Abstract:
We explore here the evolution of skiing locomotion in the last few thousand years by investigating how humans adapted to move effectively in lands where a cover of snow, for several months every year, prevented them from travelling as on dry ground. Following historical research, we identified the sets of skis corresponding to the ‘milestones’ of skiing evolution in terms of ingenuity and technology, built replicas of them and measured the metabolic energy associated to their use in a climate-controlled ski tunnel. Six sets of skis were tested, covering a span from 542 AD to date. Our results

In the late 19th century skiers appeared in Lviv, where in the early 20th century the sport began to be promoted by the Popular Entertainment Society.

To understand cross-country (X-C) siding it is important to record and identity forces of skis and poles separately and together. They both contribute to the forward progression, but their functional significance may be more complex than that of the ground reaction forces in running and walking. This report presents two methods to record forces on skis and poles during normal X-C skiing. A long force-platform system with four rows of 6-m long plates is placed under the snow track for recording of Fz and Fy forces of each ski and pole separately.

Alpine skiing is a complex sport that demands a high level of motor control and balance. In general, skiers are prone to deterioration in the state of fatigue due to using inappropriate equipment. As a consequence, the risk of injury might increase. This study aimed to examine the influence of fatigue and ski waist-width on knee-joint stability and skier’s balance.

Abstract:
In the past few years there has been a change from emphasizing the classical cross-country ski technique to introducing the skating technique. Use of the skating stride has led to the adoption of roller skates instead of the ratchet-type roller skis for dryland training. Therefore the question arises as to whether the roller skates simulate the movement pattern observed on snow. This study attempted to answer this question and to evaluate the movement similarity between a newly designed skating-specific roller ski and snow skis in performing the skating stride.

Ideal carving occurs when a snowboarder or skier, equipped with a snowboard or carving skis, describes a perfectly carved turn in which the edges of the ski alone, not the ski surface, describe the trajectory followed by the skier, without any slipping or skidding.

The parameters of the ideal-carving equation are the inclination of the ski slope, the acceleration of gravity, and the sidecut radius of the ski. The vari

Abstract:
This study examined whether gate setup and turn radii influence energy dissipation in slalom skiing. 3D kinematical measurements were performed over two runs on the same slope in a WC slalom competition with two different gate setups: 1) open gates (OG) and 2) open gates with a delayed gate (DG). Using the arithmetic mean of the skis’ turn radii (RAMS) the slalom turns were divided into 1) initiation phase (RAMS> 15m) and steering phase (RAMS< 15m). The results show differences between OG and DG regarding: 1) the absolute center of gravity’s (CG) velocity, 2) absolute acceleration, 3) CG

Patients with a history of or a predisposition to autoimmune or collagen vascular diseases are inclined to develop drug-induced subacute cutaneous lupus erythematosus (SCLE) due to terbinafine therapy. Here, we report a case of terbinafine-induced SCLE in a male patient, although classic SCLE most commonly affects females, and he did not have a diagnosis of or a history suggestive of a predisposition to autoimmune or collagen vascular diseases. Although the mechanism for terbinafine-induced SCLE has not been fully elucidated, we suggest that there may be distinctive mechanisms of terbinafine-i

Mycobacterium marinum is typically seen in patients who have a history of exposure to aquariums. We report a unique case of M. marinum that developed on the right knee following participation in a Hurricane Katrina reconstruction project. We are hopeful that this report will alert providers to elicit a thorough history and include cultures for less commonly encountered infectious agents along with routine bacterial and fungal stains and cultures when seeing patients with particular exposure histories such as this.

Sandwich beam dynamic response and the degree of structural degeneration under impact loading both depends on the thickness of metallic skins. The projectile impact test demonstrate difference damage characteristics between the sandwich beams with different thickness skins.

Moreover, it analyses time derivatives of total W EX, of W EX performed by the roller-skis and poles, respectively, and of the directly useful mechanical work (the sum of the work to overcome centre of mass’ gravity and rolling resistance) within a typical roller-skiing cycle.

Abstract:
A 1:1 locomotion–respiration entrainment is observed in galloping quadrupeds, and is thought to improve running economy. However, this has not been tested directly in animals, as animals cannot voluntarily disrupt this entrainment. The purpose of this study was to evaluate metabolic economy in a human gait involving all four limbs, cross-country skiing, in natural entrainment and forced nonentrainment. Nine elite cross-country skiers roller skied at constant speed using the 2-skate technique. In the first and last conditions, athletes used the natural entrained breathing pattern: inhaling with

Capecitabine is a fluoropyrimidine chemotherapy prodrug of 5-fluorouracil (5-FU) used in the treatment of metastatic breast and colorectal cancers. Drug-induced subacute cutaneous lupus erythematosus (DI-SCLE) is a rare side effect of capecitabine therapy, with eight cases previously reported. We report a case of DI-SCLE in a patient with a documented history of systemic lupus erythematosus (SLE). This is the second documented case of DI-SCLE in a patient with a past medical history of SLE, and provides evidence that there may be an increased risk of DI-SCLE in these patients. Further research

A new method was developed for measuring the distribution of real time ground reaction forces under the snow ski. A platform composed of 20 separate beams was buried in snow under the ski track. Vertical, cross horizontal, and longitudinal horizontal force components were measured with strain gauge bridges separately on each beam, and the results were recorded with a data logger at 90 Hz. The test results for two types of skating skis are described. Anomalous behavior was observed in horizontal force components, where negative force values were recorded on some sections of the ski at the end o

Background: Although considered a tropical disease, strongyloidiasis may be encountered in non-endemic regions, primarily amongst immigrants and travelers from endemic areas. Chronic strongyloides infection may be under-detected owing to its non-specific cutaneous presentation and the low sensitivity of commonly used screening tools. Methods: 18 consecutive patients with serologic evidence of strongyloides infestation who presented to a single urban, academic dermatology clinic between September 2013 and October 2016 were retrospectively included.
