Results from a study in Costa Rica show that wearing water-resistant SPF50 sunscreen during prolonged exercise in hot conditions can result in a small but significant increase in core body temperature (~0.2°C) and greater thirst while skin temperature and body mass loss remain unchanged.

The findings highlight an important consideration for athletes and outdoor workers: balancing essential sun protection with effective heat management during prolonged activity in hot environments.

Analysis of a Canadian clinical trial shows both high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) may help reduce hypertensive responses to exercise. Notably, a greater proportion of participants achieved a clinically meaningful reduction in peak systolic blood pressure following MICT compared with HIIT (43% vs 19%).

The findings highlight the importance of monitoring individual blood pressure responses and tailoring exercise prescription for people living with atrial fibrillation.

Measuring physical activity in toddlers is challenging, with their unique movement patterns limiting the accuracy of traditional accelerometer methods.

A research team in Canada developed machine learning models that more accurately distinguish physical activity, sedentary time and non-volitional movement in toddlers, outperforming many existing methods.

Importantly, the researchers also developed an open-access, no-coding-required tool, making these models accessible to researchers and clinicians and supporting more accurate links between toddler movement, health outcomes and physical activity guidelines.

This study evaluated the reliability and sensitivity of sprint and step-test protocols for monitoring aerobic and anaerobic performance in swimmers and triathletes.

The findings support the 3-minute step test as a highly reliable tool, particularly for lactate-based intensity markers such as vLT1, vLT2 and peak swimming speed, helping detect small but meaningful changes in performance. In contrast, the 20-second sprint test showed only moderate reliability and requires further refinement before routine diagnostic use.

The study also suggests lactate-based thresholds may provide more reliable guidance for training intensity prescription than heart rate measures.

A nine-year study examining professional and amateur racing found that injury risk varied considerably across the industry. Amateur jockeys had the highest fall incidence, jump jockeys the highest overall injury incidence, while flat jockeys faced the greatest risk of injury following a fall.

Encouragingly, injury rates decreased in professional racing between 2016 and 2024, potentially reflecting the impact of new safety interventions. However, the high proportion of fractures and concussions among amateur jockeys highlights the need for more targeted injury prevention strategies in amateur racing.
