A Study on the Effects of Forest Therapy on Sarcopenia
Purpose: The goal of this study is to investigate the effects of an 8-week Forest Based Intervention program on muscle strength, physical performance, and psychological well-being in older women with sarcopenia.
Study Activities: Participants will take part in a structured program at the Caoling Shibi Forest Healing Base in Yunlin.
Duration: The program lasts for 8 weeks, with 2 sessions per week (16 sessions total). Each session is approximately 180 minutes.
Activities: The program includes forest trail walking, resistance training using elastic bands, stretching, and sensory activities such as aromatherapy and deep breathing.
Assessments: Researchers will measure muscle mass, handgrip strength, walking speed, and balance. Participants will also complete questionnaires regarding their mood, sleep quality, and quality of life. These assessments occur before the program, immediately after, and at a 2-month follow-up.
Goal: We hope to determine if combining structured exercise with the forest environment can effectively improve the health and quality of life for older women with sarcopenia.

Detailní popis
Background and Rationale: Sarcopenia is a common skeletal muscle disease in the elderly characterized by the loss of muscle mass, strength, and physical performance. While resistance training and nutrition are core management strategies, Forest Healing has been shown to reduce stress (cortisol), regulate the autonomic nervous system, and improve immune function. This study aims to validate a standardized "manualized" forest healing intervention for sarcopenia, utilizing a cross-border collaboration framework between Taiwan and South Korea.
Study Design: This is a single-arm, pre-post intervention study (quasi-experimental design). The study will recruit 36 women aged 55 or older who meet the AWGS 2025 criteria for sarcopenia (low handgrip strength and low skeletal muscle mass index).
Intervention Protocol: The intervention occurs at the Caoling Shibi Forest Healing Base (altitude 1,500-1,700m). Each 180-minute session includes:
Aerobic and Balance Training: Forest trail walking at a Rating of Perceived Exertion (RPE) of 12-13.
Resistance Training: Elastic band exercises for upper and lower limbs (3 sets of 8-10 repetitions) at RPE 9-13.
Core Forest Therapy: Sensory awareness, aromatherapy, and deep breathing to promote relaxation.
Psychological Promotion: Group interactions and experience sharing to enhance social connection and motivation.
Outcome Measures:
Primary Outcomes: Muscle strength (measured by handgrip dynamometer) and physical performance (Short Physical Performance Battery, SPPB).
Secondary Outcomes: Muscle mass (measured via BIA), health-related quality of life (SF-36), geriatric depression (SGDS), and sleep quality (PSQI).
Environmental Monitoring: The study will also quantify environmental factors, including phytoncide concentrations, negative ions, and thermal comfort indices (PMV, PPD) to explore the relationship between the environment and health outcomes.
Safety Protocol: To ensure participant safety in a mountain environment, the study has established a three-tier medical safety mechanism, including on-site first aid by certified instructors, local AED medical services, and an emergency medical "green channel" to National Taiwan University Hospital, Yunlin Branch.

Experimentální: Forest-Based Intervention Group
Participants will undergo an 8-week structured forest healing program (2 sessions/week, 16 sessions total) at the Caoling Shibi Forest Healing Base . Each 180-minute session, led by certified instructors, includes forest trail walking (aerobic/balance), elastic band resistance training, nature-based sensory immersion (forest therapy), and group psychological support. The intervention follows a standardized manual focused on improving muscle strength and physical function. |
An 8-week structured intervention (16 sessions total, 180 min each) conducted at the Caoling Shibi Forest Healing Base.
The program integrates physical exercise (forest trail walking and elastic band resistance training) with nature-based sensory immersion (aromatherapy, deep breathing, and nature awareness).
The intervention follows a manualized protocol led by certified instructors, specifically designed to improve muscle strength, physical function, and psychological well-being in older women.
