“…They were divided into the two groups: normal group and FHP group. Because lung capacity and muscle activity differ between the genders 11 ) , results between the normal and FHP groups were compared separately for males and females. Before participation in this study, all subjects signed an informed consent document that was approved by the Institute Research Board of Kyungsung University.…”

[Purpose] This study investigated the effects of forward head posture on forced vital capacity and deep breathing. [Subjects] Twenty-six subjects, divided into the two groups (normal and forward head posture groups), participated in this study. [Methods] Forced vital capacity and forced expiratory volume in 1 second were measured using respiratory function instrumentation that met the American Thoracic Society’s recommendation for diagnostic spirometry. Accessory respiratory muscle activity during deep breathing was measured by electromyography. A Mann-Whitney test was used to compare the measure variables between the normal and forward head posture group. [Results] Forced vital capacity and forced expiratory volume in 1 second were significantly lower in the forward head posture group than in the normal group. Accessory respiratory muscle activity was also lower in the forward head posture group than in the normal group. In particular, the sternocleidomastoid and pectoralis major activity of the forward head posture group was significantly lower than that of normal group. Activities of the other muscles were generally decreased with forward head posture, but were not significantly different between the two groups. [Conclusion] These results indicate that forward head posture could reduce vital capacity, possibly because of weakness or disharmony of the accessory respiratory muscles.

“…In primary care of adults and children, spirometer-based pulmonary function tests can usefully be employed in clinical decision making, provided that testers are sufficiently trained and guidelines are accurately observed 7 , 8 ) . Pulmonary functions are generally measured in indoor environments, and depend on physical factors such as gender, body mass index, smoking history, and posture 9 , 10 ) . This study began from the hypothesis that changes in humidity alone might change pulmonary functions at rest (i.e., without performing any exercise).…”

[Purpose] The purpose of this study was to compare the effect of humidity changes on the values of pulmonary function at rest. [Subjects and Methods] This study was conducted with 30 young adults (9 males, 21 females; mean age 19.4 years). Participants’ mean height was 165.1 cm, and their mean weight was 60.2 kg. The experimental setting was a laboratory in which temperature was fixed at 25 °C. Using a humidifier, relative humidity was successively to adjusted 25%, 50%, and 90%, and pulmonary were measured functions at each level. Using a spirometer, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), expiratory reserve volume (ERV), and tidal volume (TV) were measured, and the results were compared and analyzed. [Results] Controlling for temperature, FVC and FEV1 showed statistically significant differences among different levels of relative humidity, but FEV1/FVC, TV, and ERV showed no significant difference. [Conclusion] In the case of exercises that require large respiration volumes, such as aerobic exercises or exercise load tests, it is recommended that higher than normal humidity levels should be maintained.

“…The proportion of obese adults in Korea increased rapidly from 26% in 1998 to 32% in 2012 2 ) , and decreased energy, fat intake, and lack of physical activity were associated with the increased in obesity 2 ) . Obese adults have a reduced quality of life and physical activity, and they have an increased frequency of cholecystectomy caused by gallstones, fecal incontinence, hypertension, sphincter muscle disturbance, diabetes, lung disease, infertility, hyperlipidemia, cardiovascular disease, osteoarthritis, respiratory function, and asthma 3 , 4 , 5 , 6 , 7 , 8 , 9 , 19 , 27 ) . Adults who are underweight and those who are severely obese (body mass index [BMI] > 35) have increased mortality 10 , 18 ) , thus obesity can be a life-threatening condition.…”

[Purpose] This study aimed to identify factors influencing the BMI classifications of 3,583 Korean adults using data from the fifth Korean National Health and Nutrition Examination Survey. [Subjects and Methods] Measures included lifestyle factors, physiologic factors, perceived health state, stress, subjective body recognition, health-related quality of life, and weight control behavior. [Results] Body perception scores were lower with underweight and higher with overweight and obesity than with a healthy weight. There was a lower proportion of underweight men and a higher proportion of overweight or obese men than women. Instances of Alcohol Use Identification Scores (AUDIT) ≥ 9 were proportionately lower with underweight and more with overweight or obesity relative to an AUDIT score < 9 with healthy weight. Hemoglobin A1c and systolic blood pressure were higher with obesity than with healthy weight. The total cholesterol level was greater with overweight and obesity than with healthy weight. [Conclusion] These results suggest that obesity intervention for adults should be based on age and sex and should include drinking habits and physical activity.
