The maximal oxygen uptake and dynamic stability is frequently assessed separately for different team players. However, most research is limited to specific sports players, so the maximal oxygen uptake and dynamic stability in rugby and soccer players are poorly documented. This study provides relationship between maximal oxygen uptake and dynamic stability in university rugby and soccer players. Twenty-eight participants were recruited for the study (14 rugby players and 14 soccer players). Maximal oxygen uptake was determined by multistage fitness test and dynamic stability was determined by Y balance test. A linear regression analysis was used to identify relationship and effect of maximal oxygen uptake and dynamic stability on university rugby and soccer players. Both groups were similar in characteristics. Our findings showed there was a significant relationship between the maximal oxygen uptake and dynamic stability for rugby players (r=.890) and soccer players (r=.811). Relationship between maximal oxygen uptake and dynamic stability (r=.836) was significant for both sports players. Rugby and soccer players achieved good scores in maximal oxygen uptake and dynamic stability and high maximal oxygen uptake scores lead to better dynamic stability in both teams' players. Maximal oxygen uptake affects the dynamic stability. Team coaches and physiologists must consider functional test outcomes while preparing players for competition. The individual training program should also be established on test outcome, which is more likely to improve performance.
