“…Immediately after collection, each saliva sample was assessed for sIgA and sAA concentrations using an IPRO lateral flow device (IPRO Interactive, Oxfordshire, UK) point of care system as previously described [ 27 ]. This method of saliva analysis has previously been validated against ELISA analysis (R 2 = 0.78) [ 28 ].…”

Effect of Chronic Training on Heart Rate Variability, Salivary IgA and Salivary Alpha-Amylase in Elite Swimmers with a Disability

et al. 2015

The purpose of this study was to a) determine the heart rate variability (HRV) and saliva markers of immunity (salivary immunoglobulin A; sIgA) and stress (salivary alpha-amylase; sAA) responses to chronic training in elite swimmers with a disability; and b) identify the relationships between HRV, sIgA, sAA and training volume. Eight members of a high performance Paralympic swimming program were monitored for their weekly resting HRV, sIgA and sAA levels in the 14 weeks leading up to a major international competition. The 14 week training program included aerobic, anaerobic, power and speed, and taper training phases, while also incorporating two swimming step tests and two swimming competitions. Specific time (root mean square of the successive differences; RMSSD) and frequency (high frequency normalized units [HFnu]) domain measures, along with non-linear indices (standard deviation of instantaneous RR variability; SD1 and short term fractal scaling exponent; α1) of HRV were used for all analyses with effects examined using magnitude-based inferences. Relationships between HRV and saliva markers were identified by Spearman rank rho (ρ) correlation coefficients. Compared with week 1, SD1 was very likely lower (96/4/0, ES = -2.21), while sAA was very likely elevated (100/0/0, ES = 2.32) at the beginning of week 7 for all athletes. The training program did not alter HRV or saliva whereas competition did. There were also no apparent differences observed for HRV, sIgA and sAA between each of the training phases during the 14 week swimming program. Correlations were observed between sAA and SD1 (ρ = -0.212, p<0.05), along with sAA and mean HR (ρ = 0.309, p<0.05). These results show that high level national competition influences depresses HRV (SD1) and increases saliva biomarkers of stress (sAA). It appears that a well-managed and periodised swimming program can maintain these indices within normal baseline levels. The study also highlighted the parasympathetic nervous system influence on sAA.

“…Biological fatigue markers are often used alongside ASRM to provide objective understanding of the workload-recovery relationship (12,13,15). Of these, salivary biomarkers are particularly popular (12) because samples can be easily obtained noninvasively (16) and results for entire squads (~25 players) can be available in ~30 min using point-of-care analysis systems (4)(5)(6)12,(17)(18)(19).…”

This investigation examined the longitudinal changes and inter-relationships of salivary and self-report monitoring measures across a professional football season. MethodsMeasures were collected bi-weekly from 18 senior professional male players across a six-week pre-season and eight five-week in-season mesocycles and analysed using a linear mixed-effects model. ResultsAnalysis identified a small (P=0.003) cross-season suppression of salivary immunoglobulin-A, small reductions to salivary 𝛼-amylase (P=0.047) and salivary cortisol (P=0.007), and trivial changes to salivary testosterone (P>0.05). The testosterone:cortisol ratio typically responded inversely to changes in player workload. Self-report measures of fatigue (P=0.030), sleep quality (P=0.003) and muscle soreness (P=0.005) improved (ES=small) across the first half of the season. Fatigue and sleep measures were most consistently related to hormonal measures (R 2 = 0.43 to 0.45). For these relationships, increases in cortisol were associated with compromised self-report responses, whereas increases in testosterone:cortisol were associated with improved responses. Non-linear relationships were identified for fatigue with immunoglobulin-A (P=0.017; ES=trivial) and testosterone (P=0.012; ES=trivial); for sleep quality with testosterone (P<0.001; ES=trivial); for muscle soreness with testosterone (P=0.012; ES=trivial) and for the self-report inventory sum with testosterone (P=0.027; ES=trivial). For these relationships, self-report responses were optimal at mean immunoglobulin-A and testosterone levels and very low levels (-2 SD) exerted the most compromising effects. ConclusionPlayers can experience a chronic cross-season suppression of mucosal immunity. Salivary immunoglobulin-A, testosterone, cortisol and testosterone:cortisol measures relate to selfreport measures of fatigue, sleep quality and muscle soreness. In-season reductions in testosterone, cortisol and testosterone:cortisol or increases in cortisol among elite football players could be used to indicate the need for reduced workload, which might lead to improved wellbeing.

Exploring role of sleep aids in sleep problems in preschool children

It is well known that children use sleep aids, such as blankets or soft toys, at bedtime. However, there is a lack of understanding regarding the factors associated with their use and role in addressing sleep problems. This study investigated 96 Japanese children aged 40 to 47 months to examine these associations. We measured children’s stress (through a questionnaire and salivary cortisol [cortisol awakening response]), anxiety symptoms, behavioral problems, and temperament, and created a model to predict the status of sleep aid use. Furthermore, we explored the association between sleep aid use and children’s sleep problems as evaluated by their caregivers. We found that children who used sleep aids were more likely to experience anxiety symptoms. Moreover, most children used sleep aids even when they co-slept with their caregivers and/or siblings. Their use was not uniquely associated with sleep problems. These findings suggest that sleep aid serves as a defense against anxiety, including that caused by the absence of a caregiver, rather than as a substitute for a caregiver. Our study sheds light on their role and emphasizes the importance of viewing development within the complex interactive processes of humans and objects.
