Previous issue date: 2017-02-24 / The effect of physical exercise throughout life on body composition, lipid profile and
oxidative stress is not clearly explained. Thus, the objective of this study was to investigate
and compare body composition, lipid profile and oxidative stress in master athletes of
different modalities, healthy young and sedentary adults. Seventy healthy men were divided
into five groups: young non-athletes (n = 17; 22.7 ?? 7.0 years), adult non-athletes (n = 12;
45.5 ?? 9.9 years), long distance master athletes (n = 18; 53.0 ?? 8.2 years), speed master
athletes (n = 13; 50.0 ?? 8.9 years) and fighters (n = 10; 46.1 ?? 7.0 years). The body
composition was evaluated through skin folds and perimetry. Blood samples were taken at
rest for analysis of lipid peroxidation (TBARS), superoxide dismutase activity, uric acid and
clinical parameters (lipid profile and fasting glycemia) by spectrophotometry. Young nonathletes
and master runners had significantly lower percentage of fat and higher lean mass
compared to adult non-athletes and fighters (p < 0.05). In addition, the lipid profile and lipid
peroxidation did not differ significantly in the studied groups. The groups of young nonathletes
and long-distance master runners showed higher superoxide dismutase activity than
the other groups (p < 0.05), whereas adults non-athletes presented higher concentration (p <
0.05) of acid uric compared to all other groups. The data suggest that healthy young and
master runners present better body composition and lipid profile compared to sedentary
middle-aged individuals and master fighters. In addition, healthy youngsters and longdistance
runners present greater antioxidant defense than the other groups, may be reflect on
the improvement of quality of life during the aging process. / O efeito do exerc??cio f??sico sobre a composi????o corporal, perfil lip??dico e estresse oxidativo
ao longo da vida ainda n??o est??o claramente explicado. Assim, o objetivo deste estudo foi
investigar e comparar a composi????o corporal, perfil lip??dico e estresse oxidativo em atletas
master de diferentes modalidades, jovens saud??veis e adultos sedent??rios. Setenta homens
saud??veis foram divididos em cinco grupos: controle jovem (n = 17; 22,7 ?? 7,0 anos),
controle meia-idade (n = 12; 45,5 ?? 9,9 anos), atletas master de longa dist??ncia (n = 18; 53,0
?? 8,2 anos), atletas master de velocidade (n = 13; 50,0 ?? 8,9 anos) e lutadores (n=10; 46,1 ??
7,0 anos). A composi????o corporal foi avaliada por meio de dobras cut??neas e perimetria.
Amostras de sangue foram realizadas em repouso para an??lises de peroxida????o lip??dica
(TBARS), atividade da super??xido dismutase, ??cido ??rico e par??metros cl??nicos (perfil
lip??dico e glicemia em jejum) por espectrofotometria. Os jovens n??o atletas e os corredores
master apresentaram significativamente menor percentual de gordura e maior massa magra
em compara????o com os adultos n??o atletas e lutadores (p < 0,05). Al??m disso, o perfil lip??dico
e a peroxida????o lip??dica n??o diferiram significativamente nos grupos estudados. Os grupos de
jovens n??o atletas e corredores master de longa dist??ncia mostraram maior atividade da
super??xido dismutase do que os outros grupos (p < 0,05), enquanto que, os adultos n??o atletas
apresentaram maior concentra????o (p < 0,05) de ??cido ??rico em compara????o com todos os
outros grupos. Os dados sugerem que jovens saud??veis e atletas master corredores apresentam
melhor composi????o corporal e perfil lip??dico comparados com os indiv??duos sedent??rios de
meia-idade e lutadores. Ademais, jovens saud??veis e corredores master apresentam maior
defesa antioxidante do que os demais grupos, podendo refletir na melhora da qualidade de
vida durante processo de envelhecimento.
