Insufficient rest/recovery
When rowers overload during training, the adaption to the muscle occurs during the recovery period and not during the actual training. However, if they do not allow sufficient recovery period for the adaptation to take place, they may be fatigued when they start their next training session. So, it’s imperative that sufficient rest periods are built into a rower’s training programme to enable adequate recovery.

Muscle glycogen depletion
Muscle ATP levels are maintained by aerobic and anaerobic breakdown of muscle glycogen. However, glycogen stores are limited and are depleted quickly with increasing exercise intensity, which causes muscle fatigue.
Both short and long muscle twitch fibres use glycogen. Short twitch fibres are first to use glycogen and can go for a long time before they fatigue. Fast twitch fibres on the other hand, fire more rapidly and are more effective at producing quick burst of strength but fatigue quicker.
Muscle glycogen stores however can be increased through endurance training, normally in conjunction with a high carbohydrate diet.

Insufficient replenishment of energy resources
Carbohydrates are the body’s main source of rapidly available energy. This is because they are converted more readily into glucose than protein or fats. Glucose flows in the bloodstream so that it is available to every cell in the body. Cells absorb glucose and covert it into energy. However, a failure to replenish energy resources can delay recovery time and bring-on fatigue. However, carbohydrates and energy drinks taken before a race will increase the amount of fuel stores in muscle, which in turn improves performance, delays the onset of fatigue and aids post exercise recovery.

Insufficient hydration
Keeping sufficiently hydrated before, during and after exercise is important, especially to replace fluid that is lost through sweating. Fluid losses of as little as 2% of body weight can impair performance in speed and strength, increase fatigue and delay recovery.

PCr and fatigue
Creatine phosphate (PCr) plays an important role in brief maximal muscle action. However, the availability of creatine in the body is limited (10 seconds) and as PCr decreases, rowers increasingly have to rely on the aerobic system to produce energy. This relative short availability of PCr may not be sufficient to provide the necessary acceleration required during the start of a race.
