muscle strength, power, muscle architecture, and performance in

2728-2736, 2021-The purpose of the study was to investigate the effect
of a 25-week macrocycle on strength, power, vastus lateralis (VL) muscle
architecture, and competitive track and field throwing performance, in
well-trained track and field throwers. Twelve well-trained throwers
(age: 24.3 +/- 5.5 years, mass: 96.6 +/- 9.9 kg, and height: 1.82 +/-
0.02 m), participated in the study. All athletes followed a 25-week
periodized training program divided into 3 training phases: the
hypertrophy/maximum strength phase, the maximum strength/power phase,
and the power/speed phase. Measurements were performed at the beginning
of the training period (T1), after the first training phase (T2), and
after the end of the training period (T3). Measurements included the
following: competitive track and field throwing performance; shot put
throws; maximum strength (1-RM) in snatch, clean, and squat;
countermovement jump (CMJ); and VL muscle architecture. Competitive
track and field throwing performance and shot put throws increased from
T1 to T3 by 10.9 +/- 3.2% (p = 0.001) and 5.1 +/- 6.4% (P = 0.049),
respectively. 1 RM strength in snatch and squat increased significantly
from T1 to T3 by 9.7 +/- 8.9% (p = 0.001) and 9.9 +/- 7.1% (p =
0.002), respectively. Countermovement jump height increased only from T1
to T2 by 10.9 +/- 11.8% (p = 0.026). A significant increase was found
for VL fascicle length between T1 and T3 (9.6 +/- 11.1%, p = 0.049).
Strong correlations were found between the percentage increase of
competitive track and field throwing performance with 1 RM snatch (r =
0.571, p = 0.046) and with shot put throws (r = 0.715, p = 0.001).
Twenty five weeks of training may increase performance and VL fascicle
length, whereas increases in 1 RM snatch and in shot put throws are
associated with competitive track and field throwing performance in
well-trained throwers.
