# Relationship between Physical Factors and Change of Direction Speed in Team Sports
## 4 Conclusions  
The literature showed the relationship between CODS and linear sprint speed, jump ability, and muscle strength. However, our review found some specifications for this relationship. The CODS significantly correlated with the sprint time for 10 m, 20 m, and 30 m, but not with the time for the shorter sprint (5 m). The 5 m sprint was included in a small number of studies. However, these short sprints are usually not very common in team sports, whereas sprints for longer distances are. This relationship was stronger if the CODS tests contained a similar running distance to the linear sprint test.  
The CODS also correlated with maximal leg strength, both explosive and reactive. However, the strength of the relationship between the CODS variables and the variables of physical fitness tests depends on the structure of the CODS test (the total distance, lateral running, the number of changes in direction, and the distance of linear running between these changes in direction) and the parameters analyzed, such as height, average or peak power, average or peak force, velocity, RSI, etc.  
Interestingly, while parameters of reactive strength (height, RSI) correlated with CODS in both genders, explosive strength correlated in female rather than in male players. Furthermore, the CODS tests that included longer running distances or changes of direction of high angle were associated with maximal leg strength, rather than with CODS tests that included shorter running distances.  
In addition, CODS performance showed a stronger relationship with strength parameters in relative values rather than in absolute values. The obtained parameters from the strength tests should be assessed with respect to body weight.  
An analysis of the literature identified gaps in research studies so far, which have not always focused on choosing the most appropriate tests and analyzed parameters. Selected tests should be close to the fitness demands of the particular sport. In addition to the already-mentioned specifications (the structure of the CODS test, and the parameters analyzed), gender and years of practice could also be considered.
