Abstract:
Objective:To explore the relationship between the adiposity index and the maximum fat oxidation intensity (Fat max ) of obese female college students, and to provide a composite indicas for formulating exercise prescriptions.
Methods:Fifty four obese female college students without sports background in Chongqing from June 2017 to March 2018 were selected as subjects. Fat max was measured through an incremental load exercise test on a sports treadmill in all participants. Differences of fat max among pariticipants with different body fat percentage(BFP), waist to hip ratio(WHR), and skinfold thickness of different parts (abdomen, lower scapula, upper arm and humerus) were compared. Associations between different body fat percentage(BFP), waist to hip ratio(WHR), skinfold thickness of different parts (abdomen, lower scapula, upper arm triceps) and Fat max were analyzed.
Results:Fat max (MET, %VO 2max ) of female college students classified as obese by BFP, WHR, abdominal, upper arm triceps, and lower scapula indicators were lower than the control group. Fat max [(6.19±1.21)MET, (48.71±8.62)% VO 2max ] of female college students with abdominal obesity was significantly lower than that of the control group [(7.65±0.88) MET, (57.64±8.90)% VO 2max ], all the differences were statistically significant ( t =2.48, 2.61, P <0.05). Fat max [(6.10±1.16)MET] of female college students with obesity under the scapula was significantly lower than that of the control group [(7.18±1.25)MET] ( t =2.50, P < 0.05 ), and negative correlation was found( r=-0.27, P <0.01).
Conclusion:The obesity indicas are closely related to Fat max among obese female college students, and the skinfold thickness of the abdominal and back show prominent impact on the Fat max of obese female college students.
