Abstract:
The benefits of participating in sports are well documented. Recent times have seen an
increase in the participation in contact sports and the seemingly accepted forms of
anger and aggression. Examples of these sports are kickboxing and rugby. Anger and
aggression, however, have a negative impact on wellbeing, and have been associated
with various psychological disorders. This poses the question: what are the effects of
accepted anger and aggression in sport on the wellbeing of the individual?
The specific aim of the present study is to explore the effects of the pro-social physical
expression of anger and aggression on psychophysiological wellbeing. This is
accomplished by measuring and comparing the psychological and physiological
wellbeing of males participating in kickboxing (n=18), males participating in rugby
(n=23) and males not participating in either (n=50). The participants,all of them South
Africans, were drawn from a kickboxing club in Pretoria; a rugby academy in KwaZulu-
Natal; and the University in Pretoria.
Psychological wellbeing was measured by using the State-Trait Personality Inventory
(Form Y) (STPI-Y), which provides information about state anxiety, trait anxiety, state
curiosity, trait curiosity, state anger, trait anger, state depression, and trait depression.
The presence, or absence, of these constructs was considered and evaluated to
provide an indication of psychological wellbeing. Physiological wellbeing was measured
by the Viport, a novel device that provides insight into the current stress load on the
heart via the cardiac stress index. Blood pressure was also utilised as a measure for
physiological wellbeing. These results were statistically analysed to determine the relationships between anger, aggression and psychophysiological wellbeing, and to
differentiate between the results obtained from the groups.
The investigation revealed multiple and significant relationships, both positive and
negative, between anger,aggression and psychophysiological wellbeing for both the
kickboxing and rugby groups. Almost all measures of psychological wellbeing revealed
significant relationships for the group not participating in kickboxing or rugby; however,
no significant relationships were found for measures of physiological wellbeing. For the
kickboxing group, a positive relationship was found between anger, aggression, and
heart rate. The rugby group obtained an inverse relationship between anger,
aggression, and heart rate variability. A relatively strong positive relationship between
anger, aggression, and trait anxiety exists in all three groups, with an overall negative
relationship between anger, aggression, and curiosity. The three groups were
compared to identify differences regarding psychological and physiological
wellbeing. Significant differences were observed between the three groups regarding
some forms of psychological and physiological wellbeing.The results indicated that the
pro-social physical expression of anger and aggression does have an effect on
psychophysiological wellbeing, but that these effects do vary. Further research on the
topic is recommended to gain a better understanding of the exact effects that
expressing anger and aggression in a pro-social physical manner have on
psychophysiological wellbeing.
