Relative Indicators and Predicative Ability of Some Biological Variables on Cardiac Neural Activity for Volleyball Players

Abstract

Mohammed Nader Shalaby, Marwa Ahmed Fadl.

The current research aims to study the relative indicators and predictive ability of some biological variables for the cardiac neural activity of volleyball players. The researchers used the descriptive approach as it is suitable for these research objectives. The researchers used the descriptive approach as it is suitable for these research objectives. Results indicated that:
• There are positive correlations between biological variables and Heart Rate Variability for the following variables: VC max – PEF – VC – EV – IV – HR max – CO2 max. These variables are considered as indicators for evaluating the functional training status of volleyball players.
• Relative contribution of biological variables was between (31.40%) as the least value fir VC max and (97.25%) as the highest value for the following nine variables: VC max + PEF + VC + EV + IV + HR max + VO2 max + CO2 max. these variables contribute collectively in HRV for volleyball players.
• Cumulative Power predicative equation came as follows: HRV = 21.213 + (20.217 x VC max) + (10.652 x PEF) + 22.848 x VC) + (4.349 x EV) + (406.199 x IV) + (227.298 x IC) + (3.650 x HR max) + (762.457 x VO2 max) + (142.634 x CO2 max).
