“…Besides aiming to reduce body weight, particularly central fat weight, the main goal of the participants was to improve appearance, and to look good, healthy and strong. In that sense, their goals were in line with the recommendations of the stateof-the-art, which are to combine aerobic and progressive resistance training (O'Brien et al 2004, Robinson et al 2007, Hand et al 2009, Lazzarotto et al 2010, O'Brien et al 2010, Souza et al 2011, Yahiaoui et al 2011). …”

This study aimed to analyse the physical health effects of a community based 10-week physical activity programme with people living with HIV. It was developed, implemented and evaluated in a disadvantaged community in South Africa. A pre-post research design was chosen. Major recruitment and adherence challenges resulted in a small sample. Among the 23 participants who took part in both baseline and final testing, compliant participants (n = 12) were compared to non-compliant participants (n = 11). Immunological (CD4, viral load), anthropometric (height, weight, skinfolds and waist to hip ratio), muscular strength (h1RM) and cardiopulmonary fitness (time on treadmill) parameters were measured. The compliant and non-compliant groups were not different at baseline. Muscular strength was the parameter most influenced by compliance with the physical activity programme (F = 4.516, p = 0.047). Weight loss and improvement in cardiopulmonary fitness were restricted by the duration of the programme, compliance and influencing factors (e.g. nutrition, medication). The increase in strength is significant and meaningful in the context, as the participants' goals were to look healthy and strong to avoid HIV related stigma. The improvements in appearance were a motivational factor, especially since the changes were made visible in a short time. Practical implications for health promotion are described. More research contextualised in disadvantaged settings is needed.

HIV behavioural interventions targeted towards older adults: a systematic review

2014

BackgroundThe increasing number of people living with HIV aged 50 years and older has been recognised around the world yet non-pharmacologic HIV behavioural and cognitive interventions specifically targeted to older adults are limited. Evidence is needed to guide the response to this affected group.MethodsWe conducted a systematic review of the available published literature in MEDLINE, Embase and the Education Resources Information Center. A search strategy was defined with high sensitivity but low specificity to identify behavioural interventions with outcomes in the areas of treatment adherence, HIV testing uptake, increased HIV knowledge and uptake of prevention measures. Data from relevant articles were extracted into excel.ResultsTwelve articles were identified all of which originated from the Americas. Eight of the interventions were conducted among older adults living with HIV and four for HIV-negative older adults. Five studies included control groups. Of the included studies, four focused on general knowledge of HIV, three emphasised mental health and coping, two focused on reduced sexual risk behaviour, two on physical status and one on referral for care. Only four of the studies were randomised controlled trials and seven – including all of the studies among HIV-negative older adults – did not include controls at all. A few of the studies conducted statistical testing on small samples of 16 or 11 older adults making inference based on the results difficult. The most relevant study demonstrated that using telephone-based interventions can reduce risky sexual behaviour among older adults with control reporting 3.24 times (95% CI 1.79-5.85) as many occasions of unprotected sex at follow-up as participants. Overall however, few of the articles are sufficiently rigorous to suggest broad replication or to be considered representative and applicable in other settings.ConclusionsMore evidence is needed on what interventions work among older adults to support prevention, adherence and testing. More methodological rigourised needed in the studies targeting older adults. Specifically, including control groups in all studies is needed as well as sufficient sample size to allow for statistical testing. Addition of specific bio-marker or validated behavioural or cognitive outcomes would also strengthen the studies.

“…Estes resultados são consistentes com os estudos de Lindegaard et al (2008), Sakkas et al (2009), Souza et al (2008, Souza et al (2011). O aumento da força muscular é extremamente importante para o metabolismo corporal de HIV soropositivos, uma vez que é diretamente associado ao aumento da taxa metabólica basal e do catabolismo de lipídios na região abdominal (ORMSBEE et al, 2007).…”

“…Ademais, revisão de literatura tem sugerido limitações como ausência de grupocontrole (ROBINSON et al, 2007;SOUZA et al, 2008), amostras pequenas (RØGE et al, 2002;ROBINSON et al, 2007;SOUZA et al, 2008) e reduzido período de intervenção (LINDEGAARD et al, 2008;SAKKAS et al, 2009). O TR, por sua vez, pode ser usado para evitar a perda da massa magra e a perda funcional do músculo, uma vez que um dos efeitos crônicos clássicos do TR, importante para esta população, é o aumento da força (MENDES et al, 2011), oriundo tanto pelo aumento da área transversa muscular (DOLAN et al, 2006), quanto pela melhora da eficiência muscular (DOLAN et al, 2006;MENDES et al, 2011;SOUZA et al, 2011). Diante do exposto, o presente estudo tem por objetivo investigar o efeito de 24 semanas de TR em medidas antropométricas, força e hipertrofia muscular de pacientes soropositivos com avaliação dos hábitos alimentares e a prescrição dietética realizada por nutricionista.…”

Resumo: O presente estudo investigou o efeito de 24 semanas de treinamento resistido (TR) sobre a força e hipertrofia muscular de pacientes HIV-soropositivos. Participaram deste estudo 45 voluntários submetidos à terapia antirretroviral fortemente ativa (HAART), destes, 23 realizaram 3 sessões semanais, com 10 repetições a 80% 1RM. O teste de 1RM foi realizado de acordo com a metodologia proposta por Kraemer e Fry (1995), para estimativa da hipertrofia muscular adotou-se as equações de Frisancho (1984). Em comparação aos valores, o TR melhorou a força de 1RM nos exercícios de agachamento em 49% (21,0±4,9 vs. 31,2±5,1; P=0,001), supino reto em 13% (34,3±8,1 vs. 39,8±9,4; P=0,04), cadeira extensora em 34,1% (26,3±7,1 vs. 37,1±6,6; P=0,01), tríceps em 51% (22,9±4,0 vs. 38,3±4,9; P=0,001), pulley costas em 31,5% (31,7±3,9 vs. 41,7±4,4; P=0,01), cadeira flexora em 37,2% (18,9±3,4 vs. 27,3±3,2; P=0,01) e rosca bíceps em 60% (27,9±6,9 vs. 40,4±4,5; P=0,001). Não foram observadas diferenças (P<0,05) entre os valores basais e finais para o grupo controle. Observou-se aumento significativo (P<0,05) na área muscular do braço isenta de massa óssea, no grupo TR (52,8±14,5 cm 2 ) em relação ao controle (39,5±12,4 cm 2 ). Ademais, o TR resultou em significativa (P<0,05) redução da glicemia sanguínea de jejum (96,5±18,3 vs. 90,5±12,6), pressão arterial sistólica (126,3±14,3 vs. 120,0±10,0) e circunferência de cintura (83,0±12,5 vs. 80,6±10,2). Conclui-se que seis meses de TR resultaram em melhora na força e hipertrofia, ademais, o treinamento aplicado contribuiu para a regulação das variáveis metabólicas dos pacientes. Uma vez que a HAART é inevitável ao HIV-soropositivo, recomenda-se que o exercício físico seja realizado no intuito de dirimir os efeitos colaterais advindos desta terapia.

Impact of resistance training on strength and muscle hypertrophy in HIV-seropositiveAbstract: The aim of this study was to investigate the effect of 24 weeks of resistance training (RT) on the strength and muscle hypertrophy in patients with HIV-seropositive. Participated in the study 45 subjects undergoing highly active antiretroviral therapy (HAART). They were divided into two groups: control (n=22) and RT (n=23). The RT group realized three sessions, with 10 repetitions at 80% of 1MR. The MR tests were performed pre and post 24 weeks according to Kraemer and Fry (1995) and the equations proposed by Frisancho (1984) were adopted to estimate bone-free upper arm muscle area. Compared to baseline, the RT improved the strength of 1MR in the squat exercise at 49% (21.0±4.9 vs. 31.2±5.1; P=0.001), bench press by 13% (34.3±8.1 vs. 39.8±9.4, P=0.04), leg extension in 34.1% (26.3±7.1 vs. 37.1±6.6, P=0.01), triceps in 51% (22.9±4.0 vs. 38.3±4.9, P=0.001), pulley in 31.5% (31.7±3.9 vs. 41.7±4.4, P=0.01), leg curl in 37.2% (18.9±3.4 vs. 27.3±3.2, P=0.01) and biceps in 60% (27.9±6.9 vs. 40.4±4.5, P=0.001); there were...
