Kinesiology <p>Regular physical activity is recommended for the prevention of many chronic diseases and maintaining healthy body composition. Although the beneficial effects of regular exercise are well known and used to promote exercise videos, the claims made in many advertisements are often not validated. </p><p>PURPOSE: To determine the effects of two different types of high intensity interval exercise protocols in respect to heart rate (HR) during exercise and recovery, pulmonary O2 uptake (VO2), CO2 output (VCO2), caloric expenditure (CE), and substrate utilization during recovery, and psychological impacts of exercise on feelings in trained individuals. </p><p>METHODS: Healthy subjects (n=15,11 F, 4 M, 21.8 ± 0.83 yrs, ± SE) participated in this study. Subjects underwent two familiarization sessions prior to data collection where they completed either the Insanity® Plyometric Cardio Circuit (INS) or Turbo Fire® HIIT 30 (TF) exercises in a randomized order. The HR was measured at rest (30 min) ,during exercise and recovery (60 min) and expressed as % of age-predicted maximal HR (APMHR) and peak HR. Gas exchange was measured at rest and recovery. Responses of VO2, VCO2, RER were averaged at rest and five minute intervals during recovery. The caloric equivalent value for RER was used to find CE (kcal/min) at rest and corresponding five minute intervals during recovery. </p><p>RESULTS: There was no difference (P>0.05) in peak HR (TF: 176.8 bpm, INS: 179.7 bpm). There was no difference (P>0.05) in % APMHR reached (TF: 89.4%, INS: 90.9%). There was no difference in the amount of time spent at 61-70% (TF: 510s, INS: 630s) and 71-80% APMHR (TF: 575s, INS: 517s), but there was more time spent at 81-90% APMHR (TF: 576.4s, INS: 995s). Six out of 15 subjects reached >91%APMHR in TF, and nine out of 15 subjects in INS. The HR was higher (P<0.05) after INS (55min). The recovery HR was higher (P<0.05) than resting HR after TF and INS (60min). Values of VO2 were higher (P<0.05) after INS (25, 45min). Recovery VO2 was higher (P<0.05) than resting after INS (20 min) and TF (10 min). There were no differences (P>0.05) in VCO2 between TF and INS. Recovery VCO2 was higher (P<0.05) than resting after INS (10,40, 50-60 min) and TF (10, 40-55min). The RER was lower (P<0.05) after INS (20, 35 min). Recovery RER was lower (P<0.05) than resting after INS (10-60 min) and TF (5, 15-60 min). Values of CE was higher (P<0.05) after INS (5 min). Recovery CE was higher (P<0.05) than resting after INS (20 min) and TF (10 min). Tranquility was lower (P<0.05) after INS and TF. Physical Exhaustion was higher (P<0.05) after INS and TF, but higher (P<0.05) after INS than after TF. There were no differences (P>0.05) in Positive Engagement and Revitalization. </p><p>CONCLUSIONS: Results of the HR response during exercise indicates that Insanity® was a higher intensity workout and led to a higher recovery HR. Fat was used as a primary fuel source for the majority of recovery for Insanity® and Turbo Fire®, but more reliance was on fat after Insanity®. The CE was elevated longer after Insanity®, but was back to resting for the majority of recovery. Insanity® led to a higher level of Physical Exhaustion, but neither protocol changed the decrease in Tranquility.</p> 2012-07-17 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1333716469 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1333716469 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
