Purpose:The present study evaluated the effects of regular participation in small-sided team handball training on body composition,osteogenic response,physical performance,and cardiovascular risk factors,as well as well-being and motivation,in young untrained women. Methods:Twenty-eight untrained 20-to 30-year-old women were randomized to a handball training group(HG;n=14,height 170 ± 5 cm,weight 73 ± 11 kg,VO2peak37.7 ± 4.1 mL/min/kg)that trained 1.7 ± 0.3 times per week over 12 weeks(70 min 4 v 4 handball sessions)or an inactive con-trol group(CG;n=14,169 ± 5 cm,71 ± 12 kg,38.1 ± 3.7 mL/min/kg).Physiological and psychological and motivational training adaptations were assessed pre-and post-intervention by dual-energy X-ray Absorptiometry(DXA)scans,blood sampling,physical tests,and questionnaires. Results:The average heart rate(HR)over all training sessions was equal to 85% ± 6% HRmax.Between-group intervention effects were observed in favor of HG for muscle mass(2.1%,p=0.024),proximal femur bone mineral density(0.8%,p=0.041),Yo-Yo IE1 intermittent endurance test level 1(IE1)performance(35%,p<0.001),and incremental treadmill test performance(11.5%,p=0.003),but not total fat mass(p=0.176), mean arterial blood pressure(p=0.328),resting HR(p=0.219),or blood lipids(p=0.298-0.854).In CG,no changes were observed in any of the measured physiological variables after the training period.Compared to CG,HG had an increase in intrinsic motivation(p<0.001)and in the well-being subscaleenergy(p=0.010). Conclusion:Participation in regular recreational team handball training organized as small-sided games has marked beneficial effects on physical performance,musculoskeletal fitness,well-being,and motivation in untrained young women.
