Comparative study on the validity of monitoring test indexes of healthy fitness cardiopulmonary track and field sensor

With the continuous increase in social pressure and people’s higher urgency for physical health, the concept of healthy physical fitness has become more and more important and prominent. However, the research and standards for the validity of the health fitness monitoring test indicators have not been determined. In order to compare the validity of the health fitness test indicators, we adopt the cardiopulmonary track and field sensor technology to monitor the health fitness cardiopulmonary track and field sensor. A comparative study on the validity of test indicators, mainly to test the rationality of the cardiopulmonary endurance evaluation indicators of healthy physical fitness, and to carry out a new design of the concept of healthy physical fitness in track and field teaching, so that it is more inclined to improve the healthy physical fitness of athletes fitness. Research data shows that the average absolute value of the athlete’s maximum oxygen consumption is 2.51 L/min, the highest value is 3.96 L/min, and the lowest is 2.03 L/min. The average value of the absolute maximum oxygen consumption of girls is 1.79 L/min, the highest value is 2.89 L/min, and the minimum is 1.51 L/min. From these data, we can know that compared with traditional cardiopulmonary monitoring methods, the sensor monitoring studied in this paper has higher accuracy and wider application range. The peak cardiopulmonary power of athletes’ cardiopulmonary function detection using this method is closer to the actual value, while for the peak cardiopulmonary power detected by traditional methods, there is a big difference between the power and the actual value. For different athletes, the advantages of the algorithm in this paper are more obvious, indicating that the method in this paper has a higher detection accuracy for the cardiopulmonary function test of athletes during aerobic training.

The role of anthropometrics in predicting the maximum oxygen consumption in emergency medicine students

BACKGROUND: Maximum oxygen consumption (VO2 max) is an important measure of cardiovascular capacity to deliver oxygen to the working muscle at maximal exercise. Anthropometrics is one of the factors that contribute to the maximum oxygen consumption. OBJECTIVE: This study aimed to predict the maximum oxygen consumption based on anthropometrics in the emergency medicine students. METHODS: This cross-sectional study was conducted on the emergency medicine students (n = 56) at Qazvin University of Medical Sciences. Before the data collection, participants completed the consent form and Physical Activity Readiness Questionnaire (PAR-Q). Then, the maximum oxygen consumption and anthropometrics (dimensions and compositions) were measured using Gerkin treadmill test and using tape, anthropometer device and digital caliper respectively. Data were analyzed using Pearson correlation, one-way analysis of variance and multivariate linear regression. RESULTS: The mean of maximum oxygen consumption was 4.11 lit/min in the emergency medicine students. There was a significant relationship between maximum oxygen consumption and anthropometrics (body dimensions and compositions including body fat, waist to hip circumference, and BMI) (p < 0.05). Also, the leg length, the body fat, and the BMI predicted 72% of oxygen consumption. The leg length and BMI had an important role in predicting the maximum oxygen consumption. CONCLUSIONS: The body dimensions and compositions should be taken into consideration to select students and match their capabilities with required energy for the job.

External respiration and gas exchange in conditions of maximum load at different levels of the body's aerobic capacity

The study of the characteristics of the reactions of the links of external respiration and gas exchange at various stages of performing a step-increasing load and at maximum load with various aerobic capabilities of the body was carried out. The data obtained indicate that the level of aerobic capabilities of the body determines the characteristics of the reactions of the links of external respiration and gas exchange at various stages of performing a step-increasing load and at maximum load. Key words: functional reserves of organism, gas transportation system, maximum oxygen consumption, aerobic capacity of organism, gas exchange.

Combined Aerobic and Resistance Training Performed under Conditions of Normobaric Hypoxia and Normoxia Has the Same Impact on Metabolic Control in Men with Type 1 Diabetes

(1) Background: The aim was to assess whether combined aerobic and resistance training performed under hypoxic and normoxic conditions had an impact on diabetes control, VO2max (maximum oxygen consumption), and echocardiological and anthropometric parameters in men with long-term type 1 diabetes. (2) Methods: Sixteen male participants (mean age: 37 years, mean HbA1c (glycated hemoglobin): 7.0%) were randomly assigned to two groups: training in normoxic conditions or training in conditions of altitude hypoxia. All subjects participated in 60 min combined aerobic and resistance training sessions twice a week for 6 weeks. At baseline and in the 6th week, echocardiography, incremental exercise test, and anthropometric and diabetes control parameters were assessed. (3) Results: After 6 weeks, there was no significant change in HbA1c value in any group. We noted a more stable glycemia profile during training in the hypoxia group (p > 0.05). Patients in the hypoxia group required less carbohydrates during training than in the normoxia group. A comparable increase in VO2max was observed in both groups (p > 0.05). There were no significant differences in cardiological and anthropometric parameters. (4) Conclusions: Combined aerobic and resistance training improved VO2max after 6 weeks regardless of the conditions of the experiments. This exercise is safe in terms of glycemic control in patients with well-controlled diabetes.

Assessment of professional Argentine football players using the UNCa test

Objective: To evaluate the maximum oxygen consumption (VO2max) and the Maximum Aerobic Speed (MAS) with direct and portable measurement in field, in professional soccer players using the UNCa test. Material and method: 9 professional soccer players (age: 26.8±5.12 years, mass: 78.7±5.8 kg, height: 177.3±5.8 cm), belonging to the first and promotion categories of AFA soccer league, were measured in the field with the UNCa test using direct gas measurement. A subsample of 3 players was also measured on treadmill. On treadmill and in the field, the same Medgraphics® VO2000 gas analyzer was used. Results: In the field, a VO2max of 52.18±5.86 ml/kg/min, and a MAS of 14.8±1.3 km/h were found. Also, a correlation between VO2max and MAS of r = 0.75, and between MAS and the final speed reached (FSR) r=0.91. In the subsample, no differences were found between treadmill and field in VO2max; 46.6±1.4 ml/kg/min and 48.1±2.2 ml/kg/min (p <0.001) respectively. Differences between MAS are shown; 17.0±0.0 km/h for the treadmill and 13.7±1.5 km/h for the field (p <0.001) replicating the protocol. Conclusion: If professional players of the Argentine Football Association (AFA) were measured directly and in the field, applying the UNCa test for the first time. The VO2max and MAS values were slightly lower than those published in the bibliography

Selection Criteria for Heart Transplantation in Patients with End-Stage Heart Failure

Today, heart transplantation remains the gold standard of treatment for patients with end-stage heart failure (HF). As the number of donors is limited and the risk of intervention is quite high, the key to achieving optimal outcomes and reducing the incidence of complications is the proper selection of patients who meet clearly defined criteria for inclusion in the waiting list for heart transplantation. This review presents the latest knowledge on indications and contraindications for inclusion recipients in the waiting list for heart transplantation, including the latest clinical guidelines of The International Society for Heart and Lung Transplantation (ISHLT) published in 2016. Thus, the absolute indications are dependence on intravenous inotropic and mechanical circulatory support; inoperable heart diseases or a history of volume reducing operations; refractory angina or life-threatening refractory arrhythmias despite maximal drug therapy and/or surgical correction; reduction of maximum oxygen consumption up to <12-14 ml/kg/min when performing the maximum cardiopulmonary exercise test. While including patients in the waiting list for heart transplantation, it should be noted that the low left ventricular ejection fraction <30%, a history of documented NYHA class III-IV HF, low maximum oxygen consumption as the only criterion of terminal HF and poor prognosis for annual survival in HF calculated on prognostic scales are not sufficient indications. Absolute contraindications include a systemic disease with a life expectancy of less than 2 years and irreversible pulmonary hypertension. The current procedure for the distribution of recipients by urgency status for heart transplantation is presented according to the updated recommendations of the United Network for Organ Sharing (UNOS) published in 2018 which consists of 6 degrees, compared with the 1999 edition which contained 3 degrees.

Beneficios de la actividad física durante un lapso de 16 semanas en pacientes con Enfermedad de Parkinson de la fundación “FUNDAPE”, Marzo–Septiembre 2019

BACKGROUND: Parkinson's disease (PD) is neurodegenerative, explained by the loss of dopaminergic neurons of the substantia nigra, affecting most commonly people over 60 years of age. The aim of this study was to analyze the benefits in both motor and non-motor symptoms, found after a 16-week pro- gram of physical activity in people with this disease who belong to the Parkinson Foundation of Ecuador (FUNDAPE). METHODS: This is a quasi-experimental interventional study, with a sample of 17 patients with Parkin- son’s disease diagnosis that went through a 16 week program of aerobic exercise, to analyze its impact on maximum oxygen consumption, motor skills, balance, cognition, body composition, and presence of depression. For the analysis, Wilconson “t-test” was applied. Confidence interval was 95%, 5% error. RESULTS: The maximum oxygen consumption improved 29.86%. The percentage of fat mass decreased 10.78%. The muscle weight percentage increased 4.58%. Regarding the different evaluated tests, the mean score for UPRDS improved 8.29%; the mean score for Berg Scale test improved 6.25%; regarding Ye- savage Geriatric Depression Scale, the percentage of patients with probable depression decreased from 42.86% to 7.14% in the group with PD of ≤5 years of evolution, and from 66.67% to 33.33% in the group with PD for than 5 years; regarding the Folstein Minimental State of Mind test, we found no benefits. CONCLUSION: This study showed that there are statistically significant benefits resulting from the appli- cation of a 16 week aerobic exercise program in patients with Parkinson’s disease, related to the motor and non-motor symptoms of the disease, body composition, and maximum oxygen consumption. No significant benefits were found in relation to the cognitive impairment associated with the disease. The benefits were greater in patients younger than 60 years of age, and were also greater in patients with less than 5 years of evolution of the disease.

Response of Aerobic Capacity to Low-Level Laser Therapy in Burned Patients

Background Severe burns lead to decreased pulmonary function and impaired aerobic capacity for long periods post-injury. Low-level laser therapy is a modality utilized to improve aerobic capacity, enhance exercise performance and increase time until fatigue when utilized before aerobic exercises. Purpose This work aims to determine the impacts of pre-exercise low-level laser therapy on aerobic capacity in burn cases. Participants and Methods Sixty adults burned cases of both sexes, aged from 25 to 40 years, with second-degree healed thermal burns, and the total burned body surface area ranged from 20 to 40% participated in this study after complete wound healing. They were randomly categorized into two groups of equal numbers. The study group received low-level laser therapy before aerobic exercises, three sessions/week for 12 weeks, while the control group performed aerobic exercises three times weekly for 12 weeks. All cases received the routine physical treatment program. Aerobic capacity was assessed for both groups by measuring maximum oxygen consumption and time to exhaustion at baseline and twelve weeks following interventions. Findings There was a statistically significant rise in the mean values of maximum oxygen usage and time to fatigue after 12 weeks of treatment in both groups. However, after comparison, the improvements in the study group were statistically significant than those in the control group with (p &lt; 0.01), (p &lt; 0.05) respectively. Conclusion Low-level laser therapy has a beneficial therapeutic impact on promoting aerobic capacity, improving maximum oxygen consumption, and increasing treadmill time in burned cases when preceding aerobic exercises.
