Comparing Active, Passive, and Combined Warm-Ups Among Junior Alpine Skiers in -7°C

Before hitting the slopes: athlete and staff perspectives on warm-up and activation in high-performance snowsports

To explore warm-up and activation (W&A) practices in high-performance snowsports to describe their importance, application and potential improvements based on the perspectives of elite-level athletes and staff members. Qualitative study consisting of semistructured interviews with 13 international elite-level athletes, on-snow coaches, strength and conditioning coaches, sports physiotherapists and sports psychologists from different snowsports and subdisciplines: alpine skiing, freestyle skiing (park and pipe, aerials, moguls) and snowboarding (park and pipe, snowboard cross). The interviews were transcribed verbatim and analysed based on the principles of grounded theory. The main themes raised by the participants were (1) the importance of readiness for sports participation as the motive for W&A, (2) how readiness is reached with a structured W&A routine and (3) the different athlete-specific, task-specific and environmental-specific factors for optimal W&A. Athletes and staff members considered W&A an essential measure to get physically and mentally ready for sports participation. Being ready was described as a key factor for performance and injury prevention. For these athletes, adherence to W&A was the result of a process of experiencing the beneficial effects of W&A and learning from sustaining one or more injuries. Broad implementation of basic physical and mental W&A at the youth level was considered an important measure to increase the overall adoption of W&A as an inherent part of training and competition. At the elite level, W&A is performed to reach athletes' mental and physical readiness for performance enhancement and injury prevention. W&A is acknowledged as a complex and dynamic programme and is typically adapted to sport-specific demands, injury risks, environmental circumstances and individual needs and preferences. Overall, this study provides valuable contextual insights into the complexity of W&A and the factors that need to be considered to make sport-specific recommendations.

Revisiting the 'Whys' and 'Hows' of the Warm-Up: Are We Asking the Right Questions?

The warm-up is considered beneficial for increasing body temperature, stimulating the neuromuscular system and overall preparing the athletes for the demands of training sessions and competitions. Even when warm-up-derived benefits are slight and transient, they may still benefit preparedness for subsequent efforts. However, sports training and competition performance are highly affected by contextual factors (e.g., how is the opponent acting?), and it is not always clear what should be the preferred warm-up modalities, structure and load for each athlete and context. Further, we propose that the warm-up can also be used as a pedagogical and training moment. The warm-up may serve several different (albeit complementary) goals (e.g., rising body temperature, neuromuscular activation, attentional focus) and be performed under a plethora of different structures, modalities, and loads. The current commentary highlights the warm-up period as an opportunity to teach or improve certain skills or physical capacities, and not only as a preparation for the subsequent efforts. Moreover, the (justified) call for individualized warm-ups would benefit from educating athletes about exploring different warm-up tasks and loads, providing a broad foundation for future individualization of the warm-up and for more active, engaged, and well-informed participation of the athletes in deciding their own warm-up practices.

Practicing Sport in Cold Environments: Practical Recommendations to Improve Sport Performance and Reduce Negative Health Outcomes

Although not a barrier to perform sport, cold weather environments (low ambient temperature, high wind speeds, and increased precipitation, i.e., rain/water/snow) may influence sport performance. Despite the obvious requirement for practical recommendations and guidelines to better facilitate training and competition in such cold environments, the current scientific evidence-base is lacking. Nonetheless, this review summarizes the current available knowledge specifically related to the physiological impact of cold exposure, in an attempt to provide practitioners and coaches alike with practical recommendations to minimize any potential negative performance effects, mitigate health issues, and best optimize athlete preparation across various sporting disciplines. Herein, the review is split into sections which explore some of the key physiological effects of cold exposure on performance (i.e., endurance exercise capacity and explosive athletic power), potential health issues (short-term and long-term), and what is currently known with regard to best preparation or mitigation strategies considered to negate the potential negative effects of cold on performance. Specific focus is given to "winter" sports that are usually completed in cold environments and practical recommendations for physical preparation.
