The Impact of Sport-discipline and Sex on Physical Fitness and Bone Markers in Athletes
This study was performed to determine the impact of sex and sport-discipline on
physical fitness and bone markers in young sub-elite track and field athletes.
One hundred and forty-four track and field sub-elite athletes (78 males
aged 17.8±1.6 years; 66 females aged 17.2±1.9 years) volunteered
to participate in this study and were categorized according to their disciplines
in endurance (EG: n=67) or power athletes (PG: n=77). A
significant main effect of sex was observed for C-telopeptide type I collagen
(CTx) (F=11.37; p<0.001; η2=0.10,
moderate), for osteocalcin (OC) (F=8.58; p<0.004;
η2=0.09, moderate) and for N-terminal propeptide
of procollagen type I (PINP) (F=7.96; p<0.05;
η2=0.07, moderate). The average CTx, OC and P1NP
levels were significantly higher in males compared with females
(0.05<p<0.001; η2= 0.07 to 0.10,
moderate). In addition, a significant main effect of sport-discipline was
observed only for P1NP values (F=10.16; p<0.002;
η2=0.09, moderate) with EG showing higher levels
than PG. For jumping and sprinting tests, the PG performed better than the EG.
For the endurance test, EG had better performance than PG. Endurance and power
exercise practices can increase bone formation markers (P1NP, OC), but only
anaerobic training (PG g...
