    Futsal improve body composition and cardiorespiratory fitness in overweight and obese children. A pilot study
    (2018) SANTOS-SILVA, P. R.; GREVE, J. M. D'Andrea; NOVILLO, H. N. E.; HADDAD, S.; SANTOS, C. R. P.; LEME, R. B.; FRANCO, R. R.; COMINATO, L.; ARAúJO, A. T. M.; SANTOS, F. M.; DAMIANI, D.; RICA, R. L.; BOCALINI, D. S.
    Aims: The aim of this study was to verify body composition, cardiorespiratory fitness, and biochemical markers of prepubertal overweight and obese boys to a 16-week futsal training program. Methods: Sixteen boys (age: 7-10 y, body mass index>thanat 95th percentileaccording to Center for Disease Control and Prevention; 35.5±7.4 percent fat) participated to futsal training program. The assessment of body composition was estimated using skinfold thickness, and the following variables were evaluated: total body mass, body mass index, body fat percentage, and lean body mass. Aerobic fitness measurementwas performed by gas exchange analysis in treadmill. In addition, an evaluation of the biochemical profile was conducted: triglycerides, total cholesterol, low density lipoprotein cholesterol, high-density lipoprotein cholesterol, plasma concentrations of glucose, and insulin. The futsal intervention included 60-min sessions performed two times/week. The mean intensity during training was between 57 to 88% of maximal heart rate of the age-predicted. Individual portable heart rate monitor controlled training intensity. Results: Significant increases in total body mass (4%), height (3%), lean body mass (8%), and significant 6%-decrease in body fat percentage was observed. Body mass index remained unchanged. Maximal oxygen uptake was elevated (p<0.018) by 11%. Biochemical markers were not modified after intervention. No association was found between body composition and metabolic variables. The effect size of futsal training on most variables was small (<0.5). Conclusion: Controlled intensity and adherence to this 16-week futsal training program were determinant to enhance body composition, and cardiorespiratory fitness in this group of prepubertal boys. © Universidade Estadual Paulista - UNESP.

    (2017) GADDUCCI, Alexandre Vieira; CLEVA, Roberto de; SANTAREM, Gabriela Correia de Faria; SILVA, Paulo Roberto Santos; GREVE, Julia Maria D'Andrea; SANTO, Marco Aurelio
    OBJECTIVE: The aim of our study was to evaluate associations between maximum voluntary contraction torques of the lower limbs and body composition for subjects with severe obesity. METHODS: Body composition was evaluated by bioelectrical impedance analysis, and maximum voluntary contraction torques of the lower limbs were measured using an isokinetic dynamometer. One hundred thirty-two patients were enrolled (100 females and 32 males). Eighty-seven patients had a body mass index between 40 and 49.9 kg/m(2) (the A group), and 45 patients had a body mass index between 50 and 59.9 kg/m(2) (the B group). RESULTS: Absolute extension and flexion torques had weak associations with fat-free mass but a moderate association with absolute extension torque and fat-free mass of the lower limbs. There were no significant differences between the A and B groups with respect to absolute extension and flexion torques. For the A group, absolute extension and flexion torques were moderately associated with fat-free mass and with fat-free mass of the lower limbs. For the B group, there were only moderate associations between absolute extension and flexion torques with fat-free mass of the lower limbs. CONCLUSIONS: Our findings demonstrate that both groups exhibited similar absolute torque values. There were weak to moderate associations between absolute extension and flexion torques and fat-free mass but a moderate association with fat-free mass of the lower limbs. Individuals with severe obesity should strive for greater absolute torques, fat-free mass and especially fat-free mass of the lower limbs to prevent functional limitations and physical incapacity.

    Association between muscle strength and the cardiopulmonary status of individuals living with HIV/AIDS
    (2013) RASO, Vagner; SHEPHARD, Roy J.; CASSEB, Jorge; DUARTE, Alberto Jose da Silva; SILVA, Paulo Roberto Santos; GREVE, Julia Maria D'Andrea
    OBJECTIVE: The purpose of this study was to compare aerobic function [ anaerobic threshold (%(V) over dotO(2)-AT), respiratory compensation point (%(V) over dotO(2)-RCP) and peak oxygen uptake ((V) over dotO(2peak))] between physically active patients with HIV/AIDS and matched controls and to examine associations between disease status, poor muscle strength, depression (as estimated by the profile of mood states questionnaire) and the aerobic performance of patients. METHODS: Progressive treadmill test data for %(V) over dotO(2)-AT (V-slope method), RCP and ((V) over dotO(2peak)) were compared between 39 male patients with HIV/AIDS (age 40.6 +/- 1.4 years) and 28 male controls (age 44.4 +/- 2.1 years) drawn from the same community and matched for habitual physical activity. Within-patient data were also examined in relation to CD4(+) counts (nadir and current data) and peak isokinetic knee torque. RESULTS: AT, RCP and ((V) over dotO(2peak)) values were generally similar for patients and controls. Within the patient sample, binary classification suggested that AT, RCP and ((V) over dotO(2peak)) values were not associated with either the nadir or current CD4(+) count, but treadmill test variables were positively associated with peak isokinetic knee torque. CONCLUSION: The aerobic performance of physically active patients with HIV/AIDS is generally well conserved. Nevertheless, poor muscle strength is observed in some HIV/AIDS patients, which is associated with lower anaerobic power and ((V) over dotO(2peak)), suggesting the possibility of enhancing the aerobic performance of patients with weak muscles through appropriate muscle-strengthening activities.

    Contemporary reflection on the educational levels of high-performance soccer players in Brazil
    (2023) SANTOS-SILVA, Paulo Roberto; GREVE, Julia Maria D'Andrea; SILVA, Renato Luis da; SPINOLA, Marcelo Mesquita
    Objective: As the soccer culture in Brazil is more popular than schooling, this study reflected on the formal education levels of soccer (football) players through descriptive and quantitative analyses. Methods: We evaluated 179 national soccer players playing various positions on different teams across six seasons (2012, 2013, 2014, 2015, 2016, and 2022). Data were collected using a questionnaire comprising the following variables: age, position in the pitch, age of professionalization, and education (years of study). The data were distributed according to the pitch position. Results: The mean age, length of professional career, and professionalization age were 23 +/- 6 years, 7 +/- 5 years, and 17 +/- 2 years, respectively. In terms of education, 121 athletes (67%) completed high school, equivalent to 11 years of study. Only 5.5% completed higher education, with defensive players (goalkeepers and defenders) being the most educated at 37% (66/179). According to 2017 figures from the Pesquisa Nacional por Amostra de Domicilios Continua of the Federal Government of Brazil, the schooling rate is 31.7%, wherein 46.1% of Brazilians aged 25 years or over have completed education. In this study of 179 athletes, 67% had completed high school. Thus, players outrank the Brazilian population in terms of achieving a high school education. There were marked disparities in the relative proportions of goalkeepers (85%), defensive players (68%), midfielders (63%), and forward players (64%) in terms of their education. Conclusion: Our survey revealed that attending higher education remains a distant reality in Brazil.

    TRUNK BODY MASS INDEX: A NEW REFERENCE FOR THE ASSESSMENT OF BODY MASS DISTRIBUTION
    (2018) TAKESIAN, Mariane; SANTO, Marco Aurelio; GADDUCCI, Alexandre Vieira; SANTAREM, Gabriela Correia de Faria; GREVE, Julia; SILVA, Paulo Roberto; CLEVA, Roberto de
    Background: Body mass index (BMI) has some limitations for nutritional diagnosis since it does not represent an accurate measure of body fat and it is unable to identify predominant fat distribution. Aim: To develop a BMI based on the ratio of trunk mass and height. Methods: Fifty-seven patients in preoperative evaluation to bariatric surgery were evaluated. The preoperative anthropometric evaluation assessed weight, height and BMI. The body composition was evaluated by bioimpedance, obtaining the trunk fat free mass and fat mass, and trunk height. Trunk BMI (tBMI) was calculated by the sum of the measurements of the trunk fat free mass (tFFM) and trunk fat mass (tFM) in kg, divided by the trunk height squared (m(2)). The calculation of the trunk fat BMI (tfBMI) was calculated by tFM, in kg, divided by the trunk height squared (m(2)). For the correction and adjustment of the tBMI and tfBMI, it was calculated the relation between trunk extension and height, multiplying by the obtained indexes. Results: The mean data was: weight 125.3 +/- 19.5 kg, height 1.63 +/- 0.1 m, BMI was 47 +/- 5 kg/m(2) and trunk height was 0.52 +/- 0,1 m, tFFM was 29.05 +/- 4,8 kg, tFM was 27.2 +/- 3.7 kg, trunk mass index was 66.6 +/- 10.3 kg/m(2), and trunk fat was 32.3 +/- 5.8 kg/m(2). In 93% of the patients there was an increase in obesity class using the tBMI. In patients with grade III obesity the tBMI reclassified to super obesity in 72% of patients and to super-super obesity in 24% of the patients. Conclusion: The trunk BMI is simple and allows a new reference for the evaluation of the body mass distribution, and therefore a new reclassification of the obesity class, evidencing the severity of obesity in a more objectively way.

    Blood lactate and oxygen consumption in soccer players: comparison between different positions on the field
    (2017) SANTOS-SILVA, Paulo Roberto; PEDRINELLI, André; GREVE, Júlia Maria D'Andrea
    OBJECTIVE: We hypothesize that in players with better aerobic fitness, lactate production was not inhibited after high-intensity exercise, regardless of the footballer's position on the field. METHOD: Sixty professional male soccer players performed cardiopulmonary exercise tests on an ergometric treadmill; respiratory gas exchanges were monitored throughout and blood lactate levels at peak effort was measured, using a portable device. The heart rate response was determined by computerized EKG. Training sessions took place over an average of ten hours per week, and the players had 6.8 years of experience in competitive soccer; they were tested a third of way into the season. The positions tested were (centerback, fullback, midfielder and striker). RESULTS: The following results (mean ± std. dev.) were obtained: (1) peak oxygen consumption of 58.8 ± 4.5 ml.kg-1.min.-1; (2), blood peak lactate of 12.3 ± 1.6 mmol.L-1; (3) maximum heart rate of 193 ± 3.3 beats. min-1; (4); oxygen consumption at the second ventilatory threshold of 49.6 ± 5.0 mL. kg-1.min-1; (5); running speed at the second ventilatory threshold of 13.3 ± 0.8 km.h-1; (6) percentage of oxygen consumption in the second ventilatory threshold of 84 ± 6%. There was no correlation between maximum aerobic level vs. peak lactate concentration (r = -0,031; p = 0.812), nor between submaximal aerobic level vs. peak lactate concentration (r = -0.146; p = 0.335) in the positions tested. CONCLUSION: Better or worse aerobic profiles according to game positions in soccer players do not influence peak lactate levels following high-intensity exercise, and confirms the study hypothesis.

    (2015) SANTAREM, G. Correia de Faria; CLEVA, R. de; SANTO, Marco Aurelio; BERNHARD, Biaseto; GADDUCCI, Alexandre Vieira; GREVE, Julia Maria D'Andrea; SILVA, Paulo Roberto Santos
    Background Obesity is associated with mobility reduction due to mechanical factors and excessive body fat. The six-minute walk test (6MWT) has been used to assess functional capacity in severe obesity. Objective To determine the association of BMI, total and segmental body composition with distance walked (6MWD) during the six-minute walk test (6MWT) according to gender and obesity grade. Setting University of Sao Paulo Medical School, Brazil; Public Practice. Methods Functional capacity was assessed by 6MWD and body composition (%) by bioelectrical impedance analysis in 90 patients. Results The mean 6MWD was 514.9 +/- 50.3 m for both genders. The male group (M: 545.2 +/- 46.9 m) showed a 6MWD higher (p = 0.002) than the female group (F: 505.6 +/- 47.9 m). The morbid obese group (MO: 524.7 +/- 44.0 m) also showed a 6MWD higher (p = 0.014) than the super obese group (SO: 494.2 +/- 57.0 m). There was a positive relationship between 6MWD and fat free mass (FFM), FFM of upper limps (FFM_UL), trunk (FFM_TR) and lower limbs (FFM_LL). Female group presented a positive relationship between 6MWD and FFM, FFM_UL and FFM_LL and male group presented a positive relationship between 6MWD and FFM_TR. In morbid obese group there was a positive relationship between 6MWD with FFM, FFM_UL, FFM_TR and FFM_LL. The super obese group presented a positive relationship between 6MWD with FFM, FFM_TR and FFM_LL. Conclusions Total and segmental FFM is associated with a better walking capacity than BMI.
