Soft Tissue Deformations Contribute to the Mechanics of Walking in Obese Adults
BIOMECHANICS JOINT LOADS ENERGY EXPENDITURE GAIT LOCOMOTION
2017/4/19
Obesity not only adds to the mass that must be carried during walking but also changes body composition. Although extra mass causes roughly proportional increases in musculoskeletal loading, less well...
VO2max and Microgravity Exposure: Convective versus Diffusive O2 Transport
MICROGRAVITY SPACEFLIGHT VO2max EXERCISE
2017/4/19
Exposure to a microgravity environment decreases the maximal rate of O2 uptake (V˙O2max) in healthy individuals returning to a gravitational environment. The magnitude of this decrease in V˙O2max is, ...
Effect of Intravenous Iron on Aerobic Capacity and Iron Metabolism in Elite Athletes
ENDURANCE V˙O2MAX HEMOGLOBIN HEPCIDIN FERRITIN INTERLEUKIN-6
2017/4/19
Purpose: Iron-deficient athletes are often treated with long-term, low-dose iron therapy. Such treatments may be efficacious in correcting iron deficiency; however, the effect on acute and chronic iro...
Strength Asymmetry and Landing Mechanics at Return to Sport after Anterior Cruciate Ligament Reconstruction
ANTERIOR CRUCIATE LIGAMENT RECONSTRUCTION QUADRICEPS WEAKNESS LANDING KINEMATICS KINETICS
2017/4/19
Purpose: Evidence-based quadriceps femoris muscle (QF) strength guidelines for return to sport after anterior cruciate ligament (ACL) reconstruction are lacking. This study investigated the effect of ...
Lower Limb Landing Biomechanics in Subjects with Chronic Ankle Instability
ANKLE INSTABILITY KINEMATICS FORWARD JUMP SIDE JUMP IMPACT PHASE
2017/4/19
Purpose: The literature on lower limb kinematic deviations in subjects with chronic ankle instability (CAI) during landing tasks is limited and not consistent. Several studies only report joint angles...

3D KINEMATICS FORCE COMPONENTS KINETICS PRESSURE DISTRIBUTION INSOLES PROPULSIVE FORCE
2017/4/19
Purpose: To describe the detailed kinetics and kinematics associated with use of the V1 skating technique at high skiing speeds and to identify factors that predict performance.
Methods: Fifteen elit...
Analysis of a Severe Head Injury in World Cup Alpine Skiing
TRAUMATIC BRAIN INJURY SKIING INJURY ALPINE SKIING HELMET BIOMECHANICS MODEL-BASED IMAGE MATCHING TECHNIQUE
2017/4/19
Traumatic brain injury (TBI) is the leading cause of death in alpine skiing. It has been found that helmet use can reduce the incidence of head injuries between 15% and 60%. However, knowledge on opti...
No Association between Vitamin D Deficiency and Markers of Bone Health in Athletes
VITAMIN D INSUFFICIENCIES BONE MINERAL DENSITY T-SCORE ATHLETE HEALTH
2017/4/19
Purpose: Adequate vitamin D (25(OH)D) is required to maintain good bone health, yet many athletes are 25(OH)D deficient. This study sought to examine the relation between serum 25(OH)D and measures of...
Tendinopathy Alters Cumulative Transverse Strain in the Patellar Tendon after Exercise
TENDON REHABILITATION ULTRASOUND BIOMECHANICS FLUID FLOW COLLAGEN
2017/4/14
Introduction: This research evaluated the effect of tendinopathy on the cumulative transverse strain response of the patellar tendon to a bout of resistive quadriceps exercise.
Methods: Nine adults w...
