Effects of Lour Cheese Consumption on Indicators of Physical and Skill Fitness of Volleyball Girls: An Experimental-Interventional Study

Volleyball is one of the most famous and popular sports worldwide, which needs high physical fitness and skills. Nutrition is an important factor in achieving this goal. Therefore, the aim of the current study was to assess effects of lour cheese consumption on indicators of physical fitness and skills of volleyball girls.

This study was semi-experimental study. In total, 36 teenage girl volleyball players with age ranges of 13–16 years were randomly divided into two groups of specialized exercises (18 people) and specialized exercises with the consumption of lour cheese (18 people). Specialized exercises were carried out for 90 min a day, three days a week, for six weeks. Lour cheese was consumed only on training days in two servings, one serving with food (25 g) and one serving immediately after training (25 g). Physical fitness and skill indicators were assessed before and at the end of the study. Analysis of covariance test was used to compare data changes between the two groups.

Results showed that consuming lour cheese for six weeks with specialized volleyball training included positive effects on the variables of peak power, agility, upper limb strength, lower limb strength, aerobic capacity, spike and functional tests, compared to that the specialized training alone did. However, no significant differences were observed in the variables of speed and service between the two groups.

Lour cheese can be used as a cheap supplement to further improve physical fitness and skill indicators in teenage girl volleyball players.
