”Statistics are no substitute for judgement.”
– Henry Clay –
The hip joint, along with the shoulder, is the most mobile joint on the human body. If we take into account the nature of handball and its requirements, the hip is important for the successful performance of many elements of the game (movement in attack and defence, performance of throwing elements, reflections, landings, slowdowns, stops, changes of direction etc).
Reduced mobility of the joint, which is very mobile by nature, leads to limitations in movements, i.e. sports performance, which creates imbalances in the body that often lead to injuries.
The aforementioned measurements show that playing handball is associated with reduced hip mobility, and the implementation of an additional program to develop a wider range of abilities contributes to a more harmonious development of the body.
Such a body will enable the handball player to maximise the manifestation of forces in all movements, stopping and control over them, which will lead to better performance of handball elements, longer sports career and higher life quality after a sports career.
The experimental group of non-handball-type training in childhood (gymnastics, athletics, power, strength, coordination etc) successfully maintains the level of internal hip rotation in a non-invasive manner (hip mobility exercises were not performed).
Further longitudinal research is needed to determine at what age limitation of the amplitude of movement in the hips begins to form, and what is the long-term impact of corrective programs on this ability.
The lack of research is the small number of scientific papers on the impact of sports on hip mobility in young athletes.
Simultaneously with the research on men, the measurement of all age categories was carried out in the women’s professional club RK “LOKOMOTIVA” and the measurement results are in the following table.
Hips were expected to be more mobile in women than in men, as measurements show.
What is interesting is the almost equal internal hip rotation in all age categories, and the fact that this mobility is higher than average, which in some resources is associated with knee injuries.
Table no. 2 shows the ratio of internal hip rotation for all groups listed in the study:
