Background : High altitude environments can cause a range of physiological changes in the body, and adolescents may be particularly vulnerable to the effects of altitude sickness. Acetazolamide has been shown to be an effective treatment for altitude sickness, but further research is needed to determine its impact on physiological variables among adolescents at high altitude. Aim: The aim of this study was to investigate the effects of acetazolamide in adolescents over 17 days at high altitude. Materials and Methods: Twenty-five healthy adolescents volunteered for this study and were randomly separated into control group (CG, n=12) and acetazolamide group (AG, n=13). AG took 250mg of acetazolamide. Resting Heart Rate (RHR) and Acute Mountain Sickness (AMS) using the Lake Louise questionnaire were measured each morning and afternoon during field testing; Resting Blood Pressure (RBP) was measured each afternoon. Pre- and post-blood samples (haemoglobin (Hb) and haematocrit (Hct)) were taken at sea level (SL) one week before departure and within 40 hours on return to SL. Results : Significant differences between groups for RHR on days 2, 3 and 5; systolic blood pressures for day 4 and 13 ( P <0.05). No significant difference between groups for diastolic blood pressure, pre- and post-altitude for Hb, Hct and PV. AMS scores did not differ from the two groups except on morning of day 12 ( P <0.05). Discussion and Conclusion : Results revealed that acetazolamide did not significantly induce changes to adolescents’ AMS scores and physiological changes. However, adolescents may consume acetazolamide to achieve lower RHR that may enable them to accommodate to HA, prolonging exercise in similar environments.

The aim of this study was to analyze the phenomenology of sports club customers' gratitude. The method of this research is qualitative and its approach is hermeneutic phenomenology. The participants of this research were 14 customers of sports clubs who had experienced gratitude. These people were selected, using purposeful sampling based on theoretical saturation. Semi-structured interviews were used to collect data. In this study, the strategies of credibility, transferability, conformability, process audit study, and inter-coder agreement were employed to assess the reliability and trustworthiness of the results. The data was analyzed using Van Manen's (2016) phenomenological method in three stages of coding. Based on the holistic and selective analysis, 6 main themes with 14 sub-themes emerged from the combination of 53 sub-themes. It was also found that the behavioral performance of employees, organizational factors, and individual factors are the drivers of customer appreciation, sports club customer appreciation has two behavioral and emotional aspects, and grateful customers show favorable psychological and behavioral reactions. Therefore, it can be pointed out that customer appreciation is the result of an involuntary exchange process that is accompanied by favorable psychological and behavioral reactions. In addition, any increase in customer appreciation depends on the customer's self-evaluation, the behavioral performance of employees and organizational factors.
