STUDY DESIGN Single-group repeated measures design. OBJECTIVE To quantify patellofemoral joint reaction forces and stress while squatting with and without an external load. BACKGROUND Although squatting exercises in the rehabilitation setting are often executed to a relatively shallow depth in order to avoid the higher joint forces associated with increased knee flexion, objective criteria ...

Typo-squatting refers to the practice of registering domain names that are typo variations of popular websites. We propose a new approach, called Strider Typo-Patrol, to discover large-scale, systematic typosquatters. We show that a large number of typosquatting domains are active and a large percentage of them are parked with a handful of major domain parking services, which serve syndicated a...

BACKGROUND To evaluate changes in pulse pressure (PP) and markers of cardiovascular autonomic neuropathy (CAN) according to duration of type 1 diabetes mellitus (T1DM). METHODS This cross-sectional controlled study evaluated 159 diabetic patients during a 3-min posture test (standing-squatting-standing) with continuous measurement of systolic (SBP), diastolic (DBP) and mean (MBP) blood pressu...

We conducted a field experiment to test the benefit from late bidding (sniping) in online auction markets. We compared sniping to early bidding (squatting) in auctions for newly-released DVDs on eBay. Sniping led to a statistically significant increase in our average surplus; however, this improvement was quite small. Nevertheless, the two bidding strategies resulted in a variety of other quali...

Aims We assessed changes in pulse pressure (PP) and heart rate (HR) during a squatting test, as indirect markers of arterial stiffness and cardiovascular autonomic neuropathy (CAN), respectively, according to age and gender in patients with type 1 diabetes mellitus. Methods We evaluated 160 diabetic patients, divided in four groups of 20 men/20 women according to age (G1: 20–30 years; G2: 31–40...

Previous gait studies on squatting have described a rapid reversal in the direction of the tibiofemoral joint shear reaction force when going into a full weight-bearing deep knee flexion squat. The effects of such a shear reversal have not been considered with regard to the loading demand on knee implants in patients whose activities of daily living require frequent squatting. In this paper, th...

Repeated biopsy sampling from one muscle is necessary to investigate muscular adaptation to different forms of exercise as adaptation is thought to be the result of cumulative effects of transient changes in gene expression in response to single exercise bouts. In a crossover study, we obtained four fine needle biopsies from one vastus lateralis muscle of 11 male subjects (25.9 ± 3.8 yr, 179.2 ...
