Vrednovanje ronilačkih zadataka studenata Kineziološkog fakulteta
Basic principles of free diving are taught as part of the swimming classes at the Faculty of Physical Education in Zagreb. The theory lecture takes 2 hours, while the practical work is carried out through 8 hours of pool classes. As part of the diving classes the students are introduced to basics of free diving. The framework program includes: usage of fins, mask and snorkel, swimming technique with fins, mask and snorkel, equalization of pressure, breath holding, the vertical dive, orientation under the water, diving in depth and distance, equipping under the water, breathing technique directly before submersion and surfacing method. Preliminary exam in free diving consists of four tasks: the vertical dive, orientation under the water (spirals), equipping under the water and length dive. The primary aim of this research was to establish if the diving classes can lead to positive changes in apnea, and if the length of time one holds his breath under water could influence the success of performing diving tasks. The research was carried out on a sample of 85 students Faculty of Physical Education. Prediction variables are apnea after inspiration, apnea after expiration, length dive and vital capacity. Criterion variables are the vertical dive, spirals and equipping under the water. We conducted a t-test of difference for dependent samples in order to test the significance of difference between initial and final condition. After this we conducted a regression analyses for determining the significance and relative magnitude of influence of prediction sets (the vital capacity, apnea and length dive) on the criterion variable (the evaluation of diving tasks). According to the research results it can be concluded that the students have significantly improved their initial results of apnea and length dive after eight hours of practical diving classes. Evaluations of diving tasks they achieved at the end of the classes have the expected middle and even higher values, which speaks to the appropriateness of set diving tasks for student population. Influence of apnea on the performance of diving tasks proved significant only when performed after inspiration and even then it was rather modest. The vital capacity, as lung capacity, did not manifest a significant influence on any diving tasks.
