Fin swimming (F.S.) is characterized by the application of athlete’s leg in single fin and the promotional movement due
to vacillation. It is not known whether the way of technique application of F.S., influences the concentrations of bone
metabolism hormones (1,2,3).
The aim of this study was to evaluate the serum concentrations of bone metabolism hormones in adolescent athletes of
F.S., after annual training program.

Eleven athletes of F.S., (age:18±2 years) participated in this study. The athletes training with an annual program by the
following characteristics: preparatory period of 29 weeks (mean volume of training: 50 ± 20 Km/w) and pre competition
season of 7 weeks (mean volume of training: 12 ± 7 Km/w) with the same intensity and frequency of training, followed
by the competition season. Three blood tests took place: at the beginning of preparatory period, at the beginning of pre
competition season and at the end of competition season in order to measure concentrations of following hormones
parathormone (PTH) and osteocalcine (BGP) via radioimmunoassay. For the statistical analysis ANOVA method wasused.

There were no significant differences among the three measurements (p>0.05).

Fin Swimming despite the training load during the training program, there were no differences onto hormones
concentrations levels influenced bone metabolism (4). Further research is necessary.
