In focus: Benefits of Ice Slurry Consumption for Endurance Performance in Heat
Athletes competing in hot environments often face challenges related to elevated body temperatures, which can lead to fatigue and reduced performance. Recent findings emphasize the efficacy of ice slurry ingestion as a compelling strategy to enhance endurance under such conditions. For instance, studies indicate that ice slurry consumption can increase time to exhaustion by approximately 19% during submaximal running, leading to better performance outcomes compared to cold water intake (Ice Slurry Ingestion Increases Core Temperature Capacity). This effect is attributed to a combination of mechanisms: it effectively reduces pre-exercise core temperature, allows for greater heat storage during exercise, elevates the temperature at which fatigue onset occurs, and improves athletes’ perceived exertion ratings, enhancing their comfort levels while exercising in the heat.
Furthermore, the timing and method of ingestion play critical roles in optimizing these benefits. Research shows that consuming ice slurry after warm-up sessions can significantly lower core temperatures during exercise, thus improving endurance capacity (Effect of the timing of ice slurry ingestion). Additionally, combining ice slurry ingestion with external cooling strategies has resulted in notable improvements in power output during high-intensity events (Novel Precooling Strategy Enhances Time Trial Cycling in the Heat).
The practical implications for athletes and coaches are clear: incorporating ice slurry as a pre-cooling strategy can extend performance limits and delay fatigue, making it a practical alternative to traditional methods like cold water immersion. Overall, these insights suggest that leveraging ice slurry ingestion effectively aligns with the ongoing pursuit of optimizing athletic performance in extreme conditions, providing athletes with a tactical advantage during competitions.

Key finding:
Pre-exercise ice slurry ingestion reduces hyperventilation and may enhance endurance performance in heat, despite gastrointestinal side effects.
How they did it:
Methodology: 12 healthy male participants ingested either an ice slurry (7.5 g/kg body weight) or a control drink at 37°C in a heat environment (35°C) before performing a moderate-intensity cycling exercise followed by high-intensity cycling until exhaustion.
Results: The ice slurry significantly reduced esophageal, rectal, and gastrointestinal temperatures throughout moderate-intensity exercise (all P < 0.05). Additionally, minute ventilation was lower while cerebral blood flow index was higher in the ice trial (both P ≤ 0.042).
Innovations: The study utilized a novel approach of pre-exercise ice slurry ingestion to mitigate hyperventilation and cerebral hypoperfusion, aiming to enhance high-intensity endurance performance under heat stress conditions.
Additional Findings: While the duration of high-intensity exercise did not reach statistical significance between trials (P = 0.160), 8 of 10 participants achieved longer durations in the ice trial, showing a moderate effect size (r = 0.47).
Gastrointestinal Discomfort: Participants reported greater subjective severity of diarrhea and stomachache after the ice slurry (both P ≤ 0.041), indicating potential adverse effects that could counterbalance the performance benefits.
Why it matters:
These findings illustrate that pre-exercise ice slurry consumption can effectively lower core temperatures, which may alleviate hyperventilation and enhance cerebral blood flow during endurance events in hot conditions. With an observed moderation in exercise ventilation and a tendency for improved performance duration in the heat, coaches and athletes can consider incorporating ice slurry into their hydration strategies for more efficient and less taxing training sessions.

Key finding:
The TALENT project establishes standardized guidelines for identifying and supporting young athletes in balancing education and sports careers.
How they did it:
Methodology: The study included 150 participants from diverse countries (Greece, Italy, Serbia, Bosnia and Herzegovina, Cyprus, and Croatia) who were educators (77 teachers) and coaches (73 coaches) involved in talent identification for student-athletes, utilizing 12 focus groups followed by workshops for validation of standards.
Results: A total of 41 statements emerged as guidelines for talent identification, with 20 oriented towards teachers emphasizing a multidisciplinary approach, and 21 focused on coaches highlighting the importance of psychological readiness and collaboration with educational institutions.
Statistical Insights: The focus groups revealed major themes such as the urgent need for standardized identification methods (score of 7% relevance), the necessity for more structured training for educators and coaches (score of 6%), and the recognition of infrastructure improvements as critical (score of 9%).
Innovations: The research introduced a structured set of shared standards for talent recognition and dual career support, aiming to unify efforts among stakeholders like coaches, teachers, and parents to better support young athletes navigating sports and education.
Implications: The findings pointed to a systematic need for dual career programs and improved communication among schools, sports clubs, and families, suggesting these elements as vital for reducing dropout rates in both education and sports contexts.
Why it matters:
The findings from the TALENT project offer essential insights for coaches and educators in identifying and nurturing young athletes. With a consensus on 41 key statements from teachers and coaches, including the importance of early talent recognition and collaboration with families, this research lays a practical foundation for streamlined approaches tailored to individual athlete needs. By implementing these standards, coaches can better support dual career paths, ultimately fostering not just sporting talent but also academic and personal growth.
