Hamstring injuries are one of the most common injuries sustained in professional football with 800+ hamstring injuries per year. These hamstring injuries often occur between late swing (eccentric contraction) and early ground contact. PURPOSE: To investigate the correlation of eccentric hamstring strength to muscle volume across positional groups. METHODS: Athletes were divided into three homogeneous groups based on position (big (e.g., linemen), skill (e.g., receivers), combo (e.g., linebackers)). Seventy-three NCAA Division I football players participated (24 big, 37 skill, and 12 combo). Hamstring strength was collected for each leg while performing 3 Nordic curls on a Nordbord device. The peak …

Background: The purpose of this study was to investigate the effects of 9 weeks’ resistance training utilizing a daily undulating periodization (DUP) program versus a linear periodization (LP) program on concentric and isometric muscle strength and neuromuscular function of the quadriceps muscle. Material and methods: 30 male subjects (age = 21.7 ±2.5 yr, body mass = 71.4 ±11.9 kg, height =1.77 ±0.09 m) participated in the study. Subjects were randomly divided into DUP and LP training groups. Both the DUP and LP training group performed leg press exercise 3 times per week. Volume and intensity were equated for each training …

Background: Obesity affects health parameters that are related to physical activity. The present study examined the relationship between weight and three such parameters in young boys and girls, bone properties, muscle strength, and motor coordination. Material and methods: The study consisted of second- and third-grade 286 students – 144 boys and 142 girls participants. Bone properties were measured at the distal radius and tibia shaft by Speed of Sound technology. Tests were conducted to measure muscle strength and motor coordination. Results: Obese boys were characterized by lower bone properties (p < .01) in the tibia bone than normal-weight boys. They were significantly (p < .05) weaker than normal-weight boys on muscle strength tests. Obese boys scored significantly (p < .05) lower on coordination tests than the normal weight boys. Underweight girls maintained higher bone properties than did the girls in all other BMI categories. Normal-weight girls scored significantly (p < .05) higher than obese girls on muscle strength tests. Obese girls scored significantly (p < .05) lower than normal-weight girls on motor coordination tests. Conclusions: The findings emphasize the need to identify obese children and refer them to special weight loss and exercise programs.

Background: The aim of this study was to compare the lower limb muscle strength in terms of gender and limb dominancy in prepubescent swimmers. Material and methods: Seventy-four prepubescent swimmers (mean age: 11.01±1.58 years; 42 boys; 32 girls) who were training for at least 8 hours a week and without current lower limb pain participated in the study. Isometric muscle strength of lower limb was measured by hand-held dynamometry. Independent samples-t test was used to determine the difference between genders, while paired samples-t test was used for dominant-nondominant side comparison. The significance level was accepted as p<0.05. Results: Knee flexion (p<0.001), extension (p<0.001) and ankle dorsiflexion (p=0.003) muscle strength were stronger on the dominant side than on the non-dominant side. Knee flexion/extension strength ratio was similar (p=0.957); while ankle plantar flexion/dorsiflexion strength ratio was significantly different (p=0.011). Boys swimmers had stronger isometric muscle strength in the dominant side together with knee flexion (p=0.018) and knee flexion extension strength ratio (p=0.007) than girls swimmers. Conclusions: Boys swimmers had higher dominant side knee flexion muscle strength compared to female peers. Gender and lower limb dominancy might be important for lower limb muscle strength to show varieties in prepubescent swimmers before planning a training program.

Peak Isokinetic Torque Of Knee Flexors And Extensor Muscles Of College Football Players, David L. Boerem
Peak Isokinetic Torque Of Knee Flexors And Extensor Muscles Of College Football Players, David L. Boerem
University of the Pacific Theses and Dissertations
The problem of the study addressed knee injuries in college football. Imbalance of the musculature surrounding the knee would predispose the athlete to knee injury. Recognition of those who have muscular deficiencies would be a primary way of preventing knee injuries. The focus of the study was to determine if there was a significant difference in peak isokinetic torque of knee flexor and extensor muscles across speeds (60 degrees/second, 180 degrees/ second and 300 degrees/second) of a college football team subsequent to participation in a spring football season.
