The purpose of this study was 1) to compare the maximal oxygen uptake (VO2max) obtained in swimmers during tethered swimming, free swimming, and flume swimming, and 2) to determine whether an arm-ergometer test would provide comparable results. In the first experiments the VO2max for tethered swimming (2.67 +/- 0.26 l/min) and flume swimming (2.62 +/- 0.26 l/min) were not different (P greater than 0.05) and were highly correlated (r = 0.99). However, with arm ergometry a significantly lower VO2max (2.36 +/- 0.24 l/min) occurred from those found in the two swimming tests (P less than 0.05). Other experiments demonstrated that the tethered swimming VO2max (3.53 +/- 0.27 l/min) and the free swimming VO2max (3.55 +/- 0.28 l/min) also provide results that were similar (P greater than 0.05) and highly correlated with each other (r = 0.99). Differences between tethered and flume swimming, and tethered and free swimming were small, being 1.2 +/- 1.6% and 0.6 +/- 0.9%, respectively. Differences between tethered swimming and arm ergometry VO2max were large, 14.7 +/- 2.4%, despite the high correlation (r = 0.97) between these measurements. Predictions of a swimming VO2max from the arm-ergometer data yielded a considerable error (+/-7.1% and +/-7.4%). The present results indicate that flume swimming, free swimming, and tethered swimming yield essentially identical VO2max results.

Nine fully acclimatized men falling in the lean, medium and obese categories of body composition were observed during heat exposure periods for four days following acclimatization decay periods of various lengths in order to determine the effects of body composition on the decay and reinduction of acclimatization. The physiological variables taken into consideration were core temperature, “DuBois” mean skin temperature, heart rate, weight loss due to perspiration and the temperature differential between the core and surface. All of the men were subjected to an acclimatization schedule of twelve daily sessions in order to insure that they were all fully acclimatized. Three decay, or non-exposure, periods of four, eight and twelve days were each followed by four days of reinduction. It was determined that body composition does not affect the rate of decay or reinduction of acclimatization, although this parameter as well as the extent of decay and the duration of the reinduction period does affect the physiological variables monitored in this study.

Cerebral palsy is one of the known and famous types of neurological impairment among children across the globe. The study aimed to see the effect of graded conditioning and exercises over some of the physiological variables of children with cerebral palsy. For the purpose of the study 20 children with cerebral palsy were selected and were divided into two groups of ten each the experimental group were given the treatment and the other was the kept as control group for twelve weeks. To obtain the results the analysis of co-variance was applied and it was seen that resting heart rate (.006), triceps girth (.002), suprailliac girth (.002), abdominal umbilicus (.001), sub-scapular girth (.009), positive breath holding capacity (.007) and cardio-respiratory endurance (.001) showed positive significance at .005 level. As after twelve weeks of graded conditioning it can be seen that most of the physiological variables and variables of body composition showed great signs of improvement and showed positive significance, so it can be concluded that with good graded training (according to their need and capability) the positive physiological improvement can be made among children with cerebral palsy.

Ergometer Test

Little information is available about the physical fitness of opera singers. The aim of this study is to measure cardiac engagement during rehearsals and to test both cardiovascular fitness and body composition in a group of opera singers. Thirty-two opera singers (17 female and 15 male) were enrolled for the assessment of body composition by bio impedance, of cardiovascular fitness by submaximal exercise test on a cycle ergometer and the physical effort during singing. Anthropometric parameters showed an overweight condition mainly due to an increase in fat mass. Watts reached during the cycle ergometer test were below the normal range for the general population. During rehearsals, singers have reached 95% of the maximum heart rate. Nowadays, opera singers show low levels of physical fitness, but singing is an activity that requires a high heart effort. Therefore, it is recommended to involve such professionals in a gradual and individualized physical training program in order to avoid fatigue during performances and achieve a better singing performance.

Anesthesia for children is attenuated by the changes that occur during growth anddevelopment. The dose of the drug is affected by the size and maturation processesof purification, as well as by the changing body composition that occurs with age.All organ systems undergo these maturation changes and most are completed in thefirst years of life. Normal physiological variables in childhood and childhood are quitedifferent from those of adults. The central nervous, cardiovascular and respiratorysystems are particularly important. Brain immaturity and plasticity impact drug sensitivity,pain responses and behavior and increase the potential damage of apoptosiswith anesthesia. The heart experiences a transition from fetal to adult circulationduring the first weeks of life. Congenital defects not diagnosed are not uncommon.The newborn is very susceptible to conditions that trigger an increase in pulmonaryvascular resistance, with reversion to fetal circulatory patterns. The anatomy and respiratorymechanics affect the apnea propensity, the maintenance of the airways, theartificial ventilation modalities, the absorption of inhalant agents and the size of thetracheal tubes. The metabolic rate and oxygen requirements increase with age. Thisphysiology influences various aspects that include the desaturation rate during apnea,hypoglycemia during hunger, cardiac output, drug metabolism, fluid requirements andheat production or loss.Key words: Physiology–respiratory system–Anatomy–bronchomotor tone–functionalresidual capacity–tracheobronchial tree–ventilationperfusion

SummaryStudy aim: running economy (RE) is important indicator of endurance performance. During puberty dynamic changes in body composition and function are observed, as such RE is also expected to change. The aim of the study was to compare the running economy (RE) in overweight and normoweight boys during a running exercise performed with constant velocity, and the assessment of changes in RE during puberty.Material and methods: the RE of the subjects was evaluated twice: at the age of 11–12 and two years later. 18 overweight and 17 normal weight boys performed a graded test and a week later a submaximal run on a mechanical treadmill. During the exercise, physiological variables (oxygen uptake, heart rate, pulmonary ventilation, tidal volume and breathing frequency) were measured.Results: the intensity of work in both tests (%VO2max, %HRmax) was significantly higher in the overweight boys and decreased with age (non significantly) in both groups. The physiological response during the run in the overweight boys was significantly higher compared to normal weight. When the oxygen uptake was expressed as VO2.BM–0.75, the RE was similar in normal weight and overweight boys. During puberty, the inter-group differences in the metabolic cost of work stay at a relatively stable level.Conclusions: the lowered endurance performance in the overweight boys during puberty remains unchanged. The changes in physiological variables during puberty in both groups occurred in a similar way – the body composition did not influence the course of these changes in puberty.

Bicycle Ergometer Test

The maximal oxygen uptake and body composition of 30 exceptional athletes who have trained extensively with weights was measured. The sample included 3 world record holders, 8 other world class athletes, and 19 national class competitors. The sports represented were shot-putting, discus throwing, body building, power lifting, wrestling, and olympic lifting. Vo2max as determined on a bicycle ergometer by the open-circuit method was 4.6 +/- 0.7 1-min-1 (mean +/- SD) (48.8 +/- 7 ml-kg-1., 56.4 +/- 8.6 ml-(kg LBW)-1). The mean maximal heart rate was 185.3 +/- 11.6 beats-min-1. The subjects attained a work rate of 1,728.2 +/- 223 kpm-min-1 on a continuous progressive bicycle ergometer test and had mean maximal ventilations of 152.5 +/- 27.7 1-min-1 BTPS. Body composition was determined by densitometry. Body weight averaged 96.0 +/- 14.9 kg, with mean percent fat of 13.8 +/- 4.5. The results of this study indicate that exceptional weight-trained athletes are within the normal college-age population range in body fat and of somewhat higher physical working capacity.
