Therefore, it was purposed to review scientific research results about the effects of HIIT programs on BDNF and cardiovascular health. Although there are research findings suggesting that HIIT may be an effective strategy for promoting elevation of BDNF concentrations, current research seems to be rather limited and inconclusive. It can be thought that exercise intensity is a factor affecting BDNF activation. In healthy people, there seems to be a positive linear relationship between exercise intensity and BDNF levels of acute exercise. However, further experimental studies are needed to elucidate the effect of HIIT on BDNF in humans with metabolic or cardiovascular diseases. However, it can be suggested that high intensity can be an significant achievement factor to design an effective exercise programs and the HIIT methodology has a critical importance for improving cardiovascular function, particularly in healthy individuals. In conclusion, while existing studies show that high-intensity interval training (HIIT) programs can improve cardiovascular health in some populations, further scientific research is needed to determine the efficiency of this strategy in producing physiological adaptation to exercise.

The data span the period from Kenyan independence in 1964 to 1989. Until now, no estimates of productivity for agriculture in Kenya have been available. Both multi-factor and labour productivity measures were constructed. Laspeyres indexing procedures were used. Our results indicate that while total production and input use have grown in the sector, productivity has stagnated through the period. Recent years have witnessed declining productivity. Attempts to use Cline's model to explain variations in productivity were unsuccessful. Coefficients of research and extension expenditures, education and weather variables were found to be statistically insignificant when these variables were regressed on productivity.

For this purpose, 36 male students (age: 21,4 ± 1,57 years; height: 175,2 ± 5,91 cm; weight: 68,7 ± 7,12 kg) who are studying at school of physical education and sport at the Gumushane University and have active athlete license in different sport branches participated in the study voluntarily. In the study, loaded-squat jump (SJLoaded) movement was practiced by using an external load equaled to 40% of their body weights in order to determine velocity parameters of the participants. Also, in order to determine the maximal dynamic strength of the participants, one repetition maximal strength (1RM) in the full back squat (SQFull) movement and anaerobic power tests were done. For the analysis of data, Shapiro-Wilk normality test, descriptive statistics and Pearson Correlation analysis were used. According to the analysis results, there is a positive and statistically significant relationship between the absolute and relative 1RM strength values in the SQFull movement and mean relative anaerobic power values together with peak velocity values obtained in the concentric phase of SJLoaded movement of participants. Also, it was found that there is a positive and statistically significant relationship between 1RM squat strength and both absolute maximal anaerobic power and absolute mean anaerobic power values. There was no statistically significant relationship was found except for this. As a result, since there is a significant relationship between strength and velocity values in terms of absolute and relative, it can be asserted that as the strength increases,

Data were obtained from secondary school students (n=565) studying in a province in western Turkey. "Socialization Scale" and "Socialization in Sports Scale" developed by Sahan (2007) were used as data collection tools. The reliability coefficient of the socialization scale was 0.77, and the reliability coefficient of the socialization in sports scale was 0.84. Descriptive statistics, Kolmogorov Smirnov test, Mann Whitney U test, and Kruskal Wallis test were used to analyze the data. As a result of the analysis, there were no differences in the socialization levels of the students in terms of age, licensed sports year, and sports branch variables (p>0.05), while a significant difference was found in the gender variable (p<0.05). Significant differences were observed in the socialization level of the students in terms of the class variable (p<0.05) and the father's educational status variable (p<0.01). A significant difference was found at the level of p<0.01 in the socialization, and the level of socialization in sports at the p<0.05 level of the students in terms of the mother's educational status variable. In terms of the frequency of doing sports, a significant difference was observed at the p<0.05 level in the socialization of students in sports.

We aim to compare static and dynamic balances in patients with acromegaly and healthy volunteers, and to evaluate the effects of exercise on balance in patients with acromegaly. Methods This prospective study included 25 patients with acromegaly followed at endocrinology clinic of Cerrahpasa Medical Faculty and 13 healthy volunteers. The acromegalic patients were divided into 2 groups. Group A (n = 11) attended an exercise program 3 days/week for 3 months, whereas group B (n = 14) and healthy volunteers (Group C) were exercise-free. Bipedal and unipedal stance static and dynamic balance tests were performed using a Prokin 252N device. Results The ages, demographic characteristics, and body compositions were similar. In acromegalic patients, the static balance parameters of displacement of center-of-pressure in anterior-posterior direction (C.o.P.Y) while eyes open (p = 0.002) and on left leg (p = 0.001), in left-right direction (C.o.P.X) on right leg (p = 0.03), eyes-closed average medio-lateral velocity (AMLV) (p = 0.001) and the dynamic parameter of forward/backward front/right standard deviation (FBFRSD) (p = 0.02) were significantly different from healthy controls. When the exercise effect on balance was evaluated between group A and B, there were significant improvements in most parameters of dynamic balance measurements of both forward-backward and medial-lateral sway (FBFRSD, FBDME, and RLBLSD) (p = 0.02, p = 0.02, and p = 0.004, respectively) after exercise in group A. Conclusions Patients with acromegaly had impairments at various static and dynamic balance parameters, especially in posterior direction. After a 3-month exercise program, the dynamic balance profoundly improved, but static balance was relatively preserved in patients with acromegaly.

We aimed to evaluate the role of regular exercise in amelioration of the impaired physical performance in acromegaly. Methods Patients with acromegaly were divided into two groups according to their participation in a prescheduled programme of exercise. Participants in the study group were exercised 3 days a week for 3 consecutive months. Exercise tolerance was evaluated by maximal oxygen consumption (VO 2 max) and time (T) taken to complete the Bruce protocol, muscle flexibility by the sit and reach test (SRT) and muscle strength by the hand grip strength test (HGST). Concomitantly, anthropometric assessment was performed using body mass index (BMI), waistto-hip ratio (WHR), skinfold measurements from 8 points, percentage body fat (PBF), fat mass (FM) and lean body mass (LBM). Results After 3 months of exercise, VO 2 max and T were higher in cases that exercised than in cases that did not (P = 0Á004 and P = 0Á001). Over 3 months, within the exercise group, VO 2 max and T of the Bruce protocol increased (P = 0Á003 and P = 0Á004) and heart rate during warming decreased (P = 0Á04). SRT increased within the exercise group after 3 months (P = 0Á004). HGSRT did not change significantly (right P = 0Á06 and left P = 0Á2). The sum of skinfolds, BMI, WHR and LBM remained stable over the study period (P = 0Á1, P = 0Á08, P = 0Á3 and P = 0Á09). PBF decreased slightly and FM decreased significantly over 3 months (P = 0Á05 and P = 0Á03). Conclusion Even short-term exercise may improve impaired physical performance, muscle activity and disturbed body fat composition in acromegaly.

This study presents the results of a skill training program which is based on &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;motor skill training&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; theory and using &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;bovine knees&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; to simulate a specific task as arthroscopy both in education and evaluation. The participants gave feedback regarding their expectations, fulfillment, and self-evaluation on the degree of their improvement levels, after which their skills were evaluated by an expert while they performed the arthroscopic procedure. During this evaluation of the task, a four-dimensional checklist which was prepared previously by the consensus of three experts was used, and a global grading of each rater was added at the end of the checklist. In this 2-day course, small group teaching sessions are integrated with active and experiential learning methods consisting of short presentations by the educators, demonstrations using joint models and audio-visual teaching material, and significant continuous feedback by the teachers during the proceedings. Participants&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; expectations and post-course feedback results were obtained using a brief questionnaire which involved mostly open-ended questions. The self-rating of &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;own basic diagnostic arthroscopy skill&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; on a scale of 0-10 was completed by the participants both previous to and following the course to establish a student-centered learning environment. Overall rating of the course was asked on a 1-5 (poor-excellent) Likert scale. The questioning of the participants who took part in the course during the last five terms involved a 100% feedback. The overall rating of the course was 4.36 ± 0.47 on the 1-5 scale. The majority of the participants (90%) mentioned that the course met their expectations. The most beneficial activities were accepted to be the arthroscopic procedure applications on bovine knee, repetition of the manipulations under the supervision of the trainers, continuous feedback by experienced staff, and chance for immediate correction during the procedures (35/64). Pre- and post-course self-ratings of the participants inquiring about their ability to perform an arthroscopy alone showed significant improvement (4.2 vs. 7.7 P = 0.000, paired samples t test). All participants were found to be competent in the evaluation of their diagnostic arthroscopy skills on bovine knees. To design a skill teaching course based on the needs of the trainees, focusing on basic motor skill training exercises, and using bovine knee as a simulator is a safe, inexpensive, humanistic, and replicable method that proves a foundation for basic arthroscopic skills learning prior to patient encounter.
