<\/a><\/p>\nMatthew Stork, a doctoral candidate in University of British Columbia, has been studying\u00a0the impact of music on\u00a0HIIT. His previous finding on this topic is that self-selected music has a positive impact on the peak and mean power output(Stork, Kwan, Gibala, & Martin Ginis, 2015). The new study added more psychological and emotional factors to the findings(Stork & Martin Ginis, 2016).\u00a0The study showed that the exercise attitudes was significantly better in the music group but the intention score did not change, which left the meaningfulness of the study questionable. The question needs to be answered\u00a0is whether\u00a0those questionnaire scores utilized in the study were valid. The scale for attitudes had a Cronbach\u2019s alpha of 0.72, which is low for an instrument,\u00a0for\u00a0an instrument usually needs a Cronbach\u2019s alpha of over\u00a00.9 to be justified as a reliable instrument. Even if we assume the questionnaires were valid\u00a0, what a better attitude towards HIIT means is still not clear. Is it enough to convince people\u00a0that the results of HIIT is worth the pain? Or this study only tells us those who love HIIT will love HIIT with or without their music,\u00a0and those who don\u2019t will never do even adding some music can make you feel slight better if you try.<\/p>\n
Another problem with this study was its sample size.\u00a0Only 20 people aging 18 to 30 who usually had moderate-level exercise and had not been exposed to intense interval training were included in the study, which make its generalizability very limited\u00a0. Some fitness enthusiasts may think of music as a distraction and do not like music when they exercise. Thus this study only revealed the possibility that\u00a0music may be used as a sort of comfort or stimulant, but whether it helps motivating people to choose a higher intensity remains unclear.<\/p>\n
