“…The Omegawave diagnostic system is a new system that is designed to evaluate the state of physical function; it can measure VO2max and other indicators in elderly individuals. Research shows that the Omegawave diagnostic system has a high correlation with the results of traditional laboratory tests of function [ 18 ]. Traditional laboratory testing requires the elderly to do their best, and an Omegawave diagnostic system may be more suitable than other systems for testing the elderly.…”

Objective To verify the reliability and validity of the simplified Chinese version of the Yale Physical Activity Survey (YPAS) scale in the measurement of physical activity of elderly women in mainland China to provide a new standardized scale for evaluating the level of physical activity. Methods Twenty-one healthy elderly women completed all the research procedures. The participants completed the questions on the YPAS and wore an Omegawave Sport Technology®System diagnostic system that recorded maximum oxygen uptake and the adaptation index of the energy metabolism system. The reliability of the YPAS was evaluated based on the consistency of the two measurements (pre-test and post-test), and its validity was verified based on the relevant indicators in the Omegawave diagnostic system. Descriptive statistics, intraclass correlation coefficient and Pearson correlation analysis were used. The significance level was set at p < 0.05. Results In terms of reliability, the Pearson correlation coefficient and ICC of the total physical activity time of YPAS (r = 0.917, ICC = 0.897) was high. In terms of total calories, the Pearson correlation coefficient and ICC of the two test results was high (r = 0.958, ICC = 0.934). On the YPAS total index, the Pearson correlation coefficient and ICC of the two test was high (r = 0.930, ICC = 0.920). In terms of validity, there was a moderate correlation between the energy metabolism system adaptation index and the YPAS-total time (r = 0.472) and a moderate correlation with total calories (r = 0.472). There was a high correlation between the YPAS-total index and the maximum oxygen uptake (r = 0.782). Conclusion The simplified Chinese version of the YPAS can measure the level of physical activity and energy metabolism of elderly women in mainland China. It is a reliable tool for measuring the physical activity of the elderly.

“…Raw values were exported and analyzed. This technology has been shown to have acceptable sensitivity to training activity (e.g., hard, easy, rest days) (6) and acceptable agreement reported with an ambulatory electrocardiogram system (coefficient of variation = Omegawave 0.08; electrocardiogram 0.09) (18). An Omegawave ECG1A device was positioned at the upper thorax, with each individual HRV measurement completed while resting comfortably and motionless in a supine, with arms by the subjects' side in a quiet room.…”

Grainger, A, Heffernan, S, Waldron, M, and Sawczuk, T. Autonomic nervous system indices of player readiness during elite-level rugby union game-week microcycles. J Strength Cond Res 36(11): 3173–3178, 2022—Elite-level rugby union (RU) is a high-intensity contact sport that involves large training and match volumes across a season, which can lead to postmatch fatigue. Autonomic nervous system (ANS) regulation and perceived fatigue have been suggested to relate to measures of training and match load in RU. However, there have been no studies to assess specific ANS variables in elite RU during in-season microcycles. Player readiness during game-week microcycles was measured via heart rate variability (HRV) indices, direct current potential and self-reported well-being among 13, elite, male RU players. To enable comparison, data collection days were categorized in relation to their proximity to match day, ranging from match day minus 3 (MD − 3), to match day plus 3 (MD + 3). Differences between match days were evaluated using general linear models and Cohen's d effect sizes. There were significant differences between MD and MD + 1 for ANS indices (RMSSD p = 0.04, d = −0.66, 95% CI 0.11–1.20; the standard deviation of NN intervals p = 0.04, d = −0.66, 95% CI 0.12–1.20; total power p = 0.05, d = −0.65, 95% CI 0.11–1.20) and wellness measures (readiness p = 0.18; d = −2.33, 95% CI, 1.54–3.13; energy p = 0.02; d = −2.24, 95% CI 1.44–3.03; soreness p = 0.00; d = −2.42, 95% CI 1.63–3.23). Match day plus 3 effects were significantly greater than MD + 1 in several ANS responses, with wellness recovering at a slower time-course than ANS responses. Measures of HRV are dysregulated postmatch, but based on their rapid recovery thereafter, using HRV to assess readiness of elite-level players in RU across a weekly microcycle could be limited and requires further investigation.

“…There is not much information on the DC potential and sports, primarily due to the fact that most studies were carried out in the Soviet Union and they have not yet been translated, and, secondly, because there is no standard terminology; therefore, researchers have given different names to the term ‘DC potential’, for example, slow cortical potential [ 15 ], steady potential [ 16 ], or infra-slow cortical potential [ 17 ]. Omegawave ® is a tool that is currently used not only in the medical area [ 18 , 19 ], but also in sports in which it has been validated [ 20 ], where coaches and sport scientists use it to understand how athletes’ bodies work and to improve their fitness in the different stages of the training process, using variables related to brain activation and heart variability, providing information about the level of sympathetic and parasympathetic activation of athletes [ 21 , 22 ].…”

The aim of this work was to relate the activation of the sympathetic and parasympathetic nervous systems with the skin temperature (Tsk) of the lower limbs after a resistance training exercise. Under controlled conditions, the average Tsk in the areas of the anterior and posterior thighs, knees and legs was obtained with a thermal imager and the parasympathetic and sympathetic activation was registered with an Omegawave® device on 20 healthy and trained male volunteers (25.39 ± 8.21 years) before exercise, immediately after standard resistance training (3 exercises (2 quadriceps + 1 hamstrings) × 4 sets × 10 repetitions (70% 1RM), 90-sec recovery) and after 20 min of recovery. The results showed a significant effect of exercise and recovery on Tsk in all regions of interest (ROIs) considered (p < 0.05) and strong inverse relationships between sympathetic and parasympathetic activation values. Significant results were found for the total variation of Tsk (p < 0.05) with highly positive values for subjects with lower sympathetic activation and almost null or even negative values for those with higher sympathetic activation. Sympathetic activity was a significant predictor of total Tsk variation in the anterior thigh, posterior thigh and anterior knee but not in the posterior knee, anterior leg, and posterior leg. Baseline Tsk was a significant predictor of total Tsk variation the all ROIs except in the posterior knee. Tsk measured by thermography could be used to estimate the level of participation of muscle areas in exercise and registering the level of sympathetic activation before exercise could be interesting in predicting the athlete’s physiological response to strength training.
