The effects of different music types on tennis performance among recreational players.

It is known that different types of music used during sports performance has different psycho-physiological effects. In this context, this study aimed to reveal the effect of different types of music on ITN test performance in tennis players. A total of 35 recreational tennis players voluntarily participated in the study. In the research, the ITN test performance of tennis players was measured in three different conditions with 48-hour intervals, these being without music, with motivational music, and with sedative music. The Freidman test was used in the analysis of the data that did not show a normal distribution, and the Repeated Measures ANOVA test was used in the analysis of the data that showed a normal distribution. According to the main findings of the study, it was determined that motivational music increased the ITN test performance of tennis players, while sedative music decreased their ITN test performance (p< .05). Additionally, it was determined that motivational music increased the groundstroke depth scores of tennis players, while sedative music decreased groundstroke depth scores (p< .05). In addition to this, it was determined that volley depth, groundstroke accuracy, and serve scores increased through motivational music (p< .05), whereas sedative music had no effect (p> .05). As a result, it was determined that the ITN test performances of tennis players can be increased through the psycho-physiological effect of motivational music. It can therefore be concluded that the use of motivational music during training and matches (between sets and/or time breaks) of tennis players can increase their shooting performance.

Turkish version of a short nutrition literacy scale for young adults: cultural adaptation and validation.

Background: Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent. Purpose: The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023). Methods: This research involved 115 young adults from Istanbul Gelisim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups. Results: As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ2/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults. Conclusion: The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.

Nature relatedness, flow experience, and environmental behaviors in nature-based leisure activities.

Introduction: Through nature-based leisure activities, spending time in nature offers opportunities to reduce stress, relax the mind, and enhance feelings of well-being. Being aware of the benefits provided by these activities increases the nature relatedness, and during the time spent in nature, it enables experiencing positive and satisfying moments by entering into a state of flow. The concepts of nature-relatedness and flow experience represent psychological experiences and characteristics that play an important role in enhancing psychological well-being and life quality. Methods: Based on structural equation models, the relationships among nature-relatedness, flow experience, and environmental behaviors were investigated. Data were collected from 379 individuals (212 male, 167 female) who regularly engage in nature-based leisure activities such as cycling, hiking, and fishing. The participants were predominantly male (55.9%) and aged 45 years and over (53.3%). Results: The nature-relatedness significantly influences flow experience (R 2 = 0.505, p < 0.01), environmental behavior (R 2 = 0.108, p < 0.01), environmental sensitivity (R 2 = 0.137, p < 0.01), and communication with nature (R 2 = 0.200, p < 0.01). Specifically, nature-relatedness directly enhanced environmental sensitivity (0.494 total effect), environmental behavior (0.604 total effect), and communication with nature (0.599 total effect) and did so both directly and indirectly through the mediation of flow experience. Discussion: A higher level of nature-relatedness can lead to a stronger flow experience, which in turn can increase positive. environmental behavior, environmental sensitivity, and communication with nature.

Effects of 8-week alkaline diet and aerobic exercise on body composition, aerobic performance, and lipid profiles in sedentary women.

Background: Diet composition can affect systemic pH and acid-base regulation, which may in turn influence exercise performance. Purpose: It was aimed to determine the effects of the alkaline diet and 8 weeks of aerobic exercises on body composition, aerobic performance, and blood lipid profiles in sedentary women. Methods: Thirty-two sedentary women participated in the study voluntarily. The research was designed with a true-experimental design and the participants were divided into four different groups as the control group, aerobic exercise group, alkaline diet group, and alkaline diet + aerobic exercise group. The body compositions, aerobic exercise performances, and lipid profiles of sedentary women were measured as pre-test and post-test. In the analysis of the obtained data, One-Way ANOVA with Bonferroni post hoc test was used. Results: It was observed that the alkaline diet consumed with 8 weeks of aerobic exercises caused a 5.17% decrease in BMI and an increase of 42.07 and 37.62% in VO2max and aerobic test durations, respectively (p < 0.05). In addition, when lipid profiles were examined, it was determined that there was no statistically significant difference in HDL-C levels (p > 0.05). Despite that, there were statistically significant differences in TG and LDL-C levels (p < 0.05). According to this result, it was determined that there was a decrease in TG and LDL-C levels by 37.61 and 20.24%, respectively. Conclusion: An alkaline diet consumed with 8 weeks of aerobic exercises in sedentary women has positive effects on improving body composition, aerobic exercise performances, and TG and LDL-C levels.
