Pistol Shooting Performance Correlates with Respiratory Muscle Strength and Pulmonary Function in Police Cadets

Abstract

Breathing patterns play a crucial role in shooting performance; however, little is known about the respiratory muscle strength and pulmonary capacities that control these patterns. The present study aimed to examine the relationship between shooting performance, respiratory muscle strength, and pulmonary function and to determine differences in respiratory capacities according to the shooting performance categories in police cadets. One hundred sixty-seven police cadets were recruited to assess respiratory muscle strength, pulmonary function, and shooting performance in a well-controlled environment. Measurements included maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), slow vital capacity (SVC), maximal voluntary ventilation (MVV), and pistol shooting scores. The shooting score had a moderate positive correlation with MIP (ρ = 0.33) and MEP (ρ = 0.45). FVC (ρ = 0.25), FEV1 (ρ = 0.26), SVC (ρ = 0.26) (p < 0.001) and MVV (ρ = 0.21) (p < 0.05) were slightly correlated with shooting score. There were differences between shooting performance categories in MIP, MEP, FVC, FEV1, SVC, and MVV (p < 0.001, p < 0.05). The results imply that both strong respiratory muscles and optimal pulmonary function may be one of the necessary prerequisites for superior shooting performance in police.

The effects of kettlebell training versus resistance training using the own body mass on physical fitness and physiological adaptations in obese adults: a randomized controlled trial

“…The respiratory parameters were measured using the CSMI Spirometrics instrument (Scott Medical, Antrim, Northern Ireland). This test sought to capture the maximum air volume that is expired after a forceful, rapid, and deep expiration, the forced vital capacity (FVC), and was recorded in liters [ 3 ].…”

“…Obesity rates have risen progressively over the last few decades and are currently at record-high levels, irrespective of age, sex, race, and smoking status [ 1 ]. The obesity pandemic is particularly severe in developing nations [ 1 , 2 ], and is considered a disease consisting of multiple aetiologies (i.e., genetics and psychosocial factors) [ 3 ].…”

“…Three measurements were taken at the five-minute interval, and the highest score was recorded. This is the enormous volume of air exhaled during a forceful, quick, and profound expiration [32] forced vital capacity was reported in litres.…”

Identification of Hand Tremor Levels in Shooting Activities Under Different Shooting Positions Using a Low Cost and Portable System

“…The next factor, breathing, is a proper breathing technique (inhale, pause, and exhale) that may keep a stable muzzle condition while shooting. It means that the breathing stage alters the body movement and stance, which affects the shooting aim and shooting accuracy 9 . The next factor is the grip position, a condition about griping the firearm perfectly.…”
