Behaviour of salivary testosterone and cortisol in men during an Ironman Triathlon

2021

Endurance exercise induces notable acute hormonal responses on the gonadal and adrenal hormones. The purpose of this study was to assess the changes in salivary testosterone (Ts), salivary cortisol (Cs) and T/C ratio during long-distance triathlon. Ten well-trained male triathletes participated in the study and were assessed for hormonal changes at four time-points (pre-competition, post-swimming, post-cycling, and post-running phases). Ts decreased from pre-competition to post-swimming (from 93.37 pg/mL to 57.63 pg/mL; p < .01) and increased during two other parts of the competition to almost pre-competition values (cycling: 79.20 pg/mL, p = .02; running: 89,66 pg/mL, p = .04, respectively…

A feasibility study of application and potential effects of a single session transcranial Direct Current Stimulation (tDCS) on competitive anxiety, m…

2020

Objective : To examine feasibility and potential effects of a single session tDCS over the dorsolateral prefrontal cortex (DLPFC) on competitive anxiety, mood state, and autonomic and endocrine stress responses in elite archer athletes under a real world competition. Methods : Twelve male elite archers volunteered to participate in this pilot trial. Participants were randomized in order to take left anodal DLPFC, left cathodal DLPFC, or sham stimulation (the F3 or F4 areas according to the 10/20 EEG International System) in a within-subject study design. This study included three official competitions. About 45 min before the competition, the tDCS stimulation process was started and the par…

Does Music Therapy Improve Anxiety and Depression in Alzheimer's Patients?

2017

OBJECTIVE: To evaluate the effectiveness of the implementation of a short protocol of music therapy as a tool to reduce stress and improve the emotional state in patients with mild Alzheimer's disease. METHODS: A sample of 25 patients with mild Alzheimer's received therapy based on the application of a music therapy session lasting 60 min. Before and after the therapy, patient saliva was collected to quantify the level of salivary cortisol using the Enzyme-Linked ImmunoSorbent Assay (ELISA) immunoassay technique and a questionnaire was completed to measure anxiety and depression (Hospital Anxiety and Depression Scale). RESULTS: The results show that the application of this therapy lowers th…

Recovery of rescuers from a 24-h shift and its association with aerobic fitness.

2017

Objectives: Rescuers work in 24-h shifts and the demanding nature of the occupation requires adequate recovery between work shifts. The purpose of this study has been to find out what kind of changes in autonomic control may be seen during work shift and its recovery period in the case of rescuers. An additional interest has been to see if aerobic fitness is associated with recovery from work shifts. Material and Methods: Fourteen male rescuers (aged 34±9 years old) volunteered to participate in the study. Heart rate variability (HRV) was recorded for 96 h to study stress and recovery, from the beginning of a 24-h work shift to the beginning of the next shift. Aerobic fitness assessment inc…

Dental procedures cause stress in children with cerebral palsy?

2021

Background To evaluate the level of stress during dental care in children and preadolescents with cerebral palsy through biological and psychological parameters. Material and Methods A total of 38 children aged 7 to 12 years were divided into two groups: one with 18 children with cerebral palsy and the other with 20 healthy children (control group). Saliva was noninvasively collected before and after dental care to analyze salivary biomarkers. The Frankl Behavior Scale and the Facial Image Scale were applied. Results After the dental procedure, cortisol levels were significantly higher (p = 0.02) in the cerebral palsy group than in the control group. Salivary alpha-amylase was not significa…

Cognitive emotion regulation withstands the stress test: An fMRI study on the effect of acute stress on distraction and reappraisal

2021

Cognitive emotion regulation is a key mechanism for the maintenance of mental health, but may fail, when individuals are exposed to acute stress. To date, it is not well understood whether and to what extent acute stress effects contribute to impairments in emotion regulation capacities as the sparse existing studies have yielded heterogeneous results, indicating that stress timing might be a crucial factor.In the present study, 81 healthy participants underwent either an acute stress task (ScanSTRESS-C; n = 40) or a control condition (n = 41) while lying in the MRI scanner. In the subsequent Cognitive Emotion Regulation Task (CERT), participants were confronted with neutral or negative pic…

Salivary Testosterone and Cortisol Responses to Cycle Ergometry in Basketball Players with Different Training Volume

2002

Abstract This study analyzes the degree to which different amounts of training during a 4-month period affects salivary testosterone (Tsal), salivary cortisol (Csal) responses, and changes in the salivary testosterone/cortisol ratio (Tsal/Csal ratio) following acute physical effort. Two professional basketball teams with similar fitness levels carried out a maximal cycle ergometry at the beginning and in the middle of the sports season. In both sessions, saliva samples were collected to determine Tsal and Csal, and mood was assessed. Training was registered daily, total training volume being almost two-fold higher in Team 1 than in Team 2. No significant differences between the teams in an…

Use of Saliva in Alternative to Serum Sampling to Monitor Biomarkers Modifications in Professional Soccer Players

2018

We aimed to investigate the correlation between serum and salivary concentrations of steroid hormones and IgA, and the variation in concentrations of these biomarkers, across a soccer competitive season in a sample of players playing for an Italian major League team. Thirty-five elite male soccer players were recruited and assessed for salivary hormones (cortisol, testosterone, T/C‰ and DHEA-S) and IgA at three different time-points: (t1) after the pre-season period and 16 official matches played; (t2) after a winter break and three official matches played; (t3) 2 days after the final match of the championship and 19 matches played. Players were also tested for blood biomarkers (ser-C, ser-…

Salivary characteristics may be associated with burning mouth syndrome?

2020

Background Burning mouth syndrome (BMS) it is characterized by burning and uncomfortable sensations with no clinical alterations or laboratory findings. The evaluation of the salivary characteristics of people with BMS can help the understanding of the pathogenesis of this condition. This case-control study aimed to trace the salivary profile of women with burning mouth syndrome (BMS). Material and Methods 40 women with BMS and 40 control women were recruited. Unstimulated salivary flow rate (uSFR), pH, salivary cortisol levels, salivary viscosity, and oral health impact profile (OHIP-14 questioner) were determined. P< 0.05 was considered statistically significant. Results For uSFR, mean va…
