6. CONCLUSION
6.1 RECOMMENDATIONS
Future investigations looking into fatigue during exercise and the time course changes in fatigue indicators such as RPE, workload, and HR response should consider the following recommendations:
1. Future studies should consider using the constant HR condition but this must be performed at higher HR ranges to see where participants struggled to maintain their workload constant - such as in the current study. For example, future studies can look at the current constant HR set-up and have participants exercising at 60%, 70%, and 80% of their maximal heart rate. If HR is increased, there must be a point where performance decrements will occur. However, the current study did not establish such a situation.
2. The constant RPE condition needs to be assessed where the participants actually exercise at a constant RPE in order to establish whether they can manage this condition; and if so, which RPE range can participants manage to maintain. In addition, it must be assessed at which range are participants not able to maintain a constant RPE.
3. Assess different workload ranges which are higher than those used in the current research project so it can be established which percentage of each participant’s exercise activity leads to exercise fatigue and exercise termination as this was not achieved in the current study.
4. Future investigation within the scope of the current research project should consider investigating the reproducibility of the current study’s findings under different exercise types (such as resistance-training exercise, intermittent- training exercise etc.). In addition, the current research project can be repeated with participants of varying training statuses.
5. Future research should consider the participants’ energy intake by adding conditions to the current research’s methodological scope where condition one will be controlled energy-intake to improve endurance performance;
group two will control energy-intake to hamper endurance performance, and group three will be the placebo group. This would facilitate the understanding
6. Lastly, investigation under the current research methodological scope should consider the use of professional athletes from various sporting codes. This would allow for the investigation of whether there is a universal precursor fatigue-indicator for various sporting codes, or do different sporting codes have different fatigue-indicators.
