Achievements and capabilities influence the self-esteem of skilled adventure athletes. Self-esteem affects individual mental health. Aging commonly reduces adventure capabilities. To avoid loss in self-esteem, aging adventure athletes are forced to adjust their aspirations. Here, I examine this process using participant observation, ethnographic and autoethnographic approaches. The qualitative data for this analysis are derived from 60 years' experience in outdoor adventure activities, and ∼30,000 person-hours of participant observation...

This study was divided into two complementary parts. In Part 1, we proposed a novel paddle strokes analysis based on the force signal from a 30-s all-out tethered test; and compared these results with video recordings. In Part 2, we investigated the relationship between force data from the same test with paddle stroke results from both methods. Eleven male elite slalom kayakers (Brazilian national team) were evaluated. The tethered test was conducted for force parameters analysis (peak-force, mean-force, impulse)...

This paper proposed a novel real-time compression load measurement system for a kayaking paddle based on optical fiber technology. The optical fiber sensor, fiber Bragg grating, is embedded in a 2 mm polydimethylsiloxane membrane, which serves as a pressure mat that can be easily attached/detached to/from the kayaking paddle. The proposed system is proposed for measuring and evaluating both handgrip loading and paddle blade load distribution during on-water kayaking, e.g., peak compression load distribution pattern and duration of the paddle blade in real time...

Traditionally, physical and anthropometrical profiles of the most successful kayak athletes have been identified in male kayakers. This study attempted to identify the differences in morphology and fitness level of two performance-based groups of young elite female paddlers. Eighty-six female kayakers, aged 13.62 ± 0.57 years (mean ± SD) were allocated in two groups (Top-10 and Rest) depending on their ranking in the three Olympic distances (200, 500 and 1000 meters). All subjects underwent a battery of anthropometrical (heights, weight, girths and sum of skinfolds), physical fitness (overhead medicine ball throw, countermovement jump, sit-and-reach test and 20-m multistage shuttle run test) and specific performance assessments (200, 500 and 1000 meters)...

During competition, kayak athletes must optimally adapt to environmental factors (e.g. wind, waves) to achieve peak performance. However, the ability to adapt to such perturbations has never been assessed in kayak paddling. Therefore, the aim of the current study was to evaluate the local dynamic stability in sports technique of youth sprint kayak athletes. In a cross-sectional study, 14 healthy male athletes were recruited from an elite youth sprint kayak squad. During an incremental kayak ergometer test, mean power, heart rates and local dynamic technique stability of hands, arms, trunk and paddle were registered and the association with the athletes 2000 m free-water times were estimated using mixed models...

Current training and monitoring methods in sprint kayaking are based on the premise that upper-body muscular strength and aerobic power are both important for performance, but limited evidence exists to support this premise in high-level athletes. Relationships between measures of strength, maximal oxygen uptake (VO2max) and 200-m race times in kayakers competing at national-to-international levels were examined. Data collected from Australian Canoeing training camps and competitions for 7 elite, 7 national and 8 club level male sprint kayakers were analyzed for relationships between maximal isoinertial strength (3-RM bench press, bench row, chin-up and deadlift), VO2max on a kayak ergometer, and 200-m race time...

Brief, intense exercise training employing running and cycling as exercise interventions may induce aerobic and anaerobic adaptations in athletes from wide range of sports. However, this has not been studied extensively for those sports in which the upper-body is predominantly involved. Our purpose was to examine the effects of kayak paddling-based sprint interval training (SIT) on cardiorespiratory fitness and anaerobic performance. 16 professional female canoe polo athletes (age = 27.6 ± 1.9 years; height = 165...

The Sonic Kayak is a musical instrument used to investigate nature and developed during open hacklab events. The kayaks are rigged with underwater environmental sensors, which allow paddlers to hear real-time water temperature sonifications and underwater sounds, generating live music from the marine world. Sensor data is also logged every second with location, time and date, which allows for fine-scale mapping of water temperatures and underwater noise that was previously unattainable using standard research equipment...

Background High-risk sports, particularly climbing, kayaking and extreme skiing, have become increasingly popular. The most widely used psychological survey instrument with regard to risk behaviour in sports is the Sensation Seeking Model, mostly assessed by the Sensation Seeking Scale (SSS-V). Until recently, the literature discussed risk behaviour solely through this model. However, this scale does not measure risk-taking behaviours. In contrast, the Risk-Taking Behaviour Scale (RBS-K) is a three-item scale that measures risk behaviour in high-risk sports...

Using theoretical principles, the components of drag (friction DF, pressure DPR and wave DW) of a single-seat kayak were analysed. The purpose was to examine the effect of changes in wetted surface area due to changes in kayaker's weight and the relative contribution of DF, DPR and DW to the total passive drag as function of velocity. The total passive drag values were based on experimental data collected in a single-seat kayak. Three different kayaker simulated weights were tested - 65, 75 and 85 kg. DF was the drag component that contributed the greatest percentage (between 60 and 68% at 5...

PURPOSE: It was investigated if β-alanine supplementation counteracts muscular fatigue development or improves athletic performance. METHODS: Elite kayak rowers (10 males and 7 females) were supplemented with either 80 mg/kg body mass/day β-alanine or placebo for 8 weeks. Muscular fatigue development was investigated by applying a 2 min elbow flexor maximal voluntary contraction (MVC). Electromyography (EMG) was recorded continuously and voluntary activation (VA) was determined 30, 60, 90 and 115 s into the 2 min MVC...

Within the Paracanoeing discipline, it is important to ensure that appropriate control is achieved by a paddler with a disability. However, this Paralympic Games discipline has seen very little attention to date. The aims of this study were to understand the kinematic impact to a paracanoeist when not utilizing the use of a prosthetic lower-limb. A kayaker with a uni-lateral transfemoral amputation completed several 200 m maximal efforts both with and without their prosthesis. When the prosthetic limb was removed, there were significant differences found in stroke rate, stroke speed, stroke length and overall power output...

Chest wall injuries are common in paddle-based sports such as kayaking. We present the case of a 46-year-old amateur kayaker who presented with signs and symptoms in keeping with a rib stress response or fracture. The patient failed to respond to conservative management and subsequent imaging revealed an obstructed left kidney with associated hydronephrosis. This case report highlights the importance of considering the wider differential diagnoses when managing athletes participating in paddle-based sports, especially when symptoms fail to settle with appropriate conservative management...
