Objective: The purpose of this study was to investigate the effects of foam roller (FR) stretching, kinesiotaping (KT), and dynamic stretching (DS) on gait parameters after inducing muscle fatigue in the ankle joint. Design: Cross-sectional study. Methods: The subjects were thirty healthy young adults between the ages of 20 and 31 years at Baekseok University who voluntarily participated in this study. The participants were randomly assigned to either the FR group, KT group, or the DS group after inducing muscle fatigue of the ankle joint. Fatigue induction of the ankle joint muscles was performed by alternating a heel up and down exercise with the standing posture on the ground. The speed was maintained at 40 beats/minute using a metronome. Subsequently, the respective intervention was applied to each group. Gait parameters were measured before and after ankle muscle fatigue induction, and after intervention using the GAITRite system. One-way ANOVA was used to compare gait parameters among groups, while repeated measures ANOVA was used to compare gait parameters within each intervention group. Results: The FR group increased significantly in velocity, step length, and stride length except for cadence after intervention compared to after ankle muscle fatigue induction (p<0.01). Furthermore, the KT group showed significant increases in velocity, cadence, step length, and stride length after intervention, especially in cadence group (p<0.05). All intervention groups showed significant increases in stride length after intervention, especially the DS group (p<0.05). Conclusions: Therefore, we suggest that KT, FR, and DS can be an effective intervention on gait parameters when the ankle joint is unstable and injured.

문제 정의
The purpose of this study was to investigate the effects of FR, KT, and DS interventions on gait following ankle joint fatigue in young adults. This study showed that there was a significant increase in velocity of the FR and KT groups after intervention than after fatigue, within groups.
Thus, recent studies have not yet investigated gait parameters although FR, KT, and DS have been known to be effective on reducing ankle fatigue and instability. Therefore, this study aimed to investigate the effects of FR, KT, and DS on gait parameters after inducing calf muscle fatigue in healthy normal adults.
제안 방법
All subjects performed fatigue-induced tasks of the calf muscles after assessing the gait parameters using the GAITRite system (CIR Systems Inc., Sparta, NJ, USA). The induction of fatigue of the subjects was confirmed by the rating of perceived exertion (RPE) index, in which it was stopped at more than 17 points in the RPE.
Gait speed was performed at the subject’s comfortable walking speed within a distance of 10 m. Gait variables used in this study included velocity, stride length, step length, cadence, single support, and double support time.
In conclusion, this study, we investigated the effects of FR, KT, and DS on gait variables with induced ankle joint muscle fatigue. In the repeated measures within groups, the KT intervention was effective in increasing velocity, step length, stride length, and cadence for ankle fatigue, while the FR application was effective in improving all variables except for cadence.
Subjects were provided with sufficient explanations on the experimental procedures and had voluntary participated in this study. The exclusion criteria for the study subjects were muscle or nervous system lesions, weakness or pain in the calf muscles, ankle joint, or foot, and cognitive impairment. The subjects were randomly assigned to the experimental groups.
2b) software. The participants laid down and the length was measured from the anterior superior iliac spine to the medial epicondyle of the ankle prior to the assessment for inputting into the GAITRite software. The data of the gait variables were the mean values that were obtained from three repetitions.
This posture readily stretched the calf muscles, and subjects placed their foot on the opposite ankle to enhance stretching. The subjects lifted their heels 10 to 15 times per leg as one set, with five sets and a one-minute break per set (Figure 3) [20].
The subjects were allowed to make an inverted V shape by raising their hips upward from the push-up position through the extension of the elbows and knees. This posture readily stretched the calf muscles, and subjects placed their foot on the opposite ankle to enhance stretching.
대상 데이터
Kinesio Tape (2016; Nippon Sigmax Co. Ltd., Tokyo, Japan) was prepared in a Y-shape with 40 cm in length and 5 cm in width. The distal part the Y-shaped kinesio tape was attached to the heel sole with the subjects in prone position.
The subjects of this study were 30 young students (20 males, 10 females) attending Baekseok University in Cheonan, Chungcheongnam-do. Subjects were provided with sufficient explanations on the experimental procedures and had voluntary participated in this study.
데이터처리
The homogeneity among groups was tested using the one-way ANOVA. One-way ANOVA was used to compare the means of gait variables among groups. The Bonfferoni was used for post-hoc analysis.
Repeated measures ANOVA was used to compare the means of gait variables within the groups (p<0.05).

성능/효과
In conclusion, this study, we investigated the effects of FR, KT, and DS on gait variables with induced ankle joint muscle fatigue. In the repeated measures within groups, the KT intervention was effective in increasing velocity, step length, stride length, and cadence for ankle fatigue, while the FR application was effective in improving all variables except for cadence. In particular, the KT was the most effective in improving cadence for ankle fatigue among groups.
It is considered that although DS increased significantly in stride length, repeated measurements weren’t statistically significant.
, Sparta, NJ, USA). The induction of fatigue of the subjects was confirmed by the rating of perceived exertion (RPE) index, in which it was stopped at more than 17 points in the RPE. Each group (FR, KT, and DS) consisted of ten randomly assigned subjects.
There was no significant difference in double limb support of the taping and FR groups after intervention compared to post-fatigue conditions, but it was significantly decreased in the DS group after intervention compared to post-fatigue conditions (p<0.05) (Table 2).
The purpose of this study was to investigate the effects of FR, KT, and DS interventions on gait following ankle joint fatigue in young adults. This study showed that there was a significant increase in velocity of the FR and KT groups after intervention than after fatigue, within groups. There were significant increases in cadence after intervention than after fatigue within all of the three groups, especially in the KT group.
