Physical Education KS4 / GCSE: High Intensity Impact Training
High Intensity Interval Training (HIIT) is compared to other forms of exercise.
Four Groups of 24 adult volunteers between the ages of 40-60 were selected to try out different forms of exercise.
HIIT involves alternating short bursts of intense exercise with brief recovery periods.
Two groups follow three sessions a week for 15 minutes using HIIT methods: one group perform on laboratory style exercise bikes; and another perform specifically designed exercises to be completed at home that require no equipment.
A third group follow government guidelines of moderate exercise for 150 minutes per week, and a fourth group participate in ‘Grip Strength Dynamometry’ or ‘Hand Grip Training’ for 8 minutes, three times a week.
The four groups are all VO2 Max tested and measured before and after the period of training.
VO2 max testing refers to the maximum amount of oxygen that an individual can utilise during maximal exercise.
This measurement is generally considered the best indicator of cardiovascular fitness and aerobic endurance.
Blood pressure is also measured for all groups before and after.
Significant differences were observed for the different groups.
Presented by Dr Chris and introduced by British athlete Dina Asher-Smith.
Teachers can use the investigation as a springboard to discuss the short and longer-term effects of exercise on the body, including how the cardiovascular, respiratory, energy and muscular systems all work together to supply energy and remove waste products.
The function of these systems also improves their efficiency and the VO2 max scores can be discussed in this regard.
Principles of training (SPORT and FITT) can be also be applied in relation to the types of training introduced in the clip.
Teachers should task pupils to use the information from the clip and further ‘research’ to examine and then explain the different VO2 Max and blood pressure results from the different training approaches.
This clip is suitable for teaching Physical Education at KS4 in England, Wales and Northern Ireland and National 4 and 5 in Scotland.
