dos elementos químicos por TXRF. A carga interna de treinamento foi monitorada por meio do método de percepção subjetiva de esforço da sessão (PSE) nas sessões de treinamento físico e técnico-tático. Todas as amostras de saliva apresentaram Fósforo (P), Enxofre (S), Cloro (Cl), Potássio (K), Cálcio (Ca), Zinco (Zn), Bromo (Br) e Rubídio (Rb) no momento Pré, 4 semanas e Pós. As concentrações salivares de Cl, K, Manganês (Mn), Cobre (Cu), Br e Rb diminuíram significativamente em 4 semanas (p <0,05); e a concentração de K, Cu e Rb permaneceram em níveis baixos no Pós (p <0,05). Os tamanhos de efeito de Cohen médio a grande para decréscimos nas concentrações de elementos, de Pré a 4 semanas, foram observados para todos os elementos, exceto para Zn. A redução da concentração de S em 4 semanas foi negativamente correlacionada com o período de alta carga de treinamento (r = -0,56, p = 0,05). Os resultados sugerem que o treinamento de BJJ modula a composição eletrolítica salivar e o P, S e Rb salivares estão correlacionados com as cargas de treinamento no BJJ.Palavras-chave: Íons.

“…Дисэлементозы у юных спортсменов -наименее изученные, хотя и чрезвычайно распространенные состояния. Они интенсивно изучаются на протяжении нескольких лет специалистами различных направлений в России [18] и за рубежом, но интерес к данной проблеме не ослабевает. Среди элементов, которые входят в состав человеческого тела, кальций занимает пятое место после четырех главных элементов -углерода, кислорода, водорода и азота.…”

“…Physical exercise may also lead to changes in the content of trace elements and electrolytes in resting mixed saliva ( Chicharro et al, 1999 ; Nabatov et al, 2017 ). The stimulation of the sympathetic system may result in changes in the salivary flow, reabsorption and the secretion of electrolytes in the secretory cells by modifying the ion concentration of the saliva.…”

Exercise may induce many changes in biochemical parameters of the saliva. Thanks to non-invasive access, saliva can be used as a diagnostic material in physical activity monitoring. The aim of the study was comparison of selected salivary components in swimmers before and after training session. 40 male subjects aged 12–15, out of whom 30 were competitive swimmers and 10 control were involved in the study. Salivary samples were collected from all subjects in the morning, and in the afternoon; from the swimmers, they were also collected before and after the workout. Salivary flow rate-V, pH, total protein-P, alpha-amylase-Amy, salivary peroxidase-SPO, cortisol-C, total antioxidant status-TAS, sialic acid (free-FSA, bound-GSA, total-TSA), calcium-Ca, magnesium-Mg were measured. The swimmers assessed the workout intensity of training session using the RPE Foster’s scale. The circadian rhythm pattern of some salivary components and differences after training were found. In swimmers after the morning exercise significant increase of P (0.83 ± 0.27 vs. 1.10 ± 0.58 g/L), Amy (64.91 ± 70.86 vs. 87.07 ± 92.46IU/L), Ca (3.83 ± 1.33 vs. 4.99 ± 2.24 mg/L), Mg (0.52 ± 0.32 vs. 0.73 ± 0.34 mg/L), TAS (0.64 ± 0.27 vs. 0.72 ± 0.26 mmol/L) and decrease V (0.47 ± 0.37 vs. 0.36 ± 0.22 mg/min), C (5.86 ± 5.00 vs. 3.54 ± 5.07 μg/ml) were found. After the afternoon training significant increase of pH (7.13 ± 0.33 vs. 7.27 ± 0.24), Amy (111.53 ± 120.13 vs. 130.91 ± 161.14IU/L), Ca (3.72 ± 1.34 vs. 4.61 ± 1.58 mg/L), Mg (0.48 ± 0.28 vs. 0.60 ± 0.39 mg/L), TSA (5.64 ± 3.78 vs. 6.10 ± 3.08 mg/L), GSA (3.00 ± 3.06 vs. 3.38 ± 2.26 mg/L), and decrease of V (0.63 ± 0.63 vs. 0.49 ± 0.39 ml/min) were noticed. Before training in the morning in the swimmers significantly higher of V (0.47 ± 0.37 vs. 0.26 ± 0.15 mg/min), TAS (0.64 ± 0.27 vs. 0.40 ± 0.16 mmol/L), and lower pH (7.01 ± 0.46 vs. 7.53 ± 0.33), P (0.83 ± 0.27 vs. 1.86 ± 1.28 g/L), Amy (64.91 ± 70.86 vs. 146.56 ± 114.45IU/L) compared to the control were found. In the afternoon in swimmers before training session significantly lower pH (7.13 ± 0.33 vs. 7.53 ± 0.49) and Amy (111.53 ± 120.13 vs. 170.98 ± 107.72IU/L) in comparison to the control were noticed. The RPE scores were negatively correlated with V (rho = −0.500, p = 0.05 and pH (rho = −0.382, p = 0.03) measured after the morning session and after the afternoon training with V (rho = −0.570, p = 0.01) and Ca (rho = −0.401, p = 0.08). The levels of salivary flow rate, alpha amylase, cortisol, calcium, magnesium were associated with swimming training session, and showed circadian variation without a significant effect on their responses to exercise.
