“…As expected, our results for the ET group corroborate data from the literature, demonstrating mild but statistically significant changes in the main anthropometric and plasma markers of cardiac risk, in addition to the functional capacity as assessed by the aerobic capacity measured with AnT in relation to the controls [24][25][26][27] .…”

“…[15][16][17][18][19] The impact of exercise intensity on change in body composition is equivocal. [20][21][22][23] Our results suggest that change in overall activity, but not change in any of the subcomponents of activity, is inversely associated with change in FM. This would then suggest that an increase in overall PA, regardless of the exercise intensity, might be an effective strategy to prevent FM gain.…”

“…[15][16][17][18][19] One recent study has suggested a prospective association between PA and change in FM but this association was modified by age. 20 Furthermore, the potential impact of exercise intensity on change in BW and FM remains elusive, [21][22][23][24] and it is not known which if any of the subcomponents of free-living PA contributes more to change in BW and FM.…”

Does physical activity equally predict gain in fat mass among obese and nonobese young adults?

Background: Differences in energy metabolism and physical activity (PA) may contribute to the long-term regulation of body weight (BW). Objective: To examine the associations between metabolic determinants, energy expenditure and objectively measured components of PA with change in BW and fat mass (FM). Design: Prospective (4 years.), case-control study in obese (n ¼ 13) and normal weight (n ¼ 15) young adults. Measurements: At baseline, we measured resting metabolic rate, substrate oxidation, movement economy (ml O 2 kg À1 min À1 ), aerobic fitness (VO 2max ), total and PA energy expenditure by doubly labelled water, and PA by accelerometry. Fat mass was measured by DXA. At follow-up we repeated our measurements of PA and FM. Results: Fat mass increased significantly (Po0.001) in both groups. Physical activity did not change between baseline and 'follow up'. Change in overall PA (counts per minute) was inversely associated with change in BW and (b ¼ À0.0124, P ¼ 0.054) and FM (b ¼ À0.008, P ¼ 0.04). Post hoc analyses suggested that this association was explained by changes in the normal weight group only (b ¼ À0.01; P ¼ 0.008; and b ¼ À0.0097; P ¼ 0.009, for BW and FM, respectively). Metabolic determinants, energy expenditure estimates and subcomponents of PA (i.e. time spent at different intensity levels) were not significantly associated with change in BW or FM. Conclusion: Our results suggest an independent association between PA and FM. However, this association may differ depending on obesity status. The gain in FM, without any change in PA, may suggest that dietary intake is the major contributor to the positive energy balance.

“…20 With regard to SSE, the FM and aerobic fitness response was typical of that reported in the literature in that there were no significant changes in TBM, FM or trunk fat, but there was a significant increase in aerobic fitness. [26][27][28][29][30][31][32] Central adiposity diminished in the HIIE compared to the SSE and CONT groups. The HIIE group decreased central abdominal fat by 9.5%, in contrast to the SSE group, which had a 10.5% increase.…”

The effects of high-intensity intermittent exercise training on fat loss and fasting insulin levels of young women

et al. 2008

Objective: To determine the effects of a 15-week high-intensity intermittent exercise (HIIE) program on subcutaneous and trunk fat and insulin resistance of young women. Design and procedures: Subjects were randomly assigned to one of the three groups: HIIE (n ¼ 15), steady-state exercise (SSE; n ¼ 15) or control (CONT; n ¼ 15). HIIE and SSE groups underwent a 15-week exercise intervention. Subjects: Forty-five women with a mean BMI of 23.2 ± 2.0 kg m À2 and age of 20.2 ± 2.0 years. Results: Both exercise groups demonstrated a significant improvement (Po0.05) in cardiovascular fitness. However, only the HIIE group had a significant reduction in total body mass (TBM), fat mass (FM), trunk fat and fasting plasma insulin levels. There was significant fat loss (Po0.05) in legs compared to arms in the HIIE group only. Lean compared to overweight women lost less fat after HIIE. Decreases in leptin concentrations were negatively correlated with increases in VO 2peak (r ¼ À0.57, Po0.05) and positively correlated with decreases in TBM (r ¼ 0.47; Po0.0001). There was no significant change in adiponectin levels after training. Conclusions: HIIE three times per week for 15 weeks compared to the same frequency of SSE exercise was associated with significant reductions in total body fat, subcutaneous leg and trunk fat, and insulin resistance in young women.
