 note = {To assess physical load of doubles soft tennis match, heart rate was measured in male college students. Sixteen soft
tennis players belonging to the college sports club, aged 19 to 22 years, took part in the measurement. They were at a level
of competing for the top of local tournaments. A bracelet type receiver was mounted on the wrist of the subject and the
heart rate sensor was attached to the chest using the strap as a transmitter. A total of 13 matches were held in the outdoor
court through September to October. As a result, exercise intensity during the doubles soft tennis match was between 140
and 150 beats/min with an average heart rate, corresponding to approximately 60% of Vo2max. Soft tennis was considered
to be a little stronger in exercise intensity than tennis played with a hard ball. Multiple times of the matches showed that
there was no difference in exercise intensity between forward and back players. Comparing service and return games, it was
found that significantly higher heart rate values during service than in return games, especially the trend was clear in back
players. Heart rate during tennis match would be also somewhat influenced by other conditions such as competition level,
tactics, sex, and age.},
