Brief Summary

The goal of this randomized controlled trial is to evaluate the effect of environmental context on the health benefits of a standardized walking program in sedentary, overweight older women (aged ≥60 years, BMI ≥24.0 kg/m²) . The main questions it aims to answer are: Does exercising in a high-quality natural tourism environment (Yangshuo) lead to greater improvements in body composition (e.g., body fat percentage) compared to exercising in a conventional institutional setting? Does this environment lead to greater improvements in psychological well-being (e.g., depressive symptoms, sleep quality) than the conventional setting? Researchers will compare a group that walks in the Yangshuo landscape to a group that performs the same walking regimen in a nursing home setting to see if the natural environment amplifies the health benefits of the exercise. Participants in both groups will take part in a supervised, 10-week walking program (5 days/week, 60 mins/session). All participants will have their physiological (e.g., weight, body fat, strength) and psychological (e.g., mood, sleep, quality of life) health measured before and after the program.

Outcome Measures

Primary Outcomes (10)

• Change in Body Weight

  Measured in kilograms (kg) using a multi-frequency bioelectrical impedance analysis device (InBody 770) under standardized conditions.

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Body Mass Index (BMI)

  Calculated as weight in kilograms divided by height in meters squared (kg/m²). Height measured at baseline using a stadiometer; weight measured at each time point using the InBody 770 device.

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Body Fat Percentage

  Measured as percentage (%) of total body weight using multi-frequency bioelectrical impedance analysis (InBody 770) under standardized conditions.

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Lower-body Muscular Endurance

  Assessed by the 30-second chair stand test, measuring the number of full stands completed in 30 seconds from a seated position. Higher numbers indicate better lower-body muscular endurance.

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Handgrip Strength

  Measured in kilograms (kg) using a calibrated handgrip dynamometer. Participants performed the test with their dominant hand, and the best of two trials was recorded. Higher values indicate greater handgrip strength.

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Depressive Symptoms

  Assessed using the Center for Epidemiologic Studies Depression Scale (CES-D) . This 20-item scale measures the frequency of depressive symptoms experienced in the past week. Total scores range from 0 to 60, with higher scores indicating more severe depressive symptoms (a worse outcome) .

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in State Anxiety

  Assessed using the State subscale of the State-Trait Anxiety Inventory (STAI-S) . This 20-item scale measures transient anxious emotional states at the moment of assessment. Total scores range from 20 to 80, with higher scores indicating higher levels of state anxiety (a worse outcome) .

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Mental Health-Related Quality of Life

  Assessed using the Mental Component Summary (MCS) of the 36-Item Short Form Health Survey (SF-36) . This score is a standardized T-score based on normative data, with a population mean of 50 and a standard deviation of 10. Higher scores indicate better mental health-related quality of life (a better outcome) .

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Sleep Quality

  Assessed using the Pittsburgh Sleep Quality Index (PSQI) . This 19-item instrument assesses sleep quality and disturbances over a one-month period. The global score ranges from 0 to 21, with higher scores indicating poorer sleep quality (a worse outcome) . A global score \>5 is indicative of poor sleep quality.

  Baseline (Week 0) and within one week post-intervention (Week 10)

• Change in Perceived Mastery

  Assessed using the Pearlin-Schooler Mastery Scale. This 7-item scale measures the extent to which individuals perceive themselves as having personal control over factors that significantly impact their lives. Total scores range from 7 to 28, with higher scores indicating a stronger sense of personal mastery (a better outcome) .

  Baseline (Week 0) and within one week post-intervention (Week 10)

Study Arms (2)

Experimental: Natural Environment Group (NCE)

EXPERIMENTAL

Participants in this group will complete a 10-week supervised walking program (5 days/week, 60 mins/session) conducted along scenic riverside paths in the Yangshuo karst landscape. They will be accommodated in a local homestay with direct views of the mountains. Exercise intensity is targeted at 60-70% of heart rate reserve, monitored by Polar H10 sensors.

Behavioral: Walking Program in Natural Tourism Environment

Active Comparator: Conventional Environment Group (CCE)

ACTIVE COMPARATOR

Participants in this group will complete an identical 10-week supervised walking program (5 days/week, 60 mins/session) conducted on paved urban streets surrounding a local nursing home. They will reside in their usual accommodation within the nursing home. Exercise intensity is targeted at 60-70% of heart rate reserve, monitored by Polar H10 sensors.

Behavioral: Walking Program in Conventional Institutional Environment

Interventions

Walking Program in Natural Tourism Environment BEHAVIORAL

A 10-week supervised walking program conducted in the high-quality natural tourism environment of Yangshuo. Participants are accommodated in a local homestay with direct views of the iconic karst mountains. Walking sessions are conducted on pre-selected, scenic, low-traffic riverside paths. The program consists of group walking 5 days/week, 60 mins/session, at a target intensity of 60-70% heart rate reserve, objectively monitored using Polar H10 chest-worn heart rate sensors.

Experimental: Natural Environment Group (NCE)

Walking Program in Conventional Institutional Environment BEHAVIORAL

A 10-week supervised walking program conducted in a standard institutional setting. Participants reside in a local nursing home with views of institutional buildings or internal courtyards. Walking sessions are conducted on pre-measured, paved urban streets surrounding the nursing home. The program consists of group walking 5 days/week, 60 mins/session, at a target intensity of 60-70% heart rate reserve, objectively monitored using Polar H10 chest-worn heart rate sensors to match the exercise dose with the experimental group.

Active Comparator: Conventional Environment Group (CCE)
