Background: Acute sarcopenia is sarcopenia lasting less than 6 months, typically following acute illness or injury. It may impact patient recovery and quality of life, advancing to chronic sarcopenia. However, its development and assessment remain poorly understood, particularly during hospitalisation.

- - The study evaluated the reliability of a method called detrended fluctuation analysis of heart rate variability (DFA-α1) for determining exercise intensity thresholds and compared it to traditional methods based on blood lactate and gas exchange for a group of 37 participants.
- - Test results showed that DFA-α1 had good reliability and moderate agreement with the other two methods, although the accuracy of thresholds varied depending on participants' cardiorespiratory fitness levels.
- - The findings indicated that male participants had a higher bias in threshold measurements compared to females, and to improve DFA-α1 accuracy, adjustments should be made based on both sex and fitness levels.
Article Synopsis
- A study was conducted with 13 female netball players over 14 days to assess their energy and fluid needs during matches and training.
- The findings showed that total energy expenditure (TEE) was significantly higher on match days compared to training and rest days, with mean TEE at 13.46 MJ per day.
- The research aims to provide dietary guidance for female netball players based on their assessed energy and fluid turnover, which was highest on match days.
Fatty acids are stored within the muscle as intramyocellular lipids (IMCL). Some, but not all, studies indicate that following a high-fat diet (HFD), IMCL may accumulate and affect insulin sensitivity. This systematic review and meta-analysis aimed to quantify the effects of an HFD on IMCL.

- The study aimed to assess the accuracy of an iPhone® pedometer compared to a traditional pedometer in adults with and without asthma during specific walking tests and in free-living conditions.
- Ten adults with asthma and ten healthy participants were tested on a treadmill and during self-paced walks, with their step counts measured using different pedometer placements and a manual video count as a reference.
- Results showed that the iPhone® pedometer performed well, particularly when worn on the lower body, suggesting it could be a reliable tool for tracking physical activity in both populations, but further research is needed for conclusive results.
Cardiorespiratory fitness levels and their association with cardiovascular profile in patients with rheumatoid arthritis: a cross-sectional study.
Rheumatology (Oxford)
December 2015
Objective: The aim of this study was to investigate the association of different physical fitness levels [assessed by the maximal oxygen uptake (VO2max) test] with cardiovascular disease (CVD) risk factors in patients with RA.
Methods: A total of 150 RA patients were assessed for cardiorespiratory fitness with a VO2max test and, based on this, were split in three groups using the 33rd (18.1 ml/kg/min) and 66th (22.
Rheumatoid arthritis (RA) is a chronic inflammatory disease associated with significant functional impairment and increased risk for cardiovascular disease. Along with pharmacological therapy, exercise seems to be a very promising intervention to improve disease-related outcomes, including functional ability and systemic manifestations, such as the increased cardiovascular risk. In this review, we discuss the physiological mechanisms by which exercise improves inflammation, cardiovascular risk and psychological health in patients with rheumatoid arthritis (RA) and describe in detail how exercise can be incorporated in the management of this disease using real examples from our clinical practice.
