In this study, we used competitive data to examine whether preceding high-intensity race efforts in a competitive weekend affects pacing behavior and performance in elite short-track speed skating. To do this, we

muscular sRPE-TL among PRO soccer players. These results suggest that reaching high sRPE-TL and TV during the preparation period might negatively affect strength and power properties. This phenomenon might be ascribed to a residual fatigue that exists due to the daily training (often 2 daily training

high-intensity exercise. 11 Owing to the potential impact of sodium bicarbonate on rowing performance, 8 , 12 – 15 a meta-analytical examination on its influence on the 2000-m test is warranted. In addition, it is still relevant to further analyze the impact of other substances that positively affect

The present study explored the perceived affect of personal and situational variables, perception of pain, and imagery ability on the function and outcome of an Olympic athlete’s use of imagery. To gain an in-depth understanding of these factors, semistructured interviews were conducted across three phases of injury rehabilitation, and return to competition. The athlete also completed the Athletic Injury Imagery Questionnaire-2 (Sordoni, Hall, & Forwell, 2002), the Vividness of Movement Imagery Questionnaire-2 (Roberts, Callow, Markland, Hardy, & Bringer, 2008), and the Visual Analogue Scale for pain (Huskisson, 1974). Findings highlight the perceived affects of personal and situational variables and imagery ability on the athlete’s responses to injury and function of imagery use. Further, this usage was perceived by the athlete to affect outcome depending on the phase of rehabilitation. Interestingly, perception of pain was not considered by the athlete to influence imagery use, this might have been due to the low pain rating reported.

bioimpedance analysis (BIA) in some clinical applications and physical activity is moderating physiological factors that affect its validity to monitor hydration. 6 These factors include increased cutaneous blood flow, elevated body temperature, accumulation of electrolytes on the skin, and elevated rates of

There has been considerable debate regarding the delivery and outcomes of games experiences in physical education. In particular, the relative benefits of the Teaching Games for Understanding (TGfU) approach have been compared to traditional skill-drill approaches to games teaching. However, many discussions of TGfU have focused on cognitive and psychomotor learning outcomes, neglecting the affective domain. The purpose of this article is to review TGfU research, to present an extended TGfU model, and to suggest new avenues for future research and practice. Future research directions include consideration of learning with respect to cognitive, behavioral, and affective characteristics.

negative slope with heavier loads was conditioned by a substantial lower sprint, RF max and V max . In addition, the results seem to indicate that the load increment on the vertical component might more negatively affect the RF max than the achieved V max , particularly when the load is higher than 20

Despite various contributing factors, session rating of perceived exertion has the potential to affect a large proportion of the global sporting and clinical communities since it is an inexpensive and simple tool that is highly practical and accurately measures an athlete’s outcome of training or competition. Its simplicity can help optimize performance and reduce negative outcomes of hard training in elite athletes.
