OBJECTIVES The purpose of this study was to examine the effects of a rehabilitation exercise program after posterior cruciate ligament (PCL) reconstruction between genders.METHODS The research subjects were 22 patients who had posterior cruciate ligament reconstruction. They were divided into Male Group (n=11) and Female Group (n=11). The dependent variable was Lysholm knee score, IKDC (International Knee Document Committee) score, isokinetic muscle strength of knee joint, which it was measured Pre-Op (Previous Operation) and during the 24-week rehabilitation exercise program period, it was measured at Post-Op (Post Operation) 12 and Post-Op 24 weeks.RESULTS First, significant differences by period were noted on Lysholm knee score (p<.001) and IKDC score (p<.05). Second, isokinetic strength of knee joint extension in involved side is significant differences between genders (p<.01). Third, isokinetic strength of knee joint extension in involved side has significant differences by period (p<.01). Forth, isokinetic strength of knee joint extension in uninvolved side has significant differences between genders (p<.05). Fifth, isokinetic strength of knee joint flexion in uninvolved side has significant differences between genders (p<.01). Sixth, isokinetic strength of knee joint flexion in uninvolved side has significant differences by period (p<.05).CONCLUSIONS This paper confirmed that the effect of a rehabilitation exercise program on subjective function is not influenced by gender, but by period. On the other hand, the effect of a rehabilitation exercise program on strength is influenced by not only gender, but also period. That application of rehabilitation exercise program after posterior cruciate ligament reconstruction was significant difference between groups in male and female on isokinetic strength of knee joint and by period. Therefore, we suggest that a rehabilitation exercise program should be designed differently in proper way between male and female group.

OBJECTIVES The current study aimed to examine the existing literature carried out in Korea regarding physical activity and its related factors based on the social ecological model (SEM).METHODS A systematic search of relevant literature published from March 2011 to December 20200 was conducted through RISS, KISS, KCI, DBpia, and SEMANTIC SCHOLAR. A total of 9 studies met the inclusion criteria. The selected articles were all of high quality as assessed using the Mixed Methods Appraisal Tool.RESULTS Results indicated that all SEM constructs were significantly correlated with physical activity. In specific, self-efficacy showed highest correlation effect size with 0.41(95% CI=0.33~0.49), followed by pros with 0.26(95% CI=0.23~0.30), quality of exercise facilities with 0.25(95% CI=0.19~0.32), accessibility of exercise facilities with 0.23(95% CI=0.20~0.26), friend support with 0.21(95% CI=0.15~0.28), and family support with 0.20(95% CI=0.03~0.38).CONCLUSIONS The current study was the first attempt applying a meta-analysis to investigate the existing research publications targeted at Korean physical activity based on the SEM. More importantly, the study suggests the direction of evidence-based research by synthesizing studies that applied the SEM to physical activity conducted in Korea and providing practical data to establish strategies to promote physical activity based on the SEM in the future.

OBJECTIVES The purpose of this study was to investigate the force production patterns of individual muscles surrounding the knee during running (RUN) and cutting (CUT) tasks.METHODS Thirteen women (24.2±3.5 yrs, 162.8±6.0 cm, 55.3±6.2 kg) performed a series of running and cutting tasks. Running and cutting motions were recorded using a motion capture system and ground reaction force (GRF) was recorded using a force plate. Three-dimensional knee angle, ground reaction force, and knee joint moment were calculated using Visual3D software. OpenSim musculoskeletal modeling software was used to calculate the force of individual muscles including the medial hamstring, biceps femoris long head, biceps femoris short head, rectus femoris, vastus medialis, vastus lateralis, gastrocnemius medialis, and gastrocnemius lateralis. All data were analyzed for loading response (or weight acceptance), mid-stance, and final push-off periods, respectively and were compared between two tasks.RESULTS At loading response: external rotation angle, medial and vertical GRFs, and valgus moment for the CUT task were greater than those of the RUN task. Compared to the RUN task, the CUT task showed: 1) an increase in lateral hamstring muscle force at weight acceptance, 2) a decrease in hamstring muscle force and an increase in medial vastus muscle force at mid-stance, and 3) an increase in lateral gastrocnemius muscle force at final push-off.CONCLUSIONS Selective force production patterns of muscles surrounding the knee seem to offset the external load caused by the cutting motion. We anticipate that our results will provide basic data for future training programs designed to prevent noncontact knee injuries.
目的本研究的目的是调查在跑步(RUN)和切割(CUT)任务中单个膝盖周围肌肉的力量产生模式。方法13例女性(24.2±3.5岁，162.8±6.0 cm, 55.3±6.2 kg)进行跑步和切割任务。使用动作捕捉系统记录奔跑和切割动作，使用测力板记录地面反作用力(GRF)。利用Visual3D软件计算三维膝关节角度、地面反力和膝关节力矩。使用OpenSim肌肉骨骼建模软件计算单个肌肉的力，包括内侧腘绳肌、股二头肌长头、股二头肌短头、股直肌、股内侧肌、股外侧肌、腓肠肌内侧肌和腓肠肌外侧肌。所有数据分别分析了负载响应(或重量接受)、中间姿态和最终推离期，并在两个任务之间进行了比较。结果在加载响应方面，CUT任务的外旋角、内侧和垂直grf、外翻力矩均大于RUN任务。与RUN任务相比，CUT任务显示:1)负重接受时腘绳肌外侧力量增加，2)中站时腘绳肌力量减少，股内侧力量增加，3)最终推离时腓肠肌外侧力量增加。结论:膝关节周围肌肉的选择性力产生模式似乎抵消了切割运动引起的外部负荷。我们预计我们的研究结果将为未来的训练计划提供基础数据，以防止非接触性膝盖损伤。

OBJECTIVES To assess children’s physical and sedentary activity behavior, enjoyment (i.e., liking), and preference during two separate experimental conditions: parent attentive and parent non-attentive.METHODS Ten children (n = 6 boys, 4 girls), 3 to 6 years old, along with one parent (n = 6 mothers, 4 fathers) per child participated in each condition on separate days for 30-minutes in which they could choose from a variety of physical and/or sedentary activities.RESULTS A greater number of accelerometer counts (p = 0.04) were accumulated during the parent attentive (96,547 ± 33,075.26 counts) condition than the parent non-attentive (48,316.30 ± 46,101.47 counts) condition. More time (p = 0.007) was allocated to sedentary activities during the parent non-attentive (19.5 ± 13.3 minutes) condition than parent attentive (2.8 ± 3.55 minutes) condition. Children liked (p = 0.004) the parent attentive (9.05 ± 1.21 cm) condition more than parent non-attentive (4.42 ± 3.18 cm) condition. A non-significant (p = 0.21) proportion of children identified the parent attentive (70%) as their preferred condition over the parent non-attentive condition.CONCLUSIONS Parental attentiveness may be an important component to take into consideration when trying to maximize children’s physical activity behavior and enjoyment while simultaneously reducing sedentary behavior.

OBJECTIVES The purpose of this study was to analyze the effects of brief dry cupping on muscle soreness of the gastrocnemius muscle and range of motion (ROM) in the ankle.METHODS Thirty-six participants (age=29±10 yrs, ht=173.8±10.3 cm, wt=75.3±15.9 kg) were randomly assigned to three groups: A (no exercise), B (bilateral heel drops to exhaustion), and C (right unilateral heel drops to exhaustion). Dorsiflexion ROM was assessed bilaterally for all groups. All participants received the cupping protocol on the right gastrocnemius, but C also received it on the left. Dry cupping was applied using four two-inch cups in four quadrants on the calf for 90 seconds. Soreness was reported using a 10-point VAS scale at 24- and 48-hours. Repeated measures ANOVAs were used to examine the effects of cupping on soreness and range of motion, respectively. Alpha was set at 0.05 for all tests.RESULTS A significant difference in muscle soreness existed between right (3.58±1.31 VAS) and left (2.83±1.02 VAS) calves for group B at 24 hours (p = 0.029). No other significant differences existed between calves that were and were not cupped (p > 0.05). No significant differences in ROM occurred between any conditions (p > 0.05).CONCLUSION Ninety seconds of dry cupping on the calf may reduce 24-hr muscle soreness after performing heel drops to exhaustion, but has no effect on ROM.

OBJECTIVES Delayed onset muscle soreness (DOMS) is discomfort that occurs within 8-24hrs following an unaccustomed bout of physical activity that peaks within 24-27hrs and slowly resolves on its own. White willow bark (WWB) is a nutritional supplement that is believed to have anti-inflammatory and analgesic properties like aspirin but without the risk of GI adverse effects. The purpose of this investigation is to determine the effectiveness of WWB on alleviating the symptoms of DOMS following exercise.METHODS Twenty-five individuals volunteered to participate and were randomly assigned to take WWB (798mg salicin) or placebo for 5 days following a lower body resistance training session which consisted of 5X10 lunges at 40% body weight (BW) and 3X fatigue leg press at 75%BW. Test procedures included visual analog scale (VAS), mid-thigh circumference and pressure pain threshold. VAS was measured pre, all five days of the supplementation period and day 6 (post-supplementation). All other variables were measured at pre, immediate, day 3(72hrs), and day 6 (post-supplementation).RESULTS No condition X time interaction was observed (p > 0.05) for any variable. However, VAS scores were lower in the WWB compared to the placebo for all time frames. There was a significant main effect of time for VAS scores indicating muscle soreness for hamstrings (p < 0.001), gluteal (p < 0.001), gastrocnemius (p < 0.001) and quadriceps (p < 0.001). In addition, there was a significant main effect of time for right midthigh pressure pain threshold (p = 0.02), mid-right (p < 0.001) and mid-left (p < 0.001) thigh circumference.CONCLUSIONS WWB may reduce subjective feelings of muscle soreness and appears to have analgesic properties.

OBJECTIVES This study was to examine the effect of the 12-week video-based non-contact corrective exercise continuum (CEC) program on the forward head posture, central asymmetry, varus and valgus knees for men and women with postural imbalance.METHODS Subjects were recruited openly by the Internet community and measured their posture with a 3D whole body scanner (Medicube WS-210, Korea), and then classified into exercise group (n=32, EG) and control group (n=32, CG). Total subjects were classified into forward head posture exercise group (n=8), central asymmetry exercise group (n=8), varus exercise group (n=8), valgus exercise group and each control group (n=8). For the non-contact home training, 12 weeks of 30 minutes/day, 3 times/week, corrective exercise continuum were conducted. The CEC program is an effective treatment to correct the anatomical alignment of the extremities as suggested by the National Academy of Sports Medicine.RESULTS As a result, the distance between the centers according to the forward head posture CEC program in EG, the angle of spinal inclination of the cervical and thoracic vertebrae, and central asymmetry were lowered (p<.05). Body shape distribution balance and shoulder tilt angle were lowered in EG according to the central asymmetry CEC program (p <.05). According to the varus CEC program in EG, the distance between the center of the knee, the tilt angle of the femur and tibia, and body shape distribution were lowered (p <.05). According to the valgus CEC program in EG, the distance between the center of the knee increased, and the tilt angle of the femur and tibia decreased (p<.05).CONCLUSIONS The effect of improving the anterior head posture, central asymmetry, varus and valgus knees of postural imbalance according to the CEC program was confirmed. It is thought that the CEC program can restore optimal neuromuscular control by restoring proper joint kinematics and restore posture and balance by reducing the observed muscle tension.

OBJECTIVES This study aimed to investigate the effect of the Kinesio taping on ankle strength, Dynamic balance and, functional movement in wrestlers with chronic ankle instability.METHODS Twenty wrestlers who registered in the Korea Wrestling Association were participated in this study. They were divided into two groups (chronic ankle instability group [n=10] or control group [n=10]) based on Cumberland’s ankle instability questionnaire. Ankle strength (dorsiflexion, plantarflexion, inversion, and eversion) were measured using manual muscle tester, and the dynamic balance was measured using Y-Balance test (anterior, postero-medial, postero-lateral, and composite). Functional movement hop test (side hop, square hop, and figure-of-8 hop) were used to evaluate functional movement.RESULTS The significant interaction was observed between group and time on the Y-balance test (composite score), and functional movement hop test (figure-of-8 hop) (group × time, all P for interaction < 0.05).CONCLUSIONS These results suggest that Kinesio taping has a positive effect on dynamic balance and functional movement. Also, Kinesio taping may be able to use an alternative and effective methods to maintain ankle stability and performance in the wrestlers with chronic ankle instability.
