Pilates for Sedentary Individuals

23 de junho de 2026 atualizado por: Rommanee Rojasavastera, Mahidol University

Efficacy of Pilates on Core Stability and Physical Fitness Among Sedentary Individuals

The global rise in physical inactivity represents an escalating public health crisis, with the proportion of insufficiently active adults projected to reach 35% by 2030. Office workers are at the highest risk due to prolonged occupational sitting; a lifestyle factor heavily linked to various musculoskeletal disorders. While maintaining an upright posture relies on the synergistic coordination of deep core muscles, extended sitting disrupts this muscular balance, leading to chronic postural decay. Although Pilates is proven to improve core muscle thickness, enhance physical fitness, and alleviate low back pain, existing literature shows high variability in training durations (ranging from 6 to 16 weeks) and lacks definitive conclusions regarding its long-term, residual effects post-intervention. Consequently, it remains unclear whether the benefits of Pilates can be sustained once the structured training stops. Therefore, this study aimed to investigate the efficacy of Pilates on core stability and physical fitness among sedentary individuals, providing insights into sustainable exercise interventions.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Muscle thickness
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
A handheld ultrasound device was used to measure trunk muscle thickness at rest and during contraction.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Muscle strength
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
A handheld dynamometer was used to measure trunk muscle strength. Participants were instructed to maintain a maximal voluntary contraction (MVC) for 5 seconds per trial, with a 30-second rest period between trials to minimize fatigue.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Muscle flexibility
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
The sit-and-reach test was used to measure lower back and hamstring flexibility. Participants completed static stretching for 5 minutes before assessment. During the assessment, participants sat with knees fully extended and feet hip-width apart against the sit-and-reach box. They then reached forward, using their fingertips to displace the sliding scale as far as possible in a single trial.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Muscle endurance
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
The McGill Core Endurance Test was used to measure trunk muscle endurance. Each test was conducted once, with the duration recorded using a digital stopwatch. Timing commenced once the participant achieved the standardized starting position and ceased when they could no longer maintain the required posture.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Proprioception
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Joint Repositioning Error (JRE) was measured under both eyes-open and eyes-closed conditions to assess proprioception. Participants began the assessment seated with their hips and knees flexed at 90°, feet positioned shoulder-width apart, and arms resting naturally at their sides. From this baseline, they were guided into a neutral reference position-defined by full trunk extension and a flat spinal alignment-which they were instructed to memorize. To facilitate measurement, a marker was placed at the first sacral vertebra (S1), and a laser pointer was fixed 50 cm away from this landmark. The testing procedure required participants to perform three cycles of trunk flexion and extension before attempting to return to the neutral reference position as accurately as possible. The JRE represented the distance between the laser beam's initial and final positions.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Balance
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
The Y-Balance Test (YBT) was used to measure dynamic balance. Participants were instructed to reach out and push the indicator as far as possible.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.

Medida de resultado
Descrição da medida
Prazo
Posture
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Posture was measured using the Posture-analyzing and Virtual Reconstructing (PAViR) system, which utilized an RGB-D camera for skeletal reconstruction.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Pain level
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Pain location was identified through participant interviews, while pain intensity was quantified using a 0-10 Visual Analogue Scale (VAS).
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Health-Related Quality of Life
Prazo: Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
Health-Related Quality of Life was measured using the Thai version of the World Health Organization Quality of Life Brief (WHOQOL-BREF-THAI). This 26-item instrument assessed four core domains: physical health, psychological health, social relationships, and environment. Responses were scored on a Likert scale, with higher scores indicating better health status and overall QoL.
Baseline, at 4 weeks post-training, at 8 weeks post-training, at 2 weeks post-training cessation, and at 4 weeks post-training cessation.
