Profile Of Mood States Scores Before And After An Acute Anaerobic And

Evaluate whether an acute bout of anaerobic exercise produces similar mood state responses as aerobic exercise as measured by the Profile of Mood States (POMS). The study involved 24 university students assigned to aerobic or anaerobic exercise groups. Participants completed pre- and post-exercise POMS assessments, with data analyzed using independent t-tests to compare change scores across groups. Results indicated no significant differences in mood state alterations between aerobic and anaerobic exercise groups, suggesting that both exercise modes may similarly influence mood in this context. This research contributes to understanding exercise mood responses and implications for exercise adherence and program design.

The relationship between physical activity and psychological well-being has long been a subject of interest within exercise psychology. The Profile of Mood States (POMS) is a widely utilized assessment tool designed to measure temporary mood fluctuations and has been employed in numerous studies to determine how different types of exercise influence mood (Morgan, 1980). Traditionally, research has predominantly focused on aerobic exercise's effects on mood, emphasizing its role in mood enhancement and stress mitigation. However, emerging interest surrounds whether anaerobic exercise elicits similar psychological benefits, which has practical applications for designing interventions and optimizing exercise adherence (Berger et al., 2007).

Introduction

The impact of exercise on mental health is a well-established paradigm, with numerous studies illustrating positive mood enhancements following physical activity (Weinberg & Gould, 2003). The "iceberg profile," characterized by low tension, confusion, fatigue, anger, and depression scores combined with high vigor, has been associated with optimal psychological states often observed after aerobic exercise sessions (Morgan, 1979). The primary focus has been on aerobic activity due to its accessibility and well-documented mood benefits. Nonetheless, anaerobic exercise has garnered increasing attention for its potential mood-enhancing effects, especially given its popularity in strength training and high-intensity interval training (Berger et al., 2007).

The present study investigates whether an acute bout of anaerobic exercise produces similar changes in mood as aerobic exercise by examining pre- and post-exercise POMS scores. The research hypothesis posits that aerobic exercise will result in more favorable mood scores than anaerobic exercise, aligning with prior literature suggesting greater mood benefits from aerobic activities (Weinberg & Gould, 1993). The null hypothesis states no differences in mood responses between the two exercise modalities.

Method

Participants

The study involved twenty-four university students enrolled in a kinesiology course, with participants randomly assigned to either an aerobic or anaerobic exercise group. The mean age of participants was 20.3 years (SD = 2.5), with a balanced gender distribution including 12 females and 12 males. Participants were selected based on their availability and willingness to perform both exercise modalities, with no prior experience required. The assignment was based on a university account criterion, with those having a 'two' in their account participating in anaerobic activities, and the rest in aerobic activities.

Instruments and Apparatus

The primary assessment tool was a shortened version of the Profile of Mood States (POMS; Shacham, 1983), consisting of 37 questions measuring six subscales: tension, confusion, fatigue, anger, depression, and vigor. The mood assessment was administered immediately before and after the exercise session. The exercise protocols involved various modalities: aerobic activities like treadmill walking, cycling, or elliptical, and anaerobic activities such as weightlifting and resistance training. Multiple instruments were used corresponding to participants' chosen exercises, consistent with typical gym equipment usage.

Procedures

Participants were randomly assigned into two groups—11 in the aerobic group and 13 in the anaerobic group. Upon arrival, they completed the baseline POMS questionnaire. The participants then engaged in a 20-minute exercise bout corresponding to their assigned group: aerobic participants performed continuous aerobic activity, while anaerobic participants performed resistance exercises in the gym. Following the exercise, participants completed the POMS questionnaire again to assess mood changes. All scores were collected and submitted for statistical analysis. The experiment ensured standardized instructions and exercise durations, and participants were monitored to ensure adherence to protocols.

Results

Data analysis was performed using SPSS software, focusing on the change scores calculated by subtracting pre-exercise from post-exercise POMS scores for each subscale. An independent samples t-test was conducted on the change scores to compare the mood responses between aerobic and anaerobic groups. The results indicated no statistically significant differences across any mood subscale or the Total Mood Disturbance Score (TMD), supporting the null hypothesis.

Discussion

The findings of this study support the null hypothesis, indicating that there were no significant differences in mood state changes between participants engaging in aerobic versus anaerobic exercise. Both exercise modes appeared to produce similar psychological effects in the immediate post-exercise period. This contrasts with prior research emphasizing more pronounced mood benefits associated with aerobic activity (Morgan, 1979; Weinberg & Gould, 2003), suggesting that anaerobic activities may also confer mood-enhancing benefits, potentially due to physiological mechanisms such as endorphin release or psychological factors like accomplishment and social interaction (Hoffman et al., 2012).

Several explanations could account for the absence of significant differences. Firstly, the sample size was relatively small, limiting the statistical power to detect subtle differences. Additionally, the acute nature of the intervention might have minimized familial variations in mood responses; longer-term or chronic effects might reveal differential impacts. The similar intensity and duration of exercises across groups could also contribute to comparable mood outcomes. Furthermore, individual preferences, fitness levels, and psychological predispositions may have influenced how participants responded emotionally to their workouts.

Limitations of the study include the small sample size, lack of control over participants' baseline psychological states, and variability in exercise intensity or adherence. Future research should incorporate larger samples, standardized exercise protocols, and consider moderating factors such as individual fitness levels or psychological traits. Investigating neurochemical responses, like serum endorphin levels or cortisol, in tandem with mood assessments could elucidate underlying mechanisms.

Practically, these findings suggest that exercise modality choice can be tailored to participants' interests and goals without concern for differential psychological benefits in the acute setting. Exercise professionals might emphasize participant preferences to increase adherence, given that both aerobic and anaerobic exercises appear capable of positively influencing mood. This flexibility can optimize exercise programs and support long-term psychological well-being.

Conclusion

This study contributes to the growing body of literature suggesting that both aerobic and anaerobic exercises can improve mood states in the short term. While no significant differences were observed between modalities, implications include the importance of promoting varied exercise options tailored to individual preferences, which can enhance adherence and psychological health.
