Purpose: To determine the effects of three Short Moderate Intensity Continuous Training (SMICT) exercise programs with different durations, on functional capacity, resting heart rate (RHR) and physical activity enjoyment in sedentary women. Methods: A randomized clinical trial was performed. 45 sedentary women were randomly allocated to either a: i) 8-minutes short exercise group; ii) 10-minutes short exercise group; and iii) 15-minutes short exercise group. All three groups received a short exercise training program at moderate intensity for 3 sessions/week, over 3 weeks. Before and after the interventions, functional capacity was evaluated through the 6-minute walking test, and RHR with a pulse oximeter. Physical activity enjoyment was measured with the Physical Activity Enjoyment Scale after the intervention.
Sedentary lifestyles contribute to 3.2 million annual deaths globally, correlating with increased risks of cardiovascular diseases, obesity, and certain cancers. With women showing notably low physical activity rates, implementing tailored exercise interventions becomes crucial to enhance their activity levels and functionality, potentially mitigating risks associated with high resting heart rates linked to increased mortality, particularly from cardiovascular causes. This was a randomized clinical trial involving 45 sedentary women split into three groups: 8-minute, 10-minute, and 15-minute exercise durations. All groups underwent moderate-intensity short exercise programs, differing only in duration. Functional capacity (measured by the 6-minute walking test) and resting heart rate (RHR) were assessed at baseline and after the 3-week intervention. Physical activity enjoyment was measured at the intervention's end.

Exercise with a cycle ergometer in three phases: * Warm-up: the exercise intensity was determined at 50-60% of HRmax obtained in the effort test, and lasted 2 minutes. * Short exercise at moderate intensity for 8, 10 or 15 minutes according to group allocation. The exercise was cycling at 75% HRmax determined with an effort test. * Cool down: the exercise intensity was determined at 50-60% of HRmax obtained in the effort test, and lasted 2 minutes.

Functional capacity
6-minutes walking test (6MWT). This test consists of calculating the distance covered by the participant who was instructed to walk as quickly as possible along a 30-meter hallway without running for six minutes. Greater number of meters covered, better functional capacity.
Time frame: Up to 3 weeks
Resting heart rate
Resting heart rate was measured with a pulse oximeter. The normal values for oxygen saturation (SpO2) in healthy adults measured by a pulse oximeter are 95% to 100%
Time frame: Up to 3 weeks
Physical activity enjoyment
Physical activity enjoyment was measured with a modified version of the Physical Activity Enjoyment Scale (PACES). The scale is comprised of 17 items that are assessed using a 7-point bipolar scale. The final enjoyment score is calculated, and possible scores range from 17 (representing not enjoyable) to 68 (indicating neutral) to 119 (reflecting enjoyable). The higher score indicates greater enjoyment.
Time frame: Up to 3 weeks
