Evaluation of the strength of selected muscle groups and the range of motion in sport aerobics athletes
Sílová, Markéta ; Žáková, Lenka (advisor) ; Vomáčková, Helena (referee)
Title: Evaluation of the strength of selected muscle groups and the range of motion in sport aerobics athletes Objective: Sport aerobics belongs to group of sport gymnastics, which brings increased demands especially on joint mobility, muscle strength and coordination of movement. Athletes are selected according to these prerequisites the development of which is still supported by training. The thesis follow up the physical measurement of these attributes. The Aim: Evaluation of joint mobility and muscle strength of 12-16 year old sport aerobic athletes and their correlations. Furthermore, the comparison together with the level of the performance group. Method: Measurement of joint mobility using goniometry, hypermobility evaluation using Beighton score, measurement of the muscle strength using HUMAC isokinetic dynamometer. Comparison of measured results with performance group level. Results: During measurement of the joint range using the method goniometry was found, that in flexion of the hip joint had 100 % of the athletes increased joint motion. In hip extension, the joint range wasn't increased at all. Beighton score showed, that 90 % of athletes were constitutionally hypermobile. The relationship between joint range and the values of the muscle strength - peak torque has not been proven. Key...

The influence of foam rolling on range of motion, strength of the knee extensors and flexors, and H/Q ratio
Šablatúra, Michal ; Šteffl, Michal (advisor) ; Větrovský, Tomáš (referee)
Title: The influence of foam rolling on range of motion, strength of the knee extensors and flexors and H/Q ratio. Objectives: The aim of the diploma thesis was to determine the effect of the foam roller on the range of motion and strength of the extensors and flexors of the knee joint. The muscular strength of the knee extensors and flexors was determined using a Humac norm isokinetic dynamometer. Another goal was to determine the effect of the foam roller on the force ratio of extensors and flexors (H / Q) which is an important detail for the prevention of lower limb injuries Methods: This is an experimental study. The measured research group (n = 12) consisted of the students of the Faculty of Physical Education and Sport at the Charles University. A Black roll foam roller of medium hardness with a non-serrated surface was used. The range of motion of the knee flexors were measured using the sit and reach test and the knee extension test. The range of motion of the knee extensors were measured using a modified Thomas test and Ely's test. The isokinetic strength of the extensors and flexors muscles of the knee joint and the H/Q ratio were measured using a Humac Norm isokinetic dynamometer. Results: Measurements showed that the foam roller affected the range of motion of the flexors and extensors...
