Kinesiology tape mediates soccer-simulated and local peroneal fatigue in soccer players

Effects of the direction of Kinesio taping on sensation and postural control before and after muscle fatigue in healthy athletes

In this study, Kinesio tape (KT) was applied in two different directions to the gastrocnemius muscle, the most important muscle in stance stability, to investigate the effect of different taping directions on overall balance and sensation systems before versus after muscle fatigue. The participants, comprising 45 healthy athletes, were randomly divided into three groups: the placebo taping group (PTG), the facilitation KT group (FKTG), and the inhibition KT group (IKTG). The tests involved in this study were a balance test, a superficial sensory function test, and a combined cortical sensation test. The data from these tests were collected before taping, after taping and a 10-min rest, and immediately after continuous heel raises were performed to fatigue. The results of the balance tests showed no significant group × time interaction, whether subjects stood barefoot on one foot or stood on a soft mat with eyes open or closed (p > 0.05). Only the sway distance and sway velocity of the center of pressure (COP) when subjects stood barefoot on one foot with eyes open were significantly higher in the inhibition taping group than in the placebo taping group (p < 0.05). In addition, significant differences were noted in the sway area and sway distance of the COP before taping, after taping, and after exercise to fatigue when the participants stood on the soft mat with their eyes open (p < 0.05). When the participants stood on the soft mat on one foot with their eyes closed, no significant differences were noted among the groups. When subjects stood on a soft mat on one foot with eyes open, significant improvements were noted after fatiguing exercise versus before taping for all three groups (p < 0.05). The results of the superficial sensory test showed no significant group × time interaction and no difference among the three taping conditions or before/after taping and after fatiguing exercise. Only in the two-point discrimination test was a sensory difference observed, with the facilitation taping group having a significantly shorter discrimination distance than the placebo taping and inhibition taping groups (p < 0.05). The present study showed that KT application for a simple balance task (e.g., barefoot on a hard floor with eyes open) may slightly influence postural control, especially when the inhibition method is used. However, more difficult balance tasks (e.g., barefoot on a soft mat with eyes closed) show no effect of KT application-either the facilitation method or the inhibition method-on posture control.

Delayed peroneal muscle reaction time in male amateur footballers during a simulated prolonged football protocol

Peroneal muscle fatigue could result in ankle inversion sprain injuries. This study investigated the peroneal muscle reaction time during a simulated prolonged football protocol. Nine male footballers completed a 105-minute simulated prolonged football protocol. The peroneal muscle reaction time to an ankle inversion perturbation was measured every 15 minutes by a surface electromyography system sampling at 1000 Hz. One-way repeated ANOVA with post-hoc paired t-test showed a steady upward trend starting from 48.9 ms at baseline to 57.1 ms at the end of the first half, followed by a recovery back to 50.9 ms at the start of the second half and a further delay in the last 30 minutes to 60.2 ms at the end of the protocol. Delayed peroneal muscle reaction was found after 30 minutes of the first half and 15 minutes of the second half of a football match. The risk of ankle sprain could increase in the latter minutes in each half protocol. Thus, prevention injury training strategies should focus on these specific durations in football matches.

Kinesio taping does not improve ankle functional or performance in people with or without ankle injuries: Systematic review and meta-analysis

OBJECTIVE

To investigate whether Kinesio taping technique, applied to ankles of healthy people as a preventive intervention and people with ankle injuries, is superior to sham or alternative interventions on ankle function.

DATA SOURCES

Medline, Embase, Amed, CINAHL, SPORTDiscus, Cochrane Library and Web of Science, from inception to August 2020.

REVIEW METHODS

The terms "ankle" and "kinesio taping" were used in the search strategy. Included studies were randomized controlled trials (including crossover design) investigating Kinesio taping effects on ankle functional performance compared to any alternative or control/sham technique.

RESULTS

From 5,572 studies, 84 met the eligibility criteria which evaluated 2,684 people. Fifty-eight meta-analyses from 44 studies were performed (participants in meta-analyses ranging from 27 to 179). Fifty-one meta-analyses reported ineffectiveness of Kinesio taping: moderate evidence for star excursion balance test (anterior direction), jump distance, dorsiflexion range of motion, and plantar flexion torque for healthy people (effect size = 0.08-0.13); low to very-low evidence for balance, jump performance, range of motion, proprioception, muscle capacity and EMG for healthy people; balance for older people; and balance and jump performance for people with chronic instability. Seven meta-analyses reported results favoring Kinesio taping (effect size[95% CI]): low to very-low evidence for balance (stabilometry, ranging from 0.42[0.07-0.77] to 0.65[0.29-1.02]) and ankle inversion (0.84[0.28-1.40]) for healthy people; balance for older people (COP velocity, 0.90[0.01-1.78]); and balance for people with chronic instability (errors, 0.55[0.06-1.04]).

CONCLUSIONS

Current evidence does not support or encourage the use of Kinesio taping applied to the ankle for improvements in functional performance, regardless the population.

Injury prevalence and risk factors in a Greek team's professional football (soccer) players: a three consecutive seasons survey

This study investigated the prevalence and risk factors of injuries on a cohort of 123 Greek team's professional football players during three consecutive seasons, 2015/16-to-2017/18. Injuries were assessed and regression analysis was used to evaluate the potential risk factors. Three-quarters of the players were recorded as injured with 2.3 injuries/injured player, and the injury incidence was 55 injuries/1,000 match-playing-exposure-hours. The mean rehabilitation days were 29.3/injured player (95%CI 22.4-36.8) and 13.0/injury (95%CI 8.6-17.4). The majority of injured players has been found to have moderate-to-major/severe injuries and most of the injuries were traumatic than overuse (p < 0.05). The number of injuries were related to the recurrence of injury (beta = 0.646, p < 0.001) and the rehabilitations days (beta = 0.271, p < 0.001). High prevalence of injuries was found as the recurrence of injury and rehabilitation days were their main predictive risk factors. In order to reduce the risk of injuries, continuous effort is required in the rehabilitation of players.

Can compression stockings reduce the degree of soccer match-induced fatigue in females?

Soccer-induced fatigue and performance are different between the sexes. The effect of compression stockings (CS) use on fatigue during the soccer match in females is unknown. Thus, we evaluated the impact of CS use during a female soccer match on match-induced fatigue. Twenty soccer players were randomly allocated to two groups (n = 10 for each group): CS and Control (regular socks), and equally distributed within two teams. At rest (baseline 48-h before the match) and immediately post-match, we assessed agility T-test, standing heel-rise test and YoYo Intermittent Endurance Test level 2 (YoYoIE2) performance. Effort during the match (heart rate and rating of perceived exertion) was similar (p > 0.05) between groups. The YoYoIE2 performance was decreased post-match (p < 0.05) equally for both groups. Otherwise, the CS group exhibited a greater post-match performance (p < 0.05) for the agility T-test and heel-rise test (large effect sizes). Therefore, we conclude that the use of CS during an amateur female soccer match resulted in less match-induced fatigue.

The efficacy of elastic therapeutic tape variations on measures of ankle function and performance

OBJECTIVES

To investigate the effects of different variations of elastic therapeutic taping (ETT) on tests used to screen for ankle injury risk and function.

DESIGN

Randomized crossover.

SETTING

Laboratory.

PARTICIPANTS

Twelve professional male soccer players completed three experimental trials: No tape (NT), RockTape™ (RT), and Kinesio™ Tape (KT) applied to the ankle complex.

OUTCOME MEASURES

Clinical and functional ankle screening tests were used to assess the effects of ETT on measures of joint position sense, postural stability and ground reaction forces.

RESULTS

KT (P = 0.04) and RT (P = 0.01) demonstrated significant improvements in end range joint position sense. When compared to NT, RT significantly (P = 0.02) improved mid-range joint position sense at 15°, and time to complete a drop landing task. No significant differences were observed for measures of postural stability (P ≥ 0.12) nor ground reaction force variables (P ≥ 0.33).

CONCLUSIONS

Results advocate the use of ETT for proprioceptive and functional tasks when applied to the ankles of healthy male soccer players. However, a greater number of practical and significant differences were observed when RT only was applied, indicating that practitioners may potentially advocate the use of RT for tasks requiring proprioception and functional performance.
