The introduction begins by highlighting the significance of both aerobic and anaerobic power in the performance of mountain biking races. Both aerobic and anaerobic power play a huge role in cross-country mountain banking due to the high-intensity energy involved. The significance of both ...

Part 1

The equipment used to assess VO2 max and lactate threshold includes the h/p/cosmos Pulsar 5.0 treadmill, the Cosmed Quark PFT Ergo testing equipment, the Cosmed V2 mask, the HR Belt Cosmed-ANT (w/transmitter), and a computer.

Calibration Processes

The preliminary step for the experiment is to perform the calibration of the equipment. The treadmill velocity should be calibrated by marking a point and noting the time it takes to complete a predetermined number of revolutions. This time is used to calculate the velocity by using the length of the belt, which should also be measured. These calibrations should be performed at different ...

Chi-square

The chi-square test is used to compare the theoretical and observed frequencies. The chi-square distribution is not symmetrical, as normal or t-distribution. The mean and standard deviation can be calculated for the normal, t-, and Poisson distribution. However, there is no need for these parameters in chi-square distribution. The significance levels are applied the same way as in other distributions. However, for chi-squared tests only one-tailed tests are applicable. Therefore, the calculated value is compared to the critical value for the right tail of the chi-distribution. The normal and t-distributions are applied only to numeric data, whereas the chi-squared ...

Introduction

XX century was characterized with the significant technological progress, which has improved the life of people. Numerous products and services became available, labor and domestic life became easier and more comfortable. However, waste problem is the other side of the technological progress. The solid, liquid and gas waste are formed, and thus land, natural water and air quality degrade. Therefore, in XXI century the research efforts are dedicated to development of methods for sustainable use of water, gas, and solid resources. Wastewater polluted with dye residuals originate from textile, leather and food industry. These industries produce goods that ...

Describe the underlying pathology of COPD and the common pathological characteristics of the condition. Discuss the impact these pathological changes have on normal function, including how alveolar ventilation might be different in Mr Wenham compared to a normal individual. The hallmark pathological attributes of chronic obstructive pulmonary disease (COPD) are one, poorly reversible airflow obstruction and two, a progressive atypical inflammatory response within the lungs. The abnormal inflammatory response denotes the responses of the innate and adaptive immune systems to long-standing exposure to noxious gases and particles especially cigarette smoke. Notably, all cigarette smokers have some degree of inflammation ...

QUELLENVERZEICHNIS EINLEITUNG Elektromagnetische Wellen sind die transversalen Wellen (Scherwellen), in denen der Vektor der Stärke der elektrischen und magnetischen Felder senkrecht zur Wellenausbreitungsrichtung schwingen, aber sie unterscheiden sich wesentlich von Wasserwellen, und dem Laut, da sie von der Quelle an den Empfä ...

Biology

Abstract This is a practical report on human physiology EMG. The experiment recruited 85 subjects to examine the level of the signal emanating from muscle contraction in the lab. Some of the participants were left-handed while some were right handed. Males and females with varying levels of activity were recruited. The results indicated that more males exhibited maximal compression force than females as attested by the higher numbers that returned quickly to half the clench force. The level of activity of the participants positively correlated to slow return to half of the maximal compression force and reduced signs of ...

Creatine is an amino acid. It is naturally occurring i.e. it is made in the body in the kidney, liver and pancreas. Creatine is obtained from foods such as meat and fish. In the body, creatine is converted to creatine phosphate and taken to reserves in the muscle. In the case of extreme intensity, short intervals of exercising such as weight lifting and sprinting it is used as an energy source. The storage form phosphocreatine is converted to the body's energy currency, ATP and used. The fact that it has this use has meant that athletes and body builders ...
