Effects of TRX Suspension Training on Proprioception and Muscle Strength in Female Athletes with Functional Ankle Instability

Abstract

Background: Functional ankle instability (FAI) is a common consequence of ankle sprain injury, especially in high-impact sports. Objectives: To investigate the effect of six weeks of suspension training with total resistance exercises (TRX) on proprioception and muscle strength in female athletes with FAI. Methods: Thirty female athletes with FAI (age: 21.9 ± 2.2 years, height: 169.3 ± 4.2 cm, and weight: 59.8 ± 6.1 kg) were randomly assigned to two equally numbered groups: TRX training and controls based on inclusion and exclusion criteria. In the pre-test, the anthropometric variables and also proprioception accuracy and muscle strength of subjects were evaluated by joint angle reset test (JART) and manual muscle testing (MMT) in both dorsiflexion and plantarflexion motions. The training group completed three sessions per week with progressive load for six weeks, and each training session lasted 15 - 20 minutes, whilst control subjects continued with their normal activity without special sport activities. After six weeks of training, all tests performed in the pre-test phase were also performed in the post-test phase. The t-test was used for statistic analysis (α ≤ 0.05). Results: The findings showed that TRX training significantly improved the proprioception accuracy (P ≤ 0.001) and muscle strength (P ≤ 0.001) in the training group rather than the control group. No statistically significant difference was found in any of the tests between pre-test and post-test for the control group (P > 0.05). Conclusions: Six weeks of TRX suspension training had a positive effect on strength and proprioception accuracy in female athletes with FAI.

Aprendizaje cooperativo y entrenamiento en suspensión en Educación Secundaria: Incidencia en las necesidades psicológicas básicas (Cooperative learning and suspension training in Secondary Education: Incidence in the basic psychological needs)

“…El TRX, como método y equipamiento innovador que se está empezando a utilizar en las clases de EF, posibilita la ejecución de ejercicios utilizando la resistencia del propio cuerpo permitiendo trabajar en condiciones de inestabilidad, tanto de forma unilateral como bilateral, donde la dificultad puede ajustarse al modificar el ángulo del cuerpo en relación con el suelo (Demirarar et al, 2021). Los beneficios del uso del TRX se relacionan con: la mejora de la composición corporal, fuerza y resistencia muscular, y el equilibrio en atletas preadolescentes (Fayazmilani et al, 2022), mayor propiocepción y fuerza muscular en chicas atletas con inestabilidad de tobillo (Khorjahani et al, 2021), mejoras en el salto vertical en jóvenes jugadores de baloncesto (Demirarar et al, 2021) y mejoras en la flexibilidad en jóvenes judokas (Norambuena et al, 2021). Sin embargo, hay escasa evidencia científica sobre su uso en el ámbito educativo.…”

Investigating the Mediating Role of Pain in the Relationship between Ankle Joint Position Sense and Balance Assessed Using Computerized Posturography in Individuals with Unilateral Chronic Ankle Instability: A Cross-Sectional Study

“…A significant contribution is made by the proprioceptive information acquired from the receptors in the joints and muscles [6]. Proprioceptive information from the ankle muscles is important [7]. The ankle proprioception is impaired in individuals with ankle sprains, contributing to the development and maintenance of chronic ankle instability (CAI) [8].…”

The effect of TRX, combined with vibration training, on BMI, the body fat percentage, myostatin and follistatin, the strength endurance and layup shot skills of female basketball players

“…This, in turn, leads to alterations in muscle contraction through reflex muscle activity and the activation of muscle spindles [ 6 ]. Studies have shown that higher vibration frequencies (35–45 Hz) used in conjunction with attachment cords for static and dynamic exercises significantly increase muscle activation compared to lower frequencies (35 Hz) [ 7 , 8 ]. TVT is a sophisticated form of resistance training that does not rely on traditional weights.…”
