Abstract
Oral contraceptive pills (OCP) are very popular in female athletes not only for contraceptive effects but also due to the possibility of cycle manipulation. Moreover, it is debatable whether the manipulation of the menstrual cycle has a beneficial effect on exercise performance. Therefore, the aim of this study was to investigate potential differences in knee-extensor and flexor strength performance of first division team sport athletes between phases of the oral contraceptive cycle. Sixteen female handball players (age: 23.3 ± 3.1 years; body mass: 67.0 ± 8.52 kg; body stature: 1.68 ± 0.05 m) using a monophasic OCP participated in strength performance tests, once during OCP consumption (CONS) and once during withdrawal (WITH). Tests were performed on a dynamometer to measure knee-extensor and flexor maximal voluntary isokinetic and isometric torque. Prior to each test, body mass was assessed, and venous blood samples were collected. Wilcoxon signed-rank test and magnitude-based inferences have been conducted to analyze differences between WITH and CONS. Significance was accepted at P < 0.05. No significant differences between oral contraceptive cycle phases of knee-extensor and flexor strength parameters and body mass have been indicated (all at P > 0.05). Follicle-stimulating hormone (FSH) (P = 0.001) and luteinizing hormone (P = 0.013) were significantly higher in WITH, whereby estradiol and progesterone showed no significant difference between phases (both at P > 0.05). These results support the notion that knee-extensor and flexor isokinetic and isometric strength performance does not differ between phases of oral contraceptive cycle in well-trained team sport athletes. OCP intake is suggested to cause a stable but downregulated hormone cycle, which has no effect on knee-extensor and flexor strength when comparing oral contraceptive cycle phases. Therefore, manipulation of the female cycle using OCP in order to achieve a higher knee-extensor and flexor strength performance does not seem to be justified; however, it is currently unclear if cycle manipulation might affect other physiological systems.

Quantitative Analysis of Patellar Tendon After Total Knee Arthroplasty Using Echo Intensity: A Nonrandomized Controlled Trial of Alpine Skiing. J Arthroplasty 2020; 35:2858-2864. [PMID: 32561260 DOI: 10.1016/j.arth.2020.05.052] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 05/10/2020] [Accepted: 05/20/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Despite the knee extensor weakness, less attention has been paid to the evaluation of patellar tendon after total knee arthroplasty (TKA). We previously observed patellar tendon hypertrophy after TKA. The purpose of this study is to reanalyze these ultrasound data to detect whether brightness mode ultrasound imaging reflects pathological changes of the patellar tendon after TKA. METHODS Twenty-eight participants with post unilateral TKA were assigned to an intervention group or control group. The intervention group underwent a 12-week skiing program. Patellar tendon mechanical properties were obtained by combining isometric dynamometry, ultrasound imaging, and electromyography in operated knee and nonoperated knee. Luminosity ratio (LR) was measured using echo intensity in a relaxed and maximally loaded phase. RESULTS Baseline comparisons revealed significant effects of the surgical side (P < .001) and loading phase (P = .017), but no interaction between leg and phase (P < .149). LR of the operated knee was significantly lower than LR of the nonoperated knee in relaxed (P < .001) and maximally loaded phases (P = .003). In addition, there was a significant correlation between LR of maximum phase and isometric knee extension torque (r2 = 0.156, P = .038). However, LR was not related to patellar tendon stiffness, Young's modulus, or strain. There was a significant time effect in knee extension torque, but no time effects on LR and tendon force. CONCLUSION Patellar tendon LR is decreased along with degenerative change after TKA. Ultrasound imaging provides a promising metric to acquire in vivo patellar tendon pathological assessment after TKA.

Feasibility of Ski Mountaineering for Patients Following a Total Knee Arthroplasty: A Descriptive Field Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16091582. [PMID: 31064129 PMCID: PMC6540216 DOI: 10.3390/ijerph16091582] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 04/30/2019] [Accepted: 05/02/2019] [Indexed: 01/04/2023]
Abstract
Background: Total knee arthroplasty (TKA) is socially relevant due to its high prevalence, high incidence and the affected population. A subpopulation of TKA patients exists that strives to be active and also return to sports after total joint replacement. In this context, a further group of TKA patients is interested in high-impact physical activities and want to proceed with such activities even after surgery. Focusing on winter sports, there is still a lack of evidence on whether ski mountaineering is feasible for this subgroup of patients. Therefore, this feasibility study examines the effects of moderate ski mountaineering on strength, balance, functional abilities and mental health in persons following a TKA. Methods: Eight patients (six males, two females; median age, 63 ± Interquartile range 9 years) with TKA were included in this study. The volunteers, who were pre-selected for a 7-day holiday in Sankt Johann (Tyrol, Austria), participated in five guided ski mountaineering tours. Statistical analyses of non-parametric longitudinal data were performed using analysis of variance. For gait parameters and the Feeling Scale, one-factor longitudinal models were used. Statistical significance was set at the level of p < 0.05. Results: A significant decrease in the S3-Check MFT stability index (p = 0.04), a significant increase in general well-being (p = 0.05), and a trend towards a decrease in general stress (p = 0.1) were detected, while all other parameters were unaffected. Conclusion: A 7-day recreational ski mountaineering holiday had no negative effects on ski-experienced patients with TKA and seemed to increase well-being. Further studies should focus on larger groups and use controlled designs. Additionally, long-term effects should be evaluated.

Abstract
PURPOSE AND HYPOTHESIS Improvements in pain, function and sports activity are the main goals of patients following total knee arthroplasty (TKA). Participation in sports has become an increasingly important contributor to patients' quality of life (QoL). Hiking is one of the most popular summer activities among elderly people in alpine regions. Consequently, this randomized controlled trial investigates the impact of a 3-month guided hiking programme on patients' functional abilities and QoL following TKA. It was hypothesized that patients who participate in this programme would demonstrate improvements in functional and QoL parameters compared with a control group. METHODS Forty-eight TKA patients were included and randomized into either the intervention group (IG; n = 25) or the control group (CG; n = 23). The IG participated in a 3-month hiking programme (2-3 times a week), whereas the CG performed activities of daily living. The stair climb test (SCT), QoL questionnaires and isokinetic force measurements were completed at three time points (i.e. pre-test, post-test, retention-test). ANOVAs for repeated measurements were conducted for the SCT results. The Friedman test and the Mann-Whitney U test were performed for the QoL parameters. RESULTS After the 3-month hiking programme, the IG achieved faster overall walking times on the SCT. The time decreased from 4.3 ± 0.6 s (pre-test) to 3.6 ± 0.4 s (post-test) for the stair ascent (p = 0.060) and from 3.6 ± 0.6 s (pre-test) to 3.2 ± 0.5 s (post-test) for the stair descent (p = 0.036). The IG showed significant improvement on some of the subscales of the Knee Injury and Osteoarthritis Outcome Score from pre-test to retention-test (p < 0.01). In the CG, no significant changes were observed (n.s.). CONCLUSIONS The results indicate moderate improvement in the functional abilities and QoL of TKA patients who participated in a 3-month guided hiking programme compared with the patients in the CG. Hiking did not have any acute detrimental effects on the TKA patients during this study period. LEVEL OF EVIDENCE II.

Abstract
INTRODUCTION To counteract the winter activity deficit, we set out to analyze cardiorespiratory and metabolic responses of two high-intensity training (HIT) protocols during alpine skiing (AS), cross-country skiing (XCS), and indoor cycling (IC) and the effects of sex, age, and fitness level in this comparison. METHODS Nineteen healthy subjects (two age and fitness groups, both sexes) performed AS, XCS, and IC with measurements of oxygen uptake (V˙O2), energy expenditure (EE), HR, lactate, blood glucose and rate of perceived exertion, determined during 4 min of continuous HIT (HITc: 90% HRmax for XCS and IC or short turn skiing during AS) or 10-min intermittent HIT [HITint: 5 × 1 min high intensity (>90% HRmax or short turn skiing), 1 min active recovery]. RESULTS During all three exercise modes and irrespective of HIT protocols, sex, age, and fitness, participants were able to reach exercise intensities >90% HRmax and >84% V˙O2max. In all exercise modes 10-min of HITint with a 10-min postexercise O2 consumption phase resulted in greater mean EE per minute compared to 4-min HITc with 10 min postexercise O2 consumption. When applying the same HIT loading and recovery pattern to all three exercise modes, EE during approximately 1:15 h of AS was equivalent to about 1:00 h of either XCS or IC. CONCLUSIONS Across all exercise modes and HIT protocols, high cardiorespiratory and metabolic responses were achieved regardless of age, sex, or fitness. EE during AS can be maximized by choosing the skiing mode "short turn skiing" in combination with an HITint to prolong the duration of continuous high-intensity loading during each descent. Therefore, all exercise modes and both HIT protocols are applicable and feasible in a broad spectrum of healthy subjects.

Abstract
Physical self-concept in the elderly is assumed to be structured in terms of different domains and to contribute substantially to life satisfaction. However, little is known about the role of the physical self-concept in older persons that are engaged in physical activity while suffering from typical age-related impairments or chronic diseases. The present study aimed to investigate the structure of physical self-concept in a group of older persons with total knee arthroplasty (TKA), its development throughout a 12-week skiing intervention, and its importance to life satisfaction. Factor analyses of the present data reveal that the physical self-concept consists of four dimensions addressing strength, flexibility/coordination, endurance, and sportiness. One higher order factor extracted by hierarchical factor analyses reflects a global physical self-concept. The 12-week skiing intervention had no substantial impact in terms of an improvement of self-concept. Life satisfaction is best predicted by positive changes in the subjective ratings between pre- and post-test (i.e., global physical self-concept, flexibility and coordination, and perceived sportiness) and not by objective physical performance (isokinetic strength, endurance, or coordination). Results support the assumption that physical self-concept of older people with TKA is only marginally sensitive to a 12-week skiing intervention.
