Ampute Futbol Maçına Verilen Fizyolojik Yanıtların ve Hareket Profillerinin İncelenmesi

Abstract

The aim of this study was to examine the activity profiles and physiological responses during amputee soccer game. Nine amputee soccer players took part in this study voluntarily. In the first phase, amputee soccer players’ demographic information was obtained and anthropometric measurements were conducted. Following this phase, individual maximal heart rate (HRmax) was determined by the progressive running test, namely modified shuttle test. Minimum 2 matches for each amputee soccer player was set as criteria and therefore, activity profiles and physiological responses during amputee soccer game were determined with 22 matches. Basal HR and blood lactate (La) concentration of amputee soccer players were determined prior to each amputee soccer game. La response and rating of perceived exertion (RPE) after first and second halves and HR tracking during amputee soccer game were determined and these parameters were considered as physiological responses. Peak HR (HRpeak) was taken to be the highest HR achieved and mean HR (HRmean) was tracked during and first and second halves. Activity profiles were as follows: The mean total distance covered, the mean total distance covered at various speed categories, percentages of the mean total distance covered at various speed categories, maximal speed (Speedmax) attained and time spent at HRpeak of percentage of individual HRmax during amputee soccer game. The dependent sample t-tests were used to compare the activity profiles and physiological responses between the halves. Comparison of the mean total distance covered at various speed categories and percentages of the mean total distance covered at various speed categories between halves were analysed by 2x5 (half x speed category) repeated measures analysis of variance. Comparison of time spent at HRpeak of percentage of individual HRmax between halves were analysed by 2x4 (half x HRmax category) repeated measures analysis of variance. When a significant F value was found, the Bonferroni post hoc test was applied. Results for physiological responses revealed a higher HRmean in the first half compared to second half (p<0.05) whereas HRpeak, HR%, RPE and La responses between the halves were similar (p>0.05). Activity profile results showed that Speedmax attained were not statistically different between the halves (p>0.05). In contrast, mean total distance covered in the halves were found to be different (p<0.05). There was a significant halve and speed category effect in amputee soccer game (p<0.05) and significant half x speed category interaction was also observed (p<0.05). On the other hand, difference between the halves in the percentages of the mean total distance covered at various speed categories were not evident (p>0.05). Half x speed category percentage interaction was not found (p>0.05) whereas effect of the percentage of mean total distance covered at five speed categories was significant (p<0.05). There was no significant difference between the halves in time spent at four different HRpeak %of percentage of individual HRmax between halves (p>0.05). On the contrary, there was a significant difference in time spent at four different HRpeak % of individual HRmax between halves (p<0.05). Similarly, half x HRpeak % interaction was found. In conclusion, the results of the current study showed that physiological responses during amputee soccer game were not differed between the halves except HRmean response. Results of the activity profiles revealed similar Speedmax attained in the halves whereas total distance covered, percentage of the mean total distance covered at various speed categories and time spent at HRpeak% during amputee soccer game were differed according to the halves.
