Abstract Wild bearded capuchins ( Cebus libidinosus , quadrupedal, medium‐sized monkeys) crack nuts using large stones. We examined the kinematics and energetics of nut‐cracking action two adult males females. From a bipedal stance, monkeys raised heavy hammer stone (1.46 1.32 kg, from 33 to 77% their body weight) an average height 0.33 m, 60% length. Then, they rapidly lowered by flexing lower extremities trunk until contacted nut. A hit consisting upward phase downward averaged 0.74 s in...

Abstract Objective Develop and evaluate an automated case detection response triggering system to monitor patients every 5 min identify early signs of physiologic deterioration. Materials methods A 2-year prospective, observational study at a large level 1 trauma center. All admitted 33-bed medical oncology floor (A) non-intensive care unit (ICU) surgical (B) were monitored. During the intervention year, pager alerts deterioration automatically sent charge nurses along with access graphical...

The purpose of the current study was to identify biomechanical features elite female baseball pitching. Kinematics and kinetics eleven pitchers were reported compared with male pitchers. Results suggested that females share many similarities males in pitching kinematics, a few significant differences. Specifically, at instant stride foot contact, pitcher had shorter more open less separation between pelvis orientation upper torso orientation. From contact ball release, produced lower peak...

Little is known about shear loading patterns during dance movements. The purpose of the study was to investigate effect jumping distance (JD) on contributors ankle and knee forces (SF) generated landing phase traveling jumps. Six female dancers performed 10 trials each at 30, 60, 90% maximum jump 15 jumps ranging from 35 100% JD. A sagittal view right leg onto a force platform filmed using high-speed cine camera. Greater joint reaction (JRSF) quadriceps SF (QuadSF) were observed (P < 0.05)...

Background: Patellar tendinopathy (PT) is a common degenerative condition in physically active populations. Knowledge regarding the biomechanics of landing populations with symptomatic PT limited, but altered mechanics may play role development or perpetuation PT. Purpose: To identify whether study participants exhibited different kinematics compared healthy controls. Study Design: Controlled laboratory study. Methods: Sixty recreationally took part this study; 30 had current signs and...

Several case studies observed that the lateral ankle sprain resulted from a sudden increase in inversion accompanied by internal rotation. However, without sufficient kinetics and muscle activity information literature, detailed mechanism of is still unrevealed. The purpose our report to present 2 accidental giving way incidents for participants with chronic instability (CAI) compare their normal trials data kinematics, kinetics, electromyography (EMG).Two young female accidentally...

Breathing rates during physical exercise suggest that, these conditions, the high-frequency (HF) bandwidth of heart rate variability (HRV) analysis should be extended beyond conventional guidelines. However, there has been little investigation most appropriate choice HF exercise. HRV was performed in 10 males and six females progressive bicycle Cardiac cycle (RR) interval breath-by-breath respiratory data were simultaneously recorded. powers determined for band-limited ranges 0.04-0.15 Hz...

Knowledge of the magnitude and rate applying axial forces (AF) during actual dance movements is necessary for understanding etiology chronic injuries osteoarthritis. The purpose this study was to investigate effect jumping distance on component ankle knee joint AFs generated landing phase traveling jumps. Six female dancers performed 10 jumps each at 30, 60, 90% maximum jump (JD) 15 ranging from 35 100% JD. A sagittal view right leg onto a force platform filmed. Greater ground reaction...

This study aimed to test the utility of ozone challenge model for profiling novel compounds designed reduce airway inflammation. The authors used a randomized, double‐dummy, double‐blind, placebo‐controlled 3‐period crossover design alternating single orally inhaled doses fluticasone propionate (inhaled corticosteroids, 2 mg), oral prednisolone (oral 50 or matched placebo. Ata 2‐week interval, 18 healthy responders (&gt;10% increase in sputum neutrophils) underwent 3‐hour (250...

The investigation of the effects speed related changes on joint moments may be an optimal method to study injury mechanisms indirectly and identify accommodation strategies varied impact loading forces incurred during running. Four skilled long-distance runners performed eight trials at each four target speeds (3.06, 3.57, 4.09, 4.60 m/s). Peak about ankle, knee, hip relative absolute times for various temporal events were evaluated. moment parameters exhibited greatest number (59.0%)...

One potential ACL injury situation is due to contact with another person or object during the flight phase, thereby causing land improperly. Conversely, athletes often have flight-phase collisions but do safely. Therefore, better understand causation and methods by which people typically safely, purpose of this study was determine effects an in-flight perturbation on lower extremity biomechanics displayed females typical drop landings. Seventeen collegiate female recreational performed...

Abstract This study assessed the accuracy of marker-based kinematic analysis fingers, considering soft tissue artefacts (STA) and marker imaging uncertainty. We collected CT images hand from healthy volunteers with fingers in full extension, mid- full-flexion, including motion capture markers. Bones markers were segmented meshed. The bone meshes for each volunteer’s scans aligned using proximal phalanx to interphalangeal joint (PIP), middle distal (DIP). angle changes between positions...

Abstract Two unique methodological strategies were used to investigate the influence of retroactive inhibition on recall within a contextual interference paradigm. Three independent blocked groups, without (BL-without), with 18 trials (BL-18), and 36 (BL-36), created that varied in order presentation tasks. By testing single task retention creating three varying amounts produced. This isolated effects compared control random subjects' retention. The Acquisition Group x Retention Trials...
