Background Understanding the impact of altitude on muscle damage and oxidative stress is essential for optimizing training and recovery strategies for athletes exposed to high-altitude conditions. Therefore, this study aimed to investigate the effects of acute exercise at different altitudes on oxidative stress and muscle damage. Methods A total of twelve elite long-distance runners (mean age: 20.3 +/- 1.5 years) from different branches participated in the study. The exercise protocol was the Bruce submaximal treadmill exercise test, which was conducted under three simulated hypoxic conditions (at 1,700 m, 2,450 m, and 3,200 m) and one normoxic condition (sea level). All measurements took place at the same time of the day. After the exercise protocol, 5 ml venous blood samples were taken from the participants, while heart rate and oxygen saturation were monitored at the 3rd, 6th, 9th, and 12th minutes during the exercise. Results Significant altitude-dependent variations were observed in oxidative stress markers, with total oxidant status (TOS) (p = 0.017) and malondialdehyde (MDA) (p < 0.001) levels increasing at higher altitudes, while total antioxidant status (TAS) (p < 0.001) exhibited an elevation and oxidative stress index (OSI) (p < 0.001) demonstrated a decline as altitude increased. However, no significant difference was found in creatine kinase (CK, p = 0.059) levels. Additionally, there were significant differences in the oxygen saturation measurement taken at the 3rd (p < 0.001), 6th (p < 0.001), 9th (p < 0.001), and 12th (p < 0.001), minutes following the exercise session. There was no difference in the pulse measurement taken at the 3rd and 12th minutes, but a difference was observed at the 6th and 9th minutes post-exercise (p < 0.01). Conclusions In conclusion, the study determined that endurance exercises performed under simulated normobaric hypoxia at different altitudes increased TAS and reduced OSI in elite long-distance runners. The increase in TAS and the reduction in OSI were more pronounced at higher altitudes, particularly at 2,450 m and 3,200 m, compared to sea level. These findings highlight the need for altitude-specific training and recovery strategies to minimize oxidative stress and muscle damage in athletes.
Assessment of Youth Leaders' Physical Activity Levels
(Anadolu Univ, 2022) Oner, Salih; Boztas, Ahmet Vahit
Aim: The purpose of this study is to investigate the levels of physical activity among youth leaders working in Turkey's Eastern Anatolia region. Methods: The purpose of this study is to examine the levels of physical activity among youth leaders operating in the Eastern United States. The study's field includes 111 boys and 60 girls, for a total of 171 young leaders operating in the Eastern Anatolia Region. The sample includes 79 men and 49 women, for a total of 128 youth leaders in these provinces. The study rely on the short form of the International Physical Activity Questionnaire (IPAQ). The data is analyzed using mean and standard deviation analysis techniques, with the Mann-Witney-U and Kruskal Wallis test used to evaluate differences. The results is statistically significant at p < 0.05. Results: According to the obtained results, the Physical Activity (FA) levels of the youth leaders are 1742.3 +/- 11.81.0 MET-min/wk, 20.3% inactive, 21.9% minimally active, 57.8% in terms of FA category. It is discovered to belong to the category of extremely active. Women have higher levels of physical activity than men, with a statistically significant difference (p<0.05).At the FA level according to the provinces, Erzurum province is seen as very active and Elazig province is in the inactive category. Conclusion: As a result, it is determined that women are better than men in the FA levels of youth leaders by gender. For the provinces that are inactive in the distribution of youth leaders' FA levels by provinces, programs to improve physical activity for youth leaders are also; it can be said that the quality of life can be increased by explaining the importance of physical activity through seminars and symposiums.
Effects of High Intensity Interval Training on Trace Minerals and Physiological Parameters in Tennis Players
(Iermakov S S, 2022) Oner, Salih; Yasul, Yavuz
Background and Study Aim This study investigated the effects of HIIT (high-intensity interval training) implementations on some serum elements, resting heart rate, total body weight, and BMI parameters in tennis players. Material and Methods The study group consisted of 20 athletes (aged 18-22) who were actively playing tennis. The athletes were divided into experimental (n=10) and control (n=10) group. To assign participants to these groups homogeneously, preliminary measurements were made before the study, and the results were used for clustering analysis. While the control group continued their regular tennis training, the experimental group was given additional HIIT three days a week besides regular tennis training. Measurements of BMI, resting heart rate, and body weight were taken, and serum samples were collected before and after training from both groups. The SPSS package program was used in data analysis. The level of significance was set at p<0.05 in the tests. Participants showed significant differences in sodium, calcium, iron, resting heart rate, weight, and BMI parameters between groups (p<0.05). Results However, no significant differences between the groups were found in potassium, chlorine, and magnesium parameters (p>0.05). The within-group measurements of sodium, calcium, resting heart rate, weight and BMI levels decreased in the experimental group in the post-test, while iron levels were higher in the post-test compared to the pre-test value (p<0.05). On the other hand, the pre-test and post-test values were similar within the control group, and there were no significant differences (p >0.05). Conclusions Training remodelled with HIIT implementation can affect athletes' element levels, BMI, total body weight, and resting heart rate. In addition, the increase in iron levels due to HIIT in the experimental group was important. We believe that this may affect both muscle contraction functions and the efficiency performance output. Lastly, due to the decrease of calcium and sodium elements with HIIT implementations, we suggest that HIIT applications should not be performed unsupervised. In addition, by tracking the element levels of athletes, they should be supported with supplements or nutritional meals in line with expert advice when necessary.
Strength Development, Muscle and Tissue Damage in Different Training Models
(Sciencedomain int, 2021) Akbulut, Taner; Cinar, Vedat; Oner, Salih; Erdogan, Ramazan
Purpose: The aim of this study was to determine the effects of during six weeks core and weight lifting trainings on strength development, muscle and tissue damage which may occur. Method: The research group consisted of sixteen volunteers who participated in the same age group. Participants were divided into two groups, core training group (n: 8) and weight lifting training group (n: 8). Participants continued to the program for the group to which the belonged lasted for three days a week for six weeks. Participant's performance measures (Back and leg strength, hand grip strength, vertical jump) were taken and blood samples were taken twice at rest before and at the end of the training sessions. AST, ALT, LDH, CK and CK-MB levels were determined in the blood samples taken. SPSS 22 package program was used in the analysis of the obtained data. Paired samples t test was used for intra-group comparisons. Results: When intra-group analyses are made; there were significant differences in the leg strength, vertical jump, CK and CK-MB values of the weight lifting training group, it was determined that only differences in back and leg strength values occurred in the core training group(p<0,05). Conclusion: As a result, both core and weight lifting training have led to some improvement in strength parameters. It can be said that especially weight lifting training also causes muscle damage as well as strength development.
