Use behavior and spatial characteristics of National Fitness Routes in China: an in situ observational study.

TL;DR

OGs use represented only a small proportion of activities observed within NFRs, indicating that these spaces function not only as settings for PA but also as important places for recreation and social interaction.

Key Findings

Outdoor gym equipment (OGs) accounted for only 15.2% of all observation records across four National Fitness Routes.

  • A total of 9,704 person-observation records were collected across four representative NFRs in Yangling District, Shaanxi Province, China.
  • Observations were conducted during three seasons using the System for Observing Play and Recreation in Communities (SOPARC).
  • Seniors represented the largest user group of outdoor gym equipment.
  • The air walker, leg massager, and waist/back massager were the most frequently used types of OGs.

Sitting, standing, and walking were the predominant activities observed within National Fitness Routes.

  • These sedentary and light-intensity behaviors dominated activity patterns across all four NFR sites.
  • Behavioral activities exhibited clear spatial clustering around seating areas, dedicated pathways, and open activity spaces.
  • Kernel density estimation and behavior mapping were used to examine the spatial distribution of activities.
  • The findings indicate NFRs function as places for recreation and social interaction, not only physical activity.

Age, time period, week period, temperature, air quality, and site characteristics were independently associated with moderate-to-vigorous physical activity (MVPA).

  • Binary logistic regression was performed to identify factors associated with MVPA after adjustment for potential confounders.
  • Gender and season were not independently associated with MVPA after adjustment.
  • Both environmental factors (temperature, air quality) and temporal factors (time of day, weekday vs. weekend) were significant predictors.
  • Site characteristics were also independently associated with MVPA, suggesting physical design of NFRs influences activity intensity.

NFRs serve as important social and recreational spaces beyond their intended physical activity promotion function.

  • OGs use represented only a small proportion of total activities observed within NFRs.
  • The spaces attracted diverse user behaviors including sedentary and light-intensity activities.
  • Seniors were the largest user group, suggesting NFRs are particularly valued by older adults for recreation and social interaction.
  • The authors note these spaces function 'not only as settings for PA but also as important places for recreation and social interaction.'

Integrating age-appropriate outdoor gym equipment with walking paths, seating areas, tree shade, and flexible open spaces may better support diverse recreational behaviors and promote physical activity.

  • This recommendation is based on observed spatial clustering of activities around seating areas, dedicated pathways, and open activity spaces.
  • The findings are described as providing 'evidence-based guidance for optimizing the planning and spatial design of NFRs.'
  • The study calls for design that supports 'healthier and more inclusive public fitness environments.'
  • The National Fitness Route program is described as an increasingly popular government-funded solution to declining population physical activity levels in China.

What This Means

This research suggests that China's National Fitness Routes (NFRs) — outdoor public spaces equipped with exercise machines funded by the government — are not being used primarily for vigorous exercise. Across nearly 10,000 observations at four different NFR sites over multiple seasons, researchers found that outdoor gym equipment was involved in only about 15% of all recorded activities. Most people were sitting, standing, or walking rather than using the exercise machines, and older adults were the most frequent visitors. The most popular pieces of equipment were the air walker, leg massager, and waist/back massager. The study also found that factors like time of day, day of the week, temperature, air quality, and the physical design of the site all influenced whether people engaged in moderate-to-vigorous physical activity, while gender and season did not. Activities tended to cluster spatially around benches, pathways, and open areas rather than around the gym equipment itself, suggesting these spaces are valued as much for socializing and light recreation as for structured exercise. This research suggests that simply installing outdoor gym equipment is not sufficient to drive high levels of physical activity in these spaces. The findings point toward a more holistic design approach — combining age-appropriate exercise machines with shaded seating, walking paths, and open flexible areas — to better serve the diverse needs of community members, particularly older adults, and to more effectively encourage physical activity in public spaces.
