Continuous assistive-passive exercise and cycle ergometer training in sedentary women

Area of Science:

• Exercise Physiology
• Gerontology
• Sports Science

Background:

• Continuous assistive-passive exercise (CAPE) is a novel exercise modality gaining popularity among older females.
• Sedentary postmenopausal women (PMW) are a key demographic for evaluating the health benefits of new exercise interventions.

Purpose of the Study:

• To evaluate the efficacy of Continuous Assistive-Passive Exercise (CAPE) compared to traditional cycle ergometer training in sedentary postmenopausal women.
• To assess the impact of CAPE and cycle ergometer training on body composition and aerobic power (VO2max).

Main Methods:

• 43 sedentary PMW were randomized into three groups: CAPE training (10 min, twice weekly), cycle ergometer training (30 min, twice weekly at 70-85% max heart rate), and a sedentary control group.
• Intervention duration was 12 weeks.
• Measurements included body girths (sigma 7G), skinfolds (sigma 4SF), weight, VO2max, and caloric intake, assessed pre- and post-training.

Main Results:

• No significant differences in changes to caloric intake, body girths, or skinfolds were observed among the groups.
• The cycle ergometer group showed a significant decrease in weight (1.1 kg) and a significant increase in VO2max (9.2%).
• The CAPE group exhibited a significant decrease in VO2max (P = 0.04).

Conclusions:

• Continuous assistive-passive exercise (CAPE) does not appear to improve body composition or aerobic capacity in sedentary postmenopausal women.
• Traditional cycle ergometer training, performed twice weekly, is effective for significantly increasing aerobic power (VO2max) in this population.
