  • Good afternoon PhD Committee Panelists. I'm Jeffrey Pagaduan, an applicant for a PhD studentship. My PhD proposal is about concurrent training and adolescent obesity: its implications for biomechanical and physiological factors.
  • For the summary of my proposal. First, I'll providing a brief introduction of the concepts in the study. Then, I'll proceed to sharing some of related literature succeeded by hypotheses. After, the methodology of studies will be discussed. I will be ending by providing an estimated time frame for completing the PhD.
  • Central obesity s defined as the accumulation oxcessive fat in the abdominal region. For South East Asians, the waist circumference cut-off for central obesity is > 90 cm for males nad > 80 cm for fremales.
  • Figure 1 depicts the various physioligical responses from obesity.
  • Obesity has also been suggested to produce alterations in parasympathetic and sympathetic functioning as displayed by heart rate variability parameters. Furthermore, a decreased endothelial functioning through pulse wave velocity is also decreased with obesity.
  • Aside from changes in physiological mechanisms, obesity also produce performance dysfunction. In a study by Riddoford-Harland, Steele and Baut, they discovered that obese children have lower vertical jump and standing long jump compared to their non-obese counterparts. Similar results in terms of impaired upper body, trunk and lower body functioning were found out by Fogelholm and colleagues (2006)
  • In the recent decade, the use of physical activiity interventions has been utilized to treat obesity. One of which is concurrent training. Concurrent training combines endurance training and resistance training in one single session.
  • To the researcher's knowledge, there has been no study on adloescent obesity using various stimuli concurrent training. Understanding physiolgical and biomechanical adaptations in concurrent training may provide relevant information to this intervetnion as a potential for management of adolescent obesity.

    3. 3. 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)
    4. 4. Figure 1. Physiological Effects of Obesity Vasan, 2003
    5. 5. 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)
    6. 6. 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)
    7. 7. 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
    8. 8. 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.
    9. 9. 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
    10. 10. 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.
