    Opis:
    Lactate threshold (LT) estimation in endurance sports continues to be a widely controversial field amongst sports scientists and students despite beyond 50 years of research. With the advent of technology and superior sensors, LT research has ventured into newer fields involving wearables and artificial intelligence. Still, there is a felt need to understand the focused areas of LT research and to guide the students, sports scientists and coaches. The main aim of this mini-review is to identify research categories in a descriptive manner and to synthesize broad themes for future research from latest literature. A comprehensive electronic search in three databases was performed including only original free full text research articles conducted in athletes and heathy subjects, published in English between 2016 and 2020 following PRISMA guidelines. Out of screened 466 articles, 14 articles were finally shortlisted as per inclusion criteria and the findings were summarized. Five research categories were identified and reviewed. To conclude, there is a need for consensus in Graded Exercise test protocols used, LT concepts validity for specific sports and the application of valid, reliable noninvasive LT estimation methods in endurance sports. Synthesized broad themes would help guide sports scientists, students and researchers for future research.

    Opis:
    Aim. The aim of this study was to measure aerobic demands of fire fighting activities including exercise in the heat. Methods. Twenty-two experienced firefighters performed the Trondheim test simulating fire fighting tasks including work in the heat. Maximal oxygen uptake (VO2 max), heart rate (HR) and ventilation were recorded continuously. Data were compared with results obtained during a treadmill test during which the participants were dressed as smoke divers. Results. The participants completed physical parts of the Trondheim test in ~12 min (range: 7.5–17.4). Time to complete the test was closely related to the participant’s VO2 max. HR of ~170 beats/min and pulmonary ventilation of ~100 L/min were higher than at lactate threshold (LT) during laboratory tests. VO2 averaged over the test’s physical part was 35 ± 7 ml/min/kg, which was at the same or below the level corresponding to the participants’ LT. Physically fit participants completed the test faster than less fit participants. Slower and physically less fit participants consumed more air and used more oxygen than faster and physically more fit participants. Conclusion. The Trondheim test is physically demanding; it distinguishes physically fit and less fit participants.
