Effects of a 16-week recreational team handball intervention on aerobic performance and cardiometabolic fitness markers in postmenopausal women: A randomized controlled trial

Background: Postmenopausal women have an elevated risk of developing cardiovascular diseases, which can be counteracted by conventional exercise regimes or recreational football. Less is known about the impact of exercise programmes based on other team sports. Thus, we examined the effects of recreational team handball on aerobic performance, cardiorespiratory fitness and cardiometabolic health in untrained postmenopausal women. Methods: Sixty-seven participants (age 68 ± 6 years, stature 157 ± 6 cm, body mass 67 ± 10 kg, fat mass 37 ± 7%, VO_2peak 25.2 ± 3.6 mL/min/kg, Yo-Yo intermittent endurance level 1 test performance (YYIE1) 230 ± 103 m) with no previous experience of team handball were randomly allocated to either a team handball (THG, n = 41) or a control (CG, n = 26) group. THG performed 2–3 60-min training sessions per week for 16 weeks. YYIE1 performance and cardiometabolic markers were evaluated at baseline and post-intervention. Results: Average attendance during recreational team handball training was 1.9 ± 0.4 sessions per week, with mean heart rates of 76 ± 6%HR_max and 18 ± 9 min (44 ± 20% of total time) played at HR > 80%HR_max. A between-group effect was observed for YYIE1 performance, with a more pronounced improvement in aerobic exercise performance in THG compared to CG (70 ± 62 vs 15 ± 44%; p < 0.001). Within-group improvements (p < 0.05) were observed for THG with regard to VO_2peak (7 ± 10%), incremental treadmill test time to exhaustion (TTE) (11 ± 14%), total cholesterol (−3 ± 9%) and low-density lipoprotein cholesterol (−2 ± 14%), with no significant changes in CG except an increase (p < 0.05) in TTE. Post-intervention values were higher for THG vs CG for YYIE1 performance (88%; 406 ± 216 vs 216 ± 75 m) and VO_2peak (10%; 27.5 ± 3.8 vs 24.9 ± 3.6 mL/min/kg). Conclusions: Recreational team handball can be used to obtain moderate-to-vigorous aerobic intensities, and just 2 weekly 60-min team handball training sessions for 16 weeks can result in improvements in aerobic performance and in markers of cardiorespiratory fitness in postmenopausal women with no previous experience of the sport.
