STRENGTH TRAINING 4
This first issue of Volume 11 of Coaching Science Abstracts reviews articles concerned with strength and resistance training and stretching. The first issue of strength training can be accessed as Volume 2(1), the second as Volume 5(1), and the third as Volume 8(1). These latest researches indicate that many of today's strength training practices are incorrect and the benefits from such training is greatly exaggerated.
