[Purpose] The purpose of this study is to examine the effect of calf muscle massage on ankle flexibility and balance. [Subjects and Methods] The study’s subjects were 32 healthy college students, divided into two groups according to the massage methods applied. Both groups received five-minutes of massage to each calf, making a total of ten minutes. Massage group A received effleurage, tapotement and pressure, and massage group B received effleurage, friction and petrissage. The functional reaching test and the modified one leg standing test were performed to measure the flexibility and balance of the ankles both before and after the massage application. [Results] In the functional reaching test performed after the calf muscle massage intervention, both groups showed significant increases. However, no significant differences were found between the two groups. In the modified one leg standing test, massage group A showed a significant increase in flexibility and balance after the intervention only when the left foot was used for support. Massage group B showed a significant increase when each foot was used for support. A significant difference between the groups was only observed only when the left foot was used for support. [Conclusion] Calf muscle massage may be effective for enhancing the flexibility and balance function of the ankle joint. In particular, a combined application of friction and petrissage massage techniques may be more effective for increasing ankle joint flexibility. Therefore, the application of calf massage can be considered an appropriate method for improving balancing ability.

[Purpose] This study examined the muscle activation when subjects gripped a handle with a circumference equal to 0%, 25%, 50%, 75%, or 100% of their hand length to determine the size that can be gripped most stably relative to the hand length. [Subjects and Methods] The muscle activation of 34 subjects was measured using electromyography. To make a cylinder proportionate to the hand length, multiple pencils were combined and the circumference was measured with a tape measure. The cylinders were made with circumferences of 0 %, 25 %, 50 %, 75 %, and 100 % of the hand length. [Results] The largest muscle activation was observed at handle circumferences of 50% and 75% of the hand length in the wrist extensor bundle and at 75% of the hand length in the flexor digitorum superficialis. [Conclusion] Therefore, circumferences of the middle range of hand length seems to be most appropriate for hammer handles and handles with high resistance which require large strength at industrial sites.

[Purpose] This study analyzed the activities of the back and hip muscles during Pilates exercises conducted in a prone position. [Subjects] The subjects were 18 healthy women volunteers who had practiced at a Pilates center for more than three months. [Methods] The subjects performed three Pilates exercises. To examine muscle activity during the exercises, 8-channel surface electromyography (Noraxon USA, Inc., Scottsdale, AZ) was used. The surface electrodes were attached to the bilateral latissimus dorsi muscle, multifidus muscle, gluteus maximus, and semitendinous muscle. Three Pilates back exercises were compared: (1) double leg kick (DLK), (2) swimming (SW), and (3) leg beat (LB). Electrical muscle activation was normalized to maximal voluntary isometric contraction. Repeated measures analysis of variance was performed to assess the differences in activation levels among the exercises. [Results] The activity of the multifidus muscle was significantly high for the SW (52.3±11.0, 50.9±9.8) and LB exercises(51.8±12.8, 48.3±13.9) and the activity of the semitendinosus muscle was higher for the LB exercise (49.2±8.7, 52.9±9.3) than for the DLK and SW exercises. [Conclusion] These results may provide basic material for when Pilates exercises are performed in a prone position and may be useful information on clinical Pilates for rehabilitation programs.

[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. Maximal concentric knee extension and flexion at three angular velocities (60°/s, 120°/s, and 180°/s) were measured. [Results] A significant difference was found in peak torque and total work of the flexion at 120°/s and 180°/s, as well as in the average power of extension at 180°/s. [Conclusion] Though it is not the main therapy for muscle function in football athletes with injury, kinesio taping was an effective adjunct therapy.

[Purpose] The purpose of this study was to compare the effects of shoulder stabilization exercise and shoulder isometric resistance exercise on maximum voluntary isometric contraction (MVIC) rate of change of shoulder stabilization muscles and hand function. [Method] The subjects of this study were nineteen healthy adults who had no problems with their musculoskeletal system. Group I performed shoulder stabilization exercise with a ball for 30 minutes. Group II performed shoulder isometric resistance exercise without a ball for 30 minutes. Electromyography recorded the MVIC rate of change of the upper trapezius, lower trapezius and serratus anterior in a manual muscle testing position after each exercise. All subjects were assessed for hand function (power and dexterity) using a dynamometer, pinch gauge, grooved pegboard and Purdue pegboard. The EMG data was compared using the independent t-test. Hand function was compared using the independent t-test and the paired t-test. [Results] The results of study were as follows: the MVIC rate of change showed significant difference between the shoulder stabilization exercise group and the shoulder isometric resistance exercise group for the upper trapezius and serratus anterior. In the shoulder stabilization exercise group, power grip, pinch, grooved pegboard test and Purdue pegboard test results were significantly increased post-intervention. In the shoulder isometric resistance exercise group, pinch was significantly increased post-intervention, but the other test results showed no significant differences. [Conclusion] We conclude that shoulder stabilization exercise is more effective than shoulder isometric resistance exercise for shoulder stability and hand function.
