Subjects
Forty-eight subjects who had mild to moderate asthma, 28 boys and 20 girls aged 12 to 17 years, participated in this study after they and their parents gave informed consent. All the subjects had been acclimatized to moderate altitude (1,300 m) for four months prior to testing. Their anthropometric characteristics and spirometric values are listed in Tables 1 and 2. All were relatively inactive; though not released from physical education at school, leisure physical activity was limited. None
RESULTS
Table 3 presents the values of max and maximum HR obtained by both direct measurement and the 20-MST for the entire population. The values of maximum HR were significantly higher for the 20-MST (t = 5.25, p<0.01). However, no significant differences were noted in the max values (t = 1.10, p = 0.30). A significant correlation (r = 0.84, p<0.01) was obtained between the two tests for max assessment (Fig 1). The standard error of the estimate presents a lower value (S
DISCUSSION
This study shows that the 20-MST is valid for the determination of max and for the assessment of cardiorespiratory adaptations over the course of an individualized aerobic training program for mild to moderately asthmatic children acclimatized to moderate altitude.

Effect of high-intensity interval training in adolescents with asthma: The eXercise for Asthma with Commando Joe's® (X4ACJ) trial
2021, Journal of Sport and Health ScienceCitation Excerpt :This greater increase may be related to the (non-significantly) lower baseline fitness in those with asthma since baseline fitness has been reported to influence the magnitude of change elicited by an intervention in youth.60–62 Although improvements in peak VO2 after moderate-intensity exercise over a shorter time-frame16,17,63,64 have been noted in those with asthma, the suitability of continuous exercise for those with asthma is questionable. Indeed, research has suggested that prolonged continuous exercise is not enjoyable26 and may trigger the onset of asthma symptoms,29 both of which are key barriers to exercise for those with asthma.14
