Abstract
The high prevalence of obesity and physical inactivity within the U.S. has become a public health crisis. PURPOSE: To examine the effects of High-Intensity Functional Training (HIFT) on the perceptions and beliefs towards exercise in an inactive sample of females. METHODS: Inactive, middle-aged females (n=8) were recruited to participate in an 8-week supervised and verified intervention (2-weeks High-Intensity Interval Training (On-Ramp), followed by 6-weeks of HIFT) three days per week. Pre- and post-assessments included: body composition (percent body fat (%BF)), strength (1RM bench press (BP), 5RM deadlift (DL)), a stage-graded exercise treadmill test ( O2max), and a Health Belief Model Scale for Exercise (HMBS-E). The HBMS-E was distributed weekly to assess changes in perceptions and beliefs towards exercise, consisting of 18 questions formatted into 5-point Likert scales. The HBMS-E questions were grouped into the five sub-categories: perceived objective barriers, perceived subjective barriers, self-efficacy, perceived severity, and cues to action. RESULTS: Participant demographics (age:39.2±7.7) and performance data are reported as pre- to post-intervention, respectively. There was a significant increase in 1RM BP (pd=2.51; 5RM DL (p=.001, d=1.83); and O2max (p=.001, d=1.81). There was a significant decrease between pre-, post- and 4-week post-intervention for objective barriers (F(2, 14)=22.238, pp=.001), and self-efficacy (F(1.075, 7.526)=9.958, p=.017). A Bonferroni post-hoc analysis was used to detect the significant differences between pre-, post-, and 4-week post-intervention. There was a significant decrease in objective barriers pre- to post-intervention and pre- to 4-week post-intervention, respectively (p=.009 and p=.002). Subjective barriers significantly decreased pre- to 4-week post-intervention (p=.011). There was a significant increase among pre-, post-, and 4-week post-intervention for self-efficacy (F(1.075, 7.526)=9.958, p=.017). There was significance pre- to post-intervention (p=.047) for self-efficacy. CONCLUSION: There is evidence to suggest HIFT has a positive influence on middle-aged females’ perceptions and beliefs of self-efficacy and barriers related to exercise.
