The Critical Power Concept And Bench Press: Modeling 1rm And Repetitions To Failure, R Hugh Morton, Matthew D. Redstone, Daniel J. Laing

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 152-160, 2014. Introduction: We demonstrate application of the 3-parameter critical power (CP) model derived for cycling and running, to performance at bench press exercise. We apply the model to both performance of a single repetition maximum (1RM) and multiple repetitions (reps) to failure at different sub-maximal weights. Methods: Sixteen weight-trained young adult male participants each performed a modified YMCA 1RM test and four sets of fixed cadence reps to failure at different sub-maximal weights. The CP model equation takes the form: n = ALC/(m – CL) + ALC/(CL – Lmax,), where n is the number ...

The Role Of High School Physical Activity Experience In College Students’ Physical Activity Motivation, Joseph S. Madonia, Anne E. Cox, Melissa L. Zahl

International Journal of Exercise Science

International Journal of Exercise Science 7(2) : 98-109, 2014. This study tested the role of past physical activity mode in predicting physical activity motivation of first year college students. Consistent with self-determination theory, perceived competence and autonomy were expected to mediate the relationships of specific types of physical activity engaged in during high school to autonomous motivation for physical activity in college. College students (N = 124; Mage= 18.42, SD = 0.51) completed an online questionnaire that assessed frequency of engagement in different modes of physical activity during their final year of high school (i.e., competitive sport, recreational ...


Environmental Correlates Of Physical Activity Among African-American Adults, Tim Bungum, Jennifer Pharr, Paulo S. Pinheiro, Maria Azzarelli 2014 University of Nevada, Las Vegas

Environmental Correlates Of Physical Activity Among African-American Adults, Tim Bungum, Jennifer Pharr, Paulo S. Pinheiro, Maria Azzarelli

Nevada Journal of Public Health

The purpose of this cross-sectional study was to identify perceived environmental correlates of meeting physical activity guidelines among African-American adults living in Southern Nevada. Trained interviewers phoned potential participants who lived in the 12 zip codes of Clark County, Nevada with the highest proportions of African-American residents. Respondents (n=237) answered 52 health-related and demographic questions. Slightly less than 50% of participants met physical activity guidelines. A factor analysis procedure produced two environmental variables, neighborhood safety and environmental supports for physical activity. Age, gender and educational attainment (p<.05) predicted the meeting of those guidelines (R2=.214), while neighborhood support for physical activity, neighborhood safety, and BMI failed to do so. This finding suggests that environmental factors are not strong predictors of physical activity among African- American adults, although environmental supports for physical activity approached significance. Future studies should consider assessing additional aspects of the built environment as an influence on physical activity.


Determinants Of The Magnitude Of Training Mediated Muscle Hypertrophy, Cameron Mitchell 2014 McMaster University

Determinants Of The Magnitude Of Training Mediated Muscle Hypertrophy, Cameron Mitchell

Open Access Dissertations and Theses

Chronic resistance training leads to muscle hypotrophy in a wide range of populations however most resistance training studies are relatively small in sample size

Three studies were conducted to better understand the sources of this variability. The first study employed a unilateral resistance training model to test the effects of relative training load and volume on the magnitude of hypertrophy and strength gains. This study showed that high relative training loads were no better than low training loads at inducing muscle hypertrophy provided that each set was performed to the point of muscular exhaustion. In agreement with previous finding, strength ...


Nutritional And Contractile Regulation Of Human Muscle Protein Synthesis: Role Of Leucine And Citrulline, Tyler A. Churchward-Venne 2014 McMaster University

Nutritional And Contractile Regulation Of Human Muscle Protein Synthesis: Role Of Leucine And Citrulline, Tyler A. Churchward-Venne

Open Access Dissertations and Theses

Amino acids are key nutritional stimuli that are both substrate for muscle protein synthesis (MPS), and signaling molecules that regulate the translational machinery. There is a dose-dependent relationship between protein intake and MPS that differs between young and elderly subjects. The current thesis contains results from three separate studies that were conducted to examine to potential to enhance smaller doses of protein, known to be suboptimal in their capacity to stimulate MPS, through supplementation with specific amino acids, namely leucine and citrulline.

The first two studies examined the potential to enhance the muscle protein synthetic capacity of a smaller, suboptimal ...

The Sensorimotor Control Of Human Standing Posture: An Investigation Into The Relationship Among Attention, Visual Feedback And Age, Ting Ting Yeh

Open Access Dissertations and Theses

Maintaining upright posture is seemingly an automatic task in younger adults, but it may require additional resources in late adulthood due to decreases in sensorimotor and cognitive functions. The thesis used a dual-task paradigm to investigate age-related changes in relation to the secondary task and context-dependent factors attributes to postural control. The postural task involved visuomotor tracking. Successfully performing the visuomotor task necessitated proper sensory feedback, motor response, and sensorimotor integration. Moreover, we used silent counting as a cognitive task to investigate attentional demands on postural control and age-related difference in cognitive processing.

We first investigated the relative contributions of ...
