Effects of resistance training and aerobic exercise in elderly people concerning physical fitness and ability: a prospective clinical trial

Abstract

Objective:To compare the effects of physical fitness and function on older adults in two programs of supervised exercise activity: resistance training and aerobic exercise.Methods:This study is a randomized, prospective clinical trial composed of sedentary elderly people who did not have contraindications to exercise. Participants were divided into two groups: group one performed 6 exercises of resistance training twice a week, and group two participated in walking activity for 30 minutes twice a week. Functional assessment (time 0,6 and 12 months) was measured by the Short Physical Performance Battery (time to sit or stand, gait speed, and balance), flexibility test, and the six-minute walking test. We randomly selected 96 patients: 46 in the Resistance Training Group and 50 in the Aerobic Exercise Group. In the Resistance Training Group, 46 attended the first assessment and 20 attended until the third section. In the Aerobic Exercise Group, 50 attended the first assessment and 12 attended until the third assessment.Results:Mean age was 68.8 years in the Resistance Training Group and 69.1 years in the Aerobic Exercise Group. The Resistance Training Group showed improvement in the sit/ stand (p=0.022), balance with feet in a row (p=0.039) and queued (p=0.001). The second showed a statistical difference in speed and balance with the feet lined up and the feet together (p=0.008; p=0.02; and p=0.043, respectively). Concerning flexibility, the Resistance Training Group had improvement (p=0.001), whereas in the Aerobic Exercise Group, no significant difference was seen (p=0.359). Both groups had improvement in the six-minute walking test, but no significant improvement was seen in the Aerobic Exercise Group (p=0.033).Conclusion:Both groups showed improvement in physical fitness. No statistical difference was seen when groups was compared in the short physical performance battery, flexibility, and six-minute walking test.Clinical trial register: UTN: U1111-1141-3066

The role of “non-traditional” physical activities in improving balance in older adults: A review

“…Effects of resistance training compared to aerobic exercise in elderly people concerning physical fitness and ability were investigated [47]. Resistance exercises were performed in an experimental gym for 1 hour, twice a week for 12 months, with the aerobic activity performed on a walking track, with training lasting for 30 minutes, twice a week for 12 months.…”

Programa de ejercicio estructurado es viable y mejora la capacidad funcional en adultos mayores en Puerto Rico

“…Incluir ejercicios de flexibilidad al inicio y al finalizar cada sesión del PECE pudo haber influenciado estos resultados. Por ejemplo, se ha observado que los adultos mayores que participan en actividades aeróbicas en el agua que incluyen periodos de estiramiento (Clark, 1994) y entrenamiento de resistencia fuera del agua (Roma et al, 2013) mejoran significativamente la flexibilidad. En otro estudio se reportó un aumento significativo en la flexibilidad entre adultos mayores luego de 12 meses en un programa de "Tai Chi" (Lan, Lai, Chen, & Wong, 1998).…”

Avaliação Da Flexibilidade E Força Muscular De Membros Inferiores Em Idosas Praticantes De Hidroginástica

“…Nota-se que este processo de perda de massa muscular ocorre primeiro e em maior grau nos membros inferiores (MMII), uma vez que os idosos tendem a passar mais tempo sentados, solicitando mais os membros superiores (MMSS) (ROMA et al, 2013).…”
