    INTRODUCTION: Fragility syndrome, very common in elderly people, consists of a set of signals and symptoms in which is present criteria such as not intentional weight loss (approximately 5%) in a year, reduction in the walking speed, low physical activity levels, subjective exhaustion and muscular strength reduction. The increasing effect of these changes related to age, which include sarcopenia, immunity functional disorder and neuroendocrinous misconduct, increase the vulnerability of the organism to stress, reducing the ability to adapt, compensate or modulate these stimuli. Several intervention proposals have been made to attenuate this process, and resistance exercises (RE) was one of the options studied. OBJECTIVES: To evaluate the effects of RE on the physiopathology of fragility syndrome. MATERIALS AND METHODS: A bibliographic review of the period 2004-2010 was made based on the data of LILACS, MEDLINE and PubMed. Results: Changes in the hormonal and immune systems were observed acting in a systemic way by reverting or minimizing the effects of sarcopenia. CONCLUSION: Resistance exercises should serve as therapy to those elderly who are fragile and do not present any health problems.

    PROGRESSIVE RESISTANCE TRAINING in ELDERLY HIV- POSITIVE PATIENTS: DOES IT WORK?
    (Hospital Clinicas, Univ São Paulo, 2008-10-01) Souza, Paula Maria Loiola de; Jacob-Filho, Wilson; Santarem, Jose Maria; Silva, Alexandre Rodrigues da; Li, Ho Yeh; Burattini, Marcelo Nascimento [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)
    BACKGROUND: Elderly people present alterations in body composition and physical fitness, compromising their quality of life. Chronic diseases, including HIV/AIDS, worsen this situation. Resistance exercises are prescribed to improve fitness and promote healthier and independent aging. Recovery of strength and physical fitness is the goal of exercise in AIDS wasting syndrome.OBJECTIVE: This study describes a case series of HIV-positive elderly patients who participated in a progressive resistance training program and evaluates their body composition, muscular strength, physical fitness and the evolution of CD4(+) and CD8(+) cell counts.METHODS: Subjects were prospectively recruited for nine months. the training program consisted of three sets of 8-12 repetitions of leg press, seated row, lumbar extension and chest press, performed with free weight machines hts, twice/week for one year. Infectious disease physicians followed patients and reported all relevant clinical data. Body composition was assessed by anthropometric measures and dual-energy x-ray absorptiometry before and after the training program.RESULTS: Fourteen patients, aged 62-71 years old, of both genders, without regular physical activity who had an average of nine years of HIV/AIDS history were enrolled. the strengths of major muscle groups increased (74%-122%, p=0.003-0.021) with a corresponding improvement in sit-standing and walking 2.4 m tests (p=0.003). There were no changes in clinical conditions and body composition measures, but triceps and thigh skinfolds were significantly reduced (p=0.037). in addition, there were significant increases in the CD4(+) counts (N=151 cells; p=0.008) and the CD4(+)/CD8(+) ratio (0.63 to 0.81, p=0.009).CONCLUSION: Resistance training increased strength, improved physical fitness, reduced upper and lower limb skinfolds, and were associated with an improvement in the CD4(+) and CD4(+)/CD8(+) counts in HIV positive elderly patients without significant side effects.

    Variação da pressão intraocular após teste submáximo de força no treinamento resistido
    (Conselho Brasileiro de Oftalmologia, 2009-06-01) Conte, Marcelo [UNIFESP]; Scarpi, Marinho Jorge [UNIFESP]; Rossin, Reginaldo Alexandre; Beteli, Hélio Rubens; Lopes, Rodrigo Gustavo; Marcos, Haroldo Leão [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Escola Superior de Educação Física de Jundiaí; ESEFJ
    PURPOSE: To verify the intraocular pressure (IOP) after sub-maximal strength test. METHODS: 145 Physical Education freshmen (22.04 ± 4.17 years old; female and male) from Superior Physical Education School of Jundiaí (ESEFJ) were evaluated in an observacional study. The exclusion criteria were: media opacity and eyeball absence or changes. All subjects agreed to take part in this research and signed up the Informed Consent. IOP was measured by Perkins tonometer: i) pretest: just before the submaximal strength test performance and ii) post-test: immediately after the strength test. The strength test consisted in the one-repetition-maximum-assessment through repetition until fatigue. Resistance training exercises such as bench press, pulley dorsal high, shoulder press, arm curl and leg press 45º were performed. Statistical analyses were obtained through paired Student's t test. RESULTS: Decrease of IOP was observed after the strength test: 13.48 ± 3.32 vs.10.20 ± 3.72 (p<0.001) in the right eye and 13.13 ± 3.96 vs.9.74 ± 3.33 (p<0.001) in the left eye. CONCLUSION: IOP showed relevant decrease after submaximal strength test performance in college students.
