“…Gender difference in body composition was implicated as a main factor for gender difference in maximal oxygen consumption. Expressing VO-2max relative to fat free mass or lean body mass did not eliminate these differences, although they were slightly reduced [29]. In an investigation of the relationship between cardiorespiratory fitness (CRF) and some anthropometric factors in children and adolescent in Bosnia and Herzegovina, it was found that CRF was associated with lower waist circumferences (WC) and higher waist to height ratio.…”

AbstractAim: The aim of this study was to determine and analyse the relations between anthropometric parameters, red blood cells’ (RBC) variables and cardio-physiological parameters in healthy and physically active children and adolescents.Material and Methods: In this study 625 subjects, (410 males and 215 females; age span 8 to 18 years) underwent body composition analysis (Matiegka method), blood analysis and ergometry testing (Bruce protocol).Results: In both groups, body height and weight were positively correlated with RBC variables. In female group almost all correlations between RBC variables and body components were insignificant. In boys all absolute body mass components showed positive correlations with RBC variables with notice that body fat mass had lowest correlation coefficient. Body fat percent (BF %) did not show any correlation with RBC variables in both gender groups. In boys BF % had moderate negative correlation with aerobic performance: exercise time (ET) and VO2max (rs = -0.41 and rs = -0.39). Lean body components showed weak positive correlations with ET and VO2max. RBC count did not show significant correlation with any cardio-physiological parameter in both groups. Haematocrit and haemoglobin showed weak positive correlations with VO2 max and general endurance (exercise time). In girls all correlations between cardio-physiological and RBC variables were insignificant. The relationship between all body components and all cardio-physiological variables in girls were statistically insignificant.Conclusions: Our findings revealed that there are some expected positive correlations between lean body mass components, aerobic performance and RBC variables in boys, while in girls such relations were not noticed.

“…Therefore, the authors apply COVID-19 exercise as a solution to overcome this problem, namely by increasing the mental toughness and aerobic capacity of adults. The author tries to conduct a review based on gender differences to clarify the understanding of the benefits provided because there are differences in abilities between men and women [22][23][24].…”

The COVID-19 outbreak has made changes in the process of social life, including sports activities. Individuals become limited in carrying out activities so that they often choose not to do physical activities. Individual inactivity causes various internal problems, such as fatigue and mental problems. The author creates an exercise that aims to overcome this problem by manipulating the intensity in it, namely COVID-19 gymnastics. This study aims to test the COVID-19 exercise with low and high intensity on increasing aerobic capacity and mental toughness in different sex of adult people. The experimental method for 6 weeks was carried out in this study to 150 subjects (65 men and 85 women) by professional gymnastics experts. The Walk Test and Mental Toughness Inventory were used as research instruments which were given twice before and after being given treatment. MANOVA test with SPSS version 24 was used as the data analysis of this study. The results showed that COVID-19 exercise with high and low intensity affected increasing aerobic capacity and mental toughness in adult men and women. However, there is a difference in the effect of highintensity and low-intensity COVID-19 exercise on increasing aerobic capacity and mental toughness in adult men and women. This study concluded that COVID-19 exercise with high intensity and low intensity both had a positive effect on increasing aerobic capacity and mental toughness in adult men and women. However, low-intensity COVID-19 exercise has a better effect than high-intensity because it is considered safer for adults. The author suggests doing fun sports activities such as COVID-19 gymnastics to stay healthy physiologically and psychologically, especially during this pandemic.

“…Studies of the differences between adolescent males and females, (mean age 15.01.1vs 14.91.1 years; body fat percent: 15.5% vs 20.2%) indicated the following cardio physiologic parameters: HRR (bpm)=73.7 vs 78.1; VO2max (ml/kg/min)=51.2 vs 48.4 (Saghiv et al, 2017). Contrary to adults, findings in pre-pubescent children demonstrate that the exclusive restraining factor of VO2max that distinguished boys from girls could be a poorer systolic volume (SVmax), and this gender difference vanished when normalized for LBM.…”

“…It is not completely explained how gender affects overall cardiac dimensions and amount of VO2max in boys and girls. It is not clear whether heart size differences between adolescent girls and adolescent boys are affected by general body dimensions (especially of lean body mass), or whether there are other essential functional differences (Saghiv et al, 2017).…”

“…Maximal oxygen uptake (VO2max) is measured, arterial oxygen content and oxygen extraction and in addition to the functionality of many organic systems and health and fitness status, it depends on age and gender (da Cunha, Farinatti, & Midgley, 2011). In adolescents as in adults, gender differences in VO2max have been accredited to several external and internal factors such as body composition, blood hemoglobin concentration and cardiac size and function, and amount of PA (Saghiv, Sherve, Sira, Saghiv, & Goldhammer, 2017). Changes that occur in body dimensions, body composition, hematological and cardio-physiological parameters should be quantitatively determined as they indicate good growth and development in a young person's body.…”

Physical activity (PA) is stimulatory physiologic stress for the human body and regular PA induces significant changes in many physiological, biochemical and anthropological parameters. The aim of this study is to determine the values and the differences among the cardio-physiological, hematological and anthropological parameters for different age and gender subgroups in healthy physically active children and an adolescent population. An anthropometric evaluation (Matiegka protocol), hematological analysis i.e., red blood cells count (RBC), hemoglobin level, hematocrit, and ergometrical testing (Brus protocol) were made. Regarding mass and height until the age of 12 (U12), girls were heavier and taller than boys. The mean values for relative muscle mass in all the groups of boys and girls of different ages are in the optimal range (>50%) and indicate well developed muscle mass. There are no differences between the same age subgroups for this anthropometric parameter between the boys and girls. All the subgroups of girls of different ages showed higher body fat percent than their male siblings. Among the girls, RBC variables did not show a difference in the age subgroups. Regarding gender, all RBC variables were significantly higher among the male groups, except the U12. Cardio-physiological parameters of heart frequency at rest, exercise time duration and maximal oxygen consumption (VO2max), were significantly higher among the boys. In all age-based male subgroups VO2max was higher among the older boys. Conclusion: This study has shown age related changes in anthropological, hematological and ergometrical parameters in a male and female young active population. The girls showed significantly lower levels of cardio-physiological fitness which can be contributed either to gender and lower volume of PA.
