(Monday 18 April HealthDay News) - A rapid weight loss in the days before a game of catch can increase the confusion, but has no effect on the force, a new study finds.
American researchers examined the physical and mental effects of "weight cutting" in 16 collegiate wrestlers. Ten days before the competition, the wrestlers weighed and suffered psychological and stress tests. They could then choose a desired weight amount to lose before the match, using methods such as exercise, caloric restriction and fluid deprivation.
The wrestlers weighed again in the days before the match and psychology and strength tests were repeated on the day of the competition.
The wrestlers lost up to 8% of their body mass and average weight loss was approximately six books. Even if they had 10 days to lose weight, they have lost almost all their weight within two days before the match.
Researchers have discovered that wrestlers lost 4 percent or more of their body mass had significantly more high confusion on the day of the competition. No there was no confusion for those who have lost less than 4 per cent of their body mass.
Reduction of body mass has no effect on other psychological functions or grip strength or a lower body power, said researchers at the California State University at Fullerton.
The study is published in the April issue of the Journal of Strength and conditioning research.
It is common for the wrestlers to reduce body mass before a meeting to try to gain a competitive advantage in their weight class, but in "a sport which requires instant decision, a State enjoyed confusion and tension can affect investigations performance of wrestler" researchers noted in a press release of journal.
