Effects of Exercise Training on Physical Activity in Older People: A Randomized Controlled Trial.

Abstract

Background: Recent randomized controlled trials indicated that exercise training for elderly significantly increased their physical fitness. However, very few studies have examined changes in physical activity after exercise training. The purpose of this study was to investigate whether six-month exercise training for older adults can increase and maintain their physical activity in daily life.Methods: Sixty-two men and women aged 60 to 81 years (mean age 67.1 years), living in communities, were randomly allocated into an exercise group (n=32) or a control group (n=33). The intervention started in April 1998 and lasted for 25 weeks. The exercise regimen consisted of endurance training and resistance exercises in a two-hour class conducted at least twice a week. The subjects completed a physical activity diary at each pre-intervention (March 1998), post-intervention (September 1998) and follow-up (April 1999) measurement of physical activity. Physical activity, expressed as total daily energy expenditure, was calculated by multiplying the amount of time spent in each activity and the corresponding METs.Results: Total daily energy expenditure significantly increased from 40.8 kcal/kg/day to 43.5 kcal/kg/day in the exercise group (p=0.03), but did not change in the control group. At the follow-up measurement, the mean total daily energy expenditure in the exercise group remained significantly higher, by 1.7 kcal/kg/day, than that at the pre-intervention (p=0.05).Conclusions: This randomized controlled trial indicated that exercise training for elderly was effective in increasing physical activity in daily life.

Energy Expenditure Responses To Exercise Training In Older Women

“…Participants in our study were older than in these studies; therefore, extending the findings to an older population. Several previous studies involving older adults suggested decreased nonexercise physical activity (Meijer et al 1999(Meijer et al , 2000 and/or NEAT (Goran and Poehlman 1992;Morio et al 1998;Colley et al 2010) following exercise intervention, but others reported increased or unchanged nonexercise physical activity (Washburn and Ficker 1999;Fujita et al 2003;Church et al 2009). Our study showed that NEAT and nonexercise physical activity did not change in the overall sample.…”

Research on the impact of exercise on body composition of elderly

“…Значај физичког вежбања у функцији очувања и унапређења здравља, побољшања телесног саставастарих особа потврђен је у многим студијама (Grant, Todd, Aitchison, Kelly, & Stoddart, 2004;Coker, Williams, Kortebein, Sullivan, & Evans, 2009;Bakhtiari et al, 2012;Andersen, Schmidt, Pedersen, Krustrup & Bangsbo, 2016) .Савремен начин живота и рада је такав да је технолошки развој примораo човека да се мање фокусира на физичке активности (Weineck, 2004). Aктиван начин живота и свакодневна физичка активност умереног карактера имају значајан утицај на телесни састав старијих особа (Fujita, Nagatomi, Hozawa, Ohkubo, Sato, Anzai, & Tsuji, 2003), јер редовним физичким вежбањем се смањује ризик од настанка разних обољења (ACSM, 1998). Старије особе имају више физичких или медицинских ограничења у односу на млађе особе, и због тога интензитет вежбања је углавном мањи и количина вежбања опада са старењем (Kallinen, & Markku, 1995;Taunton et al, 1997).…”

Circulatory Functions to Maintain Physical Activity of Daily Life in Elderly People

“…Furthermore, improved physical fi tness due to training was clarifi ed to increase and maintain physical activity in daily life of older adults (Fujita, et al, 2003), which will lead to improvement in quality of life.…”
