Abstract
Declines in maximal aerobic power and skeletal muscle force production with advancing age are examples of functional declines with aging, which can severely limit physical performance and independence, and are negatively correlated with all cause mortality. It is well known that both endurance exercise and resistance training can substantially improve physical fitness and health-related factors in older individuals. Circuit-based resistance training, where loads are lifted with minimal rest, may be a very effective strategy for increasing oxygen consumption, pulmonary ventilation, strength, and functional capacity while improving body composition. In addition, circuit training is a time-efficient exercise modality that can elicit demonstrable improvements in health and physical fitness. Hence, it seems reasonable to identify the most effective combination of intensity, volume, work to rest ratio, weekly frequency and exercise sequence to promote neuromuscular, cardiorespiratory and body composition adaptations in the elderly. Thus, the purpose of this review was to summarize and update knowledge about the effects of circuit weight training in older adults and elderly population, as a starting point for developing future interventions that maintain a higher quality of life in people throughout their lifetime.
Highlights
The biological aging process is associated with a structural and functional deterioration in most physiological systems, including the neuromuscular and cardiovascular systems
The present results clearly demonstrate that the performance of high-resistance circuit (HRC) training can be as effective as traditional heavy strength (TS) training for improving muscle mass, strength and bone mineral density (BMD), but is more effective at stimulating positive cardiovascular and body composition adaptations in older individuals
The present findings are important because they indicate that HRC training might be a time effective way of triggering multiple positive physiological adaptations in this population
Summary
The biological aging process is associated with a structural and functional deterioration in most physiological systems, including the neuromuscular and cardiovascular systems. These age-related changes affect a broad range of tissues, organ systems and functions which, cumulatively, can negatively impact activities of daily living in older adults (Chodzko-Zajko et al, 2009). ⁎ Corresponding author at: Facultad de Ciencias de la Actividad Física y del Deporte, Universidad Católica San Antonio de Murcia.
