Detraining period of the PILATES method on functional capacity of elderly women with type 2 diabetes: A randomized clinical trial.

INTRODUCTION: The aim of this study was to verify the effects of a 4-week detraining period on the functional capacity of elderly women with type-2 diabetes (T2D) after 12 weeks of a PILATES training program. METHODS: Twenty-two individuals with T2D were randomly allocated into two groups: CONTROL (n = 11; 67.5 ± 6.3 years; 154.7 ± 6.1 cm; 73.5 ± 6.1 kg; calorie intake: 1487.5 ± 360.6 kcal/day) and PILATES (n = 11; 65.5 ± 5.5 years; 155.0 ± 4.5 cm; 66.2 ± 5.4 kg; calorie intake: 1289.3 ± 385.0 kcal/day). The PILATES group participated at a 12-week PILATES program at moderate intensity, 3x/week with each session lasting 60-min. The functional capacity was evaluated in the baseline (PRE), after 12-weeks (POST) and 4-week detraining period (4W_DT). The general index of functional capacity (GIFC) was calculated for all participants. RESULTS: In the PILATES group there was a reduction in performance (increased test time) for the GIFC after 4W_DT in relation to POST (p < 0.05), however, GIFC showing maintenance of performance gain in relation to the PRE (p > 0.05) (PRE: 36.0 ± 5.5 s vs. POST: 27.2 ± 4.0 s vs. 4W_DT: 29.0 ± 4.2 s). The CONTROL group had worse performance than the GIFC POST (35.3 ± 4.6 s) and 4W_DT (35.4 ± 4.6 s) when compared to the PILATES group (F = 106.967; np2 = 0.842; p < 0.001). CONCLUSION: A period of 4W_DT was not able to reduce the functional gains of elderly women with T2D after 12 weeks of PILATES training. These results have a practical application for training professionals, enabling better control and planning of training interruptions on the PILATES method for elderly women with T2D.

Anaerobic Threshold Determination in Cycle Ergometer From Rating of Perceived Exertion.

ABSTRACT: Santos, GAd, Numata-Filho, ES, Rosa, TdS, Passos Neves, RV, Simões, HG, and Moreira, SR. Anaerobic threshold determination in cycle ergometer from rating of perceived exertion. J Strength Cond Res 36(5): 1277-1281, 2022-The objective of the study was to investigate the validity of the rating of perceived exertion threshold (TRPE) for anaerobic threshold (AT) estimation during an incremental test (IT) on a cycle ergometer. Nineteen physically active and healthy men performed an IT on a cycle ergometer. The intensity corresponding to the AT was considered as the point immediately before the abrupt increase in blood lactate concentration ([La]) in the IT. TRPE was determined in the last intensity corresponding to perceptual response previous the 15 arbitrary units (AU) in the 15-point RPE scale. The heart rate (HR), [La], and RPE were obtained at the end of each stage of the IT. There was no significant difference between workload obtained from the AT (150 [120-150] watts) and TRPE (150 [120-150] watts) (p > 0.05). In addition, there were no differences between HR (AT, 139.5 ± 12.7 b·min-1 vs. TRPE, 141.9 ± 14.6 b·min-1, p > 0.05) and [La] (AT, 3.1 [2.8-3.2] mM vs. TRPE, 3.1 [2.9-3.7] mM, p > 0.05). There was a strong correlation between the intensities in AT and TRPE during the IT (r = 0.88). A substantial reliability (intraclass correlation coefficient = 0.84 [0.64-0.94 confidence interval 95%]) was evidenced, as well as a substantial agreement between the AT and TRPE intensities (Pc = 0.84), as confirmed by the Bland-Altman plot (-4.7 [-34.2/24.7]). TRPE was a predictor of the AT (ß = 1.146, R = 0.770, SEE = 15.070, p < 0.01). It can be concluded that TRPE is valid for AT estimation during an IT on a cycle ergometer.

Análise cardiovascular e antropométrica de intervenção com apoio tecnológico em hipertensos: ensaio clínico randomizado / Cardiovascular and anthropometric analysis of intervention with technological support in hypertensives: a randomized clinical trial

O estudo comparou o efeito de intervenções com diferentes estímulos tecnológicos sobre variáveis cardiovasculares e antropométricas de hipertensos. 23 adultos hipertensos foram randomizados em três grupos: grupo intervenção padrão - sem acompanhamento; grupo ligação ­ com acompanhamento por ligação telefônica; grupo aplicativo ­ com acompanhamento por mensagem no grupo do whatsapp. As variáveis foram avaliadas Pré e Pós um período de 12 semanas. Não houve diferença significativa entre grupos com e sem acompanhamento profissional, e nas formas de acompanhamento com diferentes estímulos tecnológicos. Entretanto, houve uma redução significativa da pressão arterial sistólica (p = 0,040), frequência cardíaca (p = 0,010) e da circunferência abdominal (p = 0,039) de hipertensos do grupo intervenção padrão, assim como um efeito na mudança de comportamento. A intervenção influenciou a mudança de comportamento dos voluntários, que se tornaram mais ativos fisicamente e melhoraram hábitos alimentares, contudo não houve diferença nas respostas cardiovasculares e antropométricas entre os grupos

This study compared the effect of interventions with different technological stimuli on cardiovascular and anthropometric variables of hypertensives. 23 hypertensive adults were randomized into three groups: standard intervention group ­ with no follow-up; telephone group ­ with follow-up by phone calls; application group ­ with follow-up by WhatsApp messages. The variables were evaluated before and after a period of 12 weeks. There was no significant difference between the groups with and without professional follow-up, and the same applied to the types of follow-up with different technological stimuli. However, there was a significant reduction of systolic blood pressure (p = 0,040), heart rate (p = 0,010) and waist circumference (p = 0,039) of the hypertensives from the standard intervention group, as well as a behavior change effect. The intervention had influence on the volunteers' behavior change. They became more physically active and improved their eating habits. Yet, there was no difference in the cardiovascular and anthropometric responses among the groups.

Exercício físico e comprimento dos telômeros: uma revisão sistemática nas disfunções crônico-degenerativas / Physical exercise and telomere length: a systematic review in chronic-degenerative dysfunctions

Introdução: Os telômeros estão localizados nas extremidades dos cromossomos e constituem-se de sequências do DNA e proteínas associadas. O exercício físico parece ter relação com um maior comprimento de telômeros, porém, pouco se sabe sobre o impacto deste na dinâmica telomérica de pessoas com disfunções crônico-degenerativas. Objetivo: Revisar sistematicamente a literatura a respeito do efeito do exercício no comprimento dos telômeros em pessoas com disfunções crônico-degenerativas. Métodos: Foram realizadas buscas por dois investigadores independentes nas bases de dados Pubmed, Scopus, Lilacs e Cochrane Controlled Trials Database, analisando publicações nos idiomas inglês e português. Resultados: Foram encontrados 845 estudos, onde destes, quatro atenderam aos critérios de elegibilidade e seguiram para síntese. Conclusão: Embora o encurtamento dos telômeros esteja relacionado ao estilo de vida, herança genética e doenças do envelhecimento, ainda não está claro se o exercício físico pode atenuar tal processo de encurtamento de forma significativa em indivíduos com disfunções crônico-degenerativas, como excesso de peso e diabetes.

Introduction: Telomeres are located at the ends of chromosomes and consist of DNA sequences and associated proteins. Physical exercise seems to be related to a greater telomeres length, but little is known about its impact on the telomere dynamics of people with chronic degenerative dysfunctions. Purpose: Systematically review the literature on the effect of exercise on the telomeres length in people with chronic degenerative disorders. Methods: Searches were carried out by two independent researchers in the databases Pubmed, Scopus, Lilacs e Cochrane Controlled Trials Database, analyzing publications in the English and Portuguese language. Results: A total of 845 studies were found, of which four met the eligibility criteria and followed up for synthesis. Conclusion: Although shortening of telomeres is related to lifestyle, genetic inheritance, and diseases of aging, still unclear physical exercise can attenuate such a shortening process significantly in individuals with chronic-degenerative dysfunctions such as overweight and diabetes.
