For the last decade there have been considerable discussion concerning the linearity / non-linearity of the oxygen uptake (O2) - power output (W) relationship with strong experimental evidence of non-linearity provided mainly by breath-by-breath measurements. In this study, we attempted to answer the question whether the O2 - W relationship in the Åstrand nomogram, as presented in the Textbook of Work Physiology, P.-O. Åstrand et al. (2003), page 281, based on the Douglas bag method, is indeed linear, as stated by the authors before, or if a change point in O2, described by Zoladz et al. (1998) Eur J Appl Physiol 78: 369-377, can possibly be detected in those data. The O2 - W data were taken from the Åstrand nomogram referenced above and from the Table 9.5 on page 282 in the same reference and tested for the presence of the change point in O2, using our two-phase model (see the reference above). In the first phase, a linear O2 - W relationship was assumed, whereas in the second one (above the so-called change point) an additional increase in O2 above the values expected from the linear model was allowed. It was found that in the data taken from the Åstrand nomogram (data for men), as well as in the data taken from the Table 9.5, statistically significant change points in O2 were present at the power output of 150 W. The documentation of the presence of a change point in the O2 - W relationship in the Åstrand data provides further evidence for the existence of a non-linearity in the O2 - W relationship in incremental exercise tests of humans, also in O2 data based upon the Douglas bag method.

According to the statistical data, there is being observed a definite increase in percentage of children affected by posture defects, particularly scolioses. The aquatic environment facilitates treatment of scolioses, since it provides relief conditions used in order to perform prophylactic, corrective and therapeutic tasks. Hydrokinetic therapy is one of the many rehabilitation methods. It seems, however, that corrective and therapeutic swimming is far too rarely used as an auxiliary measure for treatment of scolioses. This paper presents the concept of treatment of scolioses employing asymmetrical exercises in aquatic environment, the author of which in Poland is Iwanowski. In the study desk research of literature studies was applied along with the analysis of publications, including available study reports, articles, documents and also own video and photographic materials. The author suggests the concept of conservative treatment of scolioses through the application of asymmetrical swimming exercises in aquatic environment. Such procedure is efficient in preventing significant spinal deformations, which may protect against surgical intervention.

Grucza R. and Hänninen O.: Importance of dynamics of sweating in men during exercise. Acta Physiol. Pol. Influence of dynamics of sweating on rectal temperature increase was tested in 3 groups of men performing cycle exercise with intensity of 65, 90 and 120 W, respectively, in 22°C chamber temperature and 30% of relative air humidity. During exercise at 65 and 90 W the subjects wore suits while exercising with intensity of 120 W they wore only shorts. The dynamics of sweating was described by delay in onset of sweating and time constant of the reaction. Wearing caused significant increase in skin humidity and decreased evaporative rate of sweating. Sweat rate during steady state was related to the metabolic rate in naked (r = 0.89, p < 0.002) as well as in wearing subjects (r = 0.93, p < 0.01). Delay in onset of sweating was, in average, 5 min with a time constant of 7 min. Both factors showed a tendency to be shorter with increasing work intensity. Mean increase in rectal temperature was proportional to the intensity of exercise although the individual ATre correlated well with the dynamics of sweating in naked (r = 0.83, p < 0.01) and wearing subjects (r = 0.84, p < 0.01). Since ΔTre was smaller in subjects with shorter inertia time of sweating in response to beginning of exercise at the same intensity it is concluded that the dynamics of sweating can play an important role in limiting body temperature increase in working men.

The purpose of these studies was to determine how plasma levels of arginine vasopressin (pAVP) are related to workload, plasma osmolality (pOsm), blood volume (BV) and plasma angiotensin II (pAII) in exercising dogs. Measurements were made in dogs running on a treadmill at 7.5 km. hr⁻¹ at slopes of 0, 10% and 20% when they were hydrated ad lib and when they had been deprived of drinking water and also in dogs running on a 20% slope after an IV infusion of hypertonic NaCl. Dehydration increased pOsm by 6.6% and reduced BV by 10% in resting dogs. In dehydrated animals, pAVP, pAII and pOsm were elevated above hydrated levels at rest and during exercise at all three workloads. In hydrated dogs, pOsm rose during exercise at 10% and 20% slopes but pAVP rose above resting levels only at the highest workload and pAII was not affected by exercise. In dehydrated dogs, pOsm and pAVP rose during exercise at 10% and 20% slopes and pAII was elevated at the 20% slope. BV decreased during exercise at the highest workload in both hydrated and dehydrated animals. After hypertonic NaCl, pAVP rose during exercise but pOsm and pAII did not. The results suggest that both osmotic and nonosmotic factors contribute to the release of AVP in exercising dogs and that exercise leads to a leftward shift in the relationship of pAVP to pOSM which could be a result of reduced blood volume.

Aim of this study was to elucidate the influence of carbohydrate store modification on exercise capacity and catecholamine thresholds. Nine sedentary students and 10 endurance athletes volunteered for the study consisting of four sessions in one-week intervals. During control session (C) subjects performed graded exercise till exhaustion with workload increasing by 50 Watts every 3 min after an overnight fast. Blood lactate and catecholamines were determined at rest, after each workload and at exhaustion. In the evening preceding each of the remaining three sessions subjects performed glycogen reducing exercise lasting 1.5 hrs at 70% HRmax. Till next morning they did not eat any meal but drank water. Two hours before exercise subjects were given either a high-carbohydrate (H-CHO) or a low-carbohydrate (L-CHO) meal of approx. 1000 kcal or remained fasted (F). Depletion of carbohydrate stores enhanced contribution of fat-derived energy substrates at submaximal workloads, but did not influence either maximal oxygen consumption, workload and lactate concentration or lactate threshold. Low carbohydrate availability resulted in elevated concentration of catecholamines only in untrained subjects. Ingestion of a meal either high or low in carbohydrates diminished those changes. Catecholamine thresholds were similar in all sessions and higher in athletes’ group.
