Cricket has evolved from a traditional and conservative sport to a fast-paced, vigorous game. As a
result of this the physical conditioning programmes of players have changed drastically with
regular fitness tests that are now an integral part of these programmes. In spite of this, no studies
have made an attempt to determine the exact relationship between the physical and motor ability
parameters of batsmen and their performance. The purpose of this study was, therefore, firstly to
determine which physical and motor ability parameters discriminate between successful and less
successful provincial academy batsmen and secondly, to determine how much these parameters
contribute to the batting performance of provincial academy batsmen.
Twenty-two batsmen from the Gauteng and North-West cricket academies in South Africa were used in this study. Thirteen batsmen (20.15 +- 1.41 years) participated during the 2004 season whilst
nine batsmen (21.11 +- 1.83 years) took part during the 2005 season. The players were subjected to
23 physical and motor ability tests, whilst 72 isokinetic measurements were also taken. The data
was analysed by means of descriptive statistics, cluster analyses, forward stepwise discriminant
analyses and finally forward stepwise multiple regression analyses.
The discriminant analyses showed that right (RKEPT) and left knee extensor peak torque (LKEPT),
right knee extensor average power (RKEAP), left knee extensor total work (LKETW) and left knee
flexor peak torque (LKFPT) (all at 30°/sec), as well as LKEPT, RKEPT and L.KEAP (all at
24O°/sec ), left (LIRAP) and right shoulder internal rotator average power (RIRAP). right shoulder
external/internal rotator peak torque ratio (REIRPTR) and right shoulder internal rotator peak
torque (RIRPTJ (all at 24O°/sec) as well as left shoulder internal rotator total work (LIRTW)
(60°/sec) discriminated non-significantly between the successfu1 (top 5 ranked batsmen of both
seasons) and less successful academy batsmen. The physical and motor ability parameters which
were identified as discriminators were left 505 agility, shuttle run aerobic endurance and IRM
(repetition-maximum) hack squat strength (all significant) (p 5<= 0.05) whilst left grip strength and abdominal muscle strength discriminated non-significantly. The forward stepwise multiple
regression analyses indicated that RKEPT 30' (16%). LKEPT 30' (7%), RKEAP 30' (7%), LKFPT
30' (7%), LKEAP 240" (6%), RKFPT 240" (5%). LKETW 30" (5%) and LKEPT240° (4%) were the
isokinetic knee strength parameters which contributed non-significantly to batting performance.
The isokinetic shoulder strength parameters which also contributed non-significantly to batting
performance were: RIRPT240° (28%). LIRAP 240' (16%), REZRPTR 240' (8%). LIRTW 60° (5%)
and RIRAP 240' (4%). Vertical jumping power (13%) (p 50.05), left 505 agility (9%) (p 50.05),
abdominal muscle strength (5%) (p 50.05), aerobic capacity (10%). IRM bench press strength
(7%), IRM hack squat strength as well as left shoulder internal rotation flexibility (4% each) were
the physical and motor ability parameters which contributed to batting performance. The
conclusion that can, therefore, be drawn is that physical and motor ability parameters contribute to
the performance of provincial academy batsmen and that these components should be included in
the physical conditioning programmes of batsmen / Thesis (M.Sc. (Human Movement Science))--North-West University, Potchefstroom Campus, 2007.
