Well in a nutshell this is the psychological and physical peaks of energy that you have over the period of a day. For example a person who regularly works a nightshift may be most awake at 3 am in the morning, as this is what their body clock equates to the middle of the day.
By depriving people of light and other external time cues, scientists have learned that most people's biological clocks work on a 25-hour cycle rather than a 24-hour one. But because sunlight or other bright lights can reset the SCN, our biological cycles normally follow the 24-hour cycle of the sun, rather than our innate cycle. Circadian rhythms can be affected to some degree by almost any kind of external time cue, such as the beeping of your alarm clock, the clatter of a garbage truck, or the timing of your meals. Scientists call external time cues zeitgebers (German for "time givers").

Achieving results from training comes down to the correct training at regular intervals and regular times. So when training in a regular time frame of approximately 3 hours, the body may best adapt and be prepared for that effort. So put simply try where possible to train at the same time on the same days where possible.
This is the explanation for persons that regularly train in the evening finding it difficult to train at 6 am in the morning.
However within seven days of changing this trend the body should adapt. For example changing from a night shift to a day shift or changing time zones whilst travelling.
Strokes are increasingly common every year 150,000 people in the UK have one. It is also the third most common cause of death in the UK.
Around 80% of strokes are caused by a sudden blockage of a blood vessel in the brain and 20% by are caused by a burst blood vessel. Strokes are not limited to older generation they are less common but also occur within young adults. Long term problems associated with strokes are depression, fatigue, confusion, limb issues, seizures and incontinence.
There is an increasing body of evidence from several research trials that physical fitness training after a stroke improves physical fitness, function (e.g. walking) and psychological function. Another key finding was that many of those trailed perceived regular physical exercise as the key to 'getting back to normal' and 'regaining confidence'.
Results from research showed the most effective training was a mixture of aerobic and strength training. Frequency and intensity of training is dependant upon each affected person and should be individually assessed.
