A randomized control feasibility trial conducted at a UK residential care home found that a six-week machine-based resistance training program benefitted participants, compared...
by University of Central Lancashire Credit: University of Central Lancashire Whilst ice baths are popular with many athletes to aid recovery, new research published in the scientific journal Sports Sciences for Health suggests that many people might not see the expected benefits because they’re not doing it correctly. The study, led by researchers from the University of Central...
