This study aims to analyze the agreement of cardiopulmonary variables between a cardiopulmonary exercise test with elastic resistance (CPxEL) and high-intensity interval exercise with elastic resistance (EL-HIIE). Methods: Twenty-two physically independent participants were recruited. Visit one consisted of conducting a health survey and anthropometric assessment. On visit two, the participants performed CPxEL. After seven days, on visit three, the participants performed EL-HIIE. The CPxEL was carried out on a rubber mat demarcated by lines representing eight stages. The test consisted of alternating back and forth steps against elastic resistance. The increments were performed at a rate of one stage per minute, following a cadence controlled by a metronome calibrated by beats per minute (bpm). The EL-HIIE was performed at the stage corresponding to an intensity of ~85% VO_2max, as determined by CPxEL. The EL-HIIE consisted of 10 × 1 min (work):1 min (passive rest), with a cadence of 200 bpm. Cardiopulmonary parameters, heart rate (HR), and oxygen consumption (VO₂) were measured during exercise. Bland–Altman was applied to analyze the agreement between the HR and VO₂ found in EL-HIIE and the values prescribed by CPxEL (~85–90% VO_2max). Results: The HRpeak and VO₂peak in the EL-HIIE showed good agreement with the VO_2CPxEL and HR_CPxEL values, showing an average difference of (−1.7 mL·kg⁻¹·min⁻¹) and (0.3 bpm). Conclusions: The results of the present study demonstrate the agreement of cardiopulmonary variables between the CPxEL and the EL-HIIE. Therefore, for a more specific prescription of EL-HIIE intensity, CPxEL can be used.

Introdução: O programa público de orientação ao exercício (PROEF) facilita a adesão à atividade física. Entretanto, os homens tendem a buscar menos esses serviços, mesmo sendo mais vulneráveis a doenças crônicas. Objetivo: Avaliar os efeitos das intervenções do PROEF nas variáveis hemodinâmicas e metabólicas de homens. Métodos: Oito homens (65,5 ± 13,3 anos) foram avaliados antes e após 1 ano de adesão ao PROEF. Foram aplicadas 3 sessões/semana, de caminhada (~30 min, 3x), exercícios com resistência elástica para membros superiores (1x) e intervalado com resistência elástica (1x). Foi utilizado teste t pareado e tamanho de efeito. Resultados: Houve redução da massa corporal, IMC, circunferência abdominal e no colesterol LDL (P < 0,05); e aumento do HDL (P ≤ 0,05). A PAS e PAD reduziu 10,8 e 4,9 mmHg (P > 0,05; TE – 0,54 e 0,45). Conclusão: Um ano de intervenção no PROEF melhorou os parâmetros hemodinâmicos, metabólicos e antropométricos de homens de meia idade e idosos.
