“Non-Invasive Investigation On Heart Rate Variability And Energy Expenditure During Competition And Physical Activity Of Chess Players”, 2021 (; backlinks):
A chess game represents a legitimate psychophysiological stress and it is a challenging and high cognitive demand task that requires full attention and energy over the course of the game. In order to monitor performance of chess players, one of the most popular psychophysiological markers is the heart rate variability (HRV) to date ( et al 2018).
Alongside with the HRV parameters, heart rate (HR) can also be used as a non-invasive measure of calorie expenditure for chess players to monitor their performance. Therefore, the aim of present study was to compare the HRV and calorie expenditure of chess players before-during-after the chess competition and running exercises.
The sample group consists of 10 volunteer men and women between the ages of 15–40 who have been playing chess regularly for at least 5 years. According to the physical activity readiness survey (FAHOA), healthy chess players were included in the current research. The participants’ chess competition and running exercises took place in 3 different time periods; HRV and HR values were taken before (15 min), during (30 min) and after (15 min). HRV, HR and body composition were obtained from the participants.
According to the results of the present study, there was a statistically-significant difference between HRV [RR (ms)] before (742.5 ± 115.3), during (730.8 ± 151.1) and after (794.5 ± 126.8). In addition to this, there was a statistically-significant difference was found between the calorie expenditure (138.1 ± 65.8 kcal) [near-identical to et al 2009] during the chess game and the calories (260.5 ± 109 kcal) spent during the running exercise.
Results: show that running exercise causes more energy consumption than chess competition. In conclusion, psychophysiological measurements have an impact on the monitoring chess players’ performance.
