Abstract
The present study examined exercise affect during volume-load matched, high-velocity, low-load and
low-velocity, high-load resistance exercise conditions in older adults. Ten older adults completed three
sets of eight exercises on six separate occasions (three high-velocity, low-load and three low-velocity,
high-load sessions) in a crossover study design. High-velocity, low-load was performed at 40% of
predicted one repetition maximum, and low-velocity, high-load at 80%. The Physical Activity Affect
Scale, Felt Arousal Scale, Feeling Scale, Rating of Perceived Exertion, Visual Analogue Scales, and the
Physical Activity Enjoyment Scale examined exercise intensity and affect. There were moderate effects
of exercise condition on positive exercise affect (P = 0.067; η2
P = 0.33), and trivial effects on negative
exercise affect (P = 0.904; η2
P = 0.002). Rating of perceived exertion (P < 0.001; η2
P = 0.41) and fatigue
(P = 0.012; η2
P = 0.52) were greater during low-velocity, high-load. Furthermore, high-velocity, low-load
facilitated statistically insignificant, favourable changes (less exertion, more enjoyment etc.) for all other
measures. These findings combined with emerging evidence that high-velocity, low-load is superior for
improving muscle power and/or functional performance, indicates that high-velocity, low-load should
be prescribed preferentially. However, both exercise conditions were enjoyed similarly, demonstrating
that individual preference is an important consideration.
