The purpose of this study was to concurrently determine the effect that plyometric and isometric training has on tendon stiffness (K) muscle output characteristics compare any subsequent changes.Thirteen men trained lower limbs either plyometrically or isometrically 2-3 times a week for 6-week period.Medial gastrocnemius measured in vivo using ultrasonography during ramped contractions before after training.Mechanical variables were force plate concentric efforts.Signi�icant (p < 0.05)...
Congenital abnormalities of the kidney and urinary tract are most common cause pediatric failure. These disorders highly heterogeneous, etiologic factors poorly understood.We performed genomewide linkage analysis whole-exome sequencing in a family with an autosomal dominant form congenital or (seven affected members). We also sequence 311 unrelated patients, as well histologic functional studies.Linkage identified five regions genome that were shared among all members. Exome single, rare,...
Abstract Human patellar tendon stress (σ), strain (ε), stiffness ( K ), and tensile or Young's modulus E are determined in vivo through voluntary isometric contractions monitored with B‐mode ultrasonography. The limitations previous studies are: (1) they have generally not accounted for the fact that distal attachment of (the tibial tuberosity) also displaces; thus, underestimated ε (and, hence, injury risk) while overestimating ; (2) no gender effect has been studied despite females seen to...
Stretching is commonly used prior to exercise, as it thought reduce the risk of injury, and also in preconditioning tendon grafts. As properties have been shown be different between genders, proposed that stretching will differentially affect structure. Here we examine effect acute stretch on mechanical both male female medial gastrocnemius tendon. Female [20 years +/- 1 (SEM), n = 17] (22 1, 18) subjects underwent a 5-min passive dorsiflexion stretch. Prior post stiffness (K), length (l)...
Burgess, KE, Pearson, SJ, and Onambélé, GL. Patellar tendon properties with fluctuating menstrual cycle hormones. J Strength Cond Res 24(8): 2088-2095, 2010-Debate continues over whether skeletal muscle performance injury risk vary the course of cycle. Alterations in may play a role potential fluctuations both these variables. The aim current study was to determine any association between phase corresponding levels female sex hormones properties. Fifteen normally menstruating (28-32-day...
Elderly women are reportedly at higher risk of falling than their male counterparts. Postural balance is highly associated with fall and also correlated tendon structural mechanical properties. Gender differences in properties could partly explain the discrepancy risk. Thus purpose this study was to investigate possible gender difference elderly. The patellar 55 elderly (men n = 27, aged 72 +/- 1 years, 28, 70 years) participants were tested. Tendon stiffness (K), length (L), cross-sectional...
Relaxin (hRLX) is a hormone reported to affect collagen synthesis. Its effects are also thought be modulated by other sex hormones, including oestrogen, which has previously been found associated with alterations of in vivo tendon properties. There thus potential for hRLX impact on collagen, could result structural and mechanical properties being modified. The present study therefore aimed determine any interaction between stiffness, normally menstruating women (n = 12). Tendon were...
Objectives: To investigate the validity and relative absolute reliability of Running Anaerobic Sprint Test (RAST) in ama teur soccer players. Design: Cross-sectional experimental design with an element repeated measures. Methods: Twenty three males completed RAST on two occasions a Wingate test (WAnT) as criterion measure anaero bic power. Results: Criterion for was strong peak power (r = 0.70, p < 0.001) average 0.60, 0.002); however, significantly underestimated compared to WAnT. The...

Thirteen men trained lower limbs either plyometrically or isometrically 2–3 times a week for 6-week period.

This study investigated the effects of measurement error and testing frequency on prediction accuracy standard fitness-fatigue model. A simulation-based approach was used to systematically assess inputs commonly when monitoring training athletes. Two hypothetical athletes (intermediate advanced) were developed realistic loads daily ‘true’ power values generated using model across 16 weeks. Simulations then completed by adding Gaussian errors true with mean 0 set deviations recreate more less...
'Climb assist' claims to reduce strain when climbing ladders; however, no research has yet substantiated this. The purpose of this study was assess the physiological and psychophysical effects climb assist on 30 m ladder at a minimum acceptable speed. Eight participants (six male two female) climbed 24 rungs per minute with without assist, were monitored for heart rate (HR), O2 perceived exertion (RPE). All three variables decreased significantly (p < 0.05) decreasing by 22.5%, HR 14.8% RPE...
This study aimed to assess the effect of extreme environmental exposure during an operational saturation dive on airway inflammation (exhaled nitric oxide (FeNo)), components fitness (flexibility and aerobic capacity) blood hematological variables. Six divers, who undertook a 26±0.5 day were recruited take part in this study. Participants completed field-based repeated measure test battery three occasions (pre-dive, post-dive 24 hours after dive). Hemoglobin concentration was significantly...
