The purpose of this study was to examine patellar tendon (PT) size and mechanical properties in subjects with a side-to-side strength difference > or =15% due sport-induced loading. Seven elite fencers badminton players were included. Cross-sectional area (CSA) the PT obtained from MRI ultrasonography-based measurement tibial movement together force during isometric contractions used estimate bilaterally. We found that distal PT, but not mid-tendon, CSA greater on lead extremity compared...
Age-related loss in muscle mass and strength impairs daily life function the elderly. However, it remains unknown whether tendon properties also deteriorate with age. Cross-linking of collagen molecules provides structural integrity to fibrils has been shown change age animals but never examined humans vivo. In this study, we mechanical pyridinoline pentosidine cross-link concentrations patellar vivo old (OM) young men (YM). Seven OM (67 ± 3 years, 86 10 kg) YM (27 2 81 8 a similar physical...
Background: Treatment strategies for Achilles tendon rupture vary considerably, and clinical outcome may depend on the magnitude of elongation after surgical repair. The aim this project was to examine whether elongation, mechanical properties, functional outcomes during rehabilitation surgically repaired acute ruptures were influenced by different regimens early postsurgical period. Hypothesis: Restricted weightbearing that permits only limited motion about ankle in phase healing limits...
Background Eccentric hip adduction and abduction strength plays an important role in the treatment prevention of groin injuries soccer players. Lower extremity deficits less than 10% on injured side, compared to uninjured have been suggested as clinical milestone before returning sports following injury. Objective To examine whether a side-to-side eccentric or symmetry can be assumed non-injured players matched controls. Material Methods Nine elite 19.4 (1.5) years nine recreational athletes...
Diabetic patients have an increased risk of foot ulcers, and glycation collagen may increase tissue stiffness. We hypothesized that the level glycemic control (glycation) affect Achilles tendon stiffness, which can influence gait pattern. therefore investigated relationship between glycation, stiffness parameters, plantar pressure in poorly (n = 22) well controlled diabetic patients, including healthy age-matched (45-70 yr) controls 11). There were no differences any outcome parameters...
Abstract Overloading of tendon tissue with resulting chronic pain (tendinopathy) is a common disorder in occupational‐, leisure‐ and sports‐activity, but its pathogenesis remains poorly understood. To investigate the very early phase tendinopathy, Achilles patellar tendons were investigated 200 physically active patients 50 healthy control persons. Patients divided into three groups: symptoms for 0‐1 months (T1), 1‐2 (T2) or 2‐3 (T3). Tendinopathic cross‐sectional area determined by...
Background: Loading interventions have become a predominant treatment strategy for tendinopathy, and positive clinical outcomes tendon tissue responses may depend on the exercise dose load magnitude. Purpose/Hypothesis: The purpose was to investigate if magnitude influenced effect of 12-week loading intervention patellar tendinopathy in short term (12 weeks) long (52 weeks). We hypothesized that greater 90% 1 repetition maximum (RM) would yield more outcome, structure, function compared with...
Abstract Background To investigate how anatomical cross-sectional area and volume of quadriceps triceps surae muscles were affected by ageing, resistance training in older younger men, vivo. Methods The old participants randomly assigned to moderate (O55, n = 13) or high-load (O80, 14) intervention (12 weeks; 3 times/week) corresponding 55% 80% one repetition maximum, respectively. Young men (Y55, 11) the moderate-intensity strengthening exercise program. Each group received exact same on...
To investigate whether low-level laser therapy (LLLT) can reduce pain from tendinopathy, we performed a review of randomized placebo-controlled trials with LLLT for tendinopathy. The literature search using published after 1980 was conducted on Medline, Embase, and the Cochrane Library, together hand-search physiotherapy journals in English Scandinavian languages. Validity assessment each trial done according to predefined criteria location-specific dosage irradiation skin directly overlying...
Objective: Myofascial pain syndromes associated with trigger points [TrPs] are an established clinical entity but the structural and functional abnormalities of TrPs not well under stood. The aim study was to conduct a blinded electromyographic investigation TrPs.Methods: Nineteen young subjects chronic shoulder arm pain, who had TrP [i.e., tender point referred producing at least some complaint] in infraspinatus muscle, were examined. This nontender control same muscle code-marked, order...
Myofascial pain syndromes due to trigger points (TrPs) are clinical entities, but more evidence is needed evaluate TrP palpation. Chronic tension-type headache (CTTH) the most prevalent chronic with high socioeconomic costs. The primary aim was study whether palpation can distinguish patients from healthy controls.Double-blinded, controlled design.Twenty diagnosis of CTTH, and 20 age-matched sex-matched control participants.TrP revealed TrPs in (N=17) versus controls (N=6) (P=0.0005)....
The aim of this study was to examine the structural and mechanical properties patellar tendon in elite male badminton players with without tendinopathy. Seven unilateral tendinopathy ( PT group) on lead extremity (used for forward lunge) nine no current or previous CT were included. Magnetic resonance imaging used assess distal dimensions. Patellar assessed using simultaneous force deformation measurements. Distal cross‐sectional area CSA ) normalized body weight (mm 2 /kg 2/3 lower group...
To investigate the influence of lifelong endurance running on satellite cell pool type I and II fibres in healthy human skeletal muscle.Muscle biopsies were collected from 15 old trained men (O-Tr) who had been 43 ± 16 (mean SD) kilometres a week for 28 9 years. Twelve age-matched untrained (O-Un) group young recruited comparison. Frozen sections immunohistochemically stained Pax7, myosin laminin, which fibre area, number cells, relationship between these variables determined.In O-Un O-Tr,...
Introduction: The majority of young women use oral contraceptives (OCs). Use OCs has been associated with lower myofibrillar protein and tendon collagen synthesis rates, but it is unknown whether will limit the adaptive response myotendinous tissue to resistance training. Design Methods: Fourteen healthy untrained regular OC users (24 ± 1 years, fat% 32 1, 35 2 ml⋅min-1⋅kg-1) 14 NOC (non-OC, controls) 2, 34 performed a 10-week supervised extremity progressive training program. Before after...
Heavy controlled loads of tendon with prolonged time under tension remain the treatment choice in tendinopathy rehabilitation. The use low-load resistance exercise (LL, 20%-40% 1-RM) combination blood flow restriction (BFR) has been advocated as a clinically important rehabilitation tool for persons not tolerating high muscle-tendon loads. Similar or improved clinical outcomes have reported after LL-BFR compared to conventional following various types knee injury, and also load-matched,...
The objective of this study was to investigate subchondral bone turnover at rest and after acute loading using Fluorine-18-labeled sodium fluoride (Na[18F]F) Positron Emission Tomography (PET), in patients with unilateral PFP. Twenty-seven PFP were recruited from the Institute Sports Medicine Copenhagen. Participants underwent Na[18F]F-PET imaging before a bout single-leg squats. Bone measures, including mean maximal standardized uptake value (SUVmean SUVmax), rate perfusion (K1), tracer...
