Summary of a study investigating the influence of rest length on snatch performance.
Who
15 male athletes aged 23.0±2.31 years with a ratio of 1RM snatch to body weight at 0.78±0.12 with at least 6 months of experience (Malaysia).
Design
Experimental study: 4 visits in a laboratory (each session separated by 72 hours):
- session 1: 1RM snatch
- session 2-4: 3 sets of 5 reps of snatch at 85%, 5 minutes rest between sets, 10s or 30s or 50 s rests between each rep.
Outcome measures/tests
- peak velocity at ankle, knee, and hip
- ground reaction force
Main results
In the first pull, rests or repetitions did not significantly affect ankle, knee or hip joint velocity, apart from the case when angular velocity decreased between 1st and 5th rep at 10 seconds rest.
In the second pull, rests or repetitions did not significantly affect ankle and hip joint velocity, apart from the case when angular velocity decreased between 1st and 5th rep at 10 seconds rest. Knee velocity was not affected by rests or repetitions.
Peak ground reaction force did not change with the rest length changes. Peak ground reaction force reduced between 1st and 5th repetition at 10 seconds rest.
