Purpose: This study seeks to determine the effect of a lower extremity strengthening exercise that uses proprioceptive neuromuscular facilitation (PNF) on the gait and balance ability of a stroke patient. Methods: In this case study, a lower extremity strengthening exercise that used PNF was performed by the subject for 30 minutes 4 times per week for a 4-week period alongside typical rehabilitation therapy. The lower extremity pattern used flexion-abduction-internal rotation with knee flexion, extension-abduction-internal rotation, bilateral leg extension pattern. The 10 m walk test and 6 minute walk test were used to assess gait ability. The Berg balance scale was used to assess balance ability. Results: After the intervention, the time for the 10 m walk test decreased by 5.72 sec, the distance for the 6 minute walk test decreased by 20 meters, and the score on the Berg balance scale improved by 7 points, which indicates the effectiveness of this therapy for stroke patients. Conclusion: The results of this study indicate that a lower extremity strengthening exercise using PNF can improve the gait ability and balance ability of stroke patients.

Objective: To identify the effect of unstable surface kettlebell exercises on muscle activity and balance in middle and high school baseball players. Design: Randomized controlled trial. Methods: The participants were 29 middle and high school baseball players (Unstable surface kettlebell exercises group, USKE: 15; Stable surface kettlebell exercise group, SSKE: 14). The players in the USKE group performed kettlebell exercises for 60 mins on a stable surface thrice a week for 6 weeks, and the return rack was solidified on a stable surface in the same way as the experimental group. Before and after the experiment, the participant's muscle activity of the tibialis anterior and soleus was measured. In addition, the participant's balance was evaluated by measuring the distance moved from the foot's center of pressure (COP). The paired t-test was used to compare groups before and after the experiment. The independent t-test was conducted to assess differences in the degree of change between the two groups before and after the experiment. Results: Compared to the SSKE group, the USKE group showed significant differences in the muscle activity of the tibialis anterior and soleus and the balance with the eyes open and closed. Conclusions: The players in the USKE group showed a significant difference in muscle activity and balance than in those in the SSKE group. Thus, effectively including an unstable surface in the kettlebell exercise program will help improve physical function in athletes and people with musculoskeletal disorders.

During the 5 years period(93-197) of Seoul racecourse Thoroughbred racing, 2i963 holies took an active part in Seoul Racecourse and 61,181 horses entered the racing.400 horses(305 : 1 time, 76 :2 times, 19 :3 times, total : 514 cases) had bled(EIPH) from their nostils after their races. Incidence of bleeding horses from the 21963 racehorses was 13.5%, and incidence of bleeding cases from the 61,181 horses was 0.84%. The average racing frequence (1.05 times/1 month) of bleeders was more than that(0.8 times/1 month) of total race-horses. There was tendency to higher incidence of bleeding at older in age, female in sex, England/ Ireland horses in origin, higher grade in performances heavier in body weight increased, larger in weight to be carried, mid or longer in racing distance, handicap race, spring in season. Relationship did not exist between bleeding and respiratory disease. These results suggested that frequent entering into the race should be controlled. And body weight regulation with conditioning is recommended far reducing incidence of EIPH. It is supposed to prevent bleeding that decrescent performance horses should not be entering long distance or handicap race.

Recently, IoT researches using sensor data based on embedded networks in various fields including healthcare and sports have been continuously attempted. This study analyzes golf ball mobility to support IoT application in golf sports field. Generally, since the difference in density occurs due to the condition of the inner material and the abnormal state at the time of the outer skin joining during the manufacturing of the golf ball, the weight of each subset is equal for any two points with the same radius in the sphere cannot be guaranteed. For this reason, the deflected weight of the sphere has the undesirable effect of hitting the ball in a direction in which the weight of the ball is heavy. In this study, it is assumed that there is a unique center of gravity of the ball, and even if the golf ball cannot be manufactured perfectly, it wants to establish the basic principle to accurately recognize or mark the putting line based on the center of gravity. In addition, it is evaluated how the mobility of the golf ball with a deviation from the center of gravity of the golf ball affects the progress path (or movement direction) and the moving distance (or carry distance) after the golfer hits. The basic model of the mobility of the golf ball can help the golfer exercise model and the correlation analysis. The basic model of the mobility of the golf ball can help the golfer exercise model and the correlation analysis.

The effect of a chronic programme of either low- or moderate-to-high-intensity treadmill running on the activation of the Extracellular-signal regulated protein kinase (ERK1/2), Phosphorylated ERK 1/2(pERK1/2) and the Phosphorylated c-Jun N-terminal kinase(pJNK) pathways was determined in rat Back skin Hair follicle. Sprague-Dawley rats were assigned to one of three groups: (i) sedentary group(NE; n=10); (ii) low-intensity exercise group (Bm/min; LIE; n=10); and (iii) moderate-high-intensity exercise group(28m1min; HIE; n=10). The training regimens were planned so that animals covered the same distance and had similar utilization for both LIE and HIE exercise sessions. The report runs as follows; A single bout of LIE or HIE following 4 weeks of exercise led to a twofold increase in the phosphorylation of ERK2, pERK2 and a threefold increase in pJNKl, pERKl. ERKI phosphorylation in LIE Back skin sampled and pJNK2 in HIE Back skin sampled 48h after the last exercise bout was similar to sedentary values, while pJNK2 phosphorylation in LIE Back skin sampled was 70-80% lower than sedentary. 48h after the last exercise bout of LIE or HIE increased ERK2, pERKl and pJNKl expression, with the magnitude of this increase being independent of prior exercise intensity or duration. PERK1/2, pJNKl expression was increased Three- to fourfold in Back skin Hair follicle sampled 48h after the last exercise bout irrespective of the prior exercise programme, but ERKI expression in HIE Back skin sampled was approximately 90% lower than sedentary values. In conclusion, exercise-training of different jntensities/durations results in selective postexercise activation of intracellular signal pathways, which may be one mechanism regulating specific adaptations induced by diverse training programmes.

Background: Scapular winging is a prominence of the entire scapular medial border, mainly caused by insufficient activity of the serratus anterior (SA) and imbalance of scapulothoracic muscles. Push-up plus (PUP) exercise has been commonly used to increase SA muscle activity. The facilitation of abdominal muscle may affect scapular muscle activity by myofascial connections. Thus, the sequential activation of the turnk muscles is suggested to facilitate the transition of proper force from upper limb and restore force couple of scapular muscles. The abdominal drawing-in maneuver (ADIM) has been effective in improving activation of the deep trunk muscles during movement. Objects: The aim of this study was to determine the effect of ADIM on the activity of the upper trapezius (UT), lower trapezius (LT), and SA during PUP exercises in subjects with scapular winging. Methods: Fourteen men with scapular winging (determined as a of distance between the scapular medial border and thoracic wall over 3 cm) volunteered for our study. The subjects performed the PUP exercise with and without ADIM. Surface electromyography was used to collect the electromyography data of the UT, LT, and SA. A scapulometer was used to measure the amount of scapular winging. Results: SA activity was significantly greater and scapular winging significantly lower during the PUP exercise with ADIM than during those without ADIM. Conclusion: PUP exercise with ADIM can be used as an beneficial method to improve SA activation and to reduce the amount of scapular winging in subjects with scapular winging.

Background: The purpose of this study was to investigate the effect of leg lift difference on serratus and upper trapezius when exercising in a scapula in a prone position, a typical waist stabilization exercise for subjects with a winged scapula. Method: Twenty normal adults and 20 subjects with winged scapula participated in the experiment. The surface EMG recordings were obtained from external oblique muscle and internal oblique muscle during scapula protraction exercise. The presence or absence of winging of the shoulder bone was measured using an electronic digital caliper for the distance the medial border of the scapula is lifted to the rear. In prostrate pier movement posture in both groups, both legs supporting, dominant leg lifting, and non-dominant leg lifting including the scapula protraction were conducted respectively. Results: In the results of comparison between the two groups, the dominant external oblique muscle and the non-dominant internal oblique muscle tended to increase according to the difference of the leg lifting of normal people. In the winged scapula group, internal oblique muscle showed increased muscle activity more than external oblique muscle. Conclusion: It was most effective to exercise with lifting the same position leg for strengthening the same external oblique muscle, and the opposite internal oblique muscle. Also, it is effective to exercise in prone pier movement posture for trunk stability. In addition, internal oblique muscle shows increased muscle activity in subjects with winged scapula. Therefore, appropriate adjustment of external oblique muscle and internal oblique muscle may have a positive effect on scapula dysfunction for trunk stability.

Purpose : Chronic ankle instability (CAI) can impair strength and balance, leading to activity limitations and restricted participation. Traditionally, ankle stabilization exercises have been applied, and more recently, the effects of hip muscle exercises have been studied. The purpose of this study was to determine the immediate effects of hip exercises (HE) and ankle stabilization exercises (ASE) on dynamic balance, performance and ankle function in subjects with CAI. We also compared the difference in effectiveness between HE and ASE. Methods : A total of 34 subjects with CAI participated, ane were randomly divided into two groups: the HE group and the ASE group. The HE group performed a program consisting of exercises above 70 % MVIC, while the ASE group performed a traditional ankle stabilization exercise program. The subjects in each group completed their respective exercise program for a total of 30 minutes once a day and were assessed before and after the intervention. Dynamic balance was assessed using the Y-balance test (YBT). Performance was assessed using the hop for distance test (HDT), and side-hop test (SHT). Ankle function was assessed using foot and ankle ability measure (FAAM) questionnaires. Results : YBT, HDT, and FAAM values increased significantly in both groups after the intervention (p<.05), and there was no significant difference between the groups. SHT values decreased significantly in both groups after the intervention (p<.05), and there was no significant difference between the groups. Conclusion : Although no significant superiority was observed between HE and ASE in this study, both exercise programs were effective in improving dynamic balance, performance, and ankle function in subjects with CAI. These findings suggest that both HE and ASE can be suitable interventions for CAI, highlighting the need for individualized treatment plans. Future research is warranted to explore the long-term effects of exercise programs on CAI subjects of different ages and occupational characteristics.
