O Eddy Merck όταν ήταν χορηγός αμερικάνικης επαγγελματικής ομάδας ποδηλάτου παρατήρησε τους αθλητές της ομάδας και συμβούλευσε σχεδόν όλους να ανεβάσουν το ύψος της σέλας. Ένας από αυτούς αποφάσισε να αγνοήσει τις συμβουλές του και να διατηρήσει την σέλα στο ίδιο σημείο/ ύψος. Οταν ο Merckx τον συνάντησε ξανά του είπε να κατεβάσει την σέλα λίγο.
Είναι σαφές ότι η παρατήρηση δεν μπορεί να μας δώσει ασφαλή συμπεράσματα εάν ένας αθλητής κάθεται ή όχι σωστά πάνω στο ποδήλατο. Ακόμα και ένας κορυφαίος ποδηλάτης όπως ο Eddy Merckx πέφτει έξω και κάνει λάθη. Είναι σαφές ότι η παρατήρηση δεν είναι ένας σοβαρός τρόπος προσέγγισης αυτού του βασικού για την ποδηλασία ζητήματος.
O “μοναδικός” Graig Lemond (3 φορές νικητής του Γύρου Γαλλίας και αθλητής με 90ml/ kg/ min VO2 max) πιστώνεται τον τύπο : Υψος Σέλας = 0,883 Χ Υψος Καβάλου.
Ως ύψος σέλας θεωρούμε την απόσταση της μεσαίας τριβής από το πάνω ύψος της σέλλας (μέσο της σέλας).
(Σημείωση : Αυτός ο τύπος βέβαια είναι προιόν της σκέψης του προπονητή του LeMond του Cyrille Guimard).
Μερικές παρατηρήσεις :
- Ο παραπάνω τύπος μας δίνει ένα καλό σημείο εκκίνησης από τον οποίο μπορούμε να κάνουμε σχετικές αλλαγές. Οι οποιεσδήποτε αλλαγές πρέπει να είναι σταδιακές. Προτείνουμε να γίνονται σταδιακά αλλαγές των 5mm κάθε φορά.
- Οι σωματικές ιδιαιτερότητες, το μυικό σύστημα, ο τρόπος πεταλαρίσματος, το είδος αγώνων που συμετέχει ο αθλητής, το τυχόν ιστορικό τρυματισμού κ.λπ. θα καθορίσει τις αποκλίσεις από αυτό τον τύπο.
- Στο ίδιο σημείο καταλήγουμε εάν εφαρμόσουμε και άλλες θεωρίες όπως αυτή του Andy Pruitt σχετικά με την γωνία στο γόνατο, που μας υποδεικνύει ότι πρέπει να είναι 25 μοίρες. Φυσικά η γωνία στο γόνατο δεν μπορεί να είναι μεγαλύτερη από 35 μοίρες
- Το 0,883 προτείνεται να γίνει 0,90 ακόμα και 0,92 εφόσον ο αθλητής ποδηλατεί όχι με το πέλαμα παράλληλα με το έδαφος αλλά με τα δάχτυλα να δείχνουν προς το έφαφος.
- Σε αθλητές με σοβαρή χονδροπάθια η Αμερικάνικη Ακαδημία Ορθοπαιδικών Χειρουργων προτείνουν να κάθεται ο αθλητής ακόμα πιο ψηλά (15 μοίρες γωνία)
