| dc.description.abstract | The study was conducted to exmine potential long term
ef--ectu of marihuana upon the cardiovascular system before,
duling, and after submaximal exercise. TRe following specific
s=diovascular parameters were used to compare long term
marihuana users to non-users,
1) Resting heart r a t e and blood pressure
2) Exercise heart rate, blood pressure, and ECG
cha~ges
3) Immediate post-exercise heart rate, blood pressure,
and ECG changes a t two, four, and six minute
intervals
4) Time on the treadmill to reach the exercise level
of the target heart rate,
The two samples consisted of 23 computer matched pairs
Bekwaen the ages of 17 and 21, The subjects were solicited
frm the Personal Health and General Psychology classes offered
i n the curriculum at: the University of Wisconsin-La Crosse,
The screening and testing procedures were conducted over a
g e ~ i o de f two marther.
'Phe statiatieal. male1 used i n t h i s study was the paired
t @eat. The five percent level of confidence was the c r i t i c a l
s t ~ t i s t i c a lv alue ehoeen f o r acceptance or r e j e c t i o n of the
nuLL hypathesls,
Significant differences between the marihuana users and
nen-users were found i n heart rate and d i a s t o l i c blood pressure
during the post-exercise periodo The users' heart rate was
significantly lower than the non-users a t four minutes past
exercise. A t four and six minutes post exercise the users'
diastolic bl-d prsss8=e was significantly higher than the
non-users. There were no signifacant long term effects of
marihuana on the resting cardiovascular parameters. The long
term use of marihuana does not r e s u l t i n any apparent ECG
changes. | en |
