Table 1 Description of the baseline functional performance tests
Baseline tests | Description |
|---|---|
Single hop for distance [9] Outcome: maximum length from toe to heel (cm) Evaluates maximum single hop performance | Stand on one leg, jump as far as possible, land on the same leg, with a controlled, balanced landing. Three practice trials and 3 maximum attempts are allowed. If hop length increases in all 3 hops, additional hops are performed until no further increase occurs |
5-Jump test [10] Outcome: maximum length from toe to heel (cm) Evaluates lower limb explosive power | Stand on both feet, perform a series of 5 jumps with alternated left and right foot contact, and land with a controlled, balanced landing on both feet. Three practice trials and 3 maximum attempts are allowed |
Side hop [9] Outcome: maximal number of side hops where the foot is not touching the tape (n) Evaluates hop performance while developing fatigue | Jump on the test leg from side to side outside 2 parallel strips of tape 40 cm apart (with hands behind the back); perform as many jumps as possible for 30 s. If the foot touches the strips of tape, the hop is not valid. A few test hops are performed to get familiarized with the test. One maximum attempt was videotaped and analysed afterwards to count successful jumps |
