| ABSTRACT | |||
| With regards to obesity-related disease the impact of exercise
training on health depends on the ability of exercise to promote a negative
energy balance. Exercise's effect on promoting a negative energy balance
is more likely to occur if exercise can induce a favourable dietary intake
such as a reduced relative fat content in the diet. As such, the aim of
this study was to evaluate and compare the effectiveness of aerobic training,
weight training and concurrent aerobic and weight training on self-reported
dietary intake. The effects of 16 weeks of aerobic (n = 12), weight (n =
13) and concurrent aerobic and weight training (n = 13) on self-reported
dietary intakes were compared in previously sedentary males using the computer-based
Dietary Manager® software programme. Only the concurrent aerobic and weight
training group showed significant (p < 0.05) reductions in total kilocalories,
carbohydrates, proteins and fats consumed while the aerobic training group
showed significant reductions in fat intake at the completion of the experimental
period (before: 91.0 ± 42.1g versus after: 77.1 ± 62.1g). However, no changes
were observed in self-reported dietary intake in the weight training or
non-exercising control groups. It is concluded that concurrent aerobic and
weight training is the most effective mode of exercise at promoting a favourable
improvement in self-reported dietary intake in the short term. This finding
provides support for efforts to promote increases in overall physical activity
in an attempt to modify the patterns of dietary intake.
