About

Anxiety levels among the younger generation especially students have been increasing drastically in recent years. This severely affects a student's academics as previous studies have shown a strong correlation between high anxiety levels and poor working memory. Working memory, also known as short term memory is an important component in studying as it aids in holding important information needed to understand following information for a short period of time. This concerning phenomenon has drawn the attention of researchers to find solutions to this issue where recent studies have found physical exercise to contribute in the improvement of cognition which also includes working memory. Hence, the aim of this study is to compare the effects of low and high intensity exercises on working memory among students with high anxiety levels. Thirty female undergraduate students from UTAR with relatively high levels of anxiety will be conveniently sampled using Beck Anxiety Inventory. Participants will then be randomly allocated into 2 groups to undergo low and high intensity exercise on a treadmill according to Balke's Protocol. 2 memory assessments involving Verbal Memory Task will be conducted for each participant before and after the intervention.

30 participants in 2 patient groups

high intensity exercise

Active Comparator group

Description:

high intensity exercise on a treadmill according to Balke's Protocol. high intensity of exercises for each group of 15 participants were set at 80-85% VO2 max (Schneider, S., et al., 2009). To determine the targeted HR for low and high intensity aerobic exercise for each participant, the needed VO2 max percentages were subbed into the Swain equation as follows: %VO2 max = (%HRmax - 37)/0.64 Exercise HR/HRmax = %HRmax After rearrangement, it will be: %HRmax = %VO2 max x 0.64 + 37 Exercise HR = %HRmax x HRmax During the experimental session, each participant performed physical exercise training on the treadmill according to Balke's Protocol. The reliability of this protocol was tested by Leddy, et. al. (2011).

Other: Exercise

low intensity exercise

Active Comparator group

Description:

low intensity exercise on a treadmill according to Balke's Protocol. low intensity of exercises for each group of 15 participants were set at 50-55% VO2 max (Schneider, S., et al., 2009). To determine the targeted HR for low and high intensity aerobic exercise for each participant, the needed VO2 max percentages were subbed into the Swain equation as follows: %VO2 max = (%HRmax - 37)/0.64 Exercise HR/HRmax = %HRmax After rearrangement, it will be: %HRmax = %VO2 max x 0.64 + 37 Exercise HR = %HRmax x HRmax During the experimental session, each participant performed physical exercise training on the treadmill according to Balke's Protocol.
