Abstract
Objective: Improvement of the aerobic capacity is the main goal of sports preparation and cardio-vascular rehabilitation.Cardio-plulmonary stress test is a useful tool for creation of individualized training programs. Design and method: In the present study we investigated the effect of training optimization aimed at improvement of aerobic functional abilities in male amateur sport-dancers. Two maximal cardio-respiratory tests were carried out on a treadmill (at the beginning and the end of an experimental 2-month period) and the dynamic in the maximal aerobic and total ergometric work capacity of the athletes was evaluated. During the 2-month period additional aerobic training sessions were included in the athletes’ program with intensity based on the individual anaerobic threshold (AnT) determined during the first test. These workloads consisted of 60-minute jogging sessions at intensity corresponding to 65 ÷ 80% of AnT (116 ÷ 145 beats min−1) twice weekly and trekking in spare time (3–4 times during the 2-month period). Results: The follow-up functional test revealed significant increase of the measured absolute and relative values of maximal oxygen uptake (8.5%, 9.2%, respectively; p* < 0.05), of achieved maximal treadmill speed (12.2%; p* < 0.05) and decrease in maximal pulmonary ventilation (−15.9%; p* < 0.05). These changes in the analyzed main functional parameters were accompanied by statistically significant decrease in maximal lactate concentration (−17.3%; p* < 0.05) and slight decrease of the registered maximal heart rate (−3 beats min−1; p > 0.05). Conclusions: The results allowed us to conclude that the training sessions added to the athletes’ program had contributed to the established substantial positive effect on the aerobic abilities. The results confirm the view that the application of individually tailored workloads in aerobic training programs is an important factor for optimization of metabolic energy pathways and a prerequisite for marked improvement of the organism functional work capacity.
