Physical education (PE) subject is an important component in the national curriculum in Malaysia to produce a healthy and fit young generation. Active involvement in physical activity and exercise can improve cognitive function and aerobic capacity of children. In regards to that, High Intensity Interval Training (HIIT) is an alternative training protocol to improve body physiological function, fitness performance and health. Furthermore, HIIT has recently attracted significant research attention in a wide range of population lately. The objective of this study is to investigate the need of High Intensity Interval Training (HIIT) in the implementation of PE activities. The survey study through a questionnaire involved a total of 220 primary school PE teachers who were selected by purposive sampling technique. The questionnaire was divided into two parts, part A consists of information and background of the respondents, part B is about the development of HIIT activity module implementation in PE. Data were analyzed descriptively. This study showed that 86.8 percent of teachers agree that there is a need to develop HIIT module for PE subject as an initiation of HIIT activities in PE to ensure the practice of HIIT activities in long term among young minds. The implications of this study suggested that teachers pay attention to the need to develop HIIT module as an alternative training program that increases physical fitness among kids. Therefore, this study is expected to provide a basic overview of the need to develop a HIIT module to be practiced in PE class as the implementation of HIIT improves aerobic fitness optimally in a shorter time period.

Executive function, attention, and memory are an important indicator of cognitive health of children. Cardiovascular fitness has a positive relationship with cognitive function performance. IFITTKIDS module is a training programme guided by High Intensity Interval Training (HIIT) used to see the effect on memory strength, attention and aerobic capacity.This HIIT training is able to increase the fitness level optimally in a short period of time. This study was conducted quantitatively using a 'Pre and post control group design'. The study subjects consisted of 64 primary school students aged 11 years who were divided into two groups namely 32 participants in the treatment group and 32 in the control group. The intervention was conducted for 12 weeks with a training frequency of two times a week for 20 minutes per session. The results using ANCOVA test analysis showed that by adjusting the pre-test score as a covariate, the post-test score for memory strength, attention and aerobic capacity of the treatment group was significantly higher with the score from the control group with F (1.61) = 68.15, p <.05, and eta squared = .53, F(1,61) = 54.906, p < .05, eta squared = .47 and F (1.61) = 63,987, p <.05, and eta squared = .51. Substantially, the findings of this study show that HIIT training guided by IFITTKIDS MODULE for 8 weeks is productive in improvising aerobic capacity and memory strength in 11-year-old school children. The results of this study, recommend that this IFITTKIDS MODULE can be used as one of the training programme to increase the level of memory strength, attention and aerobic capacity in children.
