Wasted days and wasted nights
Published in James Kennaway, Rina Knoeff, Lifestyle and Medicine in the Enlightenment, 2020
Helping usher in this new “reality” was John Floyer, a seventeenth-century practitioner of traditional Galenic dietetic medicine who lived and breathed regimen. He brought to the ancient art of taking the pulse a new instrument of his own design, a chronometer which measured time not just by hours and minutes but even by seconds, and which had a lever for stopping the movement of the seconds hand – the first “stop watch,” as it were (see Figure 9.1). Floyer commissioned the distinguished horologist Samuel Watson to build the “pulse-watch” sometime around 1695, and then spent the next decade counting his own pulse and the pulse beats of his patients at Litchfield hospital, meticulously keeping records and assembling tables. He published the results of his study in The physician’s pulse-watch; or, an essay to explain the old art of feeling the pulse and to improve it by the help of a pulse-watch (1707).

Pendulum [Latin: pendere, to hang] Galileo Galilei (1564–1642) of Pisa is credited with the invention in 1639. He first observed the principle from the oscillations of a suspended lamp in the cathedral at Pisa in 1583. His observation that the oscillations were equal in time whatever their range led to its use for measuring time. The principle was employed by Sanctorio Sanctorius (1561–1636) to develop a pulse watch.

All the cycling patients performed an aerobic training program on a MOTOmed viva2 leg trainer (RECK-Technik GmbH & Co. KG, Betzenweiler). Each training session consisted of 30 min of active cycling varying from interval to continuous. Heart rate training zones were calculated using the below formula: [heart rate peak − heart rate rest] X [60–75%] + heart rate rest [26], where peak and rest heart rate were determined in a maximal graded exercise test. Each training session a chip card was put into the MOTOmed leg trainer. Patients were asked to cycle at the proposed heart rate training zone. The heart rate was monitored by a polar pulse watch and chest strap (Polar pulse watch and chest strap; Polar Electro Oy, Finland). At the beginning and end of each training session both legs were passively moved by the MOTOmed trainer during the five minutes session.

On arrival, the participants were outfitted with a pulse watch to ensure a wireless heartrate (HR) and heartrate-variability (HRV) transfer. For all participants, an intravenous catheter was used (at −60 min; meaning 60 min before stress induction) to obtain blood samples before and after the stressor: two samples before (−15 min; −1 min) and eight samples after each stressor (+1 min; +5 min; +10 min; +20 min; +30 min; +45 min; +60 min; +75 min; Figure 1 and 2) during which eight mL of venous blood were collected using a Monovette-system. Furthermore, the HR and the HRV were measured at selected moments: two before, two during, and two after stress induction. To assure an identical baseline, standardized breathing at rest prior to stress induction was performed with each participant (3 sec/breath).
Effects of rhythmic auditory stimulation on walking during the 6-minute walk test in patients with generalised Myasthenia Gravis

The patient’s heart rate (HR) was measured by a pulse watch (Suunto Quest, model SS018153000). The average HR was calculated by the pulse watch, based on all the HR’s measured over the entire 6min. Patients were asked beforehand to refrain from caffeine-containing beverages and smoking on the test day, to reduce the influence on HR. After each of the walk tests, patients were asked to determine ‘how exhausting did you find the test?’ on the Borg Scale of Perceived Exertion [25], where they could state their subjective experience of exhaustion from 6 (‘very, very easy’) to 20 (“very, very exhausting).
