An adequate level of cardiorespiratory fitness (CRF) is critical for firefighters to perform the strenuous and physiologically demanding work of firefighting safely and effectively.   The coronavirus disease 2019 (COVID-19) has been shown to negatively impact CRF in both the acute phase and longer-term following infection. This study aimed to determine changes to the CRF of firefighters pre-...

The study aims to compare ventilatory and cardiorespiratory responses between the COSMED Aquatrainer coupled with the K4b2 and K5 wearable metabolic systems in breath-by-breath mode over a wide range of swimming speeds.   Swimming with the AquaTrainer coupled with K5 (breath-by-breath mode) yields accurate, precise, and repeatable ventilatory and cardiorespiratory responses when compared with...

Since the outbreak of COVID-19, there have been cases of prolonged symptoms, known as post-acute or chronic COVID-19 (long COVID). Detecting underlying causes of persistent symptoms in these patients can be challenging. In this recent report published in International Heart Journal, authors detail a 39-year-old male with excessive body weight and a history of borderline values of arterial...

The evidence that cardiorespiratory fitness (CRF) predicts morbidity and mortality independent of commonly obtained risk factors isbeyond dispute.   Observations establishing that the addition of CRF to algorithms for estimating cardiovascular disease risk reinforcesthe clinical utility of CRF.   Evidence suggesting that non-exercise estimations of CRF are associated with all-cause mortality...
