Objective: The objective of the elaboration was to assess the degree of physical load in direct start preparation (DSP) during preparations of disabled sitting volleyball players for the Polish championships.
Material: Players of the “Start” Sports Club of the Disabled in Wroclaw who play sitting volleyball professionally participated in the study. The subjects of the study were men aged 17 to 53 (average age: 31.9); they have been playing sitting volleyball for 2.5 to 33 years. Twelve sitting volleyball players with various disabilities concerning uni- and bilateral amputation within the lower leg and thigh, with malformation and short lower limbs participated in the study.
Methods: The study involved assessment of the exercise capacity of sitting volleyball players during 7 training units in introductory and intensifying micro-cycles within DSP. Heart rate results at six moments (at the beginning, in the 10th minute, at the peak, in the 80th minute, in the 90th minute and in the 15th minute after the training) during each training unit in both micro-cycles were used. To register heart rate Polar S810i sport testers were used.
Results: Years of training significantly correlated with age of the participants. The participants were characterized by significantly lower resting heart rate in the intensifying micro-cycle than in the introductory microcycle which may result from adaptation of the body to physical effort. The largest differences in average heart rate values at the considered moments of training units in training micro-cycles within DSP were observed in the measurement of resting heat rate and final heart rate. Standard deviation in the introductory micro-cycle and the intensifying micro-cycle within DSP was growing in a linear manner, except for the peak heart rate index. Resting heart rate significantly impacted the value of heart rate during training units within DSP.
Conclusions: Volleyball players participating in the study were characterized by significantly lower resting hear rate in the intensifying micro-cycle than in the introductory micro-cycle within DSP which may result from adaptation of the body to physical effort. The lowest percentage difference of the average heart rate value occurred in the assessment of final heart rate, while at the remaining moments of training units heart rate values reached the same percentage value. The course of regeneration in both compared micro-cycles (DSP) was similar and it did not vary significantly. Restoring the value of resting heart rate occurred after more than 15 minutes after training.
