The level of efficiency of adult women in premature based on analysis of power input and power regulation stress test

Abstract

Introduction: Despite of sustainable living and increasing the knowledge of the future mothers, the number of preterm births have been at the same level through last years. In Poland it is stands at around 7%, comparable with other countries from European Union. The aim was to investigate the influence of prematurity on input power and regulation power during stress test in adult women. Achieved power depends on the level of physical efficiency and it is converted for specific VO2max values. Material and methods: 11 women born prematurely at age of 25-30 years (28,2± 2,3) did stress test according to W150 protocol. The control group consisted of 15 women born on time (27-32, 28,5±2,4). The statistical analysis included t-Student and Shapiro-Wilk tests. Index height/regulation power and BMI/ regulation power have been subjected to correlations. Results: There is statistical significant difference between input and regulation power in women born prematurely and the control group. Women from control group had significantly higher input and regulation power than women born premature. Moreover, there is proportionality between input and regulation power in two groups. Conclusions: 1. Prematurity influences the amount of power generated in women aged 25-30 negatively - women born prematurely are evidently less physically efficient than women born on time. 2. There is a connection between input and regulation power in both groups. Higher amounts of input power indicates higher amounts of regulation power. 3. There is no relationship between BMI and amounts of power in stress test.

The effects of differences in sleep quality and quantity on VO2max levels

“…Therefore, the study encourages everyone to increase their CRF as a precautionary measure in preventing diseases and reducing the death rate. In short, experts take a direct measurement of maximal oxygen consumption (VO 2max ) [3] using various methods, such as simple exercise protocols [4,5] or by employing sophisticated sports equipment in the testing process [6], to determine one's CRF levels. Some previous studies have been conducted to measure the VO 2max levels of particular groups based on different variables, namely ethnic differences [7], the demographic location of A -preparing concepts B -formulating methods C -conducting research D -processing results E -interpretation and conclusions F -editing the final version a country [8], types of daily activities [9], and anthropometry differences [10].…”
