From Heart-Rate Data to Training Quantification: A Comparison of 3 Methods of Training-Intensity Analysis

“…No study since has systematically quantified TID derived from three different methods in highly trained athletes. The TID of endurance athletes has received increased attention in both descriptive [1][2][3][6][7][8][9][10][11][12][13]18,20 and experimental studies [21][22][23] as well as recent reviews 24,25 . Because these three methods are used interchangeably there can be confusion regarding interpretation of training data, although the problem has been discussed 12 .…”

“…However, quantifying training dose remains an area of some confusion. Focusing on endurance athletes, training dose can be measured in terms of external work executed (distance, power, velocity) [1][2] , or internal physiological responses elicited by that work (heart rate, blood lactate, VO 2 ) [3][4][5][6][7][8][9][10][11][12][13] . Training dose can also be measured by how the stimulus was perceived (session RPE) 12,[14][15][16][17][18] .…”

“…Most high-level endurance athletes maintain a training diary where they report their training. In reality, some combination of all three of these basic descriptions of the training dose is usually reflected in athlete self-report [1][2][3][6][7][8][10][11][12]19,20 . Three basic approaches are described in the literature for quantifying endurance training sessions based on the heart rate (HR) response.…”

“…Tuttavia, questo utilizzo sembrerebbe dare delle risposte attendibili solo in presenza di esercizi a carico costante (i.e., steadystate) e non intermittenti. Questo perché (i) solo la relazione tra consumo di ossigeno ed un lavoro a carico costante risulta essere lineare (Robinson, Robinson, Hume & Hopkins 1991) ed (ii) in presenza di un carico di lavoro al di sotto della soglia lattacida, il consumo di ossigeno cresce in maniera esponenziale fino ad un livello costante, ma quando si è in presenza di un carico sopra la suddetta soglia la sua cinetica diventa maggiormente complessa (Xu & Rhodes 1999).…”

“…Tuttavia se i fattori che potenzialmente influenzano la frequenza cardiaca come la variabilità giornaliera, il livello di allenamento, le condizioni ambientali, la durata dell'esercizio, lo stato d'idratazione, l'altitudine e i farmaci sono controllati, l'accuratezza con la quale la frequenza cardiaca può essere usata come marker dell'intensità dell'esercizio aumenta Lambert, Mbamba & St Clair Gibson 1998;Robinson et al, 1991).…”
