Screening Survey

This work was conducted with the support of 19-20 years old students during physical education classes across the 1st Semester of AY 2017/2018 at the Bucharest University of Economic Study.  The study case starts with the premise that all subjects were under/medium level trained and it focuses on a cross-screening survey which includes body mass index, oxygen consumption, heart rate activity, oximetry, spirometry and caloric consumption rate.  The participation of subjects was voluntary and for this they signed a written agreement which allows the results to be published. The surveillance process was made using approved devices and a previously tested methodology.  The final results revealed that there is no correlation between VO2, BMI and FVC for the subjects of the group.

Musical Rhythms

The aim of this study was to investigate adaptations acute heart rate (HR) and oxygen consumption (VO2) in an experimental protocol of step training with different combinations of platform height (15.2, 20.3 and 25.4 cm) and musical rhythms (125, 135 and 145 bpm). Thirty-five women were randomly selected, (mean ± DP) aged 21.6 ± 1.8 years, body weight of 57.8 ± 8.2 kg, height of 162.6 ± 6.8 cm, body mass index of 21.8 ± 2.5 kg m-2 and fat percentage (% Fat) of 24.8 ± 4.4%, with at least six months experience in step training sessions, and a frequency of at least two days a week. Techniques of descriptive and inferential statistics were employed. A significant difference was detected for the HR and VO2 in relation to the increase in step platform height and in musical rhythm for all the combinations, except for three situations. From the obtained results, we can infer that the cardiovascular and metabolic responses increase or decrease according to the musical rhythm and/or platform height.

The heart rate, ventilation rate, oxygen consumption rate, and mechanical efficiency responses of a subject to a series of temperatures, relative humidities, and workloads were observed. A quadratic prediction equation of each of the responses as steady-state functions of the independent variables was derived. Each of the equations represents a four-dimensional hypersurface. For the heart rate, ventilation rate, and oxygen consumption rate the hypersurfaces are quite similar, the responses increasing rapidly with respect to workload and about one-third as rapidly with respect to temperature. The effect of relative humidity was present primarily as interactions. Mechanical efficiency was represented by a more complex hypersurface. In three dimensions, with relative humidity as a parameter, the response was a saddle-shaped surface with the highest efficiency at a condition of low temperature, high workload. At constant environment, the heart rate responses of 19 subjects to workloads was observed and found to be linear with a normal distribution of slopes. Submitted on May 2, 1960

The research was aimed at determining the changes in functional abilities of women under the influence of recreational swimming. The sampled population consisted of healthy women, aged 35 to 45, chronologically, with a dominant sedentary lifestyle. The assessment of functional ability was tested using the following variables: vital capacity, heart rate at rest, working heart rate, systolic blood pressure, diastolic blood pressure and relative oxygen consumption. Basic parameters of descriptive statistics were calculated for all the results, whereas the T-test was applied to determine the difference between the initial and final measurement. The results of the research showed that there were statistically significant changes of vital capacity after three months of recreational swimming (p = 0.000), heart rate at rest (p = 0.000) and relative oxygen consumption (p = 0.000). The research found that the programme of recreational swimming with sedentary middle-aged women can act effectively to change functional abilities.

Relative Potencies

Relative sensitivities of various criteria, which were found to be suitable qualitative indicators of thyroxine and triiodothyronine, were determined by calculating and comparing the amounts of each hormone necessary to maintain the control level of each criterion in thiouracil-treated chicks. Relative sensitivities of the criteria used for determining action of thyroxine were: feather length > rectal temperature > weight of the thyroid > oxygen consumption rate > heart rate > suffocation time; of triiodothyronine: feather length > rectal temperature > suffocation time > thyroid weight > oxygen consumption rate > heart rate. Relative potencies of thyroxine and triiodothyronine were determined by comparing the magnitudes of responses of each of the above criteria to equal or equivalent quantities of these two hormones. Thyroxine and triiodothyronine exhibited equal potency in affecting the above criteria in thiouracil-treated chicks except for a) antigoiterogenic action in which case thyroxine was more potent than triiodothyronine and possibly b) elevation of rectal temperature for which action triiodothyronine appeared to be the more potent hormone.

The effects of thermal radiation on heart rate, ventilation rate, and oxygen consumption rate were investigated at various conditions of dry-bulb temperature, air velocity, and exercise. Ventilation rate and oxygen consumption rate were essentially independent of thermal radiation under all the environmental conditions investigated. However, heart rate increased appreciably with increases in thermal radiation provided the environment was already warm or hot. In the range between 70 and 100 F dry bulb, a 7 F increase in mean radiant temperature was found to elicit the same average increase in heart rate as a 1 F increase in dry bulb. For a cool environment the response tended to be reversed with the heart rate decreasing as the environment was made more comfortable by the addition of thermal radiation. Exercise shifted the point at which this reversal occurred toward lower temperatures. heat stress; heart rate; thermal intensity Submitted on July 16, 1964

Bicycle becomes famous transportation as efforts cut greenhouse gas emission. Comfortable, less injured, and less energy are the requirement of bicycle that urban communities wanted. Seat tube angle (STA) is an angle formed between seat tube and chain stay, which has influences on the above requirement. The objective of this study is to investigate the effect of varying seat tube angle (STA) on the muscle tension leg riders during cycling. This study used changeable frame bicycle into several STA. A total five cycling trials with body mass index 21-25, were conducted at seventeen STA’s position (form 62° until 78°). Muscle tension leg was measured before and after cycling by using leg dynamometer. Oxygen consumption (VO2) and heart rate (HR) data were also collected during cycling at 6 minutes and will be converted to paddle energy. Through this study was found that muscle tension leg rider decreasing with the increasing STA. However, after STA of 66°, the muscle leg tension increasing respecively. The smallest muscle tension leg was 21,4 Kg at 66° STA. At the same position, pedal energy showed 7.148 Kcal which was the smallest result as well. From these study found, that 66° STA also had less muscle tension leg and paddle energy during cycling.

Objective: To analyze the metabolic responses occurring during the practice of exergames in terms of energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adult men and women. Methods: The present study sample was comprised of 102 adults (52 males). Energy expenditure, oxygen consumption rate and metabolic equivalent were assessed with a portable gas analyzer (K4b2). Heart rate was measured with a frequencymeter. All dependent variables were assessed at rest and during the exergame session, which was comprised of four X-box 360 games (volleyball, boxing, athletics, and bowling). Results: Mean age was 34.8 ± 13.4 years. There was a significant increase in resting values during exergame sessions for energy expenditure (male: 467.52%; p < 0.001; female: 393.72%; p < 0.001), oxygen consumption rate (male: 453.97%; p < 0.01; female: 384.74%; p < 0.001), metabolic equivalent (male: 457.40%; p < 0.001; female: 384.74%; p < 0.001) and heart rate (male: 95.10%; p < 0.001; female: 92.26; p < 0.001). When compared to women, men showed significantly higher values for energy expenditure (95% confidence interval = -12.53; -6.67), oxygen consumption rate (95% confidence interval = -4.01; -0.80) and metabolic equivalent (95% confidence interval = -1.18; 0.27) during exergames. Conclusion: A session of exergames is capable of increasing energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adults. Men showed higher values in metabolic parameters when compared to women.

Microbial efficiency in a meromictic reservoirIndices of microbial efficiency (expressed as oxygen consumption and carbon dioxide release) were determined in the water column of the meromictic Piaseczno Reservoir (in an opencast sulphur mine), which is rich in sulphur compounds. Phytoplankton abundances were low in both the mixolimnion (up to 15 m depth) and monimolimnion (below 15 m depth). In summer and winter, carbon dioxide release was 3-fold and 5-fold higher, respectively, in the monimolimnion than in the mixolimnion. Laboratory enrichments of the sulphur substrate of the water resulted in a decrease in oxygen consumption rate of by about 42% in mixolimnion samples, and in the carbon dioxide release rate by about 69% in monimolimnion samples. Water temperature, pH and bivalent ion contents were of major importance in shaping the microbial metabolic efficiency in the mixolimnion, whilst in the monimolimnion these relationships were not evident.
