Cardiac rehabilitation (CR) has been recommended to provide exercise
guidance poststroke. However, it has not been established whether minimal
exercise training levels, sufficient for obtaining health benefits, can be
attained in CR. Therefore, we assessed the ability of stroke patients to achieve
recommended exercise levels during a single standard CR session following
completion of CR. METHODS: : Sixteen patients (10 males and 6 females) with
mild/moderate motor impairments who had completed CR participated in the study.
Resting metabolic rate and oxygen uptake during 30 minutes each of aerobic and
resistance training (AT, RT, respectively) were assessed by ambulatory oxygen
monitor. Obtained values were compared with recommended minimal levels, that is,
20 or more minutes of exercise at 40% or more of peak oxygen uptake ((Equation is
included in full-text article.)O2peak), 30 or more minutes of exercise at 3 or
more metabolic equivalents (METs) (multiples of resting metabolic rate), and an
energy expenditure of approximately 200 kcal per session. RESULTS: : Mean time
sustaining 40% or more of (Equation is included in full-text article.)O2peak was
47.6 +/- 9 minutes, exceeding the minimal target of 20 minutes (P < .001). Time
sustaining 3 or more METs was 30.8 +/- 12.2 minutes, matching the target of 30
minutes (P = .8). Total energy expenditure (252 +/- 49.9 kcal) was significantly
greater than the target value of 200 kcal (P = .001). CONCLUSIONS: : Chronic
stroke patients with mild/moderate motor impairments are able to meet or exceed
minimal recommended exercise target levels for intensity, duration, and energy
expenditure during a typical exercise session consisting of 30 minutes of AT
combined with 30 minutes of RT after completing CR. These data contribute to the
evidence promoting the efficacy and feasibility of CR for people following
stroke.
