Artigo Agreement between upper and lower limb measures to identify older adults with low skeletal muscle strength, muscle mass and muscle quality(PLoS One, 2022-01) Fayh, Ana Paula Trussardi; Alves, Charles Phillipe de Lucena; Câmara, Marcyo; Macêdo, Geovani Araújo Dantas; Freire, Yuri Alberto; Silva, Raíssa de Melo; Pereira, Ronildo Paulo; Farias Júnior, Luiz Fernando; Mortatti, Arnaldo Luis; Costa, Eduardo CaldasBackground: Identifying low skeletal muscle strength (SMS), skeletal muscle mass (SMM) and skeletal muscle quality (SMQ) is pivotal for diagnosing sarcopenia cases. Age-related declines in SMS, SMM, and SMQ are dissimilar between the upper (UL) and lower limbs (LL). Despite this, both UL and LL measures have been used to assess SMS, SMM and SMQ in older adults. However, it is not clear whether there is agreement between UL and LL measures to identify older adults with low SMS, SMM and SMQ. Objective: To investigate the agreement between UL and LL measures to identify older adults with low SMS, SMM and SMQ. Methods: Participants (n = 385; 66.1 ± 5.1 years; 75,4% females) performed the handgrip strength test (HGS) and the 30-s chair stand test (CST) to assess UL- and LL-SMS, respectively. The SMM was assessed by dual-energy X-ray absorptiometry (DXA). The UL-SMQ was determined as: handgrip strength (kgf) ÷ arm SMM (kg). LL-SMQ was determined as: 30-s CST performance (repetitions) ÷ leg SMM (kg). Results below the 25th percentile stratified by sex and age group (60–69 and 70–80 years) were used to determine low SMS, SMM and SMQ. Cohen’s kappa coefficient (κ) was used for the agreement analyses. Results: There was a slight and non-significant agreement between UL and LL measures to identify older adults with low SMS (κ = 0.046; 95% CI 0.093–0.185; p = 0.352). There was a moderate agreement to identify low SMM (κ = 0.473; 95% CI 0.371–0.574; p = 0.001) and a fair agreement to identify low SMQ (κ = 0.206; 95% CI 0.082 to 0.330; p = 0.005). Conclusion: The agreement between UL and LL measures to identify older adults with low SMS, SMM and SMQ is limited, which might generate different clinical interpretations for diagnosing sarcopenia casesArtigo Efeito do tempo sentado prolongado sobre marcadores cardiometabólicos em adultos fisicamente ativos e inativos: um estudo piloto(Revista Brasileira de Atividade Física & Saúde, 2019-08) Fayh, Ana Paula Trussardi; Macêdo, Geovani Araújo Dantas; Freire, Yuri Alberto; Browne, Rodrigo Alberto Vieira; Farias-Junior, Luiz Fernando; Cabral, Ludmila Lucena Pereira; Souto, Gabriel Costa; Sousa, Iasmin Matias de; Farias Júnior, José Cazuza de; Costa, Eduardo CaldasO objetivo deste estudo foi analisar o efeito do tempo sentado prolongado sobre marcadores cardio-metabólicos em adultos fisicamente ativos e inativos. Participaram do estudo 10 adultos fisicamente ativos (27,30 ± 4,90 anos de idade) e 11 fisicamente inativos (26,27 ± 3,17 anos de idade). Todos realizaram uma sessão de tempo sentado prolongado de 10 horas, com quatro refeições padroniza-das. Os níveis de glicose e pressão arterial foram mensurados no jejum, antes e 1 hora após cada refeição e também 2 horas após o almoço. Os níveis de triglicerídeos foram medidos no jejum, 2 e 3,5 horas após o almoço. O modelo linear generalizado foi utilizado para comparar a área sob a curva incremental (ASCi) dos níveis de glicose e triglicerídeos e a área sob a curva (ASC) dos níveis de pressão arterial entre os grupos, com ajuste pelos valores de linha de base. O grupo fisicamente ativo apresentou menor ASCi para os níveis de glicose no período de 10 horas (β = -5,55 mg/dL/10h; IC95%: -9,75; -1,33; p = 0,010) e no período da manhã (β = -7,05 mg/dL/5h; IC95%: -12,11; -1,99; p = 0,006) comparado ao grupo fisicamente inativo. Não houve diferença da ASCi dos triglicerídeos (p = 0,517) e na ASC da pressão arterial (p = 0,145) entre os grupos. Em conclusão, adultos fisicamente ativos apresentaram melhor controle glicêmico comparados àqueles fisicamente inativos durante a exposição a tempo sentado prolongadoArtigo Effects of high-intensity interval and moderate-intensity continuous exercise on physical activity and sedentary behavior levels in inactive obese males: a crossover trial(Journal of Sports Science and Medicine, 2019-08) Fayh, Ana Paula Trussardi; Santos, Victor Oliveira Albuquerque dos; Browne, Rodrigo Alberto Vieira; Souza, Daniel Costa de; Matos, Victor Araújo Ferreira; Macêdo, Geovani Araújo Dantas; Farias Junior, Luiz Fernando; Farias Junior, José Cazuza; Costa, Eduardo CaldasA total of 17 participants (30.2 ± 4.8 years; 35.4 ± 4 kg/m2; 38.2 ± 3.6 % body fat) were enrolled in this randomized crossover trial to analyze the effects of a single session of high-intensity interval (HIIE) and moderate-intensity continuous exercise (MICE) on the physical activity and sedentary behavior levels in inactive obese males. The participants performed two exercise sessions and one control session (no exercise): i) low-volume HIIE (10 x 60 s at 90% of maximal aerobic velocity [MAV] interspaced by 60 s at 30% of MAV); ii) MICE (20 min at 70% of maximum heart rate); and iii) control (25 min in a seated position). After all sessions, the physical activity and sedentary behavior levels were monitored by accelerometer over seven consecutive days. No differences in the physical activity (activity counts, and time spent at light, moderate, and vigorous intensities) and sedentary behavior (time spent at sedentary behavior, breaks, and bouts) levels were found among the sessions (HIIE, MICE and control) (p > 0.05). In summary, a single session of HIIE and MICE does not change the physical activity and sedentary behavior levels in inactive obese males. Therefore, low-volume of both high- and moderate-intensity exercise should be considered for inactive obese males given that it does not reduce the physical activity level or increase the time spent at sedentary behavior
