Research paper thumbnail of EFFECTS OF INTERACTION BETWEEN PHYSICAL AND MENTAL WORKLOAD ON HUMAN PERFORMANCE

This research study investigates the interaction of physical workload, mental workload and arousal level on performance and working memory. Fifteen participants (ages 25-35) performed a physical task (pedalling on a bicycle-ergometer) under three different levels of resistance load (low, mid and high) concurrently with a mental task (arithmetic) at three levels of demand (simple, intermediate and difficult). Participants also completed two subjective assessments following the task, Borg-CR10 and NASA-TLX to evaluate the perceived physical and mental workload respectively. The hypothesis of the study is that optimum performance occurs at intermediate levels of workload, whereas poor performance is observed at the low and high levels of physical and mental demand due to underload and overload.

The experimental hypotheses predict that performance will decrease under conditions of both high level of physical demand (i.e. cycling at 80% of VO2 max) and the complex mental arithmetic task, due to overload and high arousal levels. In addition, performance deteriorations will also occur under conditions of low physical workload (i.e. cycling at 20% of VO2 max) and low mental task demands (simple arithmetic task) due to underload and low arousal levels. Conversely, acceptable performance on the arithmetic task is expected at the intermediate level of physical and mental workload. Moreover, the study also seeks to determine if high/low combinations of physical and mental workload interact, such that (for instance) higher levels of physical workload can compensate for decrements in performance due to mental underload. The current experiment was designed to investigate the interaction effects of physical workload (PWL) and mental workload (MWL) under different conditions and arousal levels on working memory performance tasks as illustrated in Table 1. Participants were asked to conduct a mental arithmetic task concurrently with a physical task, with the dependent variable being performance on the arithmetic task. The study also sought to examine whether an interaction with high levels of physical workload can compensate for the performance shrinkage caused by mental underload.
