女性运动员体能训练：生命周期、损伤与健康考量 Strength & Conditioning of Female Athletes: Lifespan, Injury, and Health

这是 NSCA 自 1989 年以来对女性运动员立场声明的首次全面重写，分为两部分发表。第一部分回答三个问题：女性运动员在整个职业生涯中经历了什么——从青春期前发育，经妊娠，直至绝经；哪些损伤不成比例地落在她身上；以及哪些健康议题应当进入体能教练的视野。第二部分讨论训练适应与计划设计。 This is the NSCA's first full rewrite of its 1989 female-athlete position statement, published in two parts. Part I answers three questions: what the female athlete experiences across her career — from prepubertal development through pregnancy and menopause; which injuries fall disproportionately on her; and which health considerations belong in a strength and conditioning coach's field of view. Part II covers training adaptations and program design.

证据标准：为什么「二级运动员」这条门槛重要The evidence standard: why the Tier 2 threshold matters

本声明尽可能只采纳二级（Tier 2）及以上运动员的研究——即每周约训练三次、以参赛为目的的人群。这条门槛至关重要：文献中大多数所谓的性别差异来自未受训练的样本，而在这类样本中，训练暴露量与性别是混杂在一起的。 The statement restricts itself, wherever possible, to research on Tier 2 athletes and above — people who train roughly three times a week with the purpose of competing. That bar matters: most claimed sex differences in the literature come from untrained cohorts, where training exposure and sex are confounded.

作者明确指出，性（sex）与社会性别（gender）的影响至少是部分交织的。一项被测量出的「性别差异」，可能被女孩在青少年体育早期所受的运动经历、机会与资源限制所混杂、调节或中介。这一判断贯穿两篇论文，其实践含义是：不要把可能源自训练史的现象归因于生物学。 The authors are explicit that sex and gender effects are at least partially intertwined. A measured "sex difference" may be confounded, moderated, or mediated by socially constructed differences in sporting experience, opportunity, and resourcing placed on girls early in youth sport. The practical consequence runs through both papers: do not attribute to biology what may be an artefact of training history.

一、生命周期1. Lifespan

青少年：决定计划的是成熟度，不是生日Youth: maturity, not birthday, drives programming

女孩对体能训练的反应性与男孩相似。耐力、抗阻、增强式与速度训练干预，均能带来超出自然生长的表现提升。声明建议训练应在青春期前开始——此时神经可塑性处于高位——以在有趣且积极的心理社会环境中，优先实现基本动作技能与肌肉力量的协同发展。 Girls' responsiveness to strength and conditioning is similar to that of boys. Endurance, resistance, plyometric, and speed interventions all enhance performance beyond what growth alone delivers. The statement recommends training commence in the prepubertal years, when neural plasticity is heightened, to prioritise the synergistic development of fundamental motor skills and muscular strength in a fun and positive psychosocial environment.

同一实际年龄的儿童，生物学成熟度最多可相差 5 岁。因此声明建议大约每 3 个月评估一次成熟状态。骨龄是金标准，但实践中推荐体格测量法——距身高峰值速度（PHV）的成熟偏移量，或已达成年身高百分比——因其无创、低成本且易于获取。 Children of the same chronological age can differ by up to 5 years in biological maturity. The statement therefore recommends estimating maturity status roughly every 3 months. Skeletal age is the gold standard, but somatic measures — maturity offset from peak height velocity (PHV), or percent of predicted adult height — are recommended in practice for being non-invasive, cheap, and accessible.

青春期后，女性运动员出现提高 ACL 风险的下肢运动学改变：更大的峰值外展角、更大的膝外展力矩峰值与内旋力矩。成熟期同时抬升过用性与生长相关损伤（塞弗病、胫骨结节骨骺炎、髌股疼痛）的发生率。 Post-puberty, female athletes show lower-extremity kinematic changes that raise ACL risk: higher peak abduction angles, higher peak external knee abduction moment, and higher internal rotation moments. Maturation also raises overuse and growth-related injury rates (Sever disease, Osgood-Schlatter, patellofemoral pain).

一个教练可以直接落地的心理社会结论A psychosocial finding coaches can act on

女性与女孩持续表现出更强的任务目标定向——以努力、学习与进步来定义成功；而男性与男孩的自我目标定向更强。自我目标定向与焦虑、紧张、压力、退出和倦怠呈正相关。因此，以努力与进步为框架的反馈，恰好契合女孩本就持有的成功定义，并与持续参与相关联。 Girls and women consistently report greater task goal orientation — defining success by effort, learning, and improvement — while boys and men report greater ego orientation. Ego orientation is positively associated with anxiety, tension, pressure, dropout, and burnout. Feedback framed around effort and improvement therefore aligns with how girls already define success, and is associated with continued participation.

• 女孩约 11 岁之前，采用早期多项目尝试而非早期专项化。Prescribe an early sampling approach over early specialisation up to ~11 years in girls.
• 初学者：从自重至 60% 1RM 起步，降低离心负荷；依动作能力而非年龄推进。Beginners: start at bodyweight to 60% 1RM with lower eccentric loading; progress on movement competency, not age.
• 为所有青少年周期化安排过渡期，以保障恢复与生长相关进程。Periodise transition periods for all youth to permit recovery and growth-related processes.
• 规律的中高强度负重活动以积累骨量，长期降低骨质疏松风险。Regular moderate-to-high-intensity weight-bearing activity to build bone mineral and reduce long-term osteoporosis risk.

成年：一扇会关上的窗口Adulthood: a window that closes

骨密度峰值通常在 25–30 岁达到；若缺乏恰当而持续的训练，骨骼肌质量与功能的年龄相关流失约从 30 岁开始。成年早期及之前，是通过负重与加载训练最大化骨密度的唯一窗口。此后的长期抗阻训练用以对抗骨骼肌流失——这既延长了运动员可以参赛的年限，也降低其损伤风险。 Peak bone density is typically reached by age 25–30, and age-related losses in skeletal muscle mass and function begin around age 30 without appropriate, consistent training. The window before and during early adulthood is the one chance to maximise bone density through weight-bearing and loaded exercise. Long-term resistance training thereafter counteracts muscle loss — extending the years an athlete can compete and reducing her injury risk.

妊娠与产后Pregnancy and postpartum

所有主要指南机构——ACOG、加拿大与澳大利亚指南、IOC 专家组——均将体能与力量训练描述为对大多数孕期及产后女性风险极小而收益增加。处方应以确认妊娠前即刻的体能水平为基准。 Every major guideline body — ACOG, the Canadian and Australian guidelines, the IOC expert group — describes conditioning and strength training as minimal risk with increased benefit for most women during pregnancy and postpartum. Prescription should be centred on the athlete's fitness level immediately before confirmation of pregnancy.

• 健康妊娠中，原本已进行高强度训练的女性在孕晚期耐受高强度运动良好——但在获得更多研究前，建议对超过最大心率 90% 保持谨慎。Vigorous third-trimester exercise is well tolerated in healthy pregnancies among women already training vigorously — but caution is advised above 90% of maximum heart rate pending more research.
• 中等强度抗阻训练可改善血糖、胰岛素利用与妊娠期糖尿病预防，并提升精力、减轻疲劳。Moderate-intensity resistance training improves blood sugar, insulin usage, and gestational diabetes prevention, and increases energy while reducing fatigue.
• 运动员恢复活动的速度快于活跃对照组——产后 6 周内；从事高冲击项目者，分娩并发症与会阴撕裂并不多于非运动员。Athletes return to activity faster than active controls — within 6 weeks postpartum — and high-impact-sport athletes have no more complications or perineal tears than non-athletes.
• 营养需求须超出维持妊娠代谢所需的每日额外 300 kcal 基线；哺乳期同理。Nutrition must exceed the extra 300 kcal/day baseline required to meet the metabolic demands of pregnancy, and again for lactation.
• 绝对禁忌证包括：26 周后前置胎盘、子痫前期、胎膜破裂、宫颈机能不全、重度贫血。Absolute contraindications include placenta previa after 26 wk, preeclampsia, ruptured membranes, incompetent cervix, and severe anemia.

围绝经期、绝经期与绝经后Peri-, meno-, and postmenopause

绝经通常发生在 40 至 58 岁之间，平均 51 岁，定义为末次月经后满一年。围绝经过渡期可持续 4–6 年甚至更久。雌二醇下降会提高骨质疏松、腹部脂肪堆积与不良血脂谱的风险，进而增加心血管疾病风险。 Menopause occurs typically between 40 and 58 years, averaging 51, defined as one year since the last menstrual period. The perimenopausal transition can run 4–6 or more years. Falling estradiol raises the risk of osteoporosis, abdominal adiposity, and poor lipid profiles — and thus cardiovascular disease.

声明的建议是：抗阻训练应聚焦于维持或提升肌肉质量与骨密度，这同时也会提升运动表现。最有效的方案将有氧与抗阻训练结合，且抗阻训练需具备足够的量与强度——包含大负荷阶段。若已确诊骨质疏松，进阶安排必须依其严重程度设计：某些动作（如脊柱屈曲）可能需要回避，可改用弹力带、悬吊训练器与徒手抗阻。 The statement's recommendation: resistance training should focus on maintaining or improving muscle mass and bone mineral density, which also enhances performance. The most effective programmes combine aerobic and resistance exercise, with resistance work of sufficient volume and intensity — including heavy-load phases. Where osteoporosis is established, progression must be designed around its severity: certain movements (e.g. spinal flexion) may need avoiding, with bands, suspension trainers, and manual resistance as alternatives.

二、损伤考量2. Injury considerations

以下是在女性运动员中发生率或发病率更高的损伤。正是这些数量级，使得本声明将训练方案的交付本身视为一种风险削减手段，而不仅是表现提升手段。 These are the injuries that present at higher rate or incidence in female athletes. The magnitudes are why the statement treats programme delivery as a risk-reduction instrument, not merely a performance one.

前交叉韧带（ACL）Anterior cruciate ligament

多数 ACL 损伤为非接触性，发生在落地或变向的减速阶段。风险是多因素的——激素、神经肌肉、解剖、生物力学与环境——其中神经肌肉因素占主导。而训练能够介入的，只有神经肌肉与生物力学两类因素。 Most ACL injuries are non-contact, occurring in the deceleration phase of landing or cutting. Risk is multifactorial — hormonal, neuromuscular, anatomical, biomechanical, environmental — with neuromuscular factors dominating. Only neuromuscular and biomechanical factors can be addressed by training.

Pappas 等人对 721 名女性运动员进行非预期变向任务筛查，发现约 40% 不存在任何生物力学缺陷。其余为：24% 股四头肌主导 + 单腿主导，22% 躯干主导 + 单腿主导，14% 单纯韧带主导。缺陷分型使训练方案能够精确针对出问题的动作模式。 Screening 721 female athletes on an unanticipated cutting task, Pappas et al. found ~40% carried no biomechanical deficit. Of the rest: 24% quadriceps + leg dominance, 22% trunk + leg dominance, 14% ligament dominance alone. Deficit profiling lets programmes target the specific movement pattern at fault.

声明的建议是：损伤预防方案应超越场地热身层面，进入周期化、个体化、可变化的长期运动能力发展。力量训练针对髋、膝、踝肌群，并纳入单侧动作、离心动作，以及跳/单腿跳后保持的落地与稳定模式。务必让女性运动员获得渐进超负荷，在旋转变向类及跳跃落地频繁的项目中尤其如此。 The statement's recommendation: injury prevention programmes should progress beyond field-based warm-ups to long-term athletic development that is cyclic, individualised, and variable. Strength work targets hip, knee, and ankle musculature, incorporating unilateral exercises, eccentric movements, and jump/hop-and-hold patterns for landing and stabilisation. Ensure female athletes are exposed to progressive overload, particularly in pivoting and jump-landing sports.

骨应力性损伤Bone stress injuries

女性运动员的发生率持续高于男性。RED-S（运动相对能量不足）是关键促成因素。周期化的冲刺、增强式训练与下肢力量训练具有成骨保护作用。赛季中的负荷变化必须与能量可用性一并解读。 Consistently higher in female than male athletes. A key contributor is RED-S. Periodised sprinting, plyometrics, and lower-extremity strengthening are osteogenically protective. Workload changes across the season must be read together with energy availability.

脑震荡Concussion

在可比项目中，女性运动员的发生率高于男性——足球、篮球、垒球与冰球最高。人对人接触率相似，但女性运动员的器材接触为 2.5 倍、场地接触为 2 倍。恢复时间与症状持续时间也更长。 Incidence is higher than in male athletes in comparable sports — highest in soccer, basketball, softball, and ice hockey. Player-to-player contact rates are similar, but equipment contact is 2.5× and surface contact 2× higher among female athletes. Recovery time and symptom duration are longer.

• 更高的颈部力量与更低的脑震荡风险相关——应纳入颈部肌群训练。Higher neck strength is associated with lower concussion risk — include cervical muscle exercises.
• 视觉与感觉运动训练对降低整体损伤率显示出前景；更快的反应时有助于运动员预判并躲避撞击。Vision and sensorimotor training show promise for reducing overall injury rates; faster reaction time helps athletes anticipate and move away from impact.
• 多次脑震荡后应增加敏捷训练——女性运动员双任务步态节奏的变化更大。Prescribe more agility training after multiple concussions — dual-task gait cadence changes are greater in female athletes.
• 软壳头具未能降低头部损伤，反而增加了其他所有身体部位的损伤风险。Soft-shell headgear showed no reduction in head injuries and increased injury risk to all other body regions.
• 脑震荡后可能出现月经周期紊乱，应纳入管理与重返赛场的评估指标。Menstrual cycle disturbances can follow concussion and belong in management and return-to-play criteria.

髌股疼痛综合征（PFPS）Patellofemoral pain syndrome

多因素成因：下肢力线不良、膝伸肌力量失衡与离心控制不足、髋部无力与臀肌激活不良、核心功能障碍。青少年女性的早期专项化会较多项目同龄人提高前膝痛风险。研究显示各类深蹲在屈曲 60 至 90 度区间均加重 PFPS 疼痛；将幅度限制在 0–60° 并加入外翻控制训练，可在根本病因得到处理之前先行减轻疼痛。 Multifactorial: lower-extremity malalignment, knee extensor imbalance and weak eccentric control, hip weakness and poor gluteal activation, core dysfunction. Early sport specialisation in adolescent girls raises anterior knee pain risk versus multisport peers. Squatting increased PFPS pain across all squat types from 60 to 90 degrees of flexion; restricting to 0–60° and adding valgus-control work reduced pain while the underlying cause is addressed.

乳房损伤——一个被严重低报的类别Breast injuries — an under-reported category

至少 50% 的大学生运动员报告过乳房相关损伤，但不足 10% 会上报，仅 2.1% 得到处理。83% 的女性运动员自评乳房与内衣知识低于平均水平；某项研究中 85% 的受试者穿着不合身的内衣。内衣知识教育可切实提升合身度判断与支撑效果——这是一项低成本、且完全在教练能力范围内的干预。 Breast-related injury has been reported in at least 50% of collegiate athletes, but fewer than 10% report it and only 2.1% receive treatment. Eighty-three percent of female athletes rated their breast/bra knowledge as below average; 85% in one study were wearing ill-fitting bras. Bra education measurably improves fit accuracy and support — a low-cost intervention squarely within a coach's reach.

三、健康考量3. Health considerations

运动相对能量不足（RED-S）Relative Energy Deficiency in Sport

即原先的「女运动员三联征」。低能量可用性定义为低于 30 kcal/kg 去脂体重。患病率相当惊人：在 9 个项目的 112 名准精英与精英女性运动员中，87% 至少存在一项指标，81% 存在 1–3 项，33% 已被诊断精神疾病。 Formerly the Female Athlete Triad. Low energy availability is defined as <30 kcal/kg fat-free mass. Prevalence is striking: in 112 pre-elite and elite female athletes across 9 sports, 87% had at least one indicator, 81% had one to three, and 33% had a diagnosed psychiatric condition.

RED-S 抑制生殖与甲状腺激素分泌，升高生长激素与皮质醇；下丘脑与垂体的抑制可导致月经停止。过度训练综合征与 RED-S 共享通路、症状与诊断复杂性——这正是早期干预至关重要的原因。热量限制下的抗阻训练具有保留去脂体重的作用；与高冲击运动结合则有助于维持骨密度。 RED-S suppresses reproductive and thyroid hormone production and raises growth hormone and cortisol; hypothalamic and pituitary suppression can cease menstruation. Overtraining syndrome and RED-S share pathways, symptoms, and diagnostic complexity — which is exactly why early intervention matters. Resistance training under caloric restriction has a lean-mass sparing effect; combined with high-impact exercise it helps maintain bone density.

盆底功能障碍与尿失禁Pelvic floor dysfunction and urinary incontinence

高冲击项目（篮球、排球、手球、体操、田径、格斗）、大负荷训练与更长训练时数均会提高发生率。尿失禁发作可在 6–12 周内显著减少，盆底肌力量亦可提升。应教会运动员正确启动盆底肌，并理解其与膈肌、髋部及腹部肌群之间的协同关系。 High-impact sports (basketball, volleyball, handball, gymnastics, track, combat sports), heavy-load training, and higher training hours all raise incidence. UI episodes can be greatly reduced and pelvic floor muscle strength increased within 6–12 weeks. Athletes should be taught to engage the pelvic floor properly and to understand its interaction with the diaphragm, hip, and abdominal musculature.

睡眠Sleep

44–52% 的运动员报告睡眠质量差、失眠与日间嗜睡。女性运动员的入睡潜伏期更长、日间功能障碍更重。训练后总睡眠时间下降见于 63% 的研究，赛后下降见于 75%。经期对卫生用品的担忧本身即独立恶化睡眠。睡眠卫生教育可即时改善精英女性运动员的睡眠质量。 Between 44–52% of athletes report poor sleep quality, insomnia, and daytime sleepiness. Female athletes show longer sleep onset latency and greater daytime dysfunction. Total sleep time decreased post-training in 63% of studies and post-competition in 75%. Concern about sanitary products during menses independently worsens sleep. Sleep hygiene education acutely improves sleep quality in elite female athletes.

心理健康Mental health

抑郁与焦虑在女性中的患病率是男性的 2 倍以上；高水平女性运动员自我报告抑郁症状的可能性是男性同行的两倍。NCAA 2021 年数据显示，近 40% 的女性学生运动员报告在过去 30 天内经历过难以承受的焦虑，男性为 22%。 Depression and anxiety are over 2× more prevalent in women than men; high-level female athletes are twice as likely to self-report depressive symptoms as male counterparts. NCAA data (2021) found nearly 40% of female student-athletes reported overwhelming anxiety in the previous 30 days, against 22% of male student-athletes.

声明的要求是：体能训练从业者必须了解心理健康问题的常见表现形式，营造滋养运动员心理健康的环境，并消除寻求支持与治疗的污名。教练处在一个独特的观察位置——他们能看到行为、外表与表现的变化——其职责是识别与转介，而非治疗。 The statement's requirement: practitioners must have an awareness of how mental health issues commonly manifest, promote environments that nourish athletes' mental health, and destigmatise support and treatment. Coaches sit in a uniquely observant position — they see behaviour, appearance, and performance change — and their role is recognition and referral, not treatment.
