In this paper, we advocate a novel approach of representing physical activity in the form of
material artifacts. By designing such material representations, we aim to understand what …

The Karvonen formula, which is widely used to estimate exercise intensity, contains
maximum heart rate, HR max, as a variable. This study employed pedaling experiments to …

Many wearable devices include PPG (photoplethysmography) sensors for non-invasive
heart rate monitoring. However, PPG signals are heavily corrupted by motion interference …

Objective: Recently numerous methods have been proposed for estimating average heart
rate using photoplethysmography (PPG) during physical activity, overcoming the significant …

Self-monitoring devices are becoming increasingly popular in the support of physical activity
experiences. These devices mostly represent on-screen data using numbers and graphs …

Obesity is one of the biggest health problems globally that, together with sedentarism,
requires solutions that increase the enthusiasm towards physical activity. Therefore, this …

The purpose of current study is investigating effect of Blood Flow Restriction Interval Training
on aerobic performance among young football players during transition phase of …

This study aimed to analyze the effect of 12 weeks of polarized training on body
composition, cardiorespiratory function, and upper-body power of male and female cross …

Visualizing heart rate on screen has become popular to measure physical activity
performance and progress towards set health goals. However, we believe that this prevalent …

Navzdory vzrůstající popularitě běhu je literatury věnované běžeckému tréninku mládeže
stále nedostatek. Stejně tak málo pozornosti je věnováno běhu na výkonnostní, a nikoli …
