  • This study investigated physical and physiological changes of normal young adults, who are cadets of the Air Force Academy, have kept long-term physical activities and healthy behavior. The physical and physiological indices were the blood and body composition. Data were collected at the first year period, and then 4th year period from same group of cadets. The amounts of blood components were not changed, but variation among cadets was significantly reduced in the 4th grade period. The red blood cells(RBCs) were significantly reduced and the concentration of hemoglobin(HGB) were significantly increased. The body weight was significantly decreased in the 1st grade period since the body fat was rapidly decreased after the basic military drill, and then it was recovered with building up of the skeletal muscle in the 4th grade period. Asymmetry of the arms was decreased with the increased physical activities and usage of various equipments. The muscular endurance were significantly enhanced in the 4th grade period. The long-term physical activities and healthy behaviors may keep the physical strength through enhanced blood stream and oxygen supply by reduction of the RBCs and increased HGB concentration, and fat and muscle control.

  • Purpose: The purpose of this study is to examine the effects of types of shoes and distance travelled on oxygen saturation and walk in relation to smoking. Methods: To achieve this goal, the researcher divided 20 normal male adults into two groups: a smoking group (10) and a non-smoking group (10) and used a treadmill to have them walk in intervals of 3 days, a total of 4 times. Results: By analyzing their walk, the following results were obtained: oxygen saturation showed statistically significant results in both the smoking group and the non-smoking group. The smoking group showed significant results for left pace and significant results were achieved for setting foot and shaking in both the smoking group and the non-smoking group. In comparison of oxygen saturation between groups, there were significant results for 3km sneakers walk and 3 km slippers walk. There were significant results for width in 3 km sneakers walk, left and right pace in 3 km slippers walk, and setting foot in 1 km sneakers walk. Conclusion: In conclusion, in the smoking group changes in walk occur if the shoes are more unstable and the distance travelled becomes longer.

  • Capsaicin. a vanillyl amide(8-methy1-N-vanilly1-6-nonenamide) with a molecular weight of 305.42, was substance, interrupting the pain conducting pathway Until recently the neurotoxic effects of Capsaicin to adult animals were thought to be limited to the peripheral nervous system. But several reports suggest the possibility of central nervous system changes after Capsaicin administration to the adult rat. Capsaicin desensitization is defined as long lasting, reversible suppression of sensory neuron activity. How fast and for how long the desensitization develops is related to the dose and time of exposure to Capsaicin, and the interval between consecutive dosing. In the long term Capsaicin treatment can lead to morphological degeneration and changes in some small sensory neurons, predominantly unmyelinated C fiber afferent nerve fibers. Clinical interest has recently been roused by evidence that Capsaicin's desensitizing action may be of therapeutic value and that an endogenous Capsaicin-1 ike substance may exist. This study summarizes the fundamental knowledge(mechanism, receptors, et al of Capsaicin) of Capsaicin for physical therapists.

  • Purpose: This study aimed to demonstrate reduction in stroke symptoms by analyzing the changes in respiratory function and activities of daily living (ADL) after respiratory muscle strengthening exercise in patients who had a stroke and thereby, propose an efficient exercise method. Methods: Twenty patients with hemiplegic stroke were divided into two groups, with 10 patients in each. The control group (CG) received the traditional exercise therapy, and the experimental group (EG) received the traditional exercise therapy combined with expiratory muscle strengthening training. The training continued for 6 weeks, 5 days a week. Forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) were measured with a spirometer, $SpO_2$ was measured with a pulse oximeter, and ADL were assessed by using the modified Barthel index (MBI). A paired t test was applied to compare the differences before and after the intervention, and an independent t test was used to compare the differences between the groups. The level of statistical significance was set as ${\alpha}=0.05$. Results: The changes in the FVC and FEV1 values within the group showed significant differences only in the EG (p<0.01). The between-group difference was statistically significant only for FVC and FEV1 in the EG (p<0.01). The changes in $SpO_2$ and MBI within the group showed significant differences only in the EG and CG (p<0.01). Between-group differences were statistically significant only for $SpO_2$ and MBI in the EG (p<0.05). Conclusion: The interventions with active patient involvement and combined breathing exercises had a positive impact on all the functions investigated in this study.

  • Purpose: This study examines the effects of elastic band of resistance exercise for balance control of the elderly. Methods: Thirty of eighty participants in experiment subjects who demonstrated balance-impairment through the use of primary screening tests including the one leg standing test (OLST), functional reach test (FRT) and timed up and go (TUG) were selected as subjects. Fifteen subjects that underwent muscle-strengthening exercise using an elastic band were selected as the exercise group and fifteen subjects were selected as a control group. Subjects undertook a home-based exercise program three times per week for 9 weeks. Muscle strength, functional assessment and a balance test were quantitatively measured before and after the exercise regimen. Results: After muscle strengthening exercises, changes in maximal voluntary isometric contraction (MVIC) showed a significant increase in all of the lower extremity muscles of the exercise group subjects. There were statistically significant differences between the exercise and control groups for changes in the OLST, FRT and TUG, which are functional assessments of balance ability, and changes of the unit path length and circumference area, measurement items of quantitative analysis. In addition, from examining correlations between MVIC, balance ability, it was found that an increase of muscle strength in the hip joint group of muscles among the lower extremity muscles had greater improvement in correlation with balance ability in this elderly population. Conclusion: Resistance exercise using elastic bands had significant effects on muscle strengthening in elderly subjects, with a resultant increase of lower extremity muscle strength with significant improvement of balance ability.

  • Objective: The purpose of this study was to determine the effect of upper extremity coordination exercise (UECE) during standing on the paretic side on balance, gait ability and activities of daily living (ADL) in persons with stroke. Design: A randomized controlled trial. Methods: A total of 27 patients with hemiplegic diagnosis after stroke were divided into two groups. Fourteen patients were in the study group and 13 patients were in the control group. The study group received conventional physical therapy and UECE during standing on the paretic side. The control group received conventional physical therapy and simple upper extremity exercise (SUEE). Subjects in both groups were given upper extremity training for 30 minutes per day, five times a week for 4 weeks. Initial evaluation was performed before treatment and reevaluated 4 weeks later to compare the changes of balance, gait ability and ADL (Korean version of modified Barthel index, K-MBI). Results: Both groups showed a significant effect for balance, gait ability and ADL (p<0.05). In the Independent t-test, between both groups showed a significant effect for balance and gait ability except ADL (p<0.05). Conclusions: In this paper, we investigated the changes in balance, walking, and ADL through UECE. We found significant changes in the study group and the control group. Results of the present study indicated that UECE during standing on the paretic side for 4 weeks had an effect on balance, gait ability and ADL (K-MBI) in persons with hemiplegia after stroke.
