The purpose of this study was to determine differences in hamstrings-to-quadriceps (H/Q) peak torque ratios evaluated at different angular velocities between men and women who participate in judo, handball or soccer. A total of 166 athletes, including 58 judokas (26 females and 32 males), 39 handball players (22 females and 17 males), and 69 soccer players(More)
The purpose of this study was to establish the isokinetic profile of shoulder rotator muscles strength in female handball players. Twenty-seven handball players performed concentric and eccentric strength tests of both dominant and non-dominant upper limbs on an isokinetic dynamometer. Internal and external rotator muscles peak torque was assessed at 1.05,(More)
Most resistance training programs use constant rest period lengths between sets and exercises, but some programs use decreasing rest period lengths as training progresses. The aim of this study was to compare the effect on strength and hypertrophy of 8 weeks of resistance training using constant rest intervals (CIs) and decreasing rest intervals (DIs)(More)
The polygenic nature of oral tolerance regulation was elucidated by the method of bidirectional selective breeding of mouse strains for tolerance susceptibility (TS) and resistance (TR) starting from a genetically heterogeneous population achieved by the equilibrated intercrossing of eight inbred mouse strains (A/J, DBA/2J, P/J, SWR/J, SJL/J, CBA/J, BALB/cJ(More)
OBJECTIVE The aim of this study was to evaluate the occurrence of the well-known predisposing factors and signs and symptoms usually associated with either overreaching or overtraining syndrome in physical fitness centers in São Paulo City, Brazil. METHOD A questionnaire consisting of 13 question groups pertaining to either predisposing factors (1-7) or(More)
Strains of mice obtained by genetic selection to extremes of phenotype for susceptibility or resistance to oral tolerance were investigated for possible genetic correlations with acute inflammatory response using different models of inflammation. The results show a strong genetic association.
OBJECTIVE To assess pain, function, quality of life, and muscle strength in patients with shoulder impingement syndrome who participated in muscle strengthening exercises. METHODS A total of 60 patients diagnosed with shoulder impingement syndrome were selected from the clinics of the Federal University of São Paulo and randomly distributed into(More)
OBJECTIVE Blood neurotrophins, such as the brain-derived neurotrophic factor, are considered to be of great importance in mediating the benefits of physical exercise. In this study, the effect of acute strength exercise and the involvement of small versus large muscle mass on the levels of plasma brain-derived neurotrophic factor were evaluated in healthy(More)
OBJECTIVE In this study, we present data from a survey that aimed to assess the physical activity habits of adult Brazilian patients with Posttraumatic Stress Disorder. METHOD Fifty male and female patients with Posttraumatic Stress Disorder participated in this study. The mean age at onset was 37+/-12 years, and the mean time between diagnosis and(More)
