Improvements of Shooting Performance in Adolescent Air Rifle Athletes After 6-Week Balance and Respiration Training Programs.

Context: Several factors, such as balance and respiration training programs, have been identified as contributing to a shooting performance. However, little is known about the benefits of these programs on the shooting records of adolescent air rifle athletes. Objective: The purpose of this study was to investigate whether balance and respiration training can contribute to the shooting performance required for adolescent air rifle shooting athletes. Design: Case-control study. Setting: Shooting range. Participants: A total of 21 adolescent air rifle athletes were recruited from the local school community and assigned to an experimental (n = 11; EG) or control (n = 10; CG) group. Intervention: The EG performed respiration and balance training for 30 minutes 3 times a week for 6 weeks, and the CG performed balance training only. Main Outcome Measures: Data were collected on the respiratory function, muscle activity, and shooting record before and after the 6-week intervention. Results: The forced vital capacity (FVC), forced expired volume in 1 second (FEV₁ ), FEV₁ as a percentage of FVC, peak expiratory flow, and maximum voluntary ventilation were significantly increased in the EG, and FEV₁ as a percentage of FVC was significantly increased in the CG (P < .05). The FVC and peak expiratory flow postintervention were significantly different between the groups (P< .05). The activity of the right internal oblique (IO) and left IO muscles of the FVC were significantly different in the EG (P < .05). Within-group changes in right external oblique, right 10, and left IO of the maximum voluntary ventilation were significantly increased in the EG (P< .05). The right IO and left IO activity improved more significantly in the EG than CG (P < .05). There was no difference between the groups with respect to the shooting records. Conclusions: The clinical significance of this study is the balance and respiration training affected the respiration function capacity and muscle activity, but did not affect the shooting record. Nevertheless, these training are a potential approach method to improve athletes' shooting record. [ABSTRACT FROM AUTHOR]
