The aim of the present study was to investigate whether street basketball organized as 3 v 3 on either a half court (HC) with 1 basket or a full court (FC) with 2 baskets could improve fitness and health profiles of untrained men after 3 months of supervised training.
Thirty-five untrained men (aged 20-42 years) completed the pre- and post-intervention testing (FC: = 13, HC: = 12, CO (control): = 10). The training attendance was 2.0 ± 0.4 and 1.9 ± 0.3 times per week in FC and HC, respectively. Mean heart rate (HR) was 83.8 ± 6.0 percent of maximal heart rate (%HR) and 84.5 ± 2.9 %HR in FC and HC, respectively.
The 3 months of street basketball training on an FC with 2 baskets increased maximal oxygen uptake (2.4 mL/min/kg (95% confidence interval (CI): 1.0-3.9)), time to exhaustion (47 s (95%CI: 26-67)), lean body mass (0.8 kg (95%CI: 0.1-1.5)), and bone mineral density (0.021 g/cm (95%CI: 0.011-0.031)), whereas mean arterial pressure (-5.6 mmHg (95%CI: -7.5 to 3.7)), body fat percentage (-1.6%, (95%CI: -2.5 to -0.7)), heart rate (-18 bpm (95%CI: -24 to -12)), and blood lactate (median: -1.4 mmol/L (interquartile range: -1.5 to -0.6)) during submaximal running were lowered. The changes were less pronounced after the training period when playing on an HC with 1 basket, but increases in maximal oxygen uptake (1.6 mL/min/kg (95%CI: -0.1 to 3.3)), time to exhaustion (28 s (95%CI: 9-47)), lean body mass (1.3 kg (95%CI: 0.3-2.4)), and lower body fat percentage (-0.9% (95%CI: -1.9 to -0.1)) were observed in this group.
Three months of 3 v 3 street basketball training improved fitness and led to broad-spectrum improvements in variables related to overall health profile, with the most marked effects observed when playing on an FC with 2 baskets.
本研究旨在调查,对于未经训练的男性,在有1个篮筐的半场(HC)或有2个篮筐的全场(FC)进行3对3的街头篮球训练,经过3个月的监督训练后是否能改善他们的体能和健康状况。
35名未经训练的男性(年龄20 - 42岁)完成了干预前后的测试(FC组:n = 13,HC组:n = 12,CO(对照组):n = 10)。FC组和HC组的训练出勤率分别为每周2.0 ± 0.4次和1.9 ± 0.3次。FC组和HC组的平均心率(HR)分别为最大心率的83.8 ± 6.0%和84.5 ± 2.9%。
在有2个篮筐的FC场地进行3个月的街头篮球训练,可提高最大摄氧量(2.4毫升/分钟/千克(95%置信区间(CI):1.0 - 3.9))、力竭时间(47秒(95%CI:26 - 67))、去脂体重(0.8千克(95%CI:0.1 - 1.5))和骨密度(0.021克/立方厘米(95%CI:0.011 - 0.031)),同时降低次极量跑步时的平均动脉压(-5.6毫米汞柱(95%CI:-7.5至3.7))、体脂百分比(-1.6%,(95%CI:-2.5至-0.7))、心率(-18次/分钟(95%CI:-24至-12))和血乳酸(中位数:-1.4毫摩尔/升(四分位间距:-1.5至-0.6))。在有1个篮筐的HC场地训练后,这些变化不太明显,但该组的最大摄氧量(1.6毫升/分钟/千克(95%CI:-0.1至3.3))、力竭时间(28秒(95%CI:9 - 47))、去脂体重(1.3千克(95%CI:0.3 - 2.4))有所增加,体脂百分比降低(-0.9%(95%CI:-1.9至-0.1))。
3个月的3对3街头篮球训练改善了体能,并使与整体健康状况相关的各项指标得到了广泛改善,在有2个篮筐的FC场地训练时效果最为显著。
