Flexible Nonlinear Periodization in a Beginner College Weight Training Class. J Strength Cond Res 2009— Determine the effect of a flexible nonlinear (FNL) periodized weight training program compared to a nonlinear (NL) periodized weight training program on strength and power RCT of 16 beginner weight training students (12 males) (age range: 18 – 23 years) assigned to an FNL group (n = 8) or an NL group (n = 8). The exercise program included a combination of machines and free weights completed in 30 minutes, twice per week, for 12 consecutive weeks. Both groups were assigned the same total training volume of 3,680 repetitions and the same total training repetition maximum assignments of 10, 15, and 20. The FNL group, however, was allowed to choose which day they completed the 10, 15, or 20 repetition workout. This was the only difference between the groups. Pre- and post-test measures included chest press, leg press, and standing long jump. Leg press strength was significantly greater in the FNL group The FNL group did not significantly differ in chest press or standing long jump performance when compared to the NL group Determine: 1 RM (direct test) Estimated 1 RM from multiple RM test Multiple RM based on goal or target reps Warm up: easy 5 – 10 reps: 1 min rest Add 5 – 10% or 10-20lbs (UE) or 10-20% or 30-40lbs (LE): 3 -5 reps: 2 min rest 3. Add another 5 – 10% or 10-20lbs (UE) or 10-20% or 3040lbs (LE): 2-3 reps: 2-4 min rest 4. Add another 5 – 10% or 10-20lbs (UE) or 10-20% or 3040lbs (LE): 5. Attempt 1RM: if successful rest 2 -4 min and repeat step 4 6. If failure: rest 2-4 minutes: 1. 2. Reduce load by 5-10lbs or 2.5% to 5% (UE) Reduce load by 15-20lbs or 5% to 10% (LE)Repeat step 5 7. Attempt to achieve a max test in 3 – 5 test sets Good for testing muscles in isolation and compound Test isolation exercises at ≥ 8 RM May want use higher RM for untrained (10RM) Try to avoid multiple high rep and warm up sets due to fatigue especially with compound / multiple group mm exercises Power ex RM test > 5 for multiple sets is not appropriate Test a lower RM for more trained persons (individuals training with heavy loads for a few months) for improved accuracy Test protocol similar to the 1RM test but load changes are ~ one half less Pick a weight that the individual can do a RM 10 or less times Isolation exercises ≥ 8 RM Tables vary depending on the literature cited More predictive of 1RM the heavier the load (less reps) % 1 RM No. of reps 100 1 95 2 93 3 90 4 87 5 85 6 83 7 80 8 77 9 75 10 70 11 67 12 65 15 Determine the reps that will be actually used in the program Test to see what weight can be lifted for the target number of reps Try to avoid excessive multiple set high rep testing of large mm groups due to fatigue Isolation exercise should be tested at no less than 8 RM
