“…Although previous findings have shown that females have slower reaction time compared to males (Bleecker, Bola-Wilson, Agnew, & Meyers, 1987;Dane & Erzurumluoglu, 2003;Der & Deary, 2006) a trend of equation of reaction time between females and males has been reported by Silverman (2006). The results of our study have shown that tested female cadet handball players have an overall SVRT mean of 190.07±2.92 ms which is a slightly shorter RT compared to female ACPS (Academy of Criminalistic and Police Studies) students tested with the same methodology who had a mean SVRT of 202.30±18.89 ms (Marković, Vučković, & Janković, 2019). The presented results of the overall sample as well as the results of the respective subsamples of cadet and junior players that have a SVRT mean value of 194.28±3.80 and 184.73±4.31 ms can be directly compared with the results of moderately and highly active females who have mean SVRT values of 203.07±19.47 and 191.68±16.57 ms, respectively (Marković & Dopsaj, 2018).…”

“…In the lack of similar data the presented results can be compared with the results calculated from the data obtained with the same methodology that was used in previous publications. When compared with female ACPS students, an RTV of 9.78±4.78 % and active females that have an RTV at the level of 10.46±7.23 % (Marković & Dopsaj, 2018;Marković et al, 2019) the RTV values found in the samples considered in this research indicate higher levels of acute concentration in trained participants. An explanation for shorter reaction time in physically active participants was proposed by Spirduso (1975) who points out to the possible positive relationship between augmented excitation and continuous demands for fast decision making during sports activities and enhanced neural efficiency, which can possibly also contribute to higher levels of acute concentration, i.e.…”

This paper aims to define differences in Simple Visual Reaction Time (SVRT) and Reaction Time Variation (RTV), related to age and player position in Serbian female cadet and junior national handball team members. The method used in this research was laboratory testing. All data sampling was performed using specially designed testing software that recorded visual reaction time with 1 ms precision. SVRT was expressed in ms, and RTV was expressed as a coefficient of variation percentage value. The overall sample consisted of 34 players - 19 cadets and 15 juniors. Mean SVRT of 194.28±16.55 and 184.73±16.68 ms was determined in the subsamples of cadet and junior players, respectively. It was found that cadets have a mean RTV of 4.74±2.41% while juniors have a mean RTV of 7.90±3.70%. Results of the Factorial ANOVA have shown that there are no general, statistically significant, differences in SVRT in relation to age, player position, and interaction of these factors (p>0.05). Statistically significant difference in RTV on a general level was found in relation to age (F=9.752, p=0.005), while differences in relation to player position or combination of these factors were not statistically significant (p>0.05). Post hoc tests have shown partial differences in relation to player position. The method of mathematical modelling was used to define the statistical model of performance in relation to the given variables. The final form of the model explained 100% of the measured variance (AdjR2 = 1.000), which implies its absolute predictive potential considering the characteristics of the sample.

“…If the normal distribution was not given, nonparametric tests were employed. Reaction times were resolved by excluding misses and values below 150 ms as well as all reaction times above 414 ms (75. quartile plus 3*IQR) as outliers ( Baayen and Milin, 2010 ; Marković et al, 2019 ).…”

Healthy aging is accompanied by multi-faceted changes. Especially within the brain, healthy aging exerts substantial impetus on core parts of cognitive and motivational networks. Rewards comprise basic needs, such as food, sleep, and social contact. Thus, a functionally intact reward system remains indispensable for elderly people to cope with everyday life and adapt to their changing environment. Research shows that reward system function is better preserved in the elderly than most cognitive functions. To investigate the compensatory mechanisms providing reward system stability in aging, we employed a well-established reward paradigm (Monetary Incentive Delay Task) in groups of young and old participants while undergoing EEG measurement. As a new approach, we applied EEG connectivity analyses to assess cortical reward-related network connectivity. At the behavioral level, our results confirm that the function of the reward system is preserved in old age. The mechanisms identified for maintaining reward system function in old age do not fit into previously described models of cognitive aging. Overall, older adults exhibit lower reward-related connectivity modulation, higher reliance on posterior and right-lateralized brain areas than younger adults, and connectivity modulation in the opposite direction than younger adults, with usually greater connectivity during non-reward compared to reward conditions. We believe that the reward system has unique compensatory mechanisms distinct from other cognitive functions, probably due to its etymologically very early origin. In summary, this study provides important new insights into cortical reward network connectivity in healthy aging.
