Interoceptive Awareness, Perceived Stress, and Physical Performance in Sport Sciences Students

6. Juli 2026 aktualisiert von: Assoc. Prof. Dr. Özgür EKEN, Inonu University

Examining the Relationships Between Interoceptive Awareness, Perceived Stress, and Physical Performance Indicators: The Moderator Role of Gender and Sport Type

This cross-sectional observational study examined the relationships between interoceptive awareness, perceived stress, state and trait anxiety, sleep quality, and physical performance indicators in university-level sport sciences students. A total of 85 undergraduate students (54 males, 31 females; mean age = 20.65 ± 2.43 years) from the Faculty of Sport Sciences at Inonu University participated. Participants completed self-report measures (MAIA-2, PSS-10, STAI, PSQI) and a physical performance battery including handgrip strength, countermovement jump, sit-and-reach flexibility, and Y-Balance test. The study also investigated the moderator role of gender and sport type (team vs. individual) in these relationships, and tested the parallel mediating roles of perceived stress, trait anxiety, and sleep quality using PROCESS Model 4 with 5,000 bootstrap resamples.

Detaillierte Beschreibung

Background: Interoceptive awareness - the perception, interpretation, and regulation of internal bodily signals - has emerged as a psychological resource relevant to sport performance and mental health. However, empirical evidence linking interoceptive awareness to objective physical performance outcomes in athletic populations remains limited, particularly regarding potential psychological mediators such as perceived stress, anxiety, and sleep quality.

Objectives: The primary objective of this study was to examine the direct and mediated relationships between interoceptive awareness and physical performance indicators in university sport sciences students. The secondary objectives were to investigate (a) the parallel mediating roles of perceived stress, trait anxiety, and sleep quality; and (b) the differences in study variables based on gender and sport type (team vs. individual).

Methods: This cross-sectional observational study included 85 undergraduate students (54 males, 31 females) enrolled at the Faculty of Sport Sciences, Inonu University. Data collection was conducted between May 11 and May 17, 2026. Psychological measures included the Multidimensional Assessment of Interoceptive Awareness (MAIA-2), the Perceived Stress Scale (PSS-10), the State-Trait Anxiety Inventory (STAI), and the Pittsburgh Sleep Quality Index (PSQI). Physical performance was assessed via handgrip strength (digital dynamometer), countermovement jump (My Jump 2 mobile application), sit-and-reach flexibility, and Y-Balance test (composite score). Statistical analyses included Pearson correlation, independent samples t-tests, hierarchical multiple regression, and parallel multiple mediation analysis (Hayes PROCESS Model 4; 5,000 bootstrap resamples).

Expected Outcomes: The study aims to clarify whether interoceptive awareness contributes to physical performance directly or indirectly through psychological mediators, and to determine whether such relationships are moderated by demographic and sport-related factors.

Studienpopulation

Undergraduate students enrolled at the Faculty of Sport Sciences, Inonu University, Malatya, Turkey. The sample comprised 85 participants (54 males, 31 females; mean age = 20.65 ± 2.43 years) with diverse sport backgrounds, including team-sport athletes (n = 44), individual-sport athletes (n = 32), and students not actively participating in a specific sport branch (n = 9). Participants were recruited via convenience sampling during the Spring 2026 semester.

Intervention / Behandlung
Sport Sciences Students
Undergraduate students enrolled at the Faculty of Sport Sciences, Inonu University. Participants included both team-sport athletes (n = 44) and individual-sport athletes (n = 32), with an additional 9 participants who did not report an active sport branch. Mean age was 20.65 ± 2.43 years (54 males, 31 females).
Participants completed a battery of self-report psychological measures (MAIA-2, PSS-10, STAI State-Trait, PSQI) followed by a standardized physical performance testing session including handgrip strength (digital dynamometer), countermovement jump (My Jump 2 mobile application), sit-and-reach flexibility test, and Y-Balance test. All assessments were conducted in a single 45-minute session per participant.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Interoceptive Awareness - MAIA-2 Total Score
Zeitfenster: Single measurement at baseline (cross-sectional)
Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2) total score. The MAIA-2 is a 37-item self-report questionnaire assessing eight dimensions of interoceptive awareness (Noticing, Not-Distracting, Not-Worrying, Attention Regulation, Emotional Awareness, Self-Regulation, Body Listening, Trusting). Higher scores indicate greater interoceptive awareness. Total score is calculated as the mean of all 37 items (range: 0-5).
Single measurement at baseline (cross-sectional)
Handgrip Strength
Zeitfenster: Single measurement at baseline (cross-sectional)
Maximal handgrip strength (kg) measured using a digital hand dynamometer (Baseline Model 12-0286). Participants performed three trials with the dominant hand in a standing position with the elbow in full extension. The highest of three trials was recorded, with 30-second rest between trials.
Single measurement at baseline (cross-sectional)
Sit-and-Reach Flexibility
Zeitfenster: Single measurement at baseline (cross-sectional)
Dynamic balance and neuromuscular control assessed using the Y-Balance Test. Participants reached in anterior, posteromedial, and posterolateral directions while standing on one leg. Composite scores (%) were calculated for both right and left legs, normalized to leg length.
Single measurement at baseline (cross-sectional)
Countermovement Jump Height
Zeitfenster: Single measurement at baseline (cross-sectional)
Vertical jump height (cm) assessed using the My Jump 2 mobile application, a validated iPhone-based tool for measuring jump performance. Participants performed three maximal countermovement jumps with hands on hips and knee flexion of approximately 90°. The highest value was recorded, with 60-second rest between trials.
Single measurement at baseline (cross-sectional)
Y-Balance Test Composite Score
Zeitfenster: Single measurement at baseline (cross-sectional)
Dynamic balance and neuromuscular control assessed using the Y-Balance Test. Participants reached in anterior, posteromedial, and posterolateral directions while standing on one leg. Composite scores (%) were calculated for both right and left legs, normalized to leg length.
