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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| 8-minutes short exercise group | Experimental | Participants performed an intervention for 3 sessions/week, over 3 weeks and a cycle ergometer was used. The workout regimen consisted of a structured warm-up lasting 2 minutes. The main exercise phase comprised an 8-minute cycling session performed at 75% of HRmax. Finally, a cool down phase lasting 2 minutes. |
|
| 10-minutes short exercise group | Experimental | Participants performed an intervention for 3 sessions/week, over 3 weeks and a cycle ergometer was used. The workout regimen consisted of a structured warm-up lasting 2 minutes. The main exercise phase comprised an 10-minute cycling session performed at 75% of HRmax. Finally, a cool down phase lasting 2 minutes. |
|
| 15-minutes short exercise group | Experimental | Participants performed an intervention for 3 sessions/week, over 3 weeks and a cycle ergometer was used. The workout regimen consisted of a structured warm-up lasting 2 minutes. The main exercise phase comprised an 15-minute cycling session performed at 75% of HRmax. Finally, a cool down phase lasting 2 minutes. |

| Exercise | Other | Exercise with a cycle ergometer in three phases:
|
| Measure | Description | Time Frame |
|---|---|---|
| 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. | 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% | 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. | Up to 3 weeks |
