Aim and method

Uneven development of speed-strength holds back results. Existing models (Novikov, Kuznetsov, Shustin 1976; Guzhalovsky, Alabin 1980; Oleshko, Mironenko 1980) need too many indicators and complex equipment.
Aim: simple control tests, their correlation with results, and a model profile for managing training.
Subjects: 25 Masters of Sport, 67.5 kg class, tested in the competition period. Tests: power snatch, power clean, push jerk, back squat, standing long and high jumps.

Results

Snatch: power snatch r = 0.81; power clean 0.56; squat 0.54; long jump 0.49; high jump 0.44. So jumps cannot be a main training means.
Clean and jerk: push jerk 0.88, power clean 0.83, squat 0.82; long jump 0.58, high jump 0.53.
Model for a 280 kg total (125 + 155 kg). As % of the snatch: power snatch 87 ± 5.2%, power clean 111 ± 11.2%, squat 166 ± 7.1%. As % of the clean and jerk: push jerk 86 ± 4.6%, power clean 89 ± 3.4%, squat 134 ± 6.5%. Falling short of a model value shows which quality needs work in the plan.

Circular model diagrams of speed-strength preparedness for the snatch and the clean and jerk — Figure. Model of the speed-strength preparedness of Masters of Sport in the 67.5 kg class needed for a 280 kg total. Top: **snatch 125 kg** in the centre, surrounded by power snatch (r = 0.81; 87 ± 5.2%), power clean (r = 0.56; 111 ± 11.2%), back squat (r = 0.54; 166 ± 7.1%), standing high jump and standing long jump. Bottom: **clean and jerk 155 kg** with push jerk (r = 0.88; 86 ± 4.6%), power clean (r = 0.83; 89 ± 3.4%), back squat (r = 0.82; 134 ± 6.5%), standing long jump (r = 0.58) and standing high jump (r = 0.53). Percentages are of the classic lift. In the snatch diagram the jump labels read long jump r = 0.44 and high jump r = 0.49 — the reverse of the article text (0.49 and 0.44).
