“…However, the 50% HRR group [2] and 30% HRR group [10] did not show a significant increase in VO 2 peak compared to a control group. In contrast, previous studies found a significant increase in VO 2 peak in low, moderate or high intensity training groups in elderly [19], patients with chronic heart failure [20] and cancer survivors [21]. One of the differences between these studies and our study is the type of training, i.e.…”

“…Low-intensity lower-body aerobic exercise training (25% -35% or 40% -50% HRR, 3 × 14 -32 min/per week for 10 weeks) performed by cancer survivors revealed that both training groups did show a significant decrease in body fat, an improvement in aerobic capacity and in quality of life compared to the non-training control group [21]. Another study [19] found that cycling exercise at a low intensity (30% -45% HRR, 3 × 25 min per week for 9 weeks) is an adequate training stimulus in older individuals and produces changes in peak oxygen uptake that are comparable to those elicited by high-intensity (60% -75% HRR) training. Similar increases in VO 2 peak were found between low (30% HRR) and high (70% HRR) walking exercise intervention groups in postpartum women [22].…”

The purpose of this study was to compare the effects of intensity and duration of training on physical capacity in a 7 weeks hand rim wheelchair training in able-bodied men. Thirty-six able-bodied men participated in three groups: a 30% heart rate reserve (HRR) 70 min training group (N = 14), a 70% HRR 30 minutes training group (N = 13) and a 30% HRR 30 minutes training group (N = 9). All groups trained 3 times per week for 7 weeks on a treadmill. Pre and post tests on a wheelchair ergometer comprised a submaximal test at 20% and 40% of the estimated peak power output , in which submaximal heart rate, oxygen uptake and mechanical efficiency were determined. In maximal exercise tests, maximal isometric strength, sprint power, peak power output and peak oxygen uptake were measured. No significant differences were found between the training groups on submaximal and maximal parameters. It can be concluded that, in persons new to wheelchair use, seven weeks of wheelchair endurance training at an intensity of 30% HRR for 30 minutes is as effective as a training at a higher intensity (70% HRR) or with a longer duration (70 min).

“…Studies [1][2][3][4][5][6][7][8] have shown that elderly people are able to tolerate aerobic exercise and that cardiovascular changes have resulted from both high-and low-intensity exercise programs. However, the benefits of aerobic exercise extend beyond cardiovascular changes.…”

Effect of Aerobic Exercise on Tracking Performance in Elderly People: A Pilot Study

et al. 2001

Background and Purpose. Although much is known about the benefits of aerobic exercise on cardiovascular health, little research has been done on the effect of aerobic exercise on motor performance. This study examined whether aerobic exercise has an effect on visuospatial information processing during finger-movement tracking in elderly subjects. Subjects. Fifteen elderly subjects (mean ageϭ83.2 years, SDϭ5.7, rangeϭ72-91) from a senior housing complex were randomly assigned to a control group or an experimental (exercise) group. Twelve subjects completed the study, and data obtained for 10 subjects were used for data analysis (2 control subjects were eliminated to allow for matched-pairs analysis between the experimental and control groups). The control group (nϭ5) had a mean age of 80.2 years (SDϭ7.8). Subjects in the experimental group (nϭ5) had a mean age of 84.8 years (SDϭ2.5). Methods. The intervention consisted of group exercise 3 times a week for 8 consecutive weeks, and included calisthenics (eg, marching in place, side stepping, mock boxing), stationary bicycling, and walking. A finger-movement tracking test and submaximal graded exercise tolerance step tests were performed before and after training to determine changes in finger-movement tracking and any aerobic training effects. Results. Matched-pairs t tests showed a difference in tracking from pretest to posttest in the experimental group compared with the control group.Step test performance did not differ between the 2 groups. Discussion and Conclusion. The results of this small-scale study with a limited number of subjects indicate that, for elderly people, finger-movement tracking performance can improve with aerobic exercise, despite the absence of an aerobic training effect. Possible mechanisms for the treatment effect on information processing are discussed. [Bakken RC, Carey JR, Di Fabio RP, et al.

“…Related literature on persons without symptoms of OA suggests that low-intensity aerobic exercise can be as beneficial to improving physiological status as high-intensity exercise (10,11,15,16). Reported ranges for low intensity are 30%-45% of heart rate reserve (HRR), whereas high-intensity exercise varies in range from 60%-75% HRR.…”
