Land/Water
Strength In Swimmers
Strength is an essential physical quality for
swimmers in short distances. Sprinters are
typically stronger than distance swimmers. They
spend more time developing strength on land. This
is because sprinters need more strength to swim
faster for short distances. Sometimes they spend
about 40% of workout time on dryland. Is it enough
or too much? Testing of swimmers in land/water
strength helps answer these questions.
Testing
methodology
Land/water strength is carried out using a
tensiometer. Strength is measured in four
positions: on dryland in the middle of stroke, in
water performing pulling, kicking and full body
swimming. On dryland, with the use of a
tensiometer, the athlete applies a maximum effort
during an isometric contraction on a swim bench,
while in the water the athlete aims to stretch the
maximum length of a rubber cord with all-out
efforts during the pull, kick, and swim.

The DPSH digital
tensiometers represent the latest technology in an
affordable, feature packed instrument. The rugged
metal housing is durable enough to withstand harsh
environments. The easy to read display tells you at
a glance the unit of force measurement (lb, kg, or
Newtons), tension or compression, Peak Mode, and
whether the NiCad batteries are low. The standard
outputs (RS-232C, Digimatic, and ±1VDC analog) allow
you to capture data for permanent record. Choose the
range or ranges that best suit your needs. DPSH
tensiometers are sold complete in kit form with
gauge, hard plastic carrying case, full set of
measuring adapters, extension rod, and AC
adapter/charger. |
