• Sir Leonard Hutton Fitness Guidelines
• Each player is responsible for his own fitness
• He must be well rested and must not over train
  in practice
• He should exercise only very mildly on off days
• He may swim, play tennis or golf in the early
  morning
• He must stay out of the midday sun
• 1986 Edition Of The Lord Taverners Cricket Clinic
  
• To develop stamina run, skip or cycle 10 to 20
  mins in season
• To develop strength push up, sit ups and
  swing the bat
• To enhance mobility, wide stride sitting, toe
  touching and head and
• shoulder circling

Duration of Activity
Postulated contributions ( of total energy) from
the different metabolic energy systems used
during activities lasting different durations.
Note the predominant contribution from
oxygen-independent glycolysis and the phosphagens
in activities of short duration (less than 40 s)
typical of cricket
