A Hike through History: Students Explore the Appalachian Trail

Hiking is a great way to get outside, commune with nature, and connect with the surrounding area. A few weeks ago, I had the pleasure of hiking one of my favorite sections of the Appalachian Trail in a manner that was completely different than I had ever before experienced. Instead of dressing in my usual 21st century hiking attire, I, along with several others, opted to take things back about 154 years and dressed as a Union soldier would have in 1862. [excerpt

Hiking Gears Comparing System (HGCS) using web scraping technique / Azrul Nazrin Hamdan

This project is about the development of Hiking Gears Comparing System (HGCS) for people who love to do hiking activity around Malaysia. Hiking is one of the favorite outdoor activities in Malaysia. One of the factors of people tend to carry out hiking activity is because the Malaysia landform that has many hills and mountain. So, people in Malaysia like this challenging activity to fulfill their interest and care about their healthiness. In order to carry out this activity, hikers need to use the suitable equipment or gears. Hiking gears consist of hiking backpacks, hiking footwear, hiking clothing, tents and survival kit. Hikers normally buys the hiking gears either walk in at the shop or buy through online. The problems that have been identified when the hikers want to buy the hiking gears, most of them do not know the best websites that promote the best products based on the price and the functionality. They need to open many websites to make a survey for the products that they want to buy. HGCS used the web scraping technique to extract the data from the websites that provide hiking gears. This technique has been identified in the knowledge acquisition phase. From the extracted data, HGCS will compare the products based on price, product category and functionality. This project applied the waterfall model methodology. The phases included in this project is knowledge acquisition, requirement gathering and analysis, design and implementation. Findings and analysis was done to ensure that the objectives of this project are tally with the phases in methodology. For the future work, this system may include some others outdoor activities gears, for example, rock climbing gears, cycling gears or kayaking gears. In addition, extract data from more websites that sell the hiking gears by using the web scraping technique

QUALITY OF DINGHY HIKING: EFFECTS ON SPEED AND HEADING

Dinghy hiking uses the sailor’s bodyweight to produce a ‘righting moment’ which counteracts the moment of force caused by the wind on the sail. However, hiking is a physically demanding activity and maintaining quality hiking technique throughout a race is essential in competitive sailing. A land-based hiking simulator has been used to assess hiking technique, but no data were available to relate simulator results to on-water performance. This project evaluated the effect of decreased quality hiking positions on actual on-water dinghy speed and heading

THE EFFECTS OF SHOE TYPE ON BIOMECHANICAL AND PHYSIOLOGICAL RESPONSES TO STEPPING AND INCLINED WALKING

The purpose of this study was to examine the effect of hiking shoes and hiking boots on the biomechanical responses to a stepping task and physiological responses to an inclined walking task. Participants (n = 16) performed six two minute stepping trials at a stepping rate of 72 bpm; three trials in hiking boots and three trials in hiking shoes. Following the stepping task, participants (n = 19) walked at 3.0 mph and 10% grade for five minutes in hiking shoes and hiking boots. Lower limb joint angles and moments were calculated using Visual 3D. Physiological data was averaged over the last three minutes of the stepping task to determine mean variables during steady state exercise. Results showed that during the lowering phase of the stepping cycle, ankle ROM and ankle and knee moments were significantly greater in hiking shoes than hiking boots, indicating that no compensatory mechanisms of the knee and hip were implemented due to restricted ankle ROM. Additionally, VO2 and VE were significantly greater in the hiking shoe condition during the inclined walking task. While these variables are statistically significant, they may not be practically significant in an actual hiking scenario, as the magnitudes of differences observed in variables were minimal. Use of either shoe or boot may not result in an increased risk of injury, therefore leaving the choice of footwear up to the hiker’s personal preference

Development of an upwind sailing ergometer

Purpose: To develop a sailing ergometer that accurately simulates upwind sailing exercise. Methods: A sailing ergometer that measures roll moment accompanied by a biofeedback system that allows imposing a certain quasi-isometric upwind sailing protocol (ie, 18 bouts of 90-s hiking at constantly varying hiking intensity interspersed with 10 s to tack) was developed. Ten male high-level Laser sailors performed an incremental cycling test (ICT; ie, step protocol at 80W + 40 W/3 min) and an upwind sailing test (UST). During both, heart rate (HR), oxygen uptake (VO2), ventilation (V-E), respiratory-exchange ratio, and rating of perceived exertion were measured. During UST, also the difference between the required and produced hiking moment (HM) was calculated as error score (ES). HR, VO2, and V-E were calculated relative to their peak values determined during ICT. After UST, the subjects were questioned about their opinion on the resemblance between this UST and real-time upwind sailing. Results: An average HM of 89.0% +/- 2.2% HMmax and an average ES of 4.1% +/- 1.8% HMmax were found. Mean HR, VO2, and V-E were, respectively, 80% +/- 4% HRpeak, 39.5% +/- 4.5% VO2peak, and 30.3% +/- 3.7% V-Epeak. Both HM and cardiorespiratory values appear to be largely comparable to literature reports during on-water upwind sailing. Moreover, the subjects gave the upwind sailing ergometer a positive resemblance score. Conclusions: Results suggest that this ergometer accurately simulates on-water upwind sailing exercise. As such, this ergometer could be a great help in performance diagnostics and training follow-up

An accurate model for genetic hitch-hiking

We suggest a simple deterministic approximation for the growth of the favoured-allele frequency during a selective sweep. Using this approximation we introduce an accurate model for genetic hitch-hiking. Only when Ns < 10 (N is the population size and s denotes the selection coefficient), are discrepancies between our approximation and direct numerical simulations of a Moran model noticeable. Our model describes the gene genealogies of a contiguous segment of neutral loci close to the selected one, and it does not assume that the selective sweep happens instantaneously. This enables us to compute SNP distributions on the neutral segment without bias.Comment: 12 pages, 10 figure
