PHYSIOLOGICAL AND BIOCHEMICAL INDICATORS OF PHYSICAL PERFORMANCE DURING EXERCISE TEST (TREADMILL AND BICYCLE ERGOMETER)
Abstract
Abstract. Aim. The paper aims to compare the data of functional and biochemical indicators of the same athletes during treadmill and bicycle ergometer exercise tests. Materials and methods. Twelve apparently healthy males aged 17–23 years involved in middle-distance running participated in the study. Treadmill and bicycle ergometer exercise tests with stepwise loading were used for the purpose of the study. Functional and biochemical indicators were assessed, including heart rate (HR), anaerobic threshold (AT), speed of recovery, serum lactate and glucose. Results. The treadmill exercise test was associated with significantly higher HRmax, HRAT, and serum glucose values. Serum lactate was higher during bicycle ergometer test. In the recovery period, serum lactate remained almost unchanged after bicycle ergometer exercise and insignificantly reduced after treadmill exercise, which confirmed the shortage of a 10-minute recovery period for normalizing serum lactate and glucose and carbohydrate homeostasis. Conclusion. The results obtained confirm the differences between functional and biochemical indicators at anaerobic threshold and peak exercise of different exercise tests. The assessment and interpretation of functional and biochemical indicators after exercise tests require an individual approach.
