Relationship between achievement motivation and the selected parameters of acid-base balance at maximum endurance performance
Abstract
The aim of this study was to analyze the correlation between the dimensions of achievement motivation gained from the questionnaire LMI and selected parameters of acid-base balance (pH, H +, BB, BE, O2SAT) that evaluated the maximum endurance performance. Participants were representatives of the junior and senior national team Czech Republic in the Olympic triathlon in the 28 (8 women and 20 men) aged 20.4 +- 2.1 years.
To evaluate the performance motivational component we used standardized psychological questionnaire LMI achievement motivation. For maximum performance was chosen step test on a bicycle ergometer.
The length of each step was two minutes, the load intensity is escalated about 20 W at the beginning of each subsequent segment begun. At the end of the test, blood sample was taken for analysis of selected values of acid-base balance.
To analyze the relationships between parameters were used Pearson correlation analysis. Statistical significance was evaluated level of 0.05.
A statistically significant relationship was confirmed only in the dimension of confidence in success (r DU-pH = -0.48, r DU-H + = 0.47; r DU-BE = - 0.47, r DU-BB = -0.46 , r DU- O2sat = - 0,47). The results obtained in the test of achievement motivation in most cases not affect the use for maximum performance.
The main role will be more in other areas, eg. voluntary processes. Confidence in the success could volitional processes during endurance activities positively encouraged.
