Power output at the moderate-to-heavy-intensity transition decreases during prolonged exercise, and resilience to this has been termed 'durability'. The purpose of study was assess relationship between durability effect exercise on severe-intensity performance, explore intramuscular correlates durability.
Background: Techniques used in hip arthroscopy continue to evolve, and controversy surrounds the need for capsular repair following this surgical intervention. The purpose of study was evaluate magnetic resonance imaging (MRI) appearance capsule patients with femoroacetabular impingement (FAI) who underwent simultaneous bilateral through an interportal capsulotomy each randomized undergo or not such a repair. Methods: This double-blind, controlled trial included 15 (30 hips), mean age 29.2...
Abstract The Europa Thermal Emission Imaging System (E-THEMIS) on the Clipper spacecraft will investigate temperature and physical properties of using thermal infrared (TIR) images in three wavelength bands centered from 7-14 μm, 14-28 μm 28-80 μm. E-THEMIS map >80% surface at multiple times day a resolution 8-km per pixel, ∼32% percent ≤1 km/pixel resolution, ∼6% ≤100 m/pixel resolution. specific objectives investigation are to 1) understand formation features, including sites recent or...
Core stability has received considerable attention with regards to functional training in sports. provides the foundation from which power is generated cycling. No research described relationship between core and cycling mechanics of lower extremity. The purpose this study was determine stability. Hip, knee, ankle joint kinematic pedal force data were collected on 15 competitive cyclists while untethered a high-speed treadmill. exhaustive protocol consisted at 25.8 km x h(-1) grade increased...
Abstract Background: Under- and over-resection of cam-type femoroacetabular impingement are leading causes arthroscopic surgical failure. Although 3-dimensional imaging remains the gold standard, alpha angle measured from 2-dimensional is commonly used for resection planning evaluation but has poor validity detection medial or lateral under-resection. Both over- under-resection common iatrogenic This study presents intra- inter-rater reliability a novel pragmatic radiographic method...
The purpose of this study was to evaluate the magnetic resonance imaging (MRI) appearance hip capsule in patients with femoroacetabular impingement (FAI) undergoing arthroscopy capsular repair versus non-repair. A multicenter clinical trial performed 31 (49 hips) for treatment FAI. small- moderate-sized interportal capsulotomy performed. Each randomized non-repair capsulotomy. MRI at 6 and 24 weeks postoperatively analyzed by two musculoskeletal radiologists. Patients radiologists were...
Abstract Several proteins are implicated in transmembrane fatty acid transport. The purpose of this study was to quantify the variation oxidation rates during exercise explained by skeletal muscle involved Seventeen endurance-trained males underwent a (i) fasted, incremental cycling test estimate peak whole-body rate (PFO), (ii) resting vastus lateralis microbiopsy, and (iii) 2 h fed-state, moderate-intensity fed-state (FO). Bivariate correlations stepwise linear regression models PFO FO...
Background: Patients with pincer-type femoroacetabular impingement are commonly treated arthroscopic reduction of acetabular depth as measured by the lateral center-edge angle (LCEA). The optimal amount rim has not been established, although large resections may increase contact pressures through hip. A recent publication demonstrated inferior surgical outcomes in patients overcoverage compared normal coverage. Casual observation our database suggested equivalent improvements, prompting a...
Endurance athletes are frequently exposed to environmental heat stress during training. We investigated whether exposure 33°C training would improve endurance performance in temperate conditions and stimulate mitochondrial adaptations. Seventeen endurance-trained males were randomly assigned perform a 3-week intervention 18°C (TEMP) or (HEAT). An incremental test 30-min time-trial preceded by 2-h low-intensity cycling performed pre- post-intervention, along with resting vastus lateralis...
The New Zealand Rotator Cuff Registry represents the largest prospective cohort of rotator cuff repairs. Despite this, there are limited medium- to long-term data repair outcomes.To (1) analyze pain and functional outcomes a large primary repairs (2) evaluate effect patient factors tear characteristics on medium-term outcomes.Cohort study; Level evidence, 2.This was multicenter, multisurgeon study from March 2009 until December 2010. Surgical were collected by operating surgeon. Primary...
The New Zealand Rotator Cuff Registry was established in 2009 to collect prospective functional, pain and outcome data on patients undergoing rotator cuff repair (RCR).Information collected included an operation day technical questionnaire completed by the surgeon Flex Shoulder Function (SF) functional scores preoperatively, immediately post-operatively at 6, 12 24 months. A multivariate analysis performed analysing three surgical approaches determine if there a difference or scores.A total...
There is some evidence for temperature-dependent stimulation of mitochondrial biogenesis; however, the role elevated muscle temperature during exercise in adaptation to training has not been studied humans vivo. The purpose this study was determine elevating temperate conditions through application mild, local heat stress on adaptations endurance training. Eight endurance-trained males undertook 3 weeks supervised cycling training, which mild (~ 40 °C) applied locally upper-leg musculature...
Despite remaining a controversial diagnosis, piriformis syndrome continues to affect patients' quality of life with pain, sitting discomfort, and exercise intolerance. Open sciatic neurolysis has been noted by the senior author often only bring temporary relief symptoms, recurrence presumably due postoperative scar tissue. Minimally invasive techniques used decompress nerve have met mixed results. This article describes step-by-step surgical technique designed maximize patient safety, as...
Abstract This study aimed to determine whether the addition of platelet-rich plasma (PRP) during hip arthroscopy improves functional outcomes in femoroacetabular impingement (FAI) surgery. was a prospective randomized single-blinded trial arthroscopic patients aged between 16 and 50 years with diagnosis FAI conducted at single centre. Patients any previous surgery significant osteoarthritic changes (Tonnis grade > 2) were excluded. Before surgery, randomly assigned receive either PRP...
