The purpose of this study was to investigate the effects of active vibration exercise of upper limb on physical capacity index (endurance, grip strength, balance, and flexibility) and vasomotor index (capillary length and body surface temperature) in middle aged women. 20 participants randomly divided into two groups: vibro-swing exercise (VSE) and non vibro-swing exercise (NVSE). Subjects in each group measured the 30 second arm curl test, hand dynamometer, one leg standing test, back scratch test, nail fold capillary microscope (NFM), and digital infrared thermal imaging (DITI) before and after exercise. The results showed that active vibration exercise of upper limb with vibro-swing equipment increased the endurance, balance ability, and the capillary length. In addition, changes in body temperature immediately after exercise were predicted to affect vasomotor. Active vibration exercise of upper limb has the advantage of being able to exercise anywhere regardless of the location by inducing different frequency changes in movement of various ranges and velocity. For this reason, the combination of vibration and active movement can be expected the physiological effects when producing exercise programs for middle aged women.

Obesity has been directly associated with the development of hypertension and cardiovascular disease. The purpose of this study was to investigate the blood pressure response during graded exercise test in obese adults. 189 subjects (age: $47.96{\pm}10.23$) were assigned to two groups: non-obese group (N=105, BMI: $22.05{\pm}1.57$, waist circumference: $76.90{\pm}6.17$) and obese group (N=84, BMI: $26.96{\pm}2.51$, waist circumference: $88.29{\pm}6.41$). The subjects underwent health screening and exercise treadmill test from January 2012 to December 2014. Graded exercise test was performed according to the Bruce protocol. Exercise duration (P=0.046) and METs (P=0.015) were significantly lower in obese group than non-obese group. There was no difference in the rate of change in blood pressure response between obese group and non-obese group during exercise, and the recovery rate of systolic blood pressure was delayed in the obese group compared to non-obese group in the first recovery period (P=0.020). The significant factors of increasing rate of change in maximum systolic blood pressure was waist (P=0.046) and hip circumference (P=0.008). In conclusion, these results demonstrate that, for hypertension prevention in obese adults, waist and hip circumference levels should be managed within normal range.

Objective: The rehabilitation protocols for functional recovery have been emphasized after total knee arthroplasty, and Pilates is in the spotlight as a safe and easily modified exercise method. The purpose of this study was to investigate the effects of mat Pilates exercise on lower extremity function, postural balance, and walking in the individuals with total knee arthroplasty. Design: One group pretest-posttest design. Methods: Eighteen older women with unilateral total knee arthroplasty was recruited in the study. The subjects were evaluated on lower extremity function, postural balance, and walking before and after mat Pilates exercise. All subject performed one hour mat Pilates exercise, 3 times a week for 8 weeks. Mat Pilates exercises were focused on core stability and lower extremity strengthening and, more dynamic movements were added to increase the difficulty of movements every two weeks. The lower extremity function was measured using the Western Ontario and McMaster Osteoarthritis Index (WOMAC), knee joint position sense, and five times sit-to-stand test. Postural balance was assessed by single leg stance test, functional reach test, and timed up and go test. Walking was measured by OptoGait system to temporospatial parameter. Results: The lower extremity function, postural balance, and walking were significantly improved after mat Pilates exercise, except for five times sit-to-stand test (p<0.05). Conclusions: This study demonstrated that the mat Pilates exercise was a useful method to improve lower extremity function, postural balance, and walking in the older women with unilateral total knee arthroplasty.

To establish the protocol of a standardized exercise test for evaluating exercise intolerance and degree of fitness in Thoroughbred racehorses, we examined serum lactate concentrations related to exercise intensities using the high speed treadmill. Twelve clinically healthy Thoroughbred racehorses with or without previous training or racing history were assigned to two gorups, fit and unfit group, respectively. The protocol used for the standardized exercise test was consisted of two stages : stage of warm-up and that of acceleration. During the warm-up, the horses exercised 5 min at 1.8m/s and 3 min 3.4m/s without inclination. At the acceleration stage, exercise test was performed at 10% slope and the speed was increased from the initial 5m/s to the maximal speed which each tested horse could keep up with. The speed was increased with incremental steps of 1 m/s every minute. During the last 15 sec of each step, blood samples were collected for serum lactate determination. $V_{max}$(maximal treadmill speed which tested horses could keep up with) of the fit group ($10.93{\pm}0.33m/s$, mean${\pm}$SE, n = 6) was higher than that of the unfit group ($9.52{\pm}0.23m/s$, mean${\pm}$SE, n = 6). Serum lactate concentrations increased exponentially according to exercise intensities. $V_{La4}$(speed producing a serum lactate concentration of 4mmol/l) of the fit group, $6.45{\pm}0.26m/s$, was higher than that of the unfit group, $5.45{\pm}0.23m/s$. $La_{peak}$(peak plasma lactate concentration during the exercise test) was lower in the fit group ($20.34{\pm}1.62mmol/l$ at 1 min after maximal intensity exercise) than in the unfit group ($24.78{\pm}1.09mmol/l$ at 2 min after maximal exercise step). $t_{50%}$(time required for the recovery of lactate concentration to be one-half of $La_{peak}$ after maximal exercise) of the unfit group and the fit group were 40.0 and 18.0 min, respectively. Therefore, the protocol of the incremental standardized exercise test utilized in this study seems to be reliable for the assessment of fitness and exercise intolerance for the Thoroughbred racehorses.

Purpose: The study investigated the effect of combined balance exercise using visual feedback and balance pads in rehabilitation of chronic stroke patients. Methods: The participants were 30 patients diagnosed with stroke who met the study selection criteria. Participants were randomly divided into 3 groups of 10: a balance pad exercise (BPE) group, a visual feedback exercise (VFE) group, and a combined balance exercise (CBE) group. All three groups engaged in 30 minutes of exercise, 3 times per week, for 6 weeks. Results: Pre-test and post-test results were analyzed using the functional reach test (FRT), the Berg balance scale (BBS), the timed up & go test (TUG), and the Korean version of the activities-specific balance confidence (K-ABC) scale. The study yielded the following results. Pre- and post-program FRT measures showed significant differences between the BPE and CBE groups (p < 0.05). BBS, TUG, and K-ABC scores showed clear differences in all three groups. Secondly, the CBE group and the BPE group a differed significantly on the BBS before and after the 6-week program (p < 0.05). Finally, the CBE group and the VFE group differed significantly on the BBS before and after the 6-week program (p < 0.05). Conclusion: The study results indicate that combined balance exercise improves balance more effectively than the balance pad and visual feedback exercises. This finding should help to improve rehabilitation in the future.
