At the end of the chapter, a few unsolved exercises are given for practice and further investigation.
To allow for progression, three levels of difficulty are given for each exercise.
After a brief warm-up, an estimated load was given for each exercise (leg press, lateral pulldown, leg extension, chest press, leg curl, shoulder press, bicep curl, tricep press, and abdominal crunch), and each subject completed no fewer than 8 and no more than 15 repetitions.
In a recent study of 1,056 pregnant women in the third largest city in China, Tianjin, women expressed concern about the safety of exercise, with the most common reason given for not exercising during pregnancy being a fear of miscarriage [ 10].
Likewise, the most common reason given for not exercising during pregnancy in a Chinese sample was a fear of miscarriage [ 10], however, this is the first study to directly compare between cultures.
The general criterion, when given, for a positive exercise stress test result was uniform ST depression ≥1 mm.
"I'm too old to start," is one of the most common reasons they give for not exercising.
"One of the main reasons people give" for not exercising is that they don't have time, says Arnt Erik Tjonna, a postdoctoral fellow at the Norwegian University of Science and Technology, who led the study.
Lack of time is one of the most common reasons people give for not exercising or eating healthy food, yet few studies explicitly test its relationship with health behaviours.
