conferenceObject LACTATE AS MARKER OF METABOLIC SYNDROME IN SEVERE OBESITY Basic science and research in bariatric surgery(2019) VIEIRA, A. Gadducci; CARDIA, L.; OLIVEIRA, F. Costa De; MARIA, J. Greve De; SANTOS, P. Silva Roberto; PAJECKI, D.; AURELIO, M. Santo; CLEVA, R. De- Comparing the Aerobic Fitness of Professional Male Soccer Players and Soccer Referees(2019) SANTOS-SILVA, Paulo R.; GREVE, Julia M. D'Andrea; PEDRINELLI, Andre; ALMEIDA, Adriano M.; OSORIO, Bruna B.; FERREIRA, Marcelo; FERREIRA, CelsoWe looked to compare the aerobic performance between professional soccer referees and players. Fifty male soccer referees and 61 male soccer players were tested on a treadmill. The referees and players possessed 15 +/- 7 years and 7 +/- 3 years of experience in soccer, respectively. Significant differences were observed between the referees and players with regards to: age (34.8 +/- 4.6 years vs 20.8 +/- 2.7 years; P < 0.001, maximum oxygen uptake (54.7 +/- 5.4 mL center dot kg(-1)center dot min(-1) vs 58.8 +/- 4.4 mL center dot kg(-1)center dot min(-1); P < 0.001), and maximal heart rate in peak exercise (184 +/- 11 bpm vs 192 +/- 9 bpm, P < 0.001). Less significant differences also were observed and included; running speed at the maximum oxygen uptake (16.6 +/- 1 km center dot h(-1) vs 16.4 +/- 1.1 km center dot h(-1)), running speed at the ventilatory threshold (213.5 +/- 1.1 km center dot h(-1) vs 13.2 +/- 0.9 km center dot h(-1)), and percentage of maximal oxygen uptake at the ventilatory threshold (285.1% +/- 3.2% vs 84.1% +/- 6.2%). The effect size of most comparative variables between the two groups was small (<0.6). Older elite-level soccer referees are able to reach and maintain aerobic physical fitness levels similar to professional soccer players. Aerobic physical fitness may be a measurable factor for maintaining elite-level soccer licensure rather than age alone.
- Exergy efficiency on incremental stationary bicycle test: A new indicator of exercise performance?(2019) MADY, Carlos Eduardo Keutenedjian; IGARASHI, Tatiane Lie; ALBUQUERQUE, Cyro; SANTOS-SILVA, Paulo Roberto; FERNANDES, Tiago Lazzaretti; HERNANDEZ, Arnaldo JoseThe first and second laws of the thermodynamics were applied to the human body to evaluate the performance of subjects under different training levels. Ten cyclists were evaluated in the stationary bicycle with the indirect calorimetry analysis to obtain the metabolism on an energy and exergy basis. A distinguishing feature of this article is the evaluation of the exergy efficiency of the body with the knowledge of the real performed power and the internal temperature (measured tympanic temperature and calculated esophagus temperature). Regarding the skin temperature, an infrared camera was used to measure different parts of the body. Therefore, the phenomenological behavior of the body was assessed and used as a basis to apply the exergy analysis. Results indicate that the destroyed exergy can be an indicator of performance when compared with maximum oxygen consumption. Nevertheless, more experiments must be carried out to proper state if there is a correlation. Eventually, the exergy efficiency was calculated for all subjects, and its value was around 23 to 28%.
conferenceObject RESTING METABOLIC RATE AND BODY COMPOSITION AFTER 36 MONTHS OF BARIATRIC SURGERY Basic science and research in bariatric surgery(2019) VIEIRA, A. Gadducci; CARDIA, L.; SANTOS, P. Silva Roberto; ANDREA, J. Greve Maria D.; AURELIO, M. Santo; CLEVA, R. De- BONE MINERAL DENSITY AND BODY COMPOSITION IN ELDERLY RUNNERS: SIX-YEAR FOLLOW-UP(2019) ALONSO, Angelica Castilho; ERNANDES, Rita de Cassia; PEREIRA, Regina Helena Marques; BECKER, Ricardo Andre; MACHADO-LIMA, Adriana; SILVA-SANTOS, Paulo Roberto; GREVE, Julia Maria D'Andrea; GARCEZ-LEME, Luiz EugenioObjective: To evaluate bone mineral density (BMD) and body composition over a six-year period in elderly long-distance runners. Methods: We analyzed the medical records of elderly athletes who were long-distance runners, were participants of the IOT-HCFMUSP Orthogeriatric Group, and had their BMD evaluated between 2001 and 2007; of these athletes, 11 were included in the study. Inclusion criteria: athletes should be long-distance runners, should not stop long-distance running during the six-year period, and should have undergone BMD and body composition evaluations. Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry with a Lunar-DPX device. Results: Over the six-year period, body composition remained stable, but there was a significant increase only in the fat percentage (p = 0.003). Conclusion: Long-distance running may maintain BMD but may lead to an increase in the fat percentage in elderly runners.
