Background: The aim of this study was to assess the histological structure (cross--sectional (p = 0.34 and p = 0.47, respectively). Strong negative correlations were noted between the age of the donors and the sural nerve CSA (r = -0.69, p = 0.02), as well as the number of nerve bundles (r = -0.57, p = 0.06). Conclusions: This study shows that there are no statistical differences between the CSA and the number of nerve bundles in the sural nerve when compared by gender and side of the lower limb. This study also allows drawing the conclusion that the sural nerve degenerates with age in terms of both the CSA and the number of nerve bundles. (Folia Morphol 2014; 73, 3: 292-297)
Introduction. The aim of the study was to assess the impact of 10 weeks of bodyweight training on selected elements of body composition (body mass, muscle mass, and the percentage of body fat and water) and components of physical fitness (strength, strength endurance, flexibility, and aerobic capacity) of women aged 21-23 years who do not practise sports professionally.
Material and methods. The study involved 15 women whose mean age was 22 years 2 months. Their body mass and composition were assessed using a TANITA BC-1000 scale, and the following parameters of physical fitness were measured: the strength and power of the upper and lower extremities; the strength endurance of the shoulders, shoulder girdle, and trunk; as well as their flexibility and physical capacity. The assessment was performed twice, that is before and after the completion of the 10-week programme.
Results. The study revealed that the 10-week bodyweight training programme had caused a minor increase in body mass (1.16%) and body fat percentage (2.43%), while muscle mass and body water percentage had not changed. As far as physical fitness is concerned, the bodyweight exercises had had a positive impact on all of the elements of physical fitness which were measured, including statistically significant increases in the explosive strength of the lower extremities (5.6%; p<0.01), strength endurance of the trunk (10.7%; p<0.01), and aerobic capacity (33.3%; p<0.05).
Conclusions. Without a properly balanced diet and nutrition control, the bodyweight training programme had a small impact on the parameters of body composition. It was, however, an effective way of enhancing general physical fitness: apart from improving muscle strength and endurance, it also increased physical capacity and flexibility.

The paper aims to present diagnostic methods and options of conservative treatment of traumatic injuries of medial meniscotibial ligament (MTL). Ca. 75% of all sport-related injuries pertains to the lower extremity; among those, knee damage the second most frequent, after ankle damage. The anteromedial part is where knee pain occurs most frequently.
Knee injuries often lead to damage to ligament structures, including medial meniscotibial ligament, which is rarely reported in the literature. Those ligaments may be damaged when the knee is subject to forces leading to valgity and rotation of the femur, internally, and of the tibia, externally. Damage may be caused in an isolated manner, through overloads and combined microdamage.
Medial meniscotibial ligaments are formed by a fibrous layer of the articular capsule and are a part of the deep medial collateral ligament. They run from the medial meniscus to the proximal part of the tibia.
An MTL examination consists of three parts: medical interview, physical examination and additional examinations. Due to the structure of MTL, its diagnostics must be expanded by an examination of the anterior cruciate ligament (ACL), medial collateral ligament (MCL) and the medial meniscus.
Treatment in the acute condition is carried out according to the PRICE (Protection, Rest, Ice, Compression, Elevation) rules. In the subacute and chronic condition, therapy may be expanded for instance by manual therapy methods, functional training, physical therapy and kinesiology taping.
