Comparing VO2max Improvement in Five Training Methods
Moxnes, John Fredrik; Hausken, Kjell (2012)This paper presents a theoretical study comparing the improvement of the whole body maximum oxygen uptake (maximum aerobic power or VO2max) when training at different intensities and with different methods matched for ... -
Introducing Randomness into First-Order and Second-Order Deterministic Differential Equations
Moxnes, John Fredrik; Hausken, Kjell (2010)We incorporate randomness into deterministic theories and compare analytically and numerically some well-known stochastic theories: the Liouville process, the Ornstein-Uhlenbeck process, and a process that is Gaussian and ... -
On the Big Bang Cosmology as a Kinematic Event in Newtonian Cosmology Modified by Dark Energy
Moxnes, John Fredrik; Hausken, Kjell (2012)The concepts dark matter and dark energy are commonly used to explain the universe. The dark energy can be conceived as a property of vacuum or the ether. However, a quite different but also common approach is to modify ... -
On the Kinetics of Anaerobic Power
Moxnes, John Fredrik; Hausken, Kjell; Sandbakk, Øyvind (2012)Background This study investigated two different mathematical models for the kinetics of anaerobic power. Model 1 assumes that the work power is linear with the work rate, while Model 2 assumes a linear relationship ... -
A simulation of cross-country skiing on varying terrain by using a mathematical power balance model
Moxnes, John Fredrik; Sandbakk, Øyvind; Hausken, Kjell (2013)The current study simulated cross-country skiing on varying terrain by using a power balance model. By applying the hypothetical inductive deductive method, we compared the simulated position along the track with actual ... -
Stochastic Analysis of England Grain Prices 1750-1850
Moxnes, John Fredrik; Hausken, Kjell (2012)We study the prices of grain in England 1750-1850, with special attention to the Tamboro volcano eruption time period 1815-1820. Two different types of time series are constructed and compared with the historical data. ... -
Stochastic Theories and Deterministic Differential Equations
Moxnes, John Fredrik; Hausken, Kjell (2010-05)We discuss the concept of “hydrodynamic” stochastic theory, which is not based on the traditional Markovian concept. A Wigner function developed for friction is used for the study of operators in quantum physics, and for ... -
Using the Power Balance Model to Simulate Cross-Country Skiing on Varying Terrain
Moxnes, John Fredrik; Sandbakk, Øyvind; Hausken, Kjell (2014)The current study adapts the power balance model to simulate cross-country skiing on varying terrain. We assumed that the skier’s locomotive power at a self-chosen pace is a function of speed, which is impacted by friction, ...
