Key Highlights

• Students’ perceptions of their campus sports environment predict later physical fitness largely through two psychosocial pathways: peer support and perceived physical literacy. Together these indirect pathways explained 85.6% of the total association.
• Perceived physical literacy was the strongest single mediator (42.4% of the total effect); peer support alone accounted for 17.6%, and the serial path (peer support → physical literacy) contributed 25.6%.
• Male students reported higher facility access and peer-support indicators than female students, though overall physical fitness and perceived physical literacy did not differ significantly by gender.

Introduction

Physical inactivity among adolescents and young adults remains a persistent public health challenge with measurable consequences for long-term health and healthcare systems. National surveys and international reviews document declining fitness and rising chronic risk factors in student populations. Governments and universities have responded with infrastructure investments and policy reforms aimed at expanding access to sport and mandating more regular exercise in school schedules. Yet infrastructure and policy changes do not automatically translate into sustained improvements in fitness. How students perceive the environment around them, the social support they receive from peers, and their own confidence and knowledge about movement—summed up as perceived physical literacy—appear to shape whether institutional resources yield measurable fitness gains.

A prospective multi-university study conducted in Hubei Province, China, tracked 1,165 undergraduates to test an integrated model linking perceived campus sports environment (access, institutional support, curriculum, teacher guidance) to objectively measured physical fitness one semester later. The research evaluated whether peer support and perceived physical literacy sequentially mediate that association and examined gender differences across key variables. The findings reveal that the campus sports environment matters — but primarily through social and cognitive pathways. This article synthesizes the methods and results, interprets their implications for campus sport policy and program design, and offers practical steps universities can take to convert facility investments into sustained improvements in student fitness.

Study design and measures: tracking perception to performance

The study used a two-wave prospective observational design with baseline (T1) self-reports of the psychosocial and environmental variables and follow-up (T2) objective fitness measurements collected from routine university assessments. Participants were 1,165 non-physical-education undergraduates (56.3% female; mean age 19.1 years) drawn from five universities in Hubei Province. Data collection took place between May and November 2024.

Key measures

• Perceived campus sports environment: A revised 17-item scale assessed students’ subjective evaluations across four domains—curriculum structure, teacher guidance, institutional support, and facility access. High internal consistency (overall Cronbach’s α = 0.912) and acceptable confirmatory factor analysis indices supported the scale’s construct validity.
• Peer support: A brief three-item composite captured activity-related peer modeling, co-participation and encouragement. Items loaded strongly on a single factor and showed adequate internal consistency (α = 0.867). The measure was treated as a pragmatic indicator of activity-related peer support rather than a full multidimensional construct.
• Perceived physical literacy: The nine-item Perceived Physical Literacy Instrument (PPLI) measured knowledge/understanding, self-expression/communication, and self-confidence, with good reliability (overall α = 0.894).
• Physical fitness: Objective fitness data followed the National Student Physical Fitness Standards (University Level) and included BMI, vital capacity, sprint, sit-and-reach, standing long jump, pull-ups (men) or 1-minute sit-ups (women), and a timed run (1,000 m for men; 800 m for women). Raw results were converted to sex-specific standardized item scores and combined into a composite score out of 100.

Analytic approach combined descriptive statistics, gender comparisons, bivariate correlations, and serial mediation modeling using the PROCESS macro (Model 6) with bias-corrected bootstrapping (5,000 resamples). Age and gender were included as covariates.

Strengths and constraints of the design Using objective, standardized fitness tests as the outcome is a major strength: it ties subjective perceptions to real performance metrics rather than relying solely on self-reported activity. A prospective element—collecting perceptions at T1 and fitness at T2—supports temporal sequencing, though key mediators were assessed concurrently at T1, so causal claims remain cautious. The sample size and inclusion of multiple universities also strengthen the study’s internal precision, while convenience sampling and regional focus limit generalizability.

What the data reveal: correlations, gender differences, and effect sizes

Correlations and descriptive contrasts illuminate how the campus environment, social context, and students’ self-perceptions relate to later fitness.

Bivariate relationships

• Perceived campus sports environment and physical fitness: r = 0.316 (medium)
• Peer support and physical fitness: r = 0.475 (medium-to-large)
• Perceived physical literacy and physical fitness: r = 0.662 (large)

Each domain of perceived campus sports environment (curriculum, teacher guidance, institutional support, facility access) showed positive associations with fitness; the composite perceived physical literacy indicator showed the largest association.

Gender contrasts Male students reported modestly higher scores than female students on facility access (Cohen’s d = 0.13) and all three peer-support items (d = 0.16, 0.14, and 0.19 respectively). Effect sizes were small but statistically significant. No significant gender differences were observed in perceived physical literacy or overall physical fitness scores. These patterns echo international findings: men often report greater facility use and social encouragement for vigorous activity, while gendered preferences, perceived safety, and comfort influence engagement patterns for women.

Interpretation of the numerical patterns Perceived physical literacy’s strong association with fitness suggests that students who feel knowledgeable, confident and socially competent in exercise settings tend to perform better on objective fitness measures. Peer support showed a robust bivariate link as well, consistent with evidence that exercising with friends and receiving encouragement raises both the frequency and persistence of physical activity behavior. Facility access and institutional support mattered, but their association with fitness weakened once psychosocial mediators were introduced into multivariate models—indicating that perceptions of environment exert influence primarily by shaping social interactions and individual capacities.

Untangling the mechanism: peer support and perceived physical literacy as mediators

A core contribution of the study lies in modeling a chained mediation process: perceived campus sports environment → peer support → perceived physical literacy → physical fitness. The serial mediation framework tests whether a favorable environment fosters peer activity norms and encouragement, which then bolster students’ perceived literacy and, in turn, improve fitness outcomes.

Key findings from the mediation models

• The total effect of perceived campus sports environment on later physical fitness equalled 6.063 units (on the standardized composite scale).
• The total indirect effect via the three mediation routes equalled 5.191, accounting for 85.62% of the total effect.
• Indirect effects partitioned as:
  • Peer support alone: effect = 1.066 (17.58% of total)
  • Perceived physical literacy alone: effect = 2.572 (42.42% of total)
  • Serial path (peer support → physical literacy): effect = 1.552 (25.60% of total)
• After inclusion of the mediators, the direct association between perceived environment and fitness dropped to non-significance (β = 0.045), consistent with the idea that the environment works predominantly through social and capacity-building channels.

Mechanistic interpretation A favorable sports environment—good facilities, supportive policies, inclusive curricula and engaging instructors—creates opportunities for students to gather, learn, and practice. Those opportunities increase the likelihood of peer co-participation, modeling and encouragement. Peers who are active can serve as role models, stimulate shared routines, and offer emotional encouragement that raises motivation and exercise self-efficacy. Such social interactions also provide informal learning opportunities: peers exchange tips, demonstrate techniques, and normalize regular activity, all of which can increase a student’s perceived knowledge, confidence and communication skills in exercise settings—components of perceived physical literacy. As perceived physical literacy increases, students become more likely to engage in moderate-to-vigorous physical activity with greater competence, translating into improved scores on standardized fitness tests.

Why the serial path matters The serial pathway’s contribution (25.6% of the total effect) underscores that peer support not only has a direct motivational role but also acts as a social learning mechanism that enhances perceived physical literacy. The social environment and individual capacity-building reinforce one another: peer-supported practice develops skills and confidence, while increased confidence sustains group-based and individual activity.

Why perceived physical literacy matters more than facilities alone

Investments in courts, gyms and equipment are necessary but not sufficient. The study identifies perceived physical literacy—the awareness, skills, social competence and confidence to be active—as the single strongest mediator linking environment to fitness. That suggests universities must pair material investment with deliberate educational and social strategies.

Components of perceived physical literacy

• Knowledge and understanding: knowing how to exercise safely and effectively, and understanding the health benefits.
• Self-expression and communication: being able to participate in group activities, communicate needs, and feel socially competent in sport settings.
• Sense of self and self-confidence: managing one’s own fitness, setting goals, and persisting through setbacks.

Real-world analogy: upgrading a campus gym without orientation or inclusive programming resembles building a library and leaving the books locked. Facilities offer resources; perceived physical literacy unlocks their use. A well-staffed fitness center with entry-level classes, buddy systems, instructional signage, and beginner-friendly programming turns infrastructure into sustained behavior change.

Evidence from other settings International studies show that interventions emphasizing skill acquisition and confidence—such as beginner-friendly classes, coach-led small group sessions, and peer-mentoring programs—produce larger increases in sustained activity than facility-only initiatives. Programs that teach basic movement competence, goal setting, and self-monitoring deliver downstream effects on both participation and fitness.

Translating evidence into campus practice: integrated strategies that work

The findings point to multi-component interventions. Universities should align infrastructure upgrades with actions that strengthen social connections and build students’ physical literacy.

Design principles

1. Pair facilities with structured social entry points
   • Create cohort-based fitness programs for first-year students (e.g., “Fitness Foundations” classes) that mix instruction with social bonding.
   • Schedule regular, campus-wide “sport socials” in which beginner workshops precede informal matches or group runs.
2. Embed physical literacy into curricula and extracurriculars
   • Integrate modules on exercise science, movement skills and self-management into general education or PE electives.
   • Offer micro-credentials for fitness competencies (e.g., “Cardio Basics,” “Strength Foundations”) that students can display on campus profiles.
3. Activate peer networks
   • Recruit and train peer leaders to run recreational clubs, lead group workouts and provide encouragement—these leaders act as credible role models and lower the social cost of joining.
   • Support student-designed activity groups that reflect diverse interests (dance, yoga, climbing, team sports) to increase perceived fit and comfort.
4. Make programming gender-responsive
   • Offer women-only sessions, flexible scheduling, and environments mindful of privacy and safety concerns.
   • Showcase female coaches and student leaders to normalize participation and provide visible role models.
5. Focus on beginner-friendly measurement and feedback
   • Provide simple, non-competitive fitness screening and goal-setting clinics that emphasize progress over performance.
   • Offer smartphone-based self-monitoring tools and campus leaderboards that encourage small wins and social recognition.
6. Monitor perceptions, not only inputs
   • Add periodic student surveys on perceived access, encouragement, and physical literacy to program evaluations. Students’ lived experience is an early indicator of whether investments translate into behavior.

Operational examples

• A university could launch a “Campus Move” initiative where renovated courts open with a six-week introductory series of skill clinics led by peer leaders and faculty coaches; participants complete a short perceived literacy module and receive personalized goals. The program integrates access, social support and literacy-building.
• Student unions can fund pop-up sports nights in underused spaces, accompanied by peer-led instruction and beginner-friendly formats—low-cost approaches that reduce barriers to entry.

Gender-sensitive considerations and inclusion strategies

The study found small but consistent gender differences: male students reported better perceived facility access and higher peer-support indicators. These differences, while modest, point to structural and cultural factors that can deter women from engaging fully.

Barriers that commonly affect female students

• Perceived safety and comfort in recreational spaces
• Limited scheduling flexibility that clashes with caregiving or work responsibilities
• Sports cultures that prioritize competitive, male-dominated activities
• Lower external encouragement from peers and family in some contexts

Actionable responses

• Audit campus spaces for lighting, privacy, and signage; reserve dedicated times for women-only or mixed-level sessions.
• Expand programming to include a broader variety of activities aligned with diverse preferences—dance, group fitness classes, walking programs, and mind-body modalities.
• Create targeted peer-support networks and mentorship programs for female students, pairing new participants with seasoned peers to lower social anxiety.
• Spotlight female athletes, trainers and student leaders in campus campaigns to shift norms and provide visible role models.

Policy alignment These local actions dovetail with national and institutional policies. For example, China’s Healthy China 2030 and the Sunshine Sports Movement emphasize both structural improvements and inclusive participation—making gender-responsive programming an appropriate complement to existing mandates.

How universities should evaluate success: indicators beyond turnout

Measuring the impact of campus sport initiatives requires tracking multiple indicators across levels—resources, perceptions, social connections and performance.

Suggested evaluation framework

• Structural metrics: facility availability hours, equipment counts, maintenance schedules.
• Participation metrics: attendance, retention in multi-week programs, diversity of activity types.
• Social metrics: peer co-participation rates, number of active peer leaders, qualitative measures of encouragement.
• Literacy metrics: pre-post assessments of perceived physical literacy (knowledge, confidence, communication).
• Performance metrics: standardized fitness testing (as used in this study), changes in MVPA frequency and duration.
• Perception metrics: periodic surveys on perceived facility access, institutional support, and safety.

Why perceptions matter An investment that increases facility hours but does not change student perceptions of accessibility, safety, or relevance may underperform. Perceptions are proximal indicators of whether the broader environment is experienced as enabling rather than merely present.

Limitations, uncertainties and next research steps

The study advances understanding of multi-level pathways but also highlights several methodological and conceptual limitations that future work should address.

Measurement and temporal ordering

• Predictors (perceived environment), mediators (peer support and perceived physical literacy), and covariates were assessed at the same baseline time point, while fitness was measured at follow-up. This design supports temporal precedence for the outcome but cannot definitively establish causal ordering among the psychosocial mediators. Multi-wave longitudinal or experimental designs are needed to test whether changes in peer support precede changes in perceived literacy or vice versa.

Self-report bias and scope of constructs

• Perceived physical literacy was measured with the PPLI, which captures knowledge, communication and confidence but not the full behavioral and motor competence spectrum. Peer support was measured with a brief three-item composite focused on activity-related interactions, which does not capture emotional, informational, or instrumental support comprehensively. Future studies should include multi-informant data, direct observation of peer networks, and objective measures of skill competence.

Generalizability

• Participants were drawn from five universities within a single Chinese province using convenience sampling. Cultural norms, institutional contexts and the strength of peer influence vary globally. Replication in other regions and cross-cultural comparisons would clarify the broader applicability of the serial mediation model.

Potential unmeasured confounders

• Socioeconomic background, parental education, pre-existing fitness, and health conditions may influence both perceptions and fitness outcomes. Future models should incorporate these variables to refine causal inference.

Exploring reciprocal and contextual moderation

• The current model is unidirectional. Reciprocal processes—where increasing fitness changes perceptions and peer dynamics—are plausible. Moderators such as sport type, urban versus rural campus, class year, and competitive sport culture may influence pathway strength. Experimental interventions can test whether augmenting peer support directly enhances perceived physical literacy and fitness.

Policy relevance and a roadmap for campus decision-makers

Policy-makers and university administrators assess programs across budgets, equity goals, and student success priorities. The study’s evidence suggests a calibrated approach: invest in facilities, but allocate comparable resources to social and pedagogical elements that shape how students experience those facilities.

A practical roadmap

1. Baseline assessment: survey students’ perceptions of sport environment, peer support, and physical literacy alongside objective fitness testing.
2. Targeted programming: launch pilot programs combining infrastructure access with peer-led groups and literacy modules; prioritize first-year cohorts and identified low-perception groups.
3. Scaling with evaluation: scale successful pilots using a stepped-wedge design to permit causal inference and cost-effectiveness analysis.
4. Continuous feedback loops: use student perception surveys as near-term indicators to iterate programming faster than waiting for annual fitness scores.
5. Equity checks: disaggregate outcomes by gender and other demographic factors to ensure inclusive benefits.

Cost-effectiveness perspective Relative to purely infrastructural projects, peer-led and literacy-focused interventions typically involve lower fixed costs and can increase utilization rates and long-term adherence. For universities working within constrained budgets, offering mixed-modality solutions—small grants for student clubs, peer-leader stipends, and targeted instructor training—will often yield high returns in student engagement and fitness outcomes.

Practical examples from campus practice

Three short case studies illustrate how the combined approach can be operationalized:

Case 1: Peer-led fitness communities A mid-sized university converts underused outdoor space into a “movement commons” and recruits student volunteers to run daily morning walks, lunchtime stretching sessions, and weekend intramurals. Peer leaders receive basic coaching and social facilitation training. Within one semester, participation doubles and perceived physical literacy scores rise among regular attendees.

Case 2: Credit-bearing physical literacy modules A university integrates a 2-credit “Foundations of Physical Literacy” elective into general education. The course pairs classroom modules on exercise science and goal setting with practical workshops and peer-coaching labs. Students report higher confidence in group sport settings and improved fitness test performance at semester’s end.

Case 3: Gender-responsive activity channels A campus launches women-only beginner circuits and a “female athletes’ showcase” highlighting student and staff women in sport. Attendance by female students increases and peer encouragement metrics show a measurable rise, narrowing the gender gap in social support indicators.

Each example combines environmental access, social activation, and literacy-building—reflecting pathways identified in the research.

Implications for national and institutional policy

Countries that target youth fitness at scale—such as through national strategies or school reform—should incorporate metrics of student perceptions and literacy into program evaluation. Counting courts and scheduling hours is necessary; tracking whether students actually feel supported, skilled and confident offers a more direct readout of program effectiveness.

At the institutional level:

• Include perceived environment and literacy items in annual student wellbeing surveys.
• Fund small-scale experiments that test combinations of facility access, peer activation and literacy curricula.
• Embed metrics of social support and literacy into performance indicators for campus sport offices, not solely usage statistics.

At the national level:

• Policies like China’s Healthy China 2030 and the Sunshine Sports Movement can emphasize implementation guidance on building social and educational supports alongside facility improvements.
• Funding streams could prioritize integrated proposals that demonstrate mechanisms to convert infrastructure into lifelong activity habits.

FAQ

Q: Does this study prove that improving campus facilities will boost student fitness? A: The study shows that students’ perceptions of the campus sports environment predict later fitness, but the environment’s effect operates mainly through peer support and perceived physical literacy. Facilities matter, but their impact is greater when they foster active peer networks and build students’ confidence and skills.

Q: What is “perceived physical literacy,” and how is it different from being physically fit? A: Perceived physical literacy refers to a person’s self-reported knowledge about exercise, social competence in activity settings, and confidence in managing fitness. It is a cognitive and affective capacity that supports ongoing engagement in physical activity. Physical fitness is measured performance—endurance, strength, flexibility—while perceived physical literacy is a capability and motivational resource that helps someone train and maintain activity.

Q: Why was peer support measured with only three items? A: The study used a brief, validated activity-related peer-support composite focusing on peer modeling, co-participation, and encouragement. That approach gives a practical indicator of social influences tied to activity behavior, though it does not capture the full multidimensional character of social support.

Q: Are the gender differences large and worrying? A: Differences were statistically significant but small in effect size. Male students reported slightly higher facility access and peer support. These differences may compound over time, so addressing them through inclusive programming is advisable.

Q: Can universities apply these findings in resource-limited settings? A: Yes. Peer-led initiatives, beginner-friendly classes, and short literacy modules are relatively low-cost interventions that can increase facility utilization and student engagement without major capital investments.

Q: What research would strengthen confidence in the causal pathways identified here? A: Multi-wave longitudinal research that measures perceptions, peer support, and physical literacy at separate time points would clarify temporal ordering. Randomized or quasi-experimental interventions that manipulate peer support or literacy programming while holding facilities constant would provide stronger causal evidence.

Q: How should program success be measured? A: Combine objective fitness measures with short-term indicators of perceived access, peer encouragement, and perceived physical literacy. Tracking participation diversity, retention, and equity across gender and demographic groups provides a fuller picture of impact.

Q: Will building physical literacy help students who already exercise regularly? A: Physical literacy programs typically benefit both beginners and active students by improving technique, injury prevention knowledge, social skills, and the ability to sustain varied activity across the lifespan. For already active students, literacy modules can refine performance and increase long-term adherence.

Q: Are these findings unique to China? A: The mediating roles of social support and perceived competence are consistent with socio-ecological research internationally. Cultural contexts shape the strength and form of peer influence, but the general mechanism—environment → social processes → individual capacity → fitness—has broad applicability.

Q: What immediate steps can a campus sport director take this semester? A: Start a small pilot that pairs extended facility hours with a peer-leader roster and a short “movement skills” workshop series. Collect pre-post measures on perceived access, peer support, and physical literacy to evaluate changes before scaling up.

The study underscores a central lesson for campus sport strategy: built assets provide opportunity, but social networks and students’ own sense of competence determine whether opportunity becomes sustained fitness. Policies and programs that align facilities, social incentives and literacy training produce the most consistent improvements in student fitness.
