Concurrent Strength Training on Biomechanical andPhysiological Markers: Implications for Management of Adolescent Obesity (PhD Proposal) Jeffrey C. Pagaduan, Msc(cand), CSCS
Summary• Introduction• Hypotheses• Methodology of Studies• Time Frame
IntroductionCentral obesity is defined as the accumulation ofexcessive fat in the abdominal region.For South East Asians, the waist circumference cut-offfor central obesity is > 90 cm for males and >80 cm forfemales (IDF, 2006) Adolescent obesity is associated with severe obesity in adulthood (The et al., 2011)
Figure 1. Physiological Effects of Obesity Vasan, 2003
Obesity cause alterations in heart rate variabilityparameters (Kim et al., 2005)Pulse wave velocity, a measure of arterial functioning,is decreased with obesity (Fojas, 2005)
Obese children have lower vertical jump and standinglong jump compared to their non-obese counterparts(Riddoford-Harland, Steel and Baur, 2006)Obese adolescents have stronger isometric strength butshowed lower upper body, trunk and lower body strengththan non-obese (Fogelholm, 2006)
In the recent decade, concurrent training is utlized asan intervention to treat obesity (Rose et al., 2010;Lambers et al., 2008)Concurrent training is the combination of endurancetraining and resistance training in one single session
To the researchers knowledge, there has been no study onadolescent obesity using concurrent training.Understanding physiological and biomechanical adaptationsto various stimuli in concurrent training may providerelevant information to the potential of concurrent trainingin the management of adolescent obesity.
HypothesesStudy 1:a. There will be significant differences on thebiomechanical and physiological markers betweenobese and non-obese.b. Discriminating factors in physiological andbiomechanical factor exist between obese and non-obese
Study 2:a. Significant differences will exist in biomechanical andphysiological markers of between to concurrent traininginterventions on adolescent obesityStudy 3:a. Significant differences will exist in the biomechanicaland physiological markers of concurrent trainingschemes following different periodization models.
