Background: Limited research has investigated the use of chamomile as an antioxidant supplement in team sports . Purpose : The aim of this study was to investigate the effect of chamomile extract on antioxidant indices in young female futsal players. Methods : 20 young female futsal players (Average age: 22.08 ± 5.03 years, weight: 54.4 ± 8.62 kg, and body mass index: 20.56 ± 2.6 kg/m2) were divided randomly into two groups, experimental group (10 people) and control group (10 people). The experimental group consumed 1500 mg/day of the supplement for one week, while the control group received a placebo. Both groups were nutritionally controlled during this period. After the end of the intervention period, two simultaneous futsal matches were held for two groups (two teams of 5 players in each match). Anthropometric characteristics were evaluated in resting conditions and biochemical markers were measured before the intervention, immediately after the competition, and 30 minutes after the competition. Data analysis was performed using the repeated measurement variance test. The level of significance was considered at P<0.05. Results : The results showed a significant increase in SOD levels (P<0.05) and a significant decrease in CAT levels (P<0.05) immediately after the competition in the supplement group, but this significance was not seen 30 minutes after the competition. Conclusion : One-week consumption of chamomile improves antioxidant defense in young female futsal players. Conducting studies with long-term follow-up to confirm these findings should be considered.

Background: Losing a limb can negatively impact balance and gait, leading to reduced quality of life.Aim: This study aimed to examine correlations between spatiotemporal gait and balance with scores of the Quality of Life questionnaire.Materials and Methods: 30 veterans with unilateral below-knee amputations underwent gait analysis to measure step length, stride length, stance time, cadence, velocity, and walking symmetry index by step length. Static balance was assessed via the center of pressure path length by Wii Balance Board during standing. The Timed Up and Go test evaluated dynamic balance. The QoL scores were recorded using the Quality of Life questionnaire for amputees, Trinity Amputation, and Prosthesis Experience Scales (TAPES). Pearson’s correlation coefficients were calculated between spatiotemporal of gait, balance scores, and TAPES domain outcomes.Results: Stride length (r=0.660), prosthetic step length (r=0.648) and intact step length (r=0.618) showed significant moderate positive correlations with psychosocial adjustment, while amputation limb stance time (r=-0.409) correlated weakly. Activity limitations negatively correlated with step/stride lengths (r range -0.781 to -0.784) and cadence (r=-0.538). Moreover, prosthesis satisfaction was associated with improved walking symmetry (r=0.445) and prosthetic stance time (r=0.388).Conclusion: Optimizing gait and balance in below-knee amputation can improve quality of life. Biomechanical factors should be targeted in rehab programs to enhance well-being.

Today, using new technologies is considered a vital factor in the sports tourism area. Tourist destinations try to use these technologies to create a competitive advantage to be a leader in this area. The use of these technologies brings lots of advantages. This research aims to identify the consequences of using new technologies in sports tourism. The research method is mixed with a sequential exploratory approach. In the first phase, the main indicators and components are identified using the online focus group research method, then in order to confirm them, a quantitative survey method was used. The data collection tools are semi-structured interviews collected from two focus groups including academic and executive participants related to the fields of sports management, sports tourism, and information technology. According to the research findings, 67 primary codes, 27 open codes, 13 axial codes, and 4 selective categories were extracted. In the quantitative phase of the research, all the values ​​related to the components and indicators were confirmed.  From the results of the present research, we can point out the benefits such as "smart health, smart sports tourism, green technologies, sustainable development (healthy and sustainable environment, dynamic and healthy economy, etc.), smart and sustainable sports tourism destinations" that were found to be the main advantages of using new technologies in sports tourism.
