“…This was indicated by lower normalized reach distance in all directions and SEBT composite score after muscle were induced to fatigue. The results were consistent with that of earlier findings that reported fatigue caused deterioration of dynamic balance 12,37 ) . These results may be caused by the reduced function of the muscle as characterized by reduced muscle response to neural excitation 38 ) and reduced contraction activities of the muscles 39 ) that caused reduced in force exertion.…”

ABSTRACT. The objective of the study was to determine the effects of Kinesio taping (KT) in inhibiting fatigue and preserving dynamic balance. Male recreational athletes were recruited to participate in this study. Participants were blinded from the group assignment and divided into four groups (Group A; KT and fatigue, Group B; no tape and fatigue, Group C; KT and no fatigue and Group D; no tape and no fatigue) using sequentially opaque, sealed envelopes. Pre and post measurements of Modified Star Excursion Balance Test ( SEBT ) composite score and normalized reach distance were used to measure dynamic balance. Adapted Functional Agility Short Term Fatigue Protocol (FAST-FP) was used to induce fatigue. KT was applied to rectus femoris, biceps femoris and medial gastrocnemius of the dominant leg. There was a significant change in the SEBT composite score between groups over time (p<0.05) and in time effect (p<0.05). The main effect comparing the SEBT composite score between the group was not significant (p=0.16). Group A (90.10±9.40) and Group B (86.14±10.50) attained lower mean for SEBT composite score compared to Group C (97.30±10.83) and Group D (98.13±9.47) suggests that fatigue have a diminishing effect on dynamic balance. KT application inhibit the effects of fatigue and preserved lateral and posterior direction of SEBT. KT application may lower the risk for injuries in the lateral and posterior directions following fatigue induction. Key words: dynamic balance, fatigue, Kinesio Taping, Star Excursion Balance Test (SEBT) (Phys Ther Res 00: 00-00, 0000)A large volume of literature has reported the high prevalence of sport-related injuries worldwide [1][2][3] . The most common injury site is the lower limb, and 23%-67% accounted for the knee 1,2) . Fatigue has been found to increase the risk of injury 4) . Fatigue is defined as decreased ability of the muscle to contract and exert a force that develops gradually soon after the onset of the sustained physical activity 5,6) . One of the consequences of fatigue is that it reduces the skill-related physical fitness component such as balance 7 ) and agility 8 ) and strength 4,7 ) which consequently impaired sports performance 9) . Dynamic balance has been well established as a vital component of fitness among athletes such as gymnasts, footballer, golfer, ice-hockey players, rifle shooter and taekwondo practitioners 10,11) . It has been shown that possessing good dynamic balance not only reduces the risk of injuries 12 ) but would increase sports performance 10 ) . Unfortunately, these advantages may be limited after fatigue 12) . Dynamic balance is defined as the ability to maintain the stability of the center of mass during movement 13 ) . Biomechanical deviations of the lower extremity occur during movement of the center of mass away from the base of support 14) . Balance is gained by maintaining equilibrium in a gravitational field and the ability to react quickly yet efficiently manners toward destabilizing forces to regain stability via postural adjustments...

“…Resulting functional deficits include limited postural control, decreased maximal strength of the evertor muscles and prolonged muscle reaction time 84 104. Even after successful return to play, ongoing deficits in neuromuscular control may contribute to a higher risk of a recurrent injury 105. For example, individuals with a history of ankle sprain have greater fatigue-induced alterations of dynamic postural control 106 107.…”

Lateral ankle sprains (LASs) are the most prevalent musculoskeletal injury in physically active populations. They also have a high prevalence in the general population and pose a substantial healthcare burden. The recurrence rates of LASs are high, leading to a large percentage of patients with LAS developing chronic ankle instability. This chronicity is associated with decreased physical activity levels and quality of life and associates with increasing rates of post-traumatic ankle osteoarthritis, all of which generate financial costs that are larger than many have realised. The literature review that follows expands this paradigm and introduces emerging areas that should be prioritised for continued research, supporting a companion position statement paper that proposes recommendations for using this summary of information, and needs for specific future research.

Fatigue Effect on Linear Center of Pressure Measures during Gait in People with Flat Feet

BackgroundFlat foot, as one of the common foot deformities can affect gait biomechanics and risk of lower extremity injury. Fatigue, as a high load task, can also change biomechanical parameters of locomotion. Studying normal and flat footed individuals under high load tasks such as fatigue can elucidate their differences more easily.ObjectivesIn this study, center of pressure (CoP) changes were studied between individuals with flat and normal feet after fatigue. CoP is one of the important gait measures which can show various biomechanical behaviors of different foot shapes.MethodsSeventeen subjects with normal feet and 17 with flat feet walked across two force plates before and after a functional fatigue protocol. Standard deviation of CoP in mediolateral direction (SD of CoPx) and in anteroposterior direction (SD of CoPy), overall mean velocity of CoP and length of CoP construction line of both groups were analyzed. The values of SD of CoPy and length of CoP construction line were normalized to individual foot lengths prior to statistical analyses.ResultsThere were no significant between-subject effects for all CoP measures. The only significant finding was the within-subject effect for the SD of CoPy (P = 0.008) with a large effect size (partial eta squared = 0.21). Fatigue resulted in lower SD of CoPy in both groups.ConclusionsLower SD of CoPy indicates less fluctuation of CoPy and a probable less center of mass movement which could reduce the risk of injury. Furthermore, the similar fatigue response in both groups of individuals with normal and flat feet indicates a similar biomechanical behavior despite their different foot arch height.
