Improve Lung Function Through Boys' Natural Learning Course Singing Program (NLCSP) as a Singing Skill Habilitation.

Area of Science:

• Pulmonology
• Music Therapy
• Adolescent Health

Background:

• Pulmonary function is crucial for adolescent health and vocal performance.
• Alternative habilitation approaches are sought for improving lung capacity in young individuals.
• Singing programs may offer benefits for respiratory health.

Purpose of the Study:

• To evaluate the effectiveness of the Natural Learning Course Singing Program (NLCSP) as an alternative habilitation approach for adolescent pulmonary function.
• To assess the impact of NLCSP on key lung function indicators such as forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1).

Main Methods:

• A study involving 48 adolescents (ages 12-13) divided into a program group (NLCSP) and a control group (standard music education).
• The NLCSP intervention consisted of twice-weekly 45-minute sessions for 2 months (16 sessions total).
• Pulmonary function tests (FVC, FEV1) were conducted pre- and post-intervention, with adjustments for demographic factors.

Main Results:

• Both groups showed significant improvements in adjusted forced vital capacity (FVC).
• The NLCSP group demonstrated a significant improvement in adjusted forced expiratory volume in 1 second (FEV1), unlike the control group.
• Statistically significant differences in FEV1 and FVC were observed between the groups post-intervention.
• No significant changes were found in fundamental frequency (F0) or F0 song range in either group.

Conclusions:

• The Natural Learning Course Singing Program (NLCSP) is a viable and effective strategy for adolescent vocal training.
• NLCSP shows promise in improving specific aspects of pulmonary function in adolescents.
• Further research may explore the long-term effects and specific vocal range changes in different demographic subgroups.
