Abstract Purpose Anthropometrics, aerobic fitness and muscle strength are measured in one-third of all 18-year-old Norwegian men and women during yearly selection for compulsory military service. The large sample size and geographical representativity make these data valuable for reference. The main purpose of this study was to present reference data for anthropometrics and physical fitness in young Norwegian men and women. Methods All 154,659 subjects (66% men and 34% women, 17–21 years old) who completed physical examinations at conscript selection from 2011 to 2019 were included in the study. Body mass index (BMI) was calculated from height and weight measurements. Peak oxygen uptake (VO2peak) was estimated from performance on a maximal treadmill test. Muscle strength was measured by isometric chest and leg press, or seated medicine ball throw, standing long jump and pull-ups. Results Mean BMI (SD) was 23.1 (3.4) and 22.9 (3.3) kg·m−2 in men and women, respectively (P < 0.001), and 24% of men and 21% of women had a BMI ≥ 25 kg·m−2. Estimated VO2peak was 52.9 (4.6) and 42.7 (3.9) mL·kg−1·min−1 in men and women, respectively (P < 0.001). Men performed significantly better than women on all muscle strength tests, with corresponding effect sizes varying from 1.14 for isometric leg press to 2.96 for seated medicine ball throw. Conclusion The presented reference data on physical fitness in young Norwegian men and women can be used to evaluate population health, serve as reference material for future studies and describes sex differences in several physical fitness parameters.

The concurrent training led to beneficial effects on aerobic fitness and muscle strength. However, its effects on blood pressure (BP) and autonomic control marks are little studied. This study aimed to evaluate the concurrent training effects on BP, autonomic control, aerobic fi tness and muscle strength of middle-aged men and women. Thirty-two volunteers (51.4 ± 4.2 years, systolic BP 115 ± 12 mmHg and diastolic BP 78 ± 8 mmHg) were divided into 4 groups of 8 volunteers: male concurrent training (MCT), female concurrent training (FCT), male sedentary control (MSC) and female sedentary control (FSC) groups. A minimum absence of menstruation for 12-months was required. Concurrent training, six resistance exercise for whole body followed by 30 min of jogging and/or running at 55%–85% of VO2peak, was performed three times a week. The main assessments were rest BP and cardiovascular autonomic markers evaluated through heart rate variability (iRR, LF, HF, LF/HF, RMSSD, pNN50, SD1 and SD2), aerobic fitness measured by cardiorespiratory test (VO2peak) and muscle strength by one repetition maximum (1-RM - arm curl, bench press and leg press). The concurrent training did not change any cardiovascular variables. Regarding fitness the MCT and FCT groups demonstrated signifi cant improvement in VO2peak (13.12% e 8.51%, respectively). Muscle strengthimproved significantly in the MCT group in all three exercises (arm curl: 26.53%; bench press: 25.04%; leg press: 65.37%), while FCT in just two exercises (arm curl: 12.79%; bench press: 17.25%). Although concurrent training appears to be a good alternative for inducing improvements in various physical fitnessvariables in male, its can induce concurrence in leg strength of female. Concurrent training is not an effective strategy to improve BP and autonomic nervous system.

This study aimed to determine which of four selected physical fitness variables, would be most associated with blood pressure changes (systolic and diastolic) in a large sample of adolescents. This was a descriptive and cross-sectional, epidemiological study of 1,117 adolescents aged 14–19 years from southern Brazil. Systolic and diastolic blood pressure were measured by a digital pressure device, and the selected physical fitness variables were body composition (body mass index), flexibility (sit-and-reach test), muscle strength/resistance (manual dynamometer), and aerobic fitness (Modified Canadian Aerobic Fitness Test). Simple and multiple linear regression analyses revealed that aerobic fitness and muscle strength/resistance best explained variations in systolic blood pressure for boys (17.3% and 7.4% of variance) and girls (7.4% of variance). Aerobic fitness, body composition, and muscle strength/resistance are all important indicators of blood pressure control, but aerobic fitness was a stronger predictor of systolic blood pressure in boys and of diastolic blood pressure in both sexes.

This study was aimed at determining the description of predominant physical component profile (physical fitness, fat thickness, agility, muscle endurance, flexibility, power, muscle strength and balance) of the Persipura Junior Football Athletes. This study used a survey of PERSIPURA Junior Football athletes involving 39 people. The inclusions of the athletes inculde male gender, aged 21 years, height 177 cm, an ideal body weight, a healthy body, and moderate to good categories of physical fitness. The instrument used in this study were dynamometer for muscle strength; crunches for muscular  endurance, push-ups, squat jumps, beam side step for agility, flexometer for flexibility, vertical jump for power, and 2.4 km running test for physical fitness. The results showed that the Persipura Junior Football athletes had a good physical fitness, less triceps fat thickness, a normal sub scapular thickness, a normal supra iliaca thickness, lack of agility, a good endurance of arm and shoulder muscles, a good endurance of abdominal muscles, an adequate flexibility, a perfect vertical jump muscle power, a good medicine ball muscle explosive power, a good full muscle strength, lack push muscle strength, and a very good balance. It concludes that to gain an optimal predominant physical component, sports science with measurable and well-programmed exercises should be applied, so that the physical component of triceps fat thickness, agility, and push muscle strength could increase. Abstrak Penelitian ini bertujuan  untuk mengidentifikasi Profil Komponen Fisik Predominan (Kebugaran Jasmani, Ketebalan Lemak, Kelincahan, Daya Tahan Otot, Kelentukan, Daya Ledak Otot, Kekuatan Otot dan Keseimbangan) Atlet Pemain Sepak Bola Persipura Junior.

The aim of this study was to identify the relationship between health-related physical fitness components (aerobic fitness, muscle strength, flexibility, and body fat) and resting heart rate (RHR) in Brazilian adolescents. The study included 695 schoolchildren (14–19 years) from public schools of the city of São José, Brazil. RHR was evaluated using an automated oscillometric sphygmomanometer. Aerobic fitness was assessed by the modified Canadian Aerobic Fitness Test; muscle strength was measured by handgrip dynamometer; flexibility was assessed by the sit-and-reach test; and body fat was assessed indirectly by sum of two skinfold thicknesses (triceps and subscapular). Sociodemographic variables, habitual physical activity, sexual maturation, and body mass index were the covariates. Cardiorespiratory fitness (β = -0.11; 95%CI: -0.14, -0.08) and handgrip strength (β = -0.10; 95%CI: -0.18, -0.01) were inversely associated with RHR in boys. For girls, cardiorespiratory fitness (β = -0.09; 95%CI: -0.12, -0.06) was inversely associated with RHR. In both sexes, body fat (β = 0.50; 95%CI: 0.25, 0.75 for boys; β = 0.17; 95%CI: 0.36, 2.72 for girls) was directly associated with RHR. The RHR is measured more easily than the physical fitness tests, so it is recommended to assess adolescent’s heath in large surveillance systems.

Regular exercise during school hours is encouraged since childhood obesity has reached epidemic proportions. Moreover, a great majority of adolescents do not meet the recommendations for moderate-to-vigorous physical activity. The present study aimed to determine the effects of school-based high-intensity interval training (HIIT) and nutrition intervention on body composition and physical fitness in overweight adolescent girls. Forty-eight girls were included in the study, of whom 24 (age = 15.5 ± 0.7 years) were randomized to a experimental group (EXP) (HIIT and nutrition intervention school-based program) and 24 (age = 15.7 ± 0.6 years) to a control group (CON) that maintained their usual physical education activities. HIIT consisted of 10 stations of own bodyweight exercise and was done three times per week for eight weeks. Moreover, the EXP participated in the nutrition program led by a nutritionist two times a week. Apart from body composition assessment, participants performed countermovement jump (CMJ), medicine ball throw, hand-grip test, and Yo-Yo Intermittent Recovery Level 1 Test (YYIRT1). A significant effect of group (EXP vs. CON) x time (pre vs. post) interaction was observed for weight [F(1,44) = 7.733; p = 0.008], body mass index [F(1,44) = 5.764; p = 0.020], body fat (in kg) [F(1,44) = 17.850; p < 0.001], and body fat (in %) [F(1,44) = 18.821; p < 0.001]. Moreover, a significant interaction was observed for the medicine ball throw [F(1,44) = 27.016; p < 0.001] and YYIRT1 [F(1,44) = 5.439; p = 0.024]. A significant main effect for time was found for hand grip [F(1,44) = 9.300; p = 0.004] and CMJ [F(1,44) = 12.866; p = 0.001].The present study has demonstrated that just eight weeks school-based HIIT and nutrition intervention, including three sessions a week, can improve body composition and muscular and physical aerobic performance in overweighted adolescent girls.

Introduction: Hip fractures predominantly occur in the geriatric population and results in increased physical inactivity and reduced independency, largely influenced by a downward spiral of ambulatory capacity, related to loss of skeletal muscle strength and postural stability. Thus, effective postoperative treatment, targeting improvements in muscle strength, is sought after. Materials & Methods: Twenty-one hip fracture patients (>65 yr) were randomized to 8 weeks of either conventional physiotherapy control group (CG), or leg press and hip abduction maximal strength training (MST) 3 times per week. MST was performed applying heavy loads (85-90% of 1 repetition maximum; 1RM) and 4-5 repetitions in 4 sets. Maximal strength (bi- and unilateral 1RM), postural stability (unipedal stance test; UPS), and DEXA-scan bone mineral content/ density (BMC/BMD) were measured before and after the 8-week rehabilitation. Results: Both MST and conventional physiotherapy improved bilateral leg press 1RM by 41 ± 27 kg and 29 ± 17 kg, respectively (both p < 0.01), while unilateral leg press 1RM only increased after MST (within group and between groups difference: both p < 0.05). MST also resulted in an increase in abduction 1RM in both the fractured (5 kg, 95%CI: 2-7; p < 0.01) and healthy limb (6 kg, 95%CI: 3-9; p < 0.01), while no such improvement was apparent in the CG (between groups difference: p < 0.01). Finally, MST improved UPS of the fractured limb (p < 0.05). No differences were observed in BMC or BMD following the 8 weeks. Discussion: Early postoperative MST improved lower extremities maximal muscle strength more than conventional physiotherapy and was accompanied by improvements in postural stability. Conclusion: Implementing MST in early rehabilitation after hip fracture surgery should be considered as a relevant treatment to curtail the downward spiral of reduced ambulatory capacity typical for this patient group, possibly reducing the risk of recuring falls and excess mortality.

The primary purpose of this study was to examine the effects of an exercise program on physical fitness, psychosocial factors, and symptoms in two men with fibromyalgia syndrome (FMS). An interventional case study research design was used to collect data on physical fitness, psychosocial factors, and symptoms at intervals throughout a 14-month period. Raw scores and raw score averages, devoid of statistical manipulation, are presented to display real individual results. The secondary purpose of the study was to discuss how these two men tolerated the program in comparison to women in a similar program. This is important because data on men with FMS appear to be unavailable, because the greater majority of participants in FMS programs are women. Results support that these two men benefited from the program and that differences between men and women with FMS should be considered relative to the conduct of exercise programs for these groups.

The Relationship

ABSTRACT Introduction Concussion has become the signature injury facing the U.S. military. However, little is understood about the relationship between military fitness and concussion recovery. The current study examined the recoveries of cadets at a U.S. Service Academy to determine whether preinjury physical fitness improved recovery and whether recovery was associated with post-injury physical fitness measures. Methods Participants were enrolled in a longitudinal study of concussion. Aerobic Fitness Test (AFT) and Physical Fitness Test (PFT) data were used to estimate cadet fitness. Survival analysis evaluated significant estimators of concussion recovery time. Linear regression models were used to explore the relationship between recovery duration and change in physical fitness scores. Results Between 2014 and 2017, 307 (n = 70; 22.80% Women) cadets who had sustained a concussion were enrolled. Preinjury physical fitness was not significantly associated with recovery duration (P &gt; .05). Men and intercollegiate cadets took fewer days to reach recovery milestones. Compared to women, men had greater decrements in the Aerobic Fitness Test total score (P &lt; .05) and increased 1.5-mile time postconcussion (P &lt; .05). Women had greater decreases in push-ups postconcussion compared to males (P &lt; .05). There was a trend for a negative association between days until asymptomatic and change in the Physical Fitness Test score (P = .07). Conclusion Preconcussion physical fitness levels do not appear to impact concussion recovery time among a highly physically fit cohort. Possible methods to reduce the effect of symptom duration on strength-related physical fitness should be investigated along with evaluating reductions in strength as a possible mechanism for postconcussion injury risk.
