The purpose of this study was to compare the muscular
strength and endurance of thirty-two men 51 to 79 years of age who
engage in weight training (WT), aerobic training (AT), cross training
(CT), or no training (S). The design employed in the study was a 2x2
between subjects factorial design with weight training and aerobic
training as the two factors. A KIN/COM isokinetic dynomometer was
used to test muscular strength and endurance of the dominant leg
extensors and chest/shoulder complex. Strength of the leg
extensors and chest/shoulder complex were measured as peak torque
and peak force, respectively, at a velocity of 60 degrees/second.
Endurance of the same muscle groups was measured as the percent
decline over 50 continuous maximal contractions at a velocity of
180 degrees/second.
A two-way between subjects ANOVA and independent t-tests
were used to analyze the difference between mean muscular
strength and mean muscular endurance for each group. A significant
weight training effect was found for leg strength, with the WT and
CT groups (Weight Trained groups) exhibiting a greater peak torque
than the AT and S groups (Non-Weight Trained groups). Participating
in one of three training programs was found to have a significant
effect for chest and shoulder strength, with the WT, CT, and AT
groups exhibiting a greater peak force than the S group. However, no
significant difference was found between the WT, CT, and AT groups
for chest/shoulder strength. The WT group was found to have
significantly greater muscular endurance of the leg compared to the
S group. No other training effects were observed between any of the
groups for either muscular endurance test. / Graduation date: 1992
