Relationships Between Anthropometry And Maximal Strength In Male Classic Powerlifters, Pierre-Marc Ferland, Antoine Laurier, Alain-Steve Comtois

International Journal of Exercise Science

International Journal of Exercise Science 13(4): 1512-1531, 2020. Several studies have determined the influence of physical characteristics on strength. The present quantified the relationships between anthropometry and maximal strength. Male classic powerlifters (n=59) were measured before a championship. Two-tailed Pearson correlation analysis was used. Powerlifters that presented higher relative maximal strength (RMS) in the squat and bench generally had higher body weight (BW), body mass index (BMI), torso circumference (C), waist C/height, torso C/height (r=0.26 to 0.49, p<0.05), and smaller lower leg length (L)/height and forearm L/torso C (r=-0.31 to -0.45, p<0.05) ratios. Powerlifters with a higher % of their deadlift on their total generally presented a smaller BW, BMI, body fat percentage (BF%), waist and torso C, trunk L, waist C/height, torso C/height, trunk L/height, waist C/hip C, thigh L/ lower leg L, trunk L/thigh L ratios (r=-0.26 to -0.49, p<0.05) and higher lower leg L, lower leg L/height, reach/height, and forearm L/torso C ratios (r=0.32 to 0.51, p<0.05). Stepwise regressions revealed that a bigger torso positively predicted absolute maximal strength (AMS) in the squat (β=0.41, p=0.04), the bench (β=0.77, p<0.01), the deadlift (β=0.88, p<0.01) and the total (β=0.89, p<0.01), that a higher torso C/height ratio positively predicted RMS in the squat(β=0.48, p<0.01), the bench (β=-0.87, p<0.01) and the total (β=0.66, p<0.01), and that reach/height positively predicted RMS in the deadlift (β=0.37, p<0.01) and it’s % on the total (β=0.31, p<0.01), but negatively predicted RMS in the bench (β=-0.25, p=0.02) and its % on the total (β=-0.24, p=0.04) As all of the stronger correlations came from AMS, powerlifters should focus on increasing AMS (weight lifted) instead of RMS (Wilks pts).

Senior Honors Theses

As medical professionals, athletic trainers are focused on the overall well-being of their patients. When an injury occurs, the entire extent of the impact the injury has on a patient’s life and daily activities needs to be taken into consideration. Like other medical professionals, we have adopted the use of the World Health Organization’s ICF model. This disablement model is used to organize clinical decisions in order to best provide evidence-based care. It provides a framework for documenting a patient’s ability to function and the disability. One major key of the ICF model is the use of ...

Winning In Weight-Loss: The Interaction Of Conscientiousness And Perceived Autonomy, Jason M. Curtis, Marc Lochbaum

NeuroSports

ABSTRACT

Background

Understanding determinants for weight-loss is a national priority. Obesity is an epidemic with serious health consequences. Most of today’s obesity and overweight problems are being attributed to poor diets and not enough physical activity. These problems show no signs of slowing down with the behaviors of most Americans. The phenomenon of “The Biggest Loser” (different variants of weight-loss programs that consist of group exercise participation and nutrition therapy to elicit weight-loss, and hopefully behavior change) has spawned many variants in commercial health clubs. This prospectus study examined the direct and interactive or moderated effects of known determinants ...
