effect ( McGowan, Pyne, Thompson, & Rattray, 2015 ). Physical warm-up activities can literally warm the muscles of athletes and prime the body systems involved in sport tasks that follow. Some physical warm-ups can also serve as a “microdose” of strength-and-conditioning exercise that can reduce the risk

Warming up is widely considered an effective performance-enhancing strategy, with several potential mechanisms being proposed, such as increases in muscle temperature, metabolic rate (through an accelerated oxygen supply to muscles), or nerve conduction rate, as well as psychological benefits. 1

, 4 – 7 large increases in T c during WRSS match play (eg,  T c  > 39°C) may limit physical performance. 1 A WRSS tournament day is typically characterized by 3 matches in close proximity (∼3 h between matches) and ∼20 to 30 minutes allocated for a team to warm-up prior to each match. 1 The warm-up

standardized warm-up (see “Methods” section). Previous studies using the previously mentioned warm-up protocol have assessed the relationship between FTP and other markers of the steady to nonsteady state transition, such as the lactate 4 or individual anaerobic threshold, 5 or the MLSS, 6 showing at best

Cycling coaches and athletes are constantly searching for intervention strategies to improve race performance. It is widely acknowledged that an appropriately implemented warm-up strategy can substantially benefit cycling performance by increasing muscle temperature, speeding up oxygen uptake

The athletic warm-up consists of a set of low- to moderate-intensity exercises designed to increase muscle temperature, cellular metabolism, and range of motion 1 to help players reach their optimum performance during sporting activities 2 and to mitigate the risk of injury. 3 Although past

Purpose:

The purpose of this project was to observe current warm-up practices in snowboard athletes and evaluate their physiological impact before competition.

Methods:

An observational design was used to monitor 4 athletes (2 female) at an Open National Snowboard Cross Championships. Activity patterns, core temperature, heart rate (HR), and time between warm-up and competition were measured. Athlete ratings of thermal comfort (TC) and thermal sensation (TS) were recorded before competition.

Results:

Significant barriers and challenges to an optimal warm-up included delays, environment, and logistics. Time gaps between structured warm-up and competition start time were in excess of 1 h (median = 68.8 min). Median average HR for 10 min (HR10) did not exceed 120 beats/min in the hour preceding competition, suggesting a suboptimal warmup intensity. Athletes rated their TC between comfortable and slightly uncomfortable and TS as neutral to slightly warm before the start of qualifications and finals.

Conclusions:

The observations of this project suggest significant gaps in current warm-up strategies used in snowboarding. These include inadequate general aerobic warm-up (based on intensity and duration), excessive time between warm-up and competition, and lack of a consistent and structured warm-up protocol. Future work is needed to evaluate the effectiveness of different warm-up strategies on muscle temperature and performance while determining the optimal length of time between warm-up and competition.
