Introduction – 20 marks
The introduction begins by highlighting the significance of both aerobic and anaerobic power in the performance of mountain biking races. Both aerobic and anaerobic power play a huge role in cross-country mountain banking due to the high-intensity energy involved. The significance of both aerobic and anaerobic power is evident from the strong relationship between peak power output and the high intensity performance during cross-country mountain biking, the maximum uptake of oxygen, lactate and ventilator thresholds, and the ability to achieve repeated anaerobic efforts.
The introduction also describes the suggestion that bikers with maximum uptake of oxygen should utilize mountain biking to promote their capacities to engage in high intensity maximum aerobic and anaerobic power workouts. Mountain bikers should generate supramaximal effort when undertaking specific phases during competition (Inoue et al., 2016). This implies that mountain bike training should incorporate programs that require submaximal effort at the beginning of blood lactate accumulation, maximum uptake of oxygen intensities, supramiximal intensities, as well as peak power output to enhance performance.
2b
The study objective is given in the introduction by showing the gaps from previous studies that failed to provide a direct comparison between high intensity aerobic training and sprint interval training. Previous studies evaluated them individually and no study has examined their effects to mountain bikers. This comparison is important for beginning the research because it will help mountain athletes and coaches to determine the best mode of training for optimizing mountain biking performance.
Methods – 20 marks
Item 3
The methods section acknowledges that all the study took place after explaining all the experimental procedures to the participants of the study and receiving a written consent from each one of them. The study received an approval from the Institutional Ethics Committee of Gama Filho University and the procedures followed the Helsinki declaration. The study was incorporated into the clinical trial registration database of the U.S. National Institutes of Health and both the Consort checklist and protocols used as trial are given as supporting information.
Item 4a and 4b
Yes, all the participants were aged 18 years and above and had adequate training and mountain biking experience. They volunteered to participate in the study and The participants were randomly assigned into the high intensity or the sprint intensity groups. They trained consistently for six days and competed regularly for five years used to conduct the study. Their peak power output and maximal oxygen uptake values helped to come up with three cohort levels.
Item 5
The statistical analysis utilized descriptive statistics to provide the mean as well as the standard deviation. The results of the race simulation results were analyzed using ANOVA with pre and post training time and the training modality remaining constant variables.

Item 9
This study shows that experienced mountain bikers exhibit enhanced performance in MTB race simulation and improved physiological variables after participating in training programs incorporating either high intensity or sprint intensity programs.
Item 10
ACOVA results disputed the hypothesis by showing that high intensity training is superior to sprint intensity in terms of enhancing mountain bike racing performance as seen in the simulation.
Item 11
The absence of studies about the different training for mountain biking hindered the comparison for high intensity and sprint intensity activities but the simulations agreed with previous studies on road cyclists. This implies that the results of this study agreed with previous studies investigating the significance of various training modalities for road cycling performance. Improvements in mountain biking performance after both high intensity training and sprint intensity training suggest a connection between the use of high percentage of the maximal aerobic power and sustaining prolonged high-energy physical work.
Item 12
The results of the study reveal that the 6 weeks mountain bike training for either high intensity or sprint intensity activities are effective at enhancing mountain biking performance and additional physiological variables.
Item 13
The magnitude-base inference approach showed that the high intensity modality provides more benefits towards improving mountain biking performance with very low probability of causing any harm to the biker.
