Skin temperature in youth soccer players with functional equinus and non-equinus condition after running.

2018

Objectives To check how a thermal IR camera can check skin temperature in gastrocnemius‐soleus equinus condition and non‐gastrocnemius‐soleus condition in youth soccer players and thus detect association between the extensibility of the triceps surae (with gastrocnemius‐soleus equinus and non‐gastrocnemius‐soleus equinus) and the muscle temperature pattern. Design A cross‐sectional study secondary level of care. Methods Sample from an elite soccer academy in Madrid (Spain) 35 healthy male subjects (youth soccer players) age 12.82 ± 1.07 years, height 158.68 ± 10.79 cm, weight 49.19 ± 9.45 kg, body mass index 19.41 ± 2.25. The exclusion criteria were the presence of musculoskeletal and joint…

Achilles tendon length changes during walking in long-term diabetes patients

2010

Diabetes leads to numerous side effects, including an increased density of collagen fibrils and thickening of the Achilles tendon. This may increase tissue stiffness and could affect stretch distribution between muscle and tendinous tissues during walking. The primary aim of this study was to examine stretch distribution between muscle and tendinous tissues in the medial gastrocnemius muscle-tendon unit in long-term diabetes patients and control subjects during walking.Achilles tendon length changes were investigated in 13 non-neuropathic diabetes patients and 12 controls, whilst walking at a self selected speed across a 10 m force platform. Electromyographic activity was recorded in the me…

Effects of physical training on metabolism of connective tissues in young mice.

1980

The effects of physical training on the metabolism of collagen, calcium and glycosaminoglycans in various connective tissues were studied in male NMRI mice. The mice to be trained and their controls were about 3 weeks old (expt. I) and 8 weeks old (expt. II) at the commencement of training. The training was performed on a 5 degree inclined treadmill 5 days a week for 4 weeks in expt. I and for 3 weeks in expt. II. The daily exercise time was progressively increased from 20 min in the first week up to 80 min in the third week. The incorporation of 3H-proline to collagen hydroxyproline was increased by training in long bones, skeletal muscle and Achilles tendon, whereas the incorporation of 3…

Cumulative incidence of achilles tendon rupture and tendinopathy in male former elite athletes

2005

To study the cumulative incidence of Achilles tendon rupture and tendinopathy among former top-level athletes.Historical cohort study.Finland.Male former elite athlete cohort members (n = 785; median age, 69 years when responding to the questionnaire; range, 54-97) and their matched controls (n = 416; median age, 68 years; range, 56-94).Questionnaire-reported Achilles tendinopathy and tendon rupture diagnosed by physicians before the age of 45 years and within the subjects' lifetimes.Cumulative incidence of Achilles tendinopathy before the age of 45 was high for middle and long-distance runners (adjusted odds ratio, 31.2 compared with controls; P0.001), and cumulative incidence of Achilles …

Repeatability and sensitivity of passive mechanical stiffness measurements in the triceps surae muscle‐tendon complex

2021

Measurements of muscle-tendon unit passive mechanical properties are often used to illustrate acute and chronic responses to a training stimulus. The purpose of this study was to quantify the inter-session repeatability of triceps surae passive stiffness measurements in athletic and non-athletic populations, with the view to discussing its usefulness both as a muscle-tendon profiling tool and a control measure for studies with multiple data collection sessions. The study also aimed to observe the effects of quiet standing on passive stiffness parameters. Twenty-nine men (10 cyclists, nine triathletes, 10 controls) visited the laboratory on three separate occasions, where passive stiffness t…

Viscoelastic properties of the Achilles tendon in vivo

2013

It has been postulated that human tendons are viscoelastic and their mechanical properties time-dependent. Although Achilles tendon (AT) mechanics are widely reported, there is no consensus about AT viscoelastic properties such as loading rate dependency or hysteresis, in vivo. AT force-elongation characteristics were determined from 14 subjects in an ankle dynamometer at different loading rates using motion capture assisted ultrasonography. AT stiffness and elongation were determined between 10 – 80% of maximum voluntary contraction (MVC) force at fast and slow loading rates. As subjects were unable to consistently match the target unloading rate in the slow condition, AT hysteresis was on…

Biomechanical Diagnosis and Rehabilitation Control of Pes Equinus Patiens by Computerized Motion Analysis

1985

If a foot is fixed in plantar flexion such as to inhibit a dorsal flexion beyond a rectangular position with reference to the lower leg the resulting syndrome is called pes equinus. These patients exhibit a characteristic gait with stance phases on tiptoe that may amount to a severe handicap for them. The pes equinus is a most common deformity found in patients with a hemiplegic or diplegic disorder in the region of the foot and the lower leg with typical structural changes in the ankle joint and the calf muscles. The therapy of the pes equinus depends on its etiology and its severity. A less severe pes equinus deformity can be treated by physical therapy and other conservative measures. Mo…

Modulation of Cox-1, 5-, 12- and 15-Lox by Popular Herbal Remedies Used in Southern Italy Against Psoriasis and Other Skin Diseases

2014

Acanthus mollis (Acanthaceae), Achillea ligustica, Artemisia arborescens and Inula viscosa (Asteraceae) are used in Southern Italy against psoriasis and other skin diseases that occur with an imbalanced production of eicosanoids. We here assessed their in vitro effects upon 5-, 12-, 15-LOX and COX-1 enzymes as well as NFκB activation in intact cells as their possible therapeutic targets. All methanol crude extracts inhibited both 5-LOX and COX-1 activities under 200 µg/mL, without significant effects on the 12-LOX pathway or any relevant in vitro free radical scavenging activity. NFκB activation was prevented by all extracts but A. mollis. Interestingly, A. ligustica, A. arborescens and A. …
