“…Given that no one has investigated the effects of military exercises on ankle and knee JPS, our results may be comparable with the results of investigations in the sport field. The same pattern of findings (increase in JPS errors) was obtained in other studies of the ankle [24][25][26] and knee joints. 5,23,27,28 In most of these studies, the authors applied local fatigue in the laboratory to produce local fatigue, which may cause dysfunction of muscle mechanoreceptors.…”

Context: The high incidence of lower limb injuries associated with physical exercises in military conscripts suggests that fatigue may be a risk factor for injuries. Researchers have hypothesized that lower limb injuries may be related to altered ankle and knee joint position sense (JPS) due to fatigue.Objective: To evaluate if military exercises could alter JPS and to examine the possible relation of JPS to future lower extremity injuries in military service.Design: Cohort study. Setting: Laboratory. Patients or Other Participants: A total of 50 male conscripts (age ¼ 21.4 6 2.3 years, height ¼ 174.5 6 6.4 cm, mass ¼ 73.1 6 6.3 kg) from a unique military base were recruited randomly.Main Outcome Measure(s): Participants performed 8 weeks of physical activities at the beginning of a military course. In the first part of the study, we instructed participants to recognize predetermined positions before and after military exercises so we could examine the effects of military exercise on JPS. The averages of the absolute error and the variable error of 3 trials were recorded. We collected data on the frequency of lower extremity injuries over 8 weeks. Next, the participants were divided into 2 groups: injured and uninjured. Separate 2 3 2 3 2 (group-by-time-by-joint) mixed-model analyses of variance were used to determine main effects and interactions of these factors for each JPS measure. In the second part of the study, we examined whether the effects of fatigue on JPS were related to the development of injury during an 8-week training program. We calculated Hedges effect sizes for JPS changes postexercise in each group and compared change scores between groups.Results: We found group-by-time interactions for all JPS variables (F range ¼ 2.86-4.05, P , .01). All participants showed increases in JPS errors postexercise (P , .01), but the injured group had greater changes for all the variables (P , .01).Conclusions: Military conscripts who sustained lower extremity injuries during an 8-week military exercise program had greater loss of JPS acuity than conscripts who did not sustain injuries. The changes in JPS found after 1 bout of exercise may have predictive ability for future musculoskeletal injuries.Key Words: fatigue, proprioception, lower extremity, muscles Key PointsAfter an 8-week military exercise program, the loss of joint position sense (JPS) acuity was greater in injured than in uninjured conscripts. The JPS changes were greater in the ankle than in the knee joint. Greater JPS changes postexercise might increase the risk of subsequent musculoskeletal injury during basic training.

“…Numerous studies investigated the effects of muscle fatigue on the ability to reproduce different positions or movements in pointing tasks. Muscle fatigue has been shown to impair repositioning accuracy of the knee, 1-7 ankle, 8,9 shoulder, [10][11][12][13][14] forearm [15][16][17][18] and elbow. 19,20 These studies have all used the measurement method of position sense or repositioning errors for the evaluation of sensorimotor control and changes in proprioception after muscle fatigue.…”

“…24,25 Existing data support a use for kinesiology taping in reducing edema and helping treat regional swelling 33,34 ; however, there is limited evidence to substantiate its positive impact on various musculoskeletal conditions [8][9][10] or its ability to act as an ergogenic aid. 17,18 Research demonstrates that, in a fatigued state, temporarily, muscle activation is reduced, 35 muscle reaction time is impaired, 36 proprioception declines, 37 and there is decreased postural control. 38,39 The hypothesis of this study was that kinesiology tape would help improve runner performance in a fatigued state by acting like a rubber band when placed on the anterior aspect of the lower limbs to help pull them forwards and aid skeletal muscle's elastic property.…”

Objective: The purpose of this study was to determine if elastic therapeutic tape placed on anterior lower limbs would affect stride and step length in fatigued runners' gait. Methods: Forty-two healthy participants were equally divided into a kinesiology tape group (Rocktape) and a no-tape control group. Participants in both groups underwent a baseline running gait test at 6 mph without tape. After this, participants engaged in an exhaustive lower body fatigue protocol until they reached maximal volitional exhaustion. Participants were then randomized to 1 of 2 interventions: (1) Experimental group, which had kinesiology tape placed under tension on the anterior aspect of their lower limbs bilaterally from the upper thigh to just below the patella, or (2) Control group, which did not receive taping. All participants then engaged in a similar 6-mph running gait postanalysis. Participant's gait was analyzed for 90 seconds during each test iteration. Researchers used a 2-way repeatedmeasures analysis of variance considering fatigue (prefatigue, postfatigue) and group (tape, no-tape) as subject factors. Results: After the fatigue protocol, the no-tape group demonstrated a significant decrease in step length of 14.2 mm (P = .041) and stride length of 29.4 mm (P = .043). The kinesiology tape group did not demonstrate a significant decline in these gait parameters. Conclusions: In this preliminary study, placing elastic therapeutic tape over the anterior lower limbs demonstrated short-term preservation of runner step length and stride length in a fatigued state.
