1. Concurrent Strength Training on Biomechanical and
Physiological Markers: Implications for Management of
Adolescent Obesity (PhD Proposal)
Jeffrey C. Pagaduan, Msc(cand), CSCS
2. Summary
• Introduction
• Hypotheses
• Methodology of Studies
• Time Frame
3. Introduction
Central obesity is defined as the accumulation of
excessive fat in the abdominal region.
For South East Asians, the waist circumference cut-off
for central obesity is > 90 cm for males and >80 cm for
females (IDF, 2006)
Adolescent obesity is associated with severe obesity in
adulthood (The et al., 2011)
5. Obesity cause alterations in heart rate variability
parameters (Kim et al., 2005)
Pulse wave velocity, a measure of arterial functioning,
is decreased with obesity (Fojas, 2005)
6. Obese children have lower vertical jump and standing
long jump compared to their non-obese counterparts
(Riddoford-Harland, Steel and Baur, 2006)
Obese adolescents have stronger isometric strength but
showed lower upper body, trunk and lower body strength
than non-obese (Fogelholm, 2006)
7. In the recent decade, concurrent training is utlized as
an intervention to treat obesity (Rose et al., 2010;
Lambers et al., 2008)
Concurrent training is the combination of endurance
training and resistance training in one single session
8. To the researcher's knowledge, there has been no study on
adolescent obesity using concurrent training.
Understanding physiological and biomechanical adaptations
to various stimuli in concurrent training may provide
relevant information to the potential of concurrent training
in the management of adolescent obesity.
9. Hypotheses
Study 1:
a. There will be significant differences on the
biomechanical and physiological markers between
obese and non-obese.
b. Discriminating factors in physiological and
biomechanical factor exist between obese and non-
obese
10. Study 2:
a. Significant differences will exist in biomechanical and
physiological markers of between to concurrent training
interventions on adolescent obesity
Study 3:
a. Significant differences will exist in the biomechanical
and physiological markers of concurrent training
schemes following different periodization models.
13. Timeline :
Year 1: Study 1 + 2 related studies
Year 2: Study 2 + 2 related studies
Year 3: Study 3 + 2 related studies
Editor's Notes
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.
