“…This value is close to the value of 17.2 W/kg^0.75 found in [96], where lighter rats of 0.180-0.220 kg underwent strenuous exercise which was stopped when the rats were exhausted and refused to run even with electrical stimulations. [96] reports values as high as 24 W/kg^0.75 for rats. Typical peak metabolic rates for humans are around 30 W/kg^0.75.…”

This article presents differential equations for locomotive force and velocity during cross-country skiing. A muscle's work power is modelled. Thereafter, a locomotive force that depends on the skier's velocity is constructed. The external forces aerodynamic drag, friction forces and the force of gravity are incorporated in order to provide the equation of motion. Some allometric mass scaling relations are established and used to analyse the effect of a skier's mass on velocity. The model is tested by using a GPS instrument. We compare analytically and experimentally determined skiing distances and velocities as functions of time, and under different conditions. The article provides tools useful for practising athletes and coaches.

Maternal exercise during pregnancy as one of the critical periods can have significant delayed effect in the offsprring's fetal imprinting of future development until adult age; adequate and voluntary exercise is provided, not a forced one as a stress. Spontaneous physical activity of the offspring until adult age can be increased, and body composition, cardiac micro structure and reactibility (greater resistance to noxi), vasomotor function, glucose metabolism, insulin sensitivity along with related diseases (diabetes) can be positively influenced. Bone development and also the enhancement of brain function and learning sensitivity can be improved as revealed in a number of experimental model animal studies. Exercise during pregnancy was also shown to compensate in the offspring the detrimental effect of inadequate, e.g. high fat diets. Possibility of introducing significant modifications of the programming of the offspring's desirable development and health status by adequate and physiological maternal exercise during pregnancy was supported also by some observations in humans. Keywords IntroductionThe level of physical activity (PA) and exercise (Ex) is an important environmental stimulus which has significant effect on a number of metabolic, humoral, functional, morphological, psychological and other characteristics of the organism which can manifest not only at present, but also as delayed consequences when implemented since the very beginning of life. Such effects depend on the character, intensity, frequency, duration of PA régimes and/or Ex, and the reaction and consequences can be also further modified by eventual adaptation to them when applied gradually and repeatedly during appropriate periods of time. Increased physical fitness, reduced adiposity along with reduced metabolic, musculoskeletal and psychological problems can result from adequate exercise, especially when applied during growth [1,2]. On the other hand, sudden forced implementation of increased Ex can become a stress with undesirable results as revealed e.g. in experimental models [3,4,5].Previous studies on the impact of Ex which modifies significantly energy balance and turnover showed also that the earlier such a stimulus is implemented and the longer it lasts, the more apparent are its manifestations; the adequacy of such a stimulus is essential, and should always have a character as related to the level of development of the organism when Ex is started to be implemented. Moreover, this effect can appear and has a special character when applied through the régime of PA of the pregnant mother [3][4][5][6].Fetal origin hypothesis of morbidity [4,5,7,8,9] and metabolic imprinting by prenatal, perinatal and postnatal factors [6][7][8][9][10] concern also PA and Ex. Their impact can be transferred during pregnancy on the fetus due to physical activity régimes and reactive changes to them of the pregnant mother, and could manifest significantly in the offspring during its own postnatal period up to the adult age. The effect of PA ...

“…Some animal studies have suggested that, in contrast to exercise of low to-moderate intensity, strenuous exercise may affect fetal and maternal body weight gain 20 . However, others have reported no effect on either maternal body weight gain 21 or fetal body weight 22 .…”

DNA damage in Wistar Kyoto rats exercised during pregnancy

et al. 2017

Purpose: To evaluate DNA damage levels in pregnant rats undergoing a treadmill exercise program. Methods: Wistar Kyoto rats were allocated into two groups (n= 5 animals/group): non-exercise and exercise. The pregnant rats were underwent an exercise protocol on a treadmill throughout pregnancy. Exercise intensity was set at 50% of maximal capacity during maximal exercise testing performed before mating. Body weight, blood pressure and glucose levels, and triglyceride concentration were measured during pregnancy. At day 10 post-natal, the animals were euthanized and maternal blood samples were collected for DNA damage. Results: Blood pressure and glucose levels and biochemical measurements showed no significant differences. Increased DNA damage levels were found in exercise group compared to those of non-exercise group (p<0.05). Conclusion:The exercise intensity protocol used in the study might have been exhaustive leading to maternal increased DNA damage levels, demonstrating the relevance of an adequate protocol of physical exercise.
