AF affects the performance of the heart, especially amongst older, less healthy people. But it also affects a significant percentage of Masters athletes. A large study over a 20 year period shows an interesting correlation between Atrial Fibrillation (AF) and HRV. There are optimum values of HRV and resting heart rate, above and below which the chances of developing AF increase significantly.
Government guidelines in the UK suggest no more than 14 units per week, equivalent to a standard glass of wine or a pint of lower strength (4%) beer every day for maintaining health. But do these suggestions also apply to athletes in training?
Is HIIT a better use of your precious training time than longer sessions of continuous running? An important question for runners is ‘am I more likely to get injured with one type or the other?’
HRV has been recognised as an index of stress and vulnerability to stress, so it’s no big surprise that researchers have been looking for possible relationships between higher HRV and a longer lifespan.
It is very important to take into account the trends reported by both the Week and Month Change indications, as these are the ones that will report an increasing and unsustainable imbalance between stress and recovery.
Despite a great deal of discussion about, and anecdotal evidence to support the benefits of a low carbohydrate high fat (LCHF) diet, there have been few studies examining the degree to which athletes’ metabolisms have been altered to take advantage of this dramatic change in fuel for exercise.
PhD candidate Angela Spontelli Gisselman PT, DPT, OCS details the who, what and why of her own recent research in to overuse injuries and the ANS.

Following on from last month, July has been quite a stressful month for John O’Regan with his training being very intermittent Did John manage to finish July strongly?
Summarising a very interesting piece of research looking at predicting team sports performance using heart rate variability (HRV).
Using the Framingham data this paper focuses on heart rate variability (HRV) and resting heart rate as predictors of cardiovascular disease, type-2 diabetes, and the so-called metabolic syndrome that also includes obesity and blood fat levels.
Our latest research summary takes a look at a case study of heart rate variability (HRV) in two elite triathletes, one successful, one overtrained

Research summary of an intelligent study trying to understand the relationship between daytime heart rate variability (HRV), HRV response to periods of worry and sleep disturbance.
Researchers at the University of Salzburg, Austria and the University of California wanted to test the idea that if daytime heart rate variability (HRV) is strongly linked to physical and mental health, would HRV also be a predictor of healthy sleep?
This is an interesting study that suggest that HRV has the potential to deliver a sport independent comparable training load number, a goal long sought after by sports scientists and coaches.
