Epidemiology of injuries in elite Korean handball athletes: a prospective cohort study.

Background: The aim of this study is to report injury patterns associated with training activities of South Korean elite handball athletes.

Methods: We prospectively collected data (stratified by sex, handball position, and injury location) on site from elite handball athletes between January and December 2019 at the Korea Training Center, South Korea. We used χ tests and one-way analysis of variance to compare groups.

Differences in attention, hand dexterity, and lower extremity activities in the presence or absence of a time limit.

[Purpose] The purpose of this study was to investigate how a time limit affects day-to-day tasks such as attention, hand dexterity, and sit to standing and sitting activity. The grounds for using a time limit as a method of learning tasks related to daily living are examined based on the results of this investigation. [Subjects and Methods] The subjects consisted of 51 healthy college students (20 males and 31 females).

Effect of mat pilates exercise on postural alignment and body composition of middle-aged women.

[Purpose] This study attempted to examine whether Pilates is an effective exercise for improving the postural alignment and health of middle-aged women. [Subjects and Methods] The participants in this study were 36 middle-aged women (20 in the experimental group, 16 in the control group). The experimental group participated in Pilates exercise sessions three times a week for 12 weeks.

Cardiorespiratory endurance evaluation using heart rate analysis during ski simulator exercise and the Harvard step test in elementary school students.

[Purpose] Efficient management using exercise programs with various benefits should be provided by educational institutions for children in their growth phase. We analyzed the heart rates of children during ski simulator exercise and the Harvard step test to evaluate the cardiopulmonary endurance by calculating their post-exercise recovery rate. [Subjects and Methods] The subjects (n = 77) were categorized into a normal weight and an overweight/obesity group by body mass index.

Kinematic characteristics of the lower extremity during a simulated skiing exercise in healthy participants.

[Purpose] Currently, various simulators are produced and used for athlete's exercise, rehabilitation, and training. In this study, we analyzed the kinematic factors of sectional and total movements in healthy participants by providing group-dependent information during simulated exercise. [Subjects and Methods] Participants in this study included 26 male adults (non-experts and experts); experts held a certificate issued by the Korea Ski Instructors Association.

Effect of kinesio taping on the isokinetic muscle function in football athletes with a knee injury.

[Purpose] The purpose of this study was to determine the difference in isokinetic muscle function in football athletes with a knee injury with and without kinesio taping. [Subjects] The subjects for this study were 10 football athletes (males) with a knee injury. [Methods] Measurements were performed by using Cybex dynamometer under uniform motion before and after the application of kinesio tape to the quadriceps and hamstring muscle.

Analysis of the risk factors of musculoskeletal disease among dentists induced by work posture.

[Purpose] The purpose of this study was to ergonomically evaluate the work posture of dentists to examine their subsequent risk of developing musculoskeletal diseases. [Subjects and Methods] Scenes in which the three dentists performed procedures at their dental clinics were videotaped. The videotapes of the dentists' work postures were evaluated and analyzed by using the Rapid Upper Limb Assessment (RULA) and Quick Exposure Check (QEC).

Comparisons of social interaction and activities of daily living between long-term care facility and community-dwelling stroke patients.

[Purpose] This study was conducted to compare the correlation between social interaction and activities of daily living (ADL) between community-dwelling and long-term care facility stroke patients. [Subjects and Methods] The Subjects were 65 chronic stroke patients (32 facility-residing, 33 community-dwelling). The Evaluation Social Interaction (ESI) tool was used to evaluate social interaction and the Assessment of Motor and Process Skills (AMPS) measure was used to evaluate ADL.

Immediate effects of the activation of the affected lower limb on the balance and trunk mobility of hemiplegic stroke patients.

[Purpose] The purpose of this study was to determine the effects of the activation of the affected lower limb on balance and the trunk hemiplegic mobility of stroke patients. [Subjects] The gait group (GG) consisted of 6 subjects with hemiplegia and the non-gait group (NGG) consisted of 6 hemiplegic subjects. [Methods] The subjects in both groups were given foot facilitation training once for 30 min.

Changes in respiratory function following intermittent living in the upland environment and the lowland environment.

[Purpose] The purpose of this study is to examine the effects on respiratory function and oxygen saturation of intermittent life in the uplands at an altitude above sea level of approximately 850 m. [Subjects and Methods] The study subjects were on 100 female student subjects attending a university located in the uplands. The subjects' oxygen saturation, heart rates and respiratory functions were measured at the university, which has campuses both in the uplands and the lowlands.
