Adults from many communities who value unstructured, outdoor play and want to play have limited resources to engage in play (Talarowski et al., 2019). Many parks and playgrounds today are designed with children in mind and do not offer many adult-friendly play options. The purpose of this exploratory study was to examine outdoor and indoor adult play preferences to establish a baseline for adult play or nature space design. The survey was distributed to male (N=61) and female (N=261) 18–80-year-old participants through email and posts on Facebook, Instagram, and Twitter and given a three-week window to complete. The participants were asked to pick their five top activity preferences. Overall, 33% of the participants preferred nature activities, 24% preferred playground equipment, 22% preferred sports, and 21% preferred large-yard games. The top preferences predominately came from nature activities and large-yard games. Responses from write in questions showed this group of participants preferred being outdoors (84%), active (85%), and socially driven (97%). More opportunities that match these specific preferred activities must be considered so that adults can take full advantage of the benefits play can provide.

The purpose of this study was to measure the acute effects of resistance training (RT) protocols with a different number of sets and non-equalized volume on muscle thickness, peak force, and physical performance in recreationally-trained participants. Fifteen participants performed the unilateral biceps curl exercise in four different RT protocols (G4: 4 sets of 10RM, G8: 8 sets of 10RM, G12: 12 sets of 10RM, and G16: 16 sets of 10RM). The average number of repetitions (ANR), the total number of repetitions (TNR), time under tension (TUT), muscle thickness (MT), peak force (PF), and rating of perceived exertion (sRPE) were measured pre-test and post-test. ANOVAs were used to test differences between all dependent variables. For ANR, there were differences between G4xG8, G4xG12, and G4xG16 and between RT protocols for TNR (p<0.05). There were differences for all RT protocols and between G12 and G4, G8, and G16 for TUT (p<0.05). MT increased and PF decreased for all RT protocols (p<0.001). In conclusion, G8, G12, and G16 showed lower ANR than G4, TNR increased with increasing sets, and TUT increased in all RT protocols. PF decreased with increasing sets and all RT protocols increased MT. The sRPE was similar between RT protocols.

It is known that beetroot supplements may improve exercise economy and blood pressure, but this has mainly been studied in males. Given that older female athletes are underrepresented in the literature, we aimed to determine if acute beetroot supplementation (BRS) improves exercise economy and blood pressure in masters female athletes (swimmers) during a treadmill exercise test. Methods: 11 participants (57.8±10.5 y) underwent 2 randomized, double-blinded trials, ingesting beetroot (BE) or placebo (PL). Salivary NO2- (sNO2-) and blood pressure (BP) were measured pre-ingestion (Base), pre-exercise (Pre), and 5 min post-exercise (Post). Oxygen consumption (VO2) was measured during the modified Balke test until HR reached 85% of age-predicted maximum. Exercise economy (ExEc) was defined as the average relative VO2 during min 3-4.5 of the test. sNO2- was determined using NO2- detection strips. Results: sNO2- increased from Base to Post in BE vs PL (32.5±7.0 vs 2.7±3.9% change, p=0.001). No treatment differences existed for ExEc (BE: 15.51±0.47 vs PL: 15.71±0.53 ml·kg-1·min-1, p=0.48). Diastolic BP was significantly lower in BE vs PL (Base: 74.6±1.7 vs 73.2±2.3, Pre: 73.6±1.8 vs 74.5±2.1, Post: 74.5±1.7 vs 76.1±2.2 mmHg, p=0.03, treatment by time). Conclusion: Acute BRS lowered diastolic BP, but did not improve exercise economy in these trained, normotensive athletes. Further research is warranted in menopausal and post-menopausal females, including those who are hypertensive, and in other female masters athlete groups.
众所周知，甜菜根补充剂可以改善运动经济性和血压，但这主要是在男性身上进行的研究。鉴于老年女运动员在文献中的代表性不足，我们的目的是确定急性甜菜根补充剂(BRS)是否能在跑步机运动测试中改善高级女运动员(游泳运动员)的运动经济性和血压。方法:11名参与者(57.8±10.5岁)进行了2项随机双盲试验，分别服用甜菜根(BE)或安慰剂(PL)。测定摄入前(Base)、运动前(Pre)和运动后5分钟(Post)唾液NO2- (sNO2-)和血压(BP)。在改进的Balke试验中测量耗氧量(VO2)，直到HR达到年龄预测最大值的85%。运动经济性(ExEc)定义为测试前3-4.5分钟的平均相对VO2。采用NO2-检测条测定sNO2-。结果:在BE组和PL组中，sNO2-从基底到后端升高(32.5±7.0 vs 2.7±3.9%变化，p=0.001)。ExEc的治疗差异无统计学意义(BE: 15.51±0.47 vs PL: 15.71±0.53 ml·kg-1·min-1, p=0.48)。BE组舒张压明显低于PL组(治疗前:74.6±1.7 vs 73.2±2.3，治疗前:73.6±1.8 vs 74.5±2.1，治疗后:74.5±1.7 vs 76.1±2.2 mmHg, p=0.03，按时间计算)。结论:急性BRS降低舒张压，但不能改善训练后血压正常的运动员的运动经济性。在绝经期和绝经后女性(包括高血压患者)和其他女性大师级运动员群体中进行进一步的研究是有必要的。
