“…Crystal Naomi et al 21 avaliaram o pico de torque extensor do joelho após resfriamento e não foi verificada uma alteração significativa deste após resfriamento 21 . Mustalampi et al 22 examinaram os efeitos agudos da crioterapia em 39 sujeitos saudáveis sobre a propriedade muscular do quadríceps. Estes autores observaram que o quadríceps tornou-se tenso, rígido e pouco elástico, após a aplicação, e que suas propriedades demoraram mais de 15 minutos para se normalizarem 22 .…”

“…Muscle elasticity is characterised by logarithmic decrement of oscillations, i.e., the coefficient of elasticity. It has been noticed that the greater the logarithmic decrement of damped oscillations, the lower the muscle elasticity [16][17][18].…”

Asymmetry of body parts refers to absence of symmetry and unevenly developed body parts in terms of the axis and plane. It has been long ago noticed that no perfectly correct human body exists, and bodies are to a greater or lesser extent asymmetric. A passive way of life, insufficient movement and inappropriate ergonomics of the workplace have a negative impact on the skeletal muscle system, usually resulting in reduced muscle power, static and dynamic muscle endurance, and altered muscle tone. The aim is to determine whether muscle myotonometry parameters are informative in early risk diagnostics to predict the likelihood of skeletal muscle system trauma. The study involved 382 people aged 18-24. Participants were devided into two groups: according to the accumulated composite score. Testing was made one time. The study consisted of functional movement and myotonometry evaluation. The study analyses and presents comparisons of the results depending on the trauma likelihood and sex. In addition, asymmetry of the left and the right body side is investigated. The analysis of the asymmetries (delta) in the frequency of damped oscillations of trapezius, biceps femoris, gastrocnemius (inner and outer part) on the left and right sides of the body demonstrated greater asymmetries between the left and the right sides of the body in the groups of both men and women with a lower chance of trauma. The assessment of asymmetries in femoris rectus and tibialis anterior between the left and the right sides of the body showed differences in the frequency of damped oscillations in all groups. Muscle myotonometry parameters are informative and may be used in early risk diagnostics to predict skeletal muscle system trauma. The asymmetry in tibialis muscle tone between the left and the right leg causes poorer parameters of functional movement performance in women. No associations were found to exist with the ability to perform functional movements in men. The asymmetry in femoris muscle tone between the left and right leg demonstrates the ability of young subjects to perform functional movements. It is characteristic of men and, to a lower extent, of women.

“…Chesterton also mentioned reducing tissue temperature to <12. 5 C to reduce nerve conduction velocity and to [10][11] C to reduce enzyme activity. 2 It is thought that decreasing intramuscular temperatures by [7][8] C reduces blood flow and metabolic requirements.…”

“…6 Similarly, in other studies, the skin temperatures produced by a 20-minute gel pack applied to the thigh over one layer of towel also suggested that the towel reduced effectiveness. 7,10 To what extent can absence of cryotherapy effects following soft-tissue injury be explained by the use of short-duration treatments, failure to compress the cooling agent against the skin, and inclusion of insulating material in the application?…”
