Previous studies have found that strength training alone- or combined with AT was associated with a 11 to 20% increase in distance walked in 6 min in older women with CAD or heart failure. We found that 8 weeks of AT or COMT was associated with a 10% increase in the distance walked in 6 min. Thus, the heightened V02peak that occurs with AT or COMT also increases aerobic endurance, which allows older women with CAD to increase the distance that they can walk during a 6-min period.

At baseline, the social QOL of the AT subjects was significantly greater than that of COMT subjects (Table 1). No significant difference was found between the groups for any other baseline measure (Table 1). generic wellbutrin
Effects of Exercise Training on Vo2peak and Distance Walked in 6 min
Both AT and COMT resulted in a similar increase in peak exercise ventilation, oxygen pulse, V02peak, and distance walked in 6 min (Fig 2). No significant change in peak heart rate was found after training (pretraining, 115 ± 19 beats/min, vs posttraining. 119 ± 20 beats/min). Continue reading
The 6-min walk test was performed in accordance with the American Thoracic Society guidelines.
Upper- and Lower-Extremity Maximal Strength Testing
Subjects were shown the correct technique required to perform eight (chest press, shoulder press, vertical row, triceps extension, biceps curl, latissimus dorsi pull down, leg extension, and leg curl) strength exercises, after which time they were given an opportunity to perform each exercise. The heaviest weight lifted once while adhering to strict technique was used as the one-repetition maximum (1RM). The 1RM test was repeated a second time within a 1-week period, and the highest score of the 2 days was used as the baseline score. Continue reading
Exercise training is an important intervention that can reverse the decline in peak aerobic power (V02peak) and muscle strength5-8 that occurs in older individuals with coronary artery disease (CAD). The improvement in V02peak has prognostic implications, as Kavanagh et al recently reported that a 1 mL/kg/min increase in V02peak was associated with a 10% reduction in cardiac mortality in older women with CAD. A limitation of previous cardiac rehabilitation exercise studies was the exclusion of older women with CAD as study participants. Older women with CAD may have the most to gain from participating in an exercise rehabilitation program because they have a V02peak that is 26 comitant improvement in overall quality of life (QOL) in older women with CAD. The purpose of this investigation was to examine the effects of 8 weeks of aerobic training (AT) or combined aerobic and strength training (COMT) on V02peak, distance walked in 6 min, upper- and lower-extremity maximal strength, and QOL in older women with CAD. We hypothesized that COMT would result in a greater increase in overall physical fitness and QOL compared to AT. buy glucophage online Continue reading
