OBJECTIVE: An effective training plan is an important factor in sports training to enhance athletic performance. A poorly considered training plan may result in injury to the athlete, and overtraining. Good training plans normally require expert input, which may have a cost too great for many athletes, particularly amateur athletes. The objectives of this research were to create a practical cycling training plan that substantially improves athletic performance while satisfying essential physiological constraints...

The automatic classification of sub-techniques in classical cross-country skiing provides unique possibilities for analyzing the biomechanical aspects of outdoor skiing. This is currently possible due to the miniaturization and flexibility of wearable inertial measurement units (IMUs) that allow researchers to bring the laboratory to the field. In this study, we aimed to optimize the accuracy of the automatic classification of classical cross-country skiing sub-techniques by using two IMUs attached to the skier's arm and chest together with a machine learning algorithm...

Maintaining a positive iron balance is essential for female athletes to avoid the effects of iron deficiency and anaemia and to maintain or improve performance. A major function of iron is in the production of the oxygen and carbon dioxide carrying molecule, haemoglobin, via erythropoiesis. Iron balance is under the control of a number of factors including the peptide hormone hepcidin, dietary iron intake and absorption, environmental stressors (e.g. altitude), exercise, menstrual blood loss and genetics. Menstruating females, particularly those with heavy menstrual bleeding are at an elevated risk of iron deficiency...

Quantification of the economic value provided by migratory species can aid in targeting management efforts and funding to locations yielding the greatest benefits to society and species conservation. Here we illustrate a key step in this process by estimating hunting and birding values of the northern pintail (Anas acuta) within primary breeding and wintering habitats used during the species' annual migratory cycle in North America. We used published information on user expenditures and net economic values (consumer surplus) for recreational viewing and hunting to determine the economic value of pintail-based recreation in three primary breeding areas and two primary wintering areas...

Daniel Anderson, James Nunn, Christopher J Tyler
The purpose was to compare 14°C (CWI14°C) and 5°C (CWI5°C) cold water immersion following intermittent running. On three occasions, nine male team-sport players undertook 12 min of CWI14°C, CWI5°C or non-immersed seated recovery (CON) following 45 min of intermittent running exercise. Maximal cycling performance and markers of recovery were measured before and in the 0 - 72 h after exercise. Peak power output (PPO) was immediately reduced following all interventions (d = 1.8). CWI5°C was more effective at restoring PPO than CWI14°C (d = 0...

Exercise-induced affect (EIA) has been well documented and is often composed of positive affect, negative affect, tranquility, and fatigue. Research on EIA has focused on mainstream sports such as running, walking, or cycling; however, no research has evaluated the influence of action sports participation in activities such surfing on EIA. The current study examined the effect of a single 30-min surfing bout on EIA in 107 adult volunteers. An additional purpose was if change in affect was similar based on surfing history, surfing frequency, and surfing skill level...
