Introduction: The children who eat breakfast, have better cardiorespiratory fitness (CRF),and enhanced ability to learn as compared to others who do not follow this pathway. The aimof this study is to analyse the relations between the eating breakfast, body composition andCRF in school children.Materials and Methods: A cross-sectional study was carried out including 164 girls agedbetween 9 to 11 years. Body composition, CRF and Physical Activity level were assessedduring school time. Frequency of eating breakfast was assessed by a questionnaire andclassified as never, sometimes or always. Fitness was estimated from a 540 m test and theparticipants were classified as having low or high CRF. Body composition was evaluated andchildren were classified as obese or non-obese. PA was estimated from physical activityquestionnaire and the participants were classified as having low or high PA.Results: Frequency of eating breakfast showed that 18% of school children never hadbreakfast, 24% ate sometimes and 58% always ate breakfast. There was no significant relationbetween the frequency of breakfast and anthropometric characteristic. Breakfast consumptionwas not associated with physical activity (p=0.3) and with CRF (p=0.3).Conclusion: fitness level, body composition and PA are not associated with the frequency ofeating breakfast in schoolchildren.

Objective: Inactive lifestyle is related to inefficient cardiorespiratory function. The purpose of the research was to compare the changes in cardiorespiratory performance indicators of inactive youth during a session of passive activity.research methodology:This study is a semi-experimental type and the statistical population of the current study includes inactive students with an average age of 22.07 ± 1.86 years, height 173.71 ± 5.63, weight 11.24 ± 70, body mass 23.32 ± 3.61) of the university Ardabili researcher. Among them, 28 inactive young people were selected as research subjects. Cardio-respiratory fitness of the subjects was measured using the aerobic aerobic test with an intensity of 75 to 85% of the maximum heart rate. Cardio-respiratory indices were measured by a respiratory gas analysis device.Findings: The findings of this research showed that a session of exercise had a significant effect on the values of cardiac and respiratory indicators (heart rate (RR), maximum oxygen ventilation equivalent (EQO2), carbon dioxide ventilation equivalent (EQCO2), tidal volume). (VT) and pulmonary ventilation (VE)) expiratory carbon dioxide partial pressure (PETCO2), expiratory oxygen partial pressure (PETO2)) during different pre-activity stages, aerobic threshold, active rest and anaerobic threshold, there is a significant difference (>0.05) P).Conclusion: According to the obtained results, it seems that an activity session of a helpless type that causes incremental changes in the values of cardio-respiratory and functional heart indices, and can be a suitable criterion for estimating cardio-respiratory fitness in low-income students. be mobility

Introduction: pilates improves spinal condition at an important level of flexibility and strength. the aim of present study was to Investigate the effect of 8 week of Pilates correction exercises on cardiorespiratory fitness and working memory capacity of girle students kyphotic aged 12 to 15 years in Kangavar city in 1400.Metodology: The present study was a quasi-experimental study with a pretest-posttest design. Twenty-five girle students aged 12 to 15 years with kyphosis were purposefully selected. After eliminating the sick and the final drop, the number of samples reached 15. Students' kyphosis angle was measured with a flexible ruler, cardiorespiratory fitness was measured by a shuttle& run test, and working memory capacity was measured by a computer test. K-S test was used to investigate the normal distribution of data and paired t-test was used to evaluate the changes in research variables at the significance level of α = 0.05 using Spss software, version 16.Results: Based on the results of this study, the means of the three variables; There is a significant difference (p≤0.05) in pretest and posttest memory for working memory capacity (p = 0.000), cardiorespiratory readiness (p = 0.000) and kyphosis angle (p = 0.000). It can be argued that Pilates largely avoids high impact, high power output, and heavy muscular and skeletal loading and this improves physiological and cognitive functions.

The purpose of this study was to investigate the rate of obesity and overweight and its relationship with cardiorespiratory fitness in adolescent girls in Aliabad Katoul city. The research method of this research is descriptive and inferential which has been conducted in the field. The population of the study includes 1816 girl students aged 12 to 14 years which 316 students were selected as a sample based on Udinsky table. To estimate the maximum oxygen consumption, a 20-meter shuttle run test was used, Body Mass Index was used to calculate obesity and overweight and subcutaneous fat thickness was used to calculate body fat percentage. Subcutaneous fat thickness was measured at three points in the triceps, calf, and subscapular by a Harponden caliper. Pearson correlation method was used to investigate the relationship between obesity and overweight with cardiorespiratory fitness.Findings showed that the percentage of body fat in adolescent girls’ students increased with age. The findings also showed a decrease in cardiorespiratory fitness of girls’ students with age. According to the results of the study, it is suggested that families, physical education teachers and education officials in schools to include regular activities to improve the respiratory fitness and reduce fatness and overweight of students in their program. In addition, programs increase parents 'awareness about their children's physical condition, solve the problems of overweight and obesity, and improve students' cardiorespiratory fitness.
