Swine Flu Parties
Swine flu parties are being held in order to maximize resistance according to reports heard by the chairman of the British Medical Association’s public health committee.
Dr Richard Jarvis says that people are intentionally mixing with the sick in order to contract the flu before it becomes more deadly as winter progresses.While he admitted that getting the flu virus now was more likely to give sufferers immunity that if mutated it could become quite virulent and possibly life-threatening.
Walking Wonders
A new study has shown that walkers wanting a moderate intensity workout should be doing at least one hundred steps a minute.The recommended amount of physical exercise per week currently stands at 30 minutes, five days per week.
For walkers, this equates to around 3,000 steps in 30 minutes..
Sit-ups can harm the spine
Dr Richard Guyer of the Texas Back Institute is warning against sit-ups or crunches, especially for those with back problems.
When doing sit-ups or crunches, strain is dangerously placed on the back of the spine, where the most nerve endings are situated and when the back bend
s during exercise, opening the extended possibility of nerve damage.The damage caused through sit-ups and crunches occurs from exercise over time and can result in the herniation of spinal disks, which can cause severe back pain, tingling, weakness, paralysis and may even require surgical attention.
Stuart M. McGill, professor of spine biomechanics at the University of Waterloo says every time someone does crunches or sit-ups, “they are one repetition close to damaging the disk.”
According the experts, the best exercises involve working abs while keeping the spine straight such as planks, leg drops or pushups.
